Observation 4844: Gomphidius Fr.

When: 2007-11-11

Collection location: Howarth Park, Santa Rosa, Sonoma Co., California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

Base of stalk only faintly yellow. Fruiting under Douglas fir.
11/12/07: Today I dug a bit around the base of the stalk and found it to be a much brighter yellow. I think I remember, from last year, that the bright yellow would be buried—-is that right? Or would I expect to see bright yellow prior to digging up the specimen?
It would appear that the only way to conclusively call this either G. oregonensis or G. glutinosis would be with a view of the spores. Although G. oregonensis often grows in clumps, Mykoweb states that it doesn’t always.

One species to consider is Gomphidius smithii, which has little or no yellow at the base.
