i think this is more a Simocybe than a Crepidotus

Anyway , i cite “THE CREPIDOTACEAE (BASIDIOMYCOTA, AGARICALES):
PHYLOGENY AND TAXONOMY OF THE GENERA AND
REVISION OF THE FAMILY BASED ON
MOLECULAR EVIDENCE”:
“Chiefly, Simocybe can be diagnosed
from Crepidotus by (1) basidiospores which are always
smooth and differ from smooth-spored Crepidotus species
in that the adaxial side is typically applanate to depressed;
and (2) abundant pileo-, caulo-, and cheilocystidia (the latter
two most typically subcapitate), lending a pruinose appearance
to these structures macroscopically. Additionally, many Simocybe
members have an olivaceous tint to the pileus, lacking
in Crepidotus.”

Spores are smooth?

there is much talk of stipitateness (stipitation? stipitacity?) in Cathy Aime’s thesis on the genus:

since this is stipitate, I do not think it can be a Crepidotus.

No, it wasn’t sessile, all of the specimens were attached by a stipe.

was exclusively sesile?

Ioana – this is a great post, someone will probably recognize this from the images.
