Growing on wood chips, mostly likely of Bishop pine. Caps up to 5.5 cm across surface and slightly tacky. In young fbs, the veil is like a thin solid film, with much of it remaining on the cap edge. Got a weak spore print, brownish. Spores ~ 6.8-8.1 X 5.1-6.1 microns, ellipsoid, smooth and appearing not to have a germ pore. Gill cystidia present, mostly utriform but most with a subtle double neck. They don't look familiar to me(?).
