Observation 172980: Pluteus granularis Peck

When: 2014-08-04

Collection location: Akademgorodok, Novosibirsk, Russia [Click for map]

Who: Tatiana Bulyonkova (ressaure)

No specimen available

Notes:
At first I thought this was a Pluteus umbrosus, but it differs larger size, more pronounced reticulate pattern on the pileus (and at the same time the pileus is less fuzzy and more minutely velvety), smoother stipe (it’s powdered with blackish floccules, not fuzzy all over) and absolutely colorless pleuro- and cheilocystidia. The terminal elements of the pileipellis and stipitipellis are also slightly different from those of the typical P. umbrosus: they are shorter, wider and more distinctly fusiform.
I collected it in two locations this year and the difference with P. umbrosus is very clear.
I’m marking my id as “possible” because to my knowledge P. granularis hasn’t been documented in Europe/Russia.
