Trichopezizella nidulus sur reine-des-prés (Filipendula ulmaria) ?

Bernard CLESSE, 10-05-2015 14:52

Bernard CLESSE

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.

Re : Trichopezizella nidulus sur reine-des-prés (Filipendula ulmaria) ?

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

Best regards!

and is always without croziers.

Ah? OK! I did not read it.

Thanks Zotto.

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

Re : Trichopezizella nidulus sur reine-des-prés (Filipendula ulmaria) ?

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.

Re : Trichopezizella nidulus sur reine-des-prés (Filipendula ulmaria) ?

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
