Observation 50612: Crepidotus mollis (Schaeff.) Staude

When: 2010-08-09

Collection location: Lainzer Tiergarten, Wien, Austria [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Under mixed hardwood forests, mostly oak and beech.

Cap surface is viscid, rubbery and sticky really.

Adding some micro-details:

The first micro-shot is of the gill edge at 400x in KOH. There are thick long cylindral cheilocystidia on a non-fertile surface. There were no pleurocystidia obs.

The second micro-shot is of the cap surface at 400x in KOH. This is a bad photo, but you can see some partially pigmented hyphae with mostly non-pigmented hyphae. There are also some thick texture hyphae here, but they are hard to see. I should re-do this mount to show the feature that I wanted to see, but at least I could see it.

The third micro-shot is of the spores from the gill at 1000x in KOH. The spores are ellipsoid, somewhat pointed, and smooth, with no germ pore. The apr. size is 9 × 5 um.

These are clearly C. mollis, and this is the original form, the one agreed upon by all authors as to what C. mollis should look like (after reading many sources to come to this conclusion…). The forms with pigmented hyphae, that can even become shaggy people disagree on, if they are just other forms of C. mollis or C. calopis, and other variations.

But yeah! I found the real C. mollis now. At first walking by I dismissed these as another Pleurotus, there were plenty there where I was, until I turned one over. With the viscid cap, it gives them a rubbery texture, and they were similar to oysters from a distance.
