Observation 22287: Gerronema strombodes (Berk. & Mont.) Singer

When: 2009-06-17

Collection location: Silver Spring, Montgomery Co., Maryland, USA [Click for map]

Who: John S. Harper (jsharper)

No specimen available

Found on down trunk at 2 locations in wooded area. Type of wood unknown. Could not get a spore print. Looked like a chanterelle to me, but I thought they only grow on the ground, not from dead wood.

With the helpful comment of Andreas, and a bit of computer research, I believe Chrysomphalina was a good suggestion on genus, but apparently subject to a name update. MushroomExpert.com comments: Chrysomphalina strombodes is a former name, as are Omphalia strombodes and Clitocybe strombodes. http://www.mushroomexpert.com/gerronema_strombodes.html See also Roger’s Mushrooms at http://www.rogersmushrooms.com/.... (The descriptions makes me feel not quite so incompetent in not being able to even make good guess last night after looking through my texts.)

My specimen did not look like few images of C. chrysophylla that I found on the internet – the pileus was flatter, rather than convex, and the lamellae more strongly decurrent.

It did look like C. grossula pictured at:
http://www.fs.fed.us/pnw/pubs/gtr572/partb2.pdf, but the wrong side of the continent.


Note pileus not funnel shaped, but having flat pileus

may be Ch. strombodes or chrysophylla. May be those species have recieved a new generic name. I seem to remember in the back corners of my brain that REDHEAD published something concerning this genus.
