Observation 202123: Rhodophana nitellina (Fr.) Papetti
When: 2015-03-30
0 Sequences

Growing on the ground, possibly on buried wood or woody debris, in mixed woods.
Caps up to 3 cm across. Whitish particulates on cap probably from environment as most of what I found had the same material on caps.
Cap somewhat radially appressed fibrillose.
Odor fairly strong, perhaps fruity.
Spore print thin but colored, light orangy. Spores not amyloid or dextrinoid.
Spores ~ 7.4-9.5 X 4.0-5.2 microns, elongate lacrymoid, and sl bumpy.
Did not see any gill cystidia.
Initially thought they might be Gymnopus nivalis but stem is too tapered and odor and spores not quite right.

Rhodophana lacks cystidia

No cystidia?

should have abundant cystidia, kind of sharp and thick-walled if I remember correctly

funny, the name changed from Tricholomopsis while I writing the above. I withdraw the cystidia prediction.

I think so too….

Now, how many species going by this name in CA? that remains to be seen.

a print would even help here.

not quite.

As I said in my notes

the whitish particulates on the cap seemed to come from some kind of pollen or other environmental contaminant as everything I was finding had the same material on them.
There is also a description on Mykoweb. Everything pretty much fits, at least for what we have been calling these on the west coast.

glabrous pileus…??

i didnt write the desctiption, nor do i live in cali and i have also never seen the species…

but, that is what the description for Rhodophana nitellina says…

just sayin’. ;)

if Noah has some other information to share…that’d be cool.

I think Noah is correct.

They match the notes in Dennis Desjardin’s “Spring Fungi of the Sierra Nevada” and Dimitar’s notes in Mushroom Hobby.
