Observation 68957: Conocybe Fay.

When: 2011-06-10

Collection location: Bolinas Ridge, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These were growing in the woods on Doug fir debris.
The caps were up to 1.7 cm across and stipe up to ~ 8 cm long.
The spore print was rusty-brown and spores measured ~ 13.2-16.0 X 6.9-9.0 microns with a large apical pore and a small nipple on the opposite end.
Could not find any Cheilocystidia.
I suppose Conocybe tenera is a possibility but the habitat seems wrong and the spores are somewhat larger than usually reported.

These didn’t hold up to well so I didn’t save them. Maybe next time I’ll go the extra mile but I’ll need more inspiration.

Spore size is usually a good character in Conocybe. But to really get enough info to the species, you need to the caulocystidia on the upper stipe. Also the size of the capitulum (the ball on the end of the cheilocystidia) is used, and are the basidia 2- or 4-spored. Presence of pileocystidia can also help, but that doesn’t really get to the species or not, it is just extra info.
