Fracchiae
Eduard Osieck, 06-08-2019 20:56
This setose pyrenomycete was found on a rotten Carpinus branch (Netherlands). Setae 0,25-0,5 mm, often lacking (broken off?). Asci with long stipe, poly-spored (32). Spores allantoid, hyaline, multi-gutulate, 7-9,5 x 2-2,5 µm.

The genus is fairly easy to determine: Fracchiae of which Fr. broomeana is most well known. The latter species has far more spores per ascus (200+) so has to be excluded. A world key or recent monograph does not exist but a compilation of all available descriptions showed that Fr. pulchella (Sacc.) Lar. N. Vassiljeva is presumably the best match. This species is also known as Acanthonitschkea pulchella Nannfeldt. Features of this species are 32 spores/ ascus, spore length 6-12 um, and long setae (Nannfeldt 1975). The only problem is that it appears only to be known from tropical regions (Africa, Asia).

Are there any records of this or of similar looking species known in Europe?

Any help would be appreciated, Eduard

Re : Fracchiae
you forgot to give a locality for your material :-)

Re : Fracchiae
Oh yes, that is not obvious from my query:
The collection was made in Houten (Utrecht) in the centre of the Netherlands.
