Picked as Orbilia
Marja Pennanen, 03-03-2011 21:00
Hello,

back to business with new cameras :)
I picked this as an Orbilia, but it seems to be something else.
It's coming though the outer bark layer and is about 0,5 mm wide.

Re:Picked as Orbilia
The spores are allantoid, (17-) 20-30x4-5 and can contain some droplets.
Asci are 60-115x 10-20, IKI-.

Re:Picked as Orbilia
Dear Marja,

may be a Perrotia?

best regards,

Re:Picked as Orbilia
The paraphyses are a mesh. They are shorter than asci, septate and their tips carry some brown material, can branch and have wider cells and...

Re:Picked as Orbilia
I dont believe this is an Orbilia or Ocellaria ;)
Should I?

Re:Picked as Orbilia
Thank you Andreas,
I know no Perrotias.
I'll check, if I find something of them.

Re:Picked as Orbilia
I think the erumpent habit and the inmvisibility of hairs exclude Perrotia, though the spores look like.

What is the host? Peziculoideae are similar but they are always strongly hemiamyloid.

I fear I don't know this fungus-....

Re:Picked as Orbilia
Hi Zotto,

I'm sorry, I didn't remember to mention the substrate, These grow on a Salix twig, which was still attached to a bigger at the hight of about 1,8 m above the snow level. The snow level here is the highest of Finland, 96 centimeters. Even short people can reach high to trees here now ;)

Re:Picked as Orbilia
Could you try a median section with a razor blade to see the excipulum?

Re:Picked as Orbilia
Hi Marja, the spores looks a bit Encoelioid, they resemble to fuckelii and furfuracea.
I think it is just bursting out of its anamorph.
Cheers Stip

Re:Picked as Orbilia
The spores are very big, I wonder Marja if you cannot take a more close photo of them. Did you use oil immersion?

And asci are totally IKI-?

Re:Picked as Orbilia
Hello,

because of the big spores I looked them with 500x magnification. There was substrate in the preparate, so excipulum wasn't visible. There are only few fruitbodies left now. Maybe I should go and try to find more...

Here's a photo of asci in lugol.

Re:Picked as Orbilia
I looked the photos and this is the best I can do about the cells now.
Even if the specimen is wasted, I'll look still one. It too small anyway.
Lichens came to my mind, but I've been told, that they are not soft and this was.

Re:Picked as Orbilia
Hi Marja,did you forget to include a photo of the excipulum?

Did you see any free spores? They do not have any septa? Your images are with 400x, are they?

Marja Pennanen, 04-03-2011 12:16
Re:Picked as Orbilia
Spores in ascus.
I'll try to get better ones.

Re:Picked as Orbilia
Thanks, that's very good! Only I have no idea still. Maybe something like Crumenulopsis...

Still curious about a section of the excipulum.

Re:Picked as Orbilia
Dear Zotto,

You were too fast, sometimes my photos just are too big and I've got to resize them a couple times.

I saw no septas and I think, that the magnification is 500x. There are many possibilities with the mighty Old Russian, even over 1000x, but they are useless :(

Marja Pennanen, 04-03-2011 23:01
Re:Picked as Orbilia
Hello,

so I tried a section, but that's something I got no lucky with. The tissue is very soft fresh, thin and immersed.
I still got some problems with getting photos and attach a very poor one here.

I was a bit wrong with the paraphyses. They can branch at the tips and maybe be a little wider, but the more wider cells they were of the excipulum or margin.
They may be seen (with imagimation?) on the ealier paraphyse photo above the 50 (or backwards 50).

Re:Picked as Orbilia
It may be better to section such a fungus in the dry state. It must not be a superb section :-)

Marja Pennanen, 12-04-2011 22:05
Re:Picked as Orbilia
Hi,

as it usually happens, I managed to find these more. Now they grew on the inner bark of Salix.
Here's a photo of them.
