Acrospermum on moss
Stip Helleman, 09-10-2011 23:29
Stip HellemanBonjour à tous,

Has anyone heard or know about a Acrospermum species parasitic on moss?
This one I found on wood inhabiting moss 1,60 m high on Willow in a marsh.
Spores are roughly 400x4 asci arising from croziers IKI- no inner wall was observed, it seemed that after ejaculation the spores were embedded in a gel sheet instead of a inner ascus
Thanks in advance,
Stip

Hi Stip,

there is A. adeanum. The journal (Mitteilungen der Botanischen Staatssammlung München) with a paper by Döbbeler on it (p.175-191) you may download here (djvu or pdf):

best regards,

Danke Martin,

Re : Acrospermum on moss
Hi Stip,

for some reason I've been studying fungi on mosses lately. I even have a list of some fungi on them. Besides this A. adeanum, A. graminum and A. compressum have been found on mossess, too. There are more than 200 bryosymbiotic ascomycetes.

Best wishes from Marja

Re : Acrospermum on moss
Hi Marja,
Thanks for the tip, I will look out for them too. Are they growing parasitic too?
Microscopically adeanum differs in multiseptate ascospores.

cheers

Re : Acrospermum on moss
Hi,

I think you finding must be a good one. Suppose, that there is only one collection from Finland.
At least I would be happy to find these.
But you know, I'm happy to find anything new for me...

I don't know are these parasitic or not. I just got a list with some "common" text and it doesn't tell you much of a specific species.
