Observation 25981: Lichen P. Micheli
When: 2009-09-29
No herbarium specimen

Notes: Will spend some time with this rather pretty coral-colored lichen shortly. Has odd attachment to 1" diameter branch it was growing on: meandering black snake-like holdfasts instead of the rhizimes I expected to find. Cortex white, thallus sometimes cracking, but typically growing from a centralized point and radiating outward. Green algae growing on bottom-most portion of branch, then this lichen, then what looks like Parmela sulcata on the upper-most surface. Where this coral-colored lichen and the Parmela meet, they push each-other outward and upward. Small raised ridges and pimple-like areas on surface of thallus.

to document some of the other mushrooms coming out, and couldn’t find my branch with the cool pinkish thingies. One of the problems in collecting at a doctors office: groundskeepers are too clean.

doesn’t look like a lichen to me

I agree with the Parmelia sulcata, and the algae at the base could well be a crustose lichen, but the tan/buff/coral thing looks much more like a basidio to me. At any rate, doesn’t look like any lichen I’ve ever seen. (Heh, maybe you’ve discovered a totally new basidiolichen! :)
