Observation 45989: Russula Pers.

When: 2009-10-26

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

Who: Bob Zuberbuhler (Bob Z)

No specimen available

This medium size mushroom was found in a hardwood forest. The cap was 4" across and was bowl-shaped. The margin was upturned, exposing white gills. In one area the upturned edge seemed to have split into two gill layers. The cap top was brown, much darker toward the center. The white gills were narrow, crowded and ran down the stalk. The stalk was white, 7/8" thick and 4" tall.

This seemed too large to be “ordinary” I. gibba, but the maximus variety is supposed to be found only in the Pacific Northwest. Any ideas?

it takes time to know what features are important in ID, and which are variable…

and those darned mushrooms look different as they age and individuals look different even within species! Many mushrooms will show an upturned cap like a clitocybe when they age, at which point they can kinda resemble decurrent gills to the untrained eye. And old russula stems won’t snap! if they are bug-ridden or rotten (both states fairly likely in older forms). Experience is your best guide…and when you make a tentative ID, try and look at other examples of the mushroom that you think it might be. no harm in making an off-the-wall guess, unless of course you plan on eating it!

this is pretty obviously a russula tho…the general “gestalt” of which you too will recognize after a few years of IDs under your belt.

The gills in this observation are broadly attached, but nowhere near decurrent (running down the stipe).

Also, the texture of this mushroom should have been chalky (breaking cleanly) or somewhat fragile/brittle, not fibrous or rubbery at all, as in Infundibulicybe
