Ponieważ dostałem e-mailową zgodę od Nicolas Van Vooren'a na umieszczenie na "bio-forum.pl" jego klucza do Otidea sp. - uchówka, więc zamieszczam.
Nigdy nie wiadomo, co będzie miało krótszy żywot w sieci; "ascofrance.com" czy "bio-forum.pl" ;-)

The microscopic features of the original description let us think that it isn’t an Otidea.

This taxon was interpreted in various ways during the past time. The most collections identified under this
name have to be related to
O. umbrina s.l. or
O. bufonia.
Otidea violacea A. L. Smith & Ramsbottom,
Trans. Br. mycol. Soc., 5, p. 237 (1916).
The type has been revised in 1932 by Nannfeldt; it’s a
Peziza species.
