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

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. :)
