Pink Orbilia
Adam Polhorský, 30-03-2016 17:38
Good evening,

this orbilia (0,4-1,1mm) was found found dry on a weathered stump of Quercus sp.

Ascus- 40-50 x 3-4µm, inamyloid in Melzer, and in Melzer+KOH, no croziers found
Spores- only observed in a ascus, narrow, straight, 9-12x 1,5 µm- probably immature
Paraphyses- slightly enlarged at the top, with oil content, septate,
There seemed to be crystalization around the walls of pharaphyses and at the base of the fungus

I think, i  also observed an anamorphic state.

O. vinosa related?

Thank u for your help
Adam

Re : Pink Orbilia
Dear Adam

a nice collection, but when not clearly seeing the spores it will be difficult to classify. The apothecium looks mature, however. Your adaptaion seems not the best since the photos have some roughness.

Clearly this is a member of subgenus Hemiorbilia, based on the hemispherical, somewhat thick-walled ascus apex and the non-capitate paraphyses. Colour and marginal teeth could refer this to O. aprilis, which has spores max. ca. 10 µm, or perhaps to O. vinosa s.l.

Re : Pink Orbilia
Thank u Zotto, i am unable to get sharper pictures from my photosystem- they are already edited, originals were even worse.
I have one more orbilia coming up from Pinus sylvestris, i ll try my best there.

I ll keep this specimen in a humid chamber and try to catch some spores onto cover slips,
until then..

Re : Pink Orbilia
Yes, please try, and if you see more with the naked eyes, please try a pencil sketch.
What did the anamorph look like?

Re : Pink Orbilia
will do,
i thought i captured it in the last picture, or is it branching paraphysis- too hard to tell probably. I ll return to this collection, i examined the largest fruiting body, others are smaller.
There are 7 remaining, hopefully they ll reach maturity.

Re : Pink Orbilia
these are branched paraphyses.
