Bryophilous Helotiales on Riccia cilifera

Dear Forum!
I could not identify this tiny rose discoid thing with no stipe.
Does anybody have some experience with this?
Thanks: Attila

Re : Bryophilous Helotiales on Riccia cilifera
I do not know at all but there are a few questions:

Could you study the excipulum?

Iodine reaction seems negative?

Are there any paraphyses?

Do you still have it fresh and could make a water mount without pressing? Living asci and paraphyses could be helpful.

Your beforelast photo seems in water, do you also have a photo at high magnification showing the septum in vivo?

Size of apos is around 0.5 mm?

Re : Bryophilous Helotiales on Riccia cilifera
I asked Peter Döbbeler and he suggested it could be Pachydisca amoena:


Only the spores are given shorter and no septum is mentioned.

Re : Bryophilous Helotiales on Riccia cilifera
Sorry for this late ansver, but I was busy in this week.

Unfortunatelly I have not study the excipular part.

Iodine reaction seems mainly negative, but perhaps

wery weakly positive in some immature ascus.

Paraphyses is thin, long-cylidrical, with slightly broad an rounded tips, no pigment bodies.

I cannot have it in fresh, but the collection place where I found it, is exacly known.

The fruiting bodies is 0,1-0,5 mm, resting stalkless near the side and near the base side of the moss-leaves.


It seems to me, that the spores become septate only in the fully mature ascospores.

Re : Bryophilous Helotiales on Riccia cilifera
Thanks for more details. The matter with spore septation requires living asci, it is frequently misunderstood or differently defined. My definition of maturity is: freshly ejected spores. Which they are you can only decide if you have living asci.
