Hi Enrique,

Really no subiculum ?

Ascospores seem to be very slightly striated, aren't they ?

Alain

Hi Alain

Yes. You are right because they are some rest of a subiculum not well visible when the ascomata are wet, but yes when dried. And it's possible the ascospores are very fienelly striate, but very difficult to observe it with my optica.

What's your idea?

Thanks again!

My idea was Byssosphaeria schiedermayeriana, even if we can't see the usual apex.

In wet conditions, it can be hardly recognizable.

You can check it, it's just an idea, perhaps I'm wrong.

Alain

PS : ascospores are perhaps not striate

HI Alain

Perhaps Byssosphaeria is a good genus for my fungus but I think it's not schiedermayeriana because any ascomata has the typical periostiolar color and morphology. By the way I read Barr's paper on Herpotrichia and its allies, and I have not seen a Byssosphaeria species that matches with this fungus.

Thanks, Alain

like Alain I thought of Byssosphaeria schidermayeriana. It is tricky because the typical subiculum and orange apex most often lack when it is found on submerged wood. However the ascospores in Enrique's fungus are a bit small for B. schidermayeriana.
In that genus the asci are fairly long-stipitate, is it the case here?
Saludos,
Jacques

HI Jacques

Yes. The asci are long stipitate

Thanks for your replay
