Dear colleagues,

I have found a small disco on the wood of Quercus robur. Fruitbodies are 0,2-0,5 mm, some of them short-stalked, some prostrate.

Asci blue in IKI, I haven't seen any croziers.

With best regards,

Irina

Spores 5,6*9-2,2*2,7 um, prolate hyaline

There were few spores in all preparations, see also drawing attached

Re : What's this?(Hyaloscyphaceae?)

Hi Irina,

with this sparse information about hairs and asci??

But anyway, the spores resemble of Hyaloscypha daedalea which can be found on Quercus wood, preferably on wood laying on the ground or root pieces where you can find Dasyscyphella nivea also.

cheers,

Stip

Re : What's this?(Hyaloscyphaceae?)

Stip,

fruitbodies are in bed condition, so it took me a lot of time to find hairs, but I did it (hope so).

Hairs?

Stip Helleman, 10-12-2011 02:40

Re : What's this?(Hyaloscyphaceae?)

Hi Irina,
it looks like hairs and of Hyaloscypha type too to me, did you make ascus measurements?

cheers Stip

Re : What's this?(Hyaloscyphaceae?)

No, but I'll do it on Monday.

Sincerely,

Re : What's this?(Hyaloscyphaceae?)

Dear Stip,

Asci are 35-51*3,5-5,8 um

Cheers,

Re : What's this?(Hyaloscyphaceae?)

Hi Irina,

ascussize fits good too, although you did not see croziers I would say it is H. daedalea for the more wedge formed spores instead of H. fuckelii var alniseda, if you want to look for croziers, try in CR and look for young asci.

Cheers,

Stip

Re : What's this?(Hyaloscyphaceae?)

Thank you very much for help!

Unfortunately due to our ukrainian realities now I don't have Crezyl blue:(

With best regards,

Hi Irina,

Re : What's this?(Hyaloscyphaceae?)

Oh, its good, because I have no problems with Congo Red:) Thank you. I'll try to see croziers.
