nice when the DNA confirms what you already knew.

The pictures do not show Hypholoma marginatum

Mr. Rockefeller,
can you explain, why you think it is H. marginatum and not a Psilcybe?
Greetings

striate margin
By: Gerhard_S
2017-01-08 01:18:36 PST (-0800)

Why do you think that this is an Hypholoma? And why not an Psilocybe? It looks more like P. pelliculosa or P. mexicana than H. marginatum. Please, can you explain?

Ludwig, E. (2001): “… Genus Hypholoma… predominantly not hygrophanus, margin striate only as an exception…” “Hypholoma marginatum: … margin not striate…”
The only europaen Hypholoma with claerly striate margin is H. ericaeoides. Also the margin of. H. elongatum somtimes is slightly striate when moist (Ludwig 2001).

really?

no description for H. marginatum, a European sp. also found in the PNW, shows such a striate cap. I suspect this is something different, altho it could be a Hypholoma of some kind.

Here is an obsie of H. marginatum by J. Frank:

Look Ma! No striations! Trudell’s Mushrooms of the PNW also shows a non-striate cap.

Hypholoma like this one should.

Edit: I changed my mind.

striate and transculent margin?
By: Gerhard_S
2017-01-06 04:30:24 PST (-0800)

I’m wondering. Hypholoma should not have a striata and/or transculent margin.
