Observation 65022: Gymnopus iocephalus (Berk. & M.A. Curtis) Halling
When: 2010-08-15
No herbarium specimen

Notes: I initially thought this was more purple and the cap less striate than M. pura, but having seen it on the west coast, and noting the range of photos identified as M. pura on MO, I am willing to take the chance. Note the last two photos where you can see decomposed caps – these do look striate.

Recognized by sight

Recognized by sight: something near this, anyways. Looks like it has a finely pubescent stipe, a tougher consistency, and like you said, less striate. Note: the first couple images on Google Image Search are actually of Prunulus purus group

all one has to do to see pages of a particular species is type that name into the search engine. works for all of ’em!

thanks for your careful reading, Andrew.

one of my favorites when I was collecting back east. Here’s a whole page of them from MO:

you are right tho, Prunulus or Mycena pura can fool you with lots of different forms, and they ARE purplish, too…

also called Collybia iocephalus, Marasmius iocephalis, Purple Coincap

References to Collybia iocephalis in Arora MD p202; Peterson FG p147 Pl. 17; Audubon FG p755 #106 … and I am ordering the SE guide!

It is in the Audubon and Peterson guides and it is in the key in Bessette and Fisher’s Northeastern mushroom book. A nice photo and description is in Bessette & Roody’s Southeastern guide.

Thanks Christian and Walt

That is not in any of my books, but the other species of Gymnopus do share characteristics. Index Fungorum lists Gymnopus iocephalus as Marasmiaceae. What’s with that? …and earlier it was a Collybia. Very interesting. Thanks again.
