Observation 26132: Mycena (Pers.) Roussel

When: 2009-09-20

Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These were were rather smallish, saprophytic species that seems to have maximized the technique for a gilled mushroom to disperse spores. Not satisfied with merely upturning, these essentially turn themselves inside out to form an oval with gills facing in all directions.
The few spores I was able to obtain appeared white and non amyloid. I’ve included a couple of micro spore photos because they were so sparse that I wasn’t sure if they were actually spores. They were also rather large, in the 17 X 12 micron range.
Can’t find anything that looks like them but they do have a Mycena-like appearance. Wonder if anybody has any ideas?

the gills were “free”, as one might expect when they are turned out like that.
The spore photos were in Melzers and I didn’t get enough to drop to see a true color, but they were probably whitish. They are not very dark in Melzers, so that probably rules out Mycena pura, as does their large size.

do you have a picture of the gill attachment?
also, what color were the spores??
it is hard to make out from the micro photos.

I voted against Mycena pura because

This is growing from wood, not on the ground in the pine duff.
