Observation 280023: Agrocybe sensu lato

When: 2017-06-25

Collection location: Stokes State Forest at Lake Ocquittunk, New Jersey, USA [Click for map]

Who: I. G. Safonov (IGSafonov)

No specimen available

Collected during NJMA Foray by unknown participant(s). The collection was taken by J. & N. Burghardt for a further study.

Description by J. Nina Burghardt (observed and recorded a few hours post foray?):
“Cap: 3 cm wide, grayish-brown with darker fibrils at inrolled edge. Gills coffee-brown (at maturity – IGS), attached. Membranous veil attached and covering the gills. Stipe 6 cm long and 0.5 cm wide, silky-fibrous and cottony-white at base lodged in rotted wood. Spores 7.8 × 5 microns with an apical pore.”

To this I would like to add – from memory and looking at the pix taken during the ID session when the mushrooms were still fresh – that (a) the caps are glabrous, not sticky or viscid, and somewhat hygrophanous, with a corrugated/pitted pileipellis on the outer region of disk, and not bearing any visible scales or fibrils, (b) the gills are whitish-gray from start, © the veil is cottony-filamentous-fibrous and (d) the stipes are whitish above and grayish-brown below and streaked with longitudinal lines and ridges.
Nina thinks this could be Pholiota lenta.
