My only info on the species is from Brodo, Sharnoff & Sharnoff 2001:

Primary squamules finely divided, not sorediate. Podetia gray-green, without cups but often fertile with light brown apothecia, usually slender and hardly branched, 5-20 mm tal, more or less covered with small squamules (or sometimes microsquamules that resemble granules); the area between the squamules either has an intact cortex or is predominantly naked and translucent. Chemistry: PD+ yellow, K-, KC-, C- (baeomycesic and squamatic acids). Habitat: on rotting wood, logs, and stumps, rarely soil. Notes: Resembles C. squamosa but is PD+ yellow, K-.

Good suggestion.

Indeed, the micro-squamules (as you call them) of these specimens are much alike to those of C. beaumontii, a photo of which I saw in Sharnoff site. For further reference
do you know what should be the result for the chemical tests (K, C and KC) for C. beaumontii ? I’ll try to perform these test, if I can find these specimens again.

C. squamosa has well-developed squamules on the stems. These micro-squamulose things remind me more of something like C. beaumontii although I’ve never seen one in the wild.
