Observation 84335: Leptonia decolorans (E. Horak) Largent

When: 2011-12-02

Collection location: Samuel P. Taylor State Park, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

Notes:
These were growing in mostly Redwood humus.
I’m tentatively going with the Leptonia decolorans rather than Leptonia parva because the cap color remains blackish blue even with aging and drying conditions. Also because the spores seem more angular than shown for L. parva as well as what I believe is some Cheilocystidia that I found, although it didn’t seem to be overly abundant.
Spores were ~ 9.3-11.0 X 7.4-8.1(9.0) microns.
These were picked and left for the MSSF Fair displays. I didn’t see them Id’d and only had a piece of gill to work with so there is no material left to work with.
