Hyalopeziza-like on Fagus
Marc Detollenaere, 21-12-2024 12:45
Marc DetollenaereDear Forum,

On naked wood of Fagus, I found some hairy discs with dark hymenium.The hairs were whitish,partially glassy, septated and cylindric .
Spores were cylindric, 8.3-9x2.3-2.9µ and contained 2 guttules.IKI reaction apical apparatus was positive (blue).Hyalopeziza seemed to be close.
Andgelo Mombert suggested Cenangium of H alnicola .
Any suggestions? Hyalopeziza valesiaca?

Re : Lasiobelonium-like on Fagus
Hello,
Perhaps Cenangium alnicola ?

C. alnicola is a fungus with long brownish hairs, resembling a Lasiobelonium.

Re : Hyalopeziza-like on Fagus
Sorry, I can't.  Best would be to provide the excipulum. You say the hairs did not react on IKI, but do you mean the asci?

Re : Hyalopeziza-like on Fagus
Excipulum seems to be text prismatica.Hairs are slightly tapering and glassy. Croziers are present.
Could it be Dematioscypha delicata or dematiicola?

Re : Hyalopeziza-like on Fagus
Dematioscypha has longer hairs and inamyloid asci (except for D. castaneae).

I would rather search in Psilocistella (quercina).

Re : Hyalopeziza-like on Fagus
You are right Hans-Otto.
It is exactly as the description in the article of Quijada(2014)
Thx
