Collection location: Cibola National Forest, New Mexico, USA [Click for map]

Who: Jason Hollinger (jason)

Specimen available

On sandy soil. There are very few yellow C- Acarospora on soil according to Knudsen in the Sonoran Flora Vol III:

A. schleicheri — imbricate-squamulose
A. rhabarbarina — never stipitate or subsquamulose, disks dark red-brown
A. socialis — becoming stipitate and subsquamulose, disks red-brown or not

It sure doesn’t look the same as the saxicolous specimens of A. socialis growing nearby, but it doesn’t match A. rhabarbarina either (continuous algal layer and has some lower cortex near the margins implying that it’s becoming subsquamulose.
