On old Raspberries
Marja Pennanen, 28-06-2015 11:34
Hi,

I accidently noticed some Moellerodiscuses growing on old Raspberries=old fruits of Rubus idaeus. They are still undetermined because after searching more, some other fungi were found.

Raspberries seems to carry besides Moellerodiscus Typhula-like basidiomycetes, Cyathicula, Mollisia and these interesting hairy ascos.

They are about 0,2-0,3 mm wide.
The spores are 6-8x2 and asci 18-30x5-7, IKI blue.
Paraphyses are thin walled, somewhat cylindrig and seemingly septate.
The hairs are so odd, that I have no idea of the genus.
They are up to 20x3-4 and seems smooth, often widened at the base, even "bottle" shaped.

Some guidance is needed: Marja

Re : On old Raspberries
No idea! Is it the calyx of the flower where they grow?

Re : On old Raspberries
Hi Zotto,

they grow all over the berry, on the calyx, too.
Really interesting...

The Moellerodiscus is near M. tenuistipes with wide cap (2-3 mm) and not very long stipe.

If you have micros of that I would be very interested.

This genus is badly in need of sequencing, but I fear it is not Sepppo's group.

In any case, spore size/photo and croziers would be interesting to know.

Re : On old Raspberries
Hi,

Moellerodiscus spores were 7-9x3, and asci 60-70x6-7. I may have some  propably poor microphotos, but they are still in the camera, which I'm still using this evening. Be back later.

At the location many berries had "survived" over winter and Moellerodiscuses were on every second of them.
