Observation 24973: Entoloma subgenus Claudopus (Gillet) Noordel.

When: 2009-07-28

Collection location: Boone Co., Missouri, USA [Click for map]

Who: MOFunGuy (jrapp)

No specimen available

I’m not sure as the exact ID, but pretty confident this is a Crepidotus based on the pinkish brown spore color. There are not very many creps in field guides, so I decided to spend the evening with with two distinguished authorities (Hesler & Smith 1965). As a result, I believe this Crep comes closest to the species haustellaris which is described as having a cap which is “dry matted-fibrillose pinkish buff to grayish color”, gills which are “broad becoming cinnamon brown” with a small stem, size of 4-10 (15) mm. It is described from Michigan in July-August in hardwoods.

I’m interested to see if others are familiar with C. haustellaris or a mushroom like this one pictured.

Gerhard – I got lucky with the Crepidotus cinnabarinus, so maybe with this one too?

This does have a stem, though it’s not much of one, and the gills run down it. It is best seen in the picture from underneath. I’ll see if I can post a closeup.

I was able to find a few examples of Entoloma byssisedum – from Europe (France, Sweden) and that does appear to be a gray, somewhat hairy, pink-spored crep-like mushroom. That’s the closest yet.

Does it really have a stem?

If not, I think this is the stemless member of the Rhodophyllaceae, in the genus Claudopus. The only species I know is Claudopus nidulans, and this loks like that.
