Calycina (white, sessile, aseptate) on Quercus
Viktorie Halasu, 12-05-2022 12:48
Viktorie HalasuHello,

last year (22.IX.) I've found this small reddening discomycete on recently cut xeric Quercus robur branch, in cracks of bark (soc. Orbilia aprilis). Is seems to be close to an indet. Calycina from Fruska Gora (18.VII.2016 on Fagus), but perhaps it is some other (already named) species? Paraphyses had many small VBs in upper part, soon coalescing to one long VBs.

Hi Viktorie,

not really a good idea about this but macroscopically it resembles Phaeohelotium trabinellum which could be a Calycina.

cheers,

Stip

Re : Calycina (white, sessile, aseptate) on Quercus
trabinella(um) is now Leptodontidium and is no Calycina. The fungus here should be a Calycina. It is white and reddening as some Calycinas are, not trabinellum which is (light) colored from the beginning.

Yes, L. trabinellum has yellowish-brownish apothecia and spores with two medium large LBs.

I also think of a Calycina, or perhaps Calycellina. A similarity is with C. leucella, except for the excipulum.

Hello,

thank you for your help. I'll file it under indet. Pezizellaceae, with all those white Calycina and "Cistella-like VB+" collections.
