Observation 139462: Clitopilus (Fr. ex Rabenh.) P. Kumm.

0 Sequences

Crepidotus seems wrong, but perhaps an atypical species (couldn’t find good references for other ideas) – growing from ground/ with mosses (NOT from wood) and seems to have a short stem (not stemless)

Found in West Block off ecotour road
Habitat among moss and lichens on ground in somewhat sparse and short vegetated grassland
Apparently somewhat common (but easy to overlook)
Seems to like growing out of sides of the ground in bison hoof-prints (shelving growth forms) but also sometimes straight out of the flat moss (with stem still off-center/ cap unevenly shaped)
Tiny (less than 1cm wide) and often several together
Hard to get spore print (perhaps try gills under microscope later)

Sept 7 microscopy:
odour when wetted and crushed very raw (raw vegetable)
swelled up considerably after wetting
spores very abundant (unlike other specimens working with)
see pics (all 15 × 40 – highest objective I have on my old microscope)

May 1, 2014 microscopy:
I tried again but I think my collections just don’t have spores on the gills (immature? or too old and all gone?). However, I looked at the little fruiting bodies themselves, and the gills definitely have a bit of a pinkish tinge to them, in contrast to the rest of the fb. It’s not apparent in the pictures here and I couldn’t get any better specimen pics at the time. Perhaps I’ll get out my Nikon and micro lens later. Thinking back to a suggestion from Dr. Thorn, Clitopilus seems like an excellent fit. Spores would help confirm, but they’re hard to find (not sure if my earlier “spores” pic is spores or just other bits of things). There may be potential for DNA analysis in the future.

Upturned ground with fruiting bodies, note gill pattern and stems, white all around
Top view among moss, growing like tiny shelves from ground
spores closer
abundance of spores
stringy (strands of hyphae?)
this is how they grew, from the sides of soil, very tiny and inconspicuous
