Small disco on leaves

Dear friends!


Do you have some idea about the genus of this tiny disco?


I have found it on dead leaves of Quercus robur. Fruitbodies are single, small, orange-beige, 0,2-0,5 mm in diam.


I thought about Pezicula, but apical rings are blued in IKI (colourless in MLZ)


Spores are ellipsoid, 10,9-11,4*2,4-3,6 um, hyaline, with 2-3 guttules (in water, KOH). 


Thank you before,


Irina

Re : Small disco on leaves
Maybe Calycina? Do you have info about paraphyses contents?

Hi Irina & Raul!

Yes, that might be right guess....it seems to me that asci are of Calycina type reaction (although there are number of genera apart from Calycina with that type of euamyloid reaction). Perhaps a drawing of some cell types, most preferably in statu vivo (see Baral 1992 publ. in Mycotaxon, which I can send if still needed) and observation on paraphysal & excipular layer(s) structure & gelification would be sufficiently informative. Also ascogenous system type (croziers vs. simple septate) is crucial. it is not necessary to draw whole block of texture(s) or hymenia - only group of cells.

Cordially,
Neven
