Bonjour à tous,Ci-joint ce que je pense être Trichopezizella nidulus sur tige morte de reine-des-prés (Filipendula ulmaria) dans un fossé humide.
a) poils cylindriques, septés, bruns sauf à l'extrémité légèrement enflée qui est plutôt hyaline 112-118x4-8
b) asques octosporés, à crochet à la base, IKI+ : 53x5
c) paraphyses lancéolées-subulées, dépassant longuement les asques : 81x4
d) spores étroitement fusiformes : 8+13x1,2-2
Qu'en pensez-vous ?
Bernard

This is T. rubroguttata, though this is not very clear, there are samples with and without croziers, and this character is not known in the type.

OK Zotto, big thank you for your opinion! I see Trichopezizella nidulus has slightly smaller spores.
Best regards!

Hi Zotto,
i never heard of T. rubroguttata - can you tell me where this species is published? I have often found "nidulus" on Filipendula, and knew about the problem with the croziers (not at least from you).
Kind regards from Lothar

Hi Lothar
musst du nur in Index Fungorum schauen. Gilbert Moyne wrote about the fungus, but did not care for the croziers....
Trichopezizella rubroguttata (Svr?ek) Moyne, Ascomycete.org 6(5): 135 (2014)
= Dasyscyphus rubroguttatus Svr?ek, ?eská Mykol. 21: 65 (1967)
The species was described by Svrcek who likewise overlooked the value of croziers.

Hi Zotto,
thank you very much. Then there is a name for the form on dicots we always determined as nidulus s.l.
Kind regards from Lothar
