When: 2009-11-07

Collection location: Salt Point State Park, Sonoma Co., California, USA [Click for map]

Who: Douglas Smith (douglas)

Specimen available

These are hygrophanous, and viscid. I’m not sure I’ve seen C. mollis as hygrophanous before, although it needs to be viscid. I need to get these under the scope at some point.

Adding some micro-details:

The first micro-shot is of gill and cap material in Meltzer’s at 400×. I had grabbed a gill here to look at spores, but some surface material came along, and here is the textured surface hyphae distinctive to this species. Also it is lacking clamp connections.

The second micro-shot is of spores from the gill at 1000x in Meltzer’s. Here the spores are ellipsoid and smooth, many are slightly pointed. Ave spore : length – 8.59 +/- 0.62 (err 0.16) um, width – 5.82 +/- 0.30 um (err: 0.09) – q : 1.48 +/- 0.09, on 16 spores.

This is rather distinctive to C. mollis, and agrees well with the "Crepidotus of North America of Hesler and Smith. But in a new work on Creps. “Il genere Crepidotus in Europa” this agrees even better with C. calolepis var. squamulosus. Which they have as a Crep. found in the Mediterranean, so it might be a stretch to have this as found on the California coast. So, if there is any argument, well you can have it either way.
