Observation 50140: Leptogium cyanescens (Rabenh.) Körber

When: 2010-05-08

Collection location: Turnipseed Preserve, Wake Co., North Carolina, USA [Click for map]

Who: Gary Perlmutter (gbperlmutter)

Specimen available

Notes:
This keys to L. cyanescens except for the color. Lobes smooth, isidiate. An alternative is L. millegranum, but I’m not comfortable with that name either. Any help would be appreciated. I can also send specimens upon request. This cyanolichen is common in shaded forests both on rock and bark.

I would have the same exact problem with this thing. I have a photo of something just like it from the Smokies. I also ended up calling it L. cyanescens not having any better names. However, I also have “proper” bluish-gray cyanescens (more common) from Nantahala Gorge and several places in the Smokies. Could yours possibly be a Collema? Like an extraordinarily well-developed Collema subflaccidum… with flattened isidia… hmmm… Maybe not. :)
