Observation 18276: Lichen P. Micheli

When: 2009-02-05

Collection location: Sewanee, Franklin Co., Tennessee, USA [Click for map]

Who: Chris Parrish (kitparrish)

No specimen available


Location: 35°12’36.32"N, 85°55’53.79"W, el. 574 m. Lake Cheston.

Growing within 2 m of the ground on the trunk of a large tulip-poplar, Liriodendron tulipifera, on a park-like grassy slope at the shore of a small lake.

In actual size, this little patch of lichens was somewhat larger than a postage stamp.

Note added on 07 Mar 2009: Jason, this was my “Eureka” moment, when I first discovered microlichens. They were on a fragment of bark with a much larger lichen which I was sliding around under the microscope, and all of a sudden … Yikes! … There’s a whole world down there at about 5% normal size!

Haha, there are at least 5 species here by my count! I did a study of a newly-fallen tulip poplar on the “other side” of the mtns a year or so ago, and was blown away with how many species of crust you could find in a square inch. I was trying to count number of species and area covered by each for about a dozen 2-foot sections cut at regular intervals. Ohmygod, what a tedious job!!
