Asco on Pinus bark
Marja Pennanen, 05-04-2011 18:16
Hello,

I found these on the bark of a living Pinus sylvestris. They are about 0,5-0,6 mm wide when mature.
The underside is darker and They are greyish when young.

Re:Asco on Pinus bark
The spores are about 7-12x1,5-2,5 and asci 45-55x5-6, IKI+,croziers may be a possibility.
The paraphyses are 1,5-2 wide and septate.

Re:Asco on Pinus bark
There were some margin or underside, brown structures, which could be even 30x3-5 sized.

This don't seem to be a Mollisia or what: Marja

PS. Now I can't find the specimen, forgotten to Joensuu or lost on the road :(

Re:Asco on Pinus bark
Hi there,

because I lost the specimen, I looked for these yesterday and found easily. So the species may not be very rare.
Now I know, that the spores may have a septa and the hymenium can be greyish, too.

I've tried to determine these and now suppose they could be some Microscypha sp. Just don't know which species :(

Does' someone have a suggestion?

Hi Marja,

can you perhaps tell us if there are hairs? For now I don't know what it can be :D

regards,

Hi Kazuya,

I mentioned "brown structures, which could be even 30x3-5 sized". I think. that they may be taken to be hairs.

Re:Asco on Pinus bark
I tried to take a photo on my toymicroscope, but managed poorly.
I attach a photo here anyway.

So what do you think, can it be hairy?
