Panaeolus alcis

Girinukas, can you correct the name? Thanks.

Very pretty.

Wikipedia is far from an complete source of information on Panaeolus unfortunately. P. papilionaceus is cosmopolitan, here is some more info from Gerhardt's Panaeolus monograph.

"Verbreitung:
Kosmopolicisch, fast iiberall die haufigste Panaeofus-
Art. Europa: Deutsch land, Belgien, Danemark, Fzr5crs,
Finnland, Frankreich, Gronland, Gro6britannien, GUS,
ltalicn, Jugoslawien, Niederlande, Norwegcn, Ostcr-
reich, Schweden, Schwciz, Spanicn, Tschechien/Siowakei,

silien, Kanada, Kolumbicn, Kuba, Puerto Rico, Uruguay,

na."

and for var. parvisporus with an fugaceous veil (Disappearing quickly):

"\'erbreitung:
Anschcinend nahezu kosmopolitisch, docb vie! seltener
als die var. papilionaceus. Europa: Deutschland; Afrika:

Australien: New South Wales."

I'm unfortunately missing the pages with the P. alcis (= P. alcidis) description, but here is what is included in his world key:

"5 Spores (cross-section) very little flattened, slender (fig.
2d); small, not hygrophanous species on droppings of
elk and reindeer.........................Panaeolus alcidis (19)"

and his European key:
"12 Spores (cross-section) little flattened, slender; small,
not hygrophanous species on droppings of elk and
reindeer .................................... Panaeolus aleidis (19)"

Stamets doesn't really cover the species in his 'Psilocybin Mushroom of the World' book, but he briefly mentions that its known from Scandinavia and Canada. The range is probably wider than that.

Thanks, but Wiki says we have only those in Lithuania: http://lt.wikipedia.org/wiki/M%C4%97%C5%...

This is probably not P. papilionaceus (= P. sphinctrinus), that is a larger species with an appendiculate cap margin. I think P. alcis looks promising, but ofc for a confident identification microscopy is probably needed. :)

Please collect, dry, label, and save specimens next time.
