Cistella geelmuydenii?
Marja Pennanen, 30-03-2011 20:12

I been traveling by bus to get some education in Joensuu. Near the bus stop I picked a Tilia stem, which had something growing on it. These are about 0,1-0,4 mm wide:

Re:Cistella geelmuydenii?
The asci are about 30-35x4-7, croziers are a strong option ;)
I can't say anything about IKI reaction, even if I tried to see it :(
Paraphyses are quite narrow, about 1,5 wide.

Re:Cistella geelmuydenii?
The hairs are about 10-20x3-5 cylinrish and got some spines.
I'm not bery proud of this photo.

Can someone confirm my uncertain determination?

Hi Marja,
it looks a bit like it but i am not sure if it is a Cistella, it could also be some Hyphodiscus species,
geelmuydenii i remember as pure white. H. hymeniophyllus is a option too,this is also a very variable species in IKI reaction.
Can you put the camera back in auto White Balance? ;-)

Re:Cistella geelmuydenii?
Hi Stip,
thanks, I'll check this again this evening. I just don't know, weather I have any descriptions about Hyphodiscus. I've never found such.

There were some white ones and most were coloured. The yonger ones seems to be whitish.

I think my camera has an auto WB setting on now. I just use led lights instead of the original and the light is blue. I could process images to remove some colours, but it would take too much time for "temporary" photos like these.

Re:Cistella geelmuydenii?
I checked this once again.

And wonders do actually happen, I saw a crozier :)

The hairs can have 1-2 septas, are up to 30 micrometers long and only the top cell is spiny.
when KOH was added, the hairs in the preparate did not change color.

Raitviirs "Revised..." don't seem to include description of a Hyphodiscus like this :-/
