When: 2011-09-16

Collection location: Wrights Lake Rd., El Dorado Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Caps up to 4.1 cm across.
Did not get any real milk from the gills.
Spore print was whitish and taste was mild.
Spores were ~ 6.9-8.5 X 5.8-7.0 microns. They had fairly prominent warts and some reticulum.
The Bessette book doesn’t have any photos of this species but the description seems to match pretty close although I didn’t get any discernible latex from the gills.
They were growing in what I would call “…in seepage areas in montane conifer forests…” at ~ 7000ft.
While they were listed as “common”, I don’t see any other sightings in the usual places so my confidence level for the ID is minimal.
