Observation 90297: Agrocybe praecox group

When: 2012-03-17

Collection location: San Rafael, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

These were growing in a median on the ground with a lot of woody debris.
Both specimens had lots of rhizomorphs at the base of the stipe.
The larger cap was 7.3 cm across and its stipe was ~ 9 cm long X 2.6 cm wide.
The brown spores were ~ 8.0-9.3 X 5.0-6.4 microns with a small germ pore.
Gill cystidia was not too plentiful but what I found was rather variable, so I included photos of some typical forms.
These appear to be the darker, more robust form of Agrocybe praecox that Arora mentions in MD.
