Hello Lichen group:

I am going to be putting together another "Lichen Weekend" for the
Spring/summer of 2008.  Let's say end of May, early June.

As in the last two years before, we will explore a park, preserves,
etc. for lichens on a Saturday AND a Sunday.  Staying
overnight/camping somewhere in the general vacinity of the
park/preserve we are visiting on the Saturday night.


So far we have spent time in Kane and McHenry County in Illinois, but
never got to do Will County last fall.

So, please send me me your suggestions for another Lichen Weekend in
2008!

Rich



P.S.  we have been invited to visit Peoria, IL in March.  They have
cabins we can stay at.  VERY steep hills in Peoria!

May add Illinois Beach State Park, near Zion, IL for a hike in April.


Happy New Year!

Hi All,

   A student of mine had a field trip to the Indiana Dunes and
collected some twigs with lichen on them.  One that caught my eye
was unfamiliar to me and I'm looking for assistance in identifying
it.  I've uploaded the file to the photos section of the website.
Sorry the picture is not great, it is taken through a microscope in
hopes of giving viewers a little more detail.  I didn't draw a scale
bar on the picture, however the largest apothecia are 0.5 mm in
diameter.

   I've tentatively identified it as lecanora umbrina, however based
on Rich's paper on lichen flora in Chicago Parks, this species seems
to be infrequent at best.  I've spot tested with KOH and both cortex
and apothecia are K-.  I have no idea how to assess spores and
septate, so after getting through Rich's key to question 2
under `crustose lichen with apothecia' I used the official `hunt and
peck' procedure of looking for pictures that came closest.  No good
pictures of the umbrina, however Rich's lecanora key points me in
this direction.  I'd appreciate any enlightenment.

Hi everyone,

I added a photo to my photo folder today, not sure what they are, but
they were growing on the ground in the St. Mihiel East forest preserve
near Oak Forest in the south suburbs.

Anyone know what it is? To help go directly to it, it's at

Thanks,

This pic looked better before I compressed it but would anyone like to
take a shot at id-ing these guys?

Looks like two different green ones but it's not obvious in the pic.

The lichen in Jack's photo of the Hummingbird nest is "Parmelia
sulacata"  a foliose lichen.

Rich

I published the "Lichens of Ten Chicago Parks" last year and in my
studies I found 25 lichens at North Park Village.

11 are crustose and 14 are foliose.  No fruticose.

Rich Hyerczyk

YES folks the overnighter at McHenry COunty is on. Oct 14-15.  We'll
visit a few local natural areas, and stay overnight.  This is
optional - the overnight.  You can also just go on the field trips
only.

I had to find enough people to run it.  We now have at least 9, so it
will be on.

Look for details next week.

Rich

Hello Jack -
Glad you're with us - I don't know about Marengo, but there are British
Soldiers in the Western suburbs in Dupage County, also I've heard they are
found at the Indiana dunes.  And lots of other lichens in Chicago proper -
Rich has led a number of lichen walks on the South Side of Chicago, most
of us here are beginners but it's a lot of fun.

Is the overnight trip in October still planned?  I haven't heard
anything about it since May.  When do we get additional details?

Interesting as I lived on the NW side (Montrose and Austin) and never
saw a lichen in the neighborhood.

Don't believe there were any at North Park Village where we volunteered
either.

As a point of interest, the most interesting lichen we have found around
here is at http://schmidling.com/hummer.htm

Welcome Jack,

Yes there are lichens in Chicago as in Chicago proper.  I haven't seen
any of the British Soldiers in the city.  But I have seen some
crustose lichens though pretty sparse, and of course Candelaria is
everywhere.  I guess I should post some of the Chicago lichens I've
seen.  Not that one can identify them from my snap shot.  But it's a
pretty frequent sight at UIC on the trees anyway.

Of course as you get farther away, you get more variety of Lichens.
So DuPage has some nice specimens.  I would assume McHenry would be rife.

Rick is the expert and you are in good hands!  I think he did
something for the Chicago Park District.

Mary K

I have only seen 3 species out here in about 10 years so it should be
pretty easy to remember them once I learn them.  For some reason, I
just have not taken the trouble.

Would you blelieve, they lead me to a new lichen.  It was red/orange
and growing on a Maple tree.  I took a pic but haven't gotten around
to doing anything with it yet.

Hello Jack,

I am looking forward to meeting you in McHenry Co. I
go out with Rich a lot, but don't have a good memory
for lichen names, so I don't know that many. I do
enjoy the walks, though, and you should go to one of
his talks, too. I don't know when the next one is, but
he posts them.

I visited your web site, and like your pictures.(I
always wanted a sheep.)

See you soon, Sally Natoli

Hi All,

Never occurred to me to look for a lichen group on Yahoo.

Although an amateur naturalist all my life, I must confess that I can
not think of the name of a single lichen  other than British Soldiers
and my wife had to remind me of that one.

