Observation 59588: Cladonia grayi G. Merr. ex Sandst.

When: 2010-11-07

Collection location: Dabney Creek, Madison Co., Arkansas, USA [Click for map]

Who: Jason Hollinger (jason)

Specimen available

Notes:
abundant on sandstone outcrops

These large colonies were invariably apodetiate, forcing me to guess. Surprisingly, it actually keys out in the apodetiate group under Cladonia in the Harris & Ladd keys. To be sure I would presumably need to verify the presence of grayanic acid via TLC.
