Observation 98632: Ganoderma P. Karst.

When: 2011-08-27

Collection location: Madera Canyon, Santa Rita Mountains, Pima Co., Arizona, USA [Click for map]

2m

Who: Minh Nhân (Iván Rodríguez)

No specimen available

Notes:
Found this collection of bracket fungus on a fallen tree away from a popular hiking trail. I could not get clear shots due to my camera’s fear of shady environments. The fungi were firmly attached to the fallen tree, and they do not seem to resemble Ganoderma tsugae which I initially suspected, but that’s up to discussion.
