Hi all,  I would like an opinion on whether this

Durella connivens ?
Carmel Sammut, 13-01-2016 21:53
Small black disc shaped asco on dead branch (?broadleaf)
Spores 6-9 septate, 30-50µm x 6.4-7.8µm
Asci 8 spored IKI -ve,
Paraphyses branched with a few simple ones

It looks like a Durella species and D. connivens seems to fit well

... but it isn't :-)
It is Patellaria atrata. (or "crassispora" because the exudate looks more bluish than olive)

Re : Durella connivens ?
Thanks Zotto.
I did consider Patellaria atrata, but the mature spores did not have the large oil drops which seem to be typical to that species.
Re. 'crassispora' I am not aware of a species with that epithet in Patellaria.

Re : Durella connivens ?
Exactly, the multiguttulate spore content is typical of P. crassispora ined. But that species has wider spores than you indicate, about 8-10 µm.

Re : Durella connivens ?
Thanks Zotto for the clarification.
