On strawberry leaves
Marja Pennanen, 29-06-2015 14:29
Hi,

once again I'm missing even the genus for my collection.

These brownish are about 0,3-0.4 mm wide.
The spores are about 4-6x1-2 and asci 30-45x4-5.
The paraphyses are noticeble, lanceolate, about 10 longer and a couple micrometers wider than the asci, septate at the base.
At the margin there seems to be wide cylindric hairs about 50x8.
The cells are roundish, coloured and there is some kind of "tuft" on the surface.

For some reason, I do not believe in a Pyrenopeziza species...

Re : On strawberry leaves
No se ve bien la foto del hongo, pero la microscopía es muy similar a Hysterostegiella.

Saludos.
Salvador.

Re : On strawberry leaves
Yes exactly! A difficult genus, needs to see clearly the marginal hairs etc.

Re : On strawberry leaves
Hola,

Thank you Salvador and Zotto. I shoul study this again, but I'm at our country place now with no microscope.  I can collect more here, but that will not help. Be back at the end of this week.

Should have remembered the genus, I collected H. typhae 2010.
Maybe that is too long time for me to remember microscophy, evenif I still remember, where I collected that...

Hi,

here is a photo of the marginal hairs, they seem to have septated base.

Re : On strawberry leaves
Yes, this may be if they are not paraphyses. Now there should exist exudates, as you see here in a photo by Michel Hairaud.

This is H. dumeti and at least it is on Rosaceae, though Rubus stems.

Re : On strawberry leaves
Hi Zotto.

I had the opinion, that the hairs were hidden under the granular matter of the surface, when it was dry. I may be wrong, should rehydrate some to get the hairs at the margin, but there are other peculiar collections waiting.

Heres another photo of the hairs.
H. dumeti is close.
Nice. That would be new for Finland, because as far as I know, no other has collected Hysterostegiellas here.

Thank you.