I am looking forward to the lichen tour in McHenry County next month for
a bit of a crash course.

I have been doing a Photo of the Week for about 10 years and am always
looking for new photo ops.

We had a nice bushy looking lichen on our trail that we nursed along for
a few years but it finally disappeared this year.  Never occurred to me
to take a picture of it and it was unlike any others around here.

In browsing our library today I found a classic that I forgot that I had.

It was published by the Chicago Academy of Sciences and called "Bulletin
No1 of the  Geological and Natural History Survey" "The Lichen Flora of
Chicago and Vicinity.  published in 1896.  I suppose there might have
been some lichens in Chicago then?

Some years ago we were friends of the Academy and had the opportunity to
browse through and take publications that they were going to throw out.
   We also have a collection of this sort of pubs on mosses of the area.

Anyway, nice to find the group and real glad Al Gore invented the Internet.

Hello all,

   As some of you already know, I'm exploring ways of using lichen to
assess air quality in south side Chicago.  Over the next six weeks,
high school students will be participating in a college preparation
program here at CSU, where one of their research projects will be to
collect some lichen information.  I would like to give a brief
overview of our procedure for comments and suggestions.

   Due to my nascent lichen identification skills, we are limiting
the breadth of the lichen to be used in this pilot study to those
that are most commonly found and relatively easily identified - P.
stallaris, P. millegrana, C. concolor, and X. fallax/fulva.  I
imagine that if I can get high school students to be able to
identify 4 or 5 lichen species and be able to say "I know that's a
lichen, just not one that I can ID" I have made huge advances in our
hobby.

   The students will take belt transects at 1.4 and 0.5 m on
cottonwood trees on the CSU campus (we have several hundred
cottonwoods spread across the campus, thus its selection as
substrate).  Students will use a 2 cm segment and mark whether or
not one of the 4 species of lichen is present and whether or not
another unidentifiable species is present.  The transects will be
limited to about 4 cm in height, and if a species is present on the
tree but not in one of the two belts they can note that in there
field books.  The students will have GPS units available so they can
log tree coordinates and start their transects on the south side of
the tree.

   The data will be processed by determining a percent coverage for
each species and an overall percent coverage.  The data is obtained
such that we can make some observations about height variability as
well as which side of the tree lichen prefers.  The primary project
for the students this summer is to map all of the trees on campus,
so they will have tree age, species, height and canopy dimensions
available to them as well.  This should give us some indication as
to whether the belt transects provide sufficient data for a more
city-wide study.

   I would like to generate an index of atmospheric purity from this
data, however I have no IAP numbers for lichen species in this
area.  If some readers are familiar with numbers, or could give me
some reasonable estimates, we could at least demonstrate to the
students how this number is calculated.

   Any comments, suggestions or, "how can I get involved" questions
will be entertained, and I will most definitely post any interesting
results to the group.

   Thanks for reading.

Dear Chicago Lichens Group:

I am planning a two day overnight trip to Alden in McHenry County,
Illinois over the October 14-15 weekend at the Small Waters
Gathering Center. I need at least six people to make this happen, so
hopefully I am writing early enough for everyone to consider this
trip.

My plan is to meet at Small Waters Gathering Center and use it as a
jumping off point for exploration in McHenry County.  A rough idea
of the event would be to botanize most of the day in the field, but
in the evening use the facilities there as a lab where we will look
closer at lichens under microscopes.  I'll have keys and papers and
guide books to help along the way.

We'll spend the night there and in the morning botanize again and
probably finish off identifying lichens back at Small Waters.

I'll work out more prercise details later.  (If you can't spend the
night there, then please consider our Saturday and/or Sunday hikes
in the daytime.)

Please read the following from Judy Speer at Small Waters Gathering
Center.  It explains the costs and rooming information.

"Rich:
OK, we have Oct. 14-15 reserved for you.  We'd like 6 people
minimum.    Arrival and departure times are flexible.  We can work
it out
according to your schedule. We ask for (per person) $10 for 1/2 day,
$20
for a full day, plus $15 overnight lodging.  So, for example, if you
decided to come here  around 1 pm Saturday and stay until around 1
pm
Sunday, it would be $35 per person.  Lodging is dorm style, with 2
to 4
people to a room.  You may bring your own food, or we can provide
supper
Saturday evening ($10 per person) and/or breakfast Sunday morning
($5 per
person).  Our food is vegetarian, healthy, and mostly organic.
We're looking forward to hosting your group, and maybe learning a
bit about
lichens ourselves.

Directions: 15820 IL Route 173.  1/2 mile east of Alden Rd., 4 1/2
miles west of Route 47.  For more information call Jack and Judy
Speer at (815) 648-1372 or (815) 690-6240.
Judy"


Please consider attending this first of a kind foray/overnighter for
the Chicagoland Lichenological Society!

