Apiospored pyrenomycete
Björn Wergen, 19-06-2013 21:14
Björn WergenHi there,

during my vacation in Austria I have found a very small, immersed pyrenomycete on old Typha stems. It has just 0,1-0,3mm broad, black fruitbodies and apiospores, which have a paler and a darker brown cell, 13-15x4-6µm. There is no visible apical structure, IKI- and Congo -.

There is no stroma, perithecia are embedded singly.

Any idea?

Thanks in advance and regards

Re : Apiospored pyrenomycete
Hallo Björn
I wondered about Anthostomella, but I am not convinced - there does not seem to be a clypeus, and you would expect a reaction to IKI. Do you have Sheila Francis' book on Anthostomella? (Mycological Papers No.139)

best wishes
Chris

Hi Chris,

the collection is saved on my pc as "Anthostomella sp.", but just due to the lack of knowledge.

I do not have this paper.

I have found Anisomyces nectrioides as a very similar fungus, but this one is only recorded from Brazil (on Paullinia spp.)...

Re : Apiospored pyrenomycete
I give myself the answer: Didymopleella cladii. It is recorded on Cladium, but anyway, Cladium and Typha are both Poales and everything fits very well.
