Bonjour à tous,
Has someone already met this Pyrenopeziza with unusually long hairs ?
These apothecia were on a previous year's stem of Cirsium palustre , among Pyrenopeziza carduorum, P. atrata and Unguicullela incarnatina (the tiny white thing scattered among).
Hairs up to 100 µm and 8 septa assembled into strands at margin
Ascus 40-50 x 5-6 µm, H+, IKI-, PS 20-22; spores 8-10 x 1,8-2 , OCI 0,5
Paraphysis x1,5-2,2. EE T globulosa , wall dark, diam. 8-12 µm.
Could it be a singular form of atrata as the other characters would fit ? I also wonder whether someone has already sent such fungus but I can't trace it (ENrique ?) and feel sorry about it if it is the case.
Merci pour vos avis
Amitiés. Michel
I think I see a positive IKI reaction there.
I assume you know my folder
Rumex - Cirsium hairy
There you said IKI intense blue. There are several samples on Rumex but one on Cirsium.
Zotto
Many thanks once again, Zotto.
In your file there is a collection of mine on Rumex in La Moleson (Switzerland) in July 2012 which seems close but for the larger spores 10,5-14 x 2-3 (versus 8-10 x 1,8-2 on Cirsium ) and larger ascus and wider paraphyses. The same type of hairs.
I can see Nicolas had such a collection too.
Amitiés. Michel
That on Cirsium by Björn Wergen hat spores small: 8,5-10x1,3-1,6µm
And one on Cardamine also by him again 6.7-9.8 x 1.5-2.1
So i should make a separate Rumex folder