Rich Hyerczyk

I just uploaded some new photos to my JPDenk photo album from my
recent trip to Kentucky. The new photos are DSC5840 and 5841, Cladonia
coniocraea, and a Cladina (if I'm remembering Rich's ID that he did
for me), P1010737.

The Cladonias were photographed near the Furnace Ruins, Irvine, KY
(right by some interesting club mosses, seen in the background) and
the Cladina was photographed in the Red River Gorge area on the edge
of a cliff. Both areas are in the Daniel Boone National Forest, a
spectacular area for anyone interested in natural history of any variety.

Send instant messages to your online friends http://uk.messenger.yahoo.com

(This was sent to me from Doug Greene from the LICHEN CLASS group.

I am forwarding it to Chicago members.

To all who are interested. Clifford Wetmore has placed the
Keys to the Minnesota Lichens in a dowloadable PDF format.
http://www.tc.umn.edu/~wetmore/Herbarium/HERBHOME.htm

It's the latest updated version 2005.

These keys should be good for most of the North Central and even
Northeastern USA and the adjacent parts of Southern Canada.

Just a reminder that the Chicago Lichenological Society will be
looking for the lichen flora at Corron Farm in Kane County on Sunday
April 30 from 10 am to 2 pm (or longer is interest is there)

Rich

Rich,

   I "developed" a field experience for high-school students that had them
estimate lichen density on trees at the CSU campus.  Students were given
transparency paper and were told to identify which side of the tree was most
abundant in lichen (kept it to N, S, W, and E for simplicity).  I also
limited them to the base of the tree, so that there was some consistency
among the four groups of five students performing the experiment.  Then they
traced the lichen onto the transparency.  Once these data were collected,
they attached a piece of graph paper to the transparency and estimated
lichen density by counting squares.

   The problem with this method is that it doesn't take into consideration
the smoothness of the bark.  Since CSU has an abundance of cottonwood, this
would be a serious problem for "research-grade" data, however for the
students, not accounting for the roughness of the bark was a systematic
error (since all measured lichen density on the same type of tree) that
didn't seriously influence our analysis.

   I think the students did enjoy it, and some of the more engaged students
were interested in how to deal with bark roughness, so I found this field
experience successful.

Would anyone have any information on lichen studies for students in
ecology courses?  I want to offer some kind of lichen study as part of
an ecology course.

I have seen some studies where students put tracing paper over lichen
covered tombstones and estimated coverage...it was on the web, but I
can't find it now.

Or any work on setting up transects to measure lichen diversity?

If someone could direct me to a web site showing how to do studies of
lichens I would appreciate it.

Thank-you.

Greetings:

On Sunday April 30 I will be leading a lichen search at Corron
Farm.  The location is in Kane County, IL.  It will run from 10:00
until 2:00 (or longer if we decide to stay).  Last summer we were
there on a day when the temperature was 100+ degrees, but in April
it should be a bit cooler.

Corron Farm is 7N761 Corron Road, St Charles

Take Randall Road to Silver Glen Road. West on Silver Glen about 4
miles to Corron Road. North on Corron Road to farmstead on the right.

for more info:
www.kcchronicle.com/MainSection/local/295346289267062.php

Corron Farm has granitic erratics, wood fencing and many large, old
Qaks.

Please let me know if you're going.  Bring lunch, water, HAND LENS,
and otherwise dress for the weather.
There is no charge.

Rich Hyerczyk


I'll post a species list from the July trip tomorrow.

Subject: [chicagolichens] lichen distributions

    Rich recently initiated some good discussion of native versus non-native lichens.  The thing to keep in mind about lichens is that they are the perfect pioneer species.  For example--In 1967 the completely new volcanic island called Surtsey was formed somewhat near Iceland.  It took some time to cool off, but by 1970 there were already lichen species on it!!  Would those then be considered non-native?  Of course not--there was nothing else there at that time but some algae.

    In the list of lichens that Rich found in Chicago, there were 5 species found only in North America.  Caloplaca suboluta, Physciella chloantha, Physconia leucoleiptes, Xanthomendoza fallax, Xanthomendoza fulva are these.  That doesn't mean they're not found elsewhere, that's just what the records seem to indicate.  Physconia leucoleiptes has an occurence showing up in Estonia, but that is a specimen in a collection and could've been collected from America. 

    Anyhow, below are some good links to look up lichen distributions. 

http://www.ies.wisc.edu/nplichen/  US National Park distributions ---quite a good listing and easy to look up

This next one below has actual diagrams of the various species distributions (not North American)

http://geobot.botanik.uni-greifswald.de/sammlungen/flechten/karten/album/slides/

 The one below has a worldwide distributions list.  To advance on to the next page, type a 2 or 3 at the end of the address.

Have some fun with these links,

Tim

The reason I had asked for information about native vs alien lichens
is that "bob the chemist" wants to do a study about lichens and air
pollution.

See message #83
AND
section "3"

of his message.

Thanks!
