Observation 47506: Psathyrella (Fr.) Quél.

When: 2010-06-22

Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

No specimen available

I believe this mushroom is the same type as seen in obs 47013.
Although Psathyrella seems likely, I wonder if this could possibly be Panaeolina foenisecii. There were P. foenisecii scattered about the lawn maybe 10-15 feet away from where this one and the ones seen in 47013 were found. This spot is a grassy area adjacent to a compost heap. The flesh in the cap is more substantial than generally seen in the flimsy/crumbly foensecii. Stipe in this obs is not as durable as in 47013; fairly fragile when the mushroom was harvested (base easily broke off). Large spores point toward Psathyrella… but P. foensecii also has large spores. Spore print is very dark puple brown… the same color as for foensecii.

Some field guides state that P. foensecii has (had?) been placed into Psathyrella. I wonder why it isn’t?

Dried specimen available for study.
