No collection date for Illinois find of H.livida

I wonder if the Illinois find is a part of the trend of retreating northern species and advancement of southern species as part of the warming trend. From the insect field, every year there are finds in Wisconsin of insects normally associated with Missouri or areas around there. As winters get warmer, they come and establish themselves here, lack of deep frost allowing them to safely overwinter. Of course, lichen move much slower than insects…
On the other hand, the location of this specimen is deep in the driftless portion of WI, roughly in the mid-section of the state, characterized by steep hills and deep valleys.

Would you look at that!

Didn’t think to check. Yes, my research claims the northern border for Hypotrachyna livida is Texas, Arkansas, Illinois, Maryland, eastern Pennsylvania, southern New England coast.

Good thing you aren’t keeping track of all the times you’ve proven me wrong!

CNALH locality maps can give an idea of what to expect. In this case, records for Myelochroa galbina flood the zone in WI. Virtually all of the records for Hypotrachyna livida are from MO, the SE, and the eastern seaboard, but Culberson identified a specimen from near Elgin, NW of Chicago in IL.

Most of the time, being an amateur, I name specimens only if somebody else identifies them for me, although there are occasions when I feel bold and try to do it myself (usually with dire consequences :-). This one was IDd as M.galbina, I believe. And H.livida has not been found in WI (yet), to the best of my knowledge.

Have you ruled out Hypotrachyna livida?

I can’t tell for sure from the photos.
