Trematosphaeria (?) on ericaceous host

Hi again


I need again your help with these small (uo to 0.7 mm), gregarious, blackish, conical, conspicually papillate, allways superficial pseudothecia with trabeculate hamathecium, 4-spored clavate asci with 3-septate hyaline and smooth ascospores, later brownish, verrucose, many times with end-cells paler. No gel-sheath, no appendages at all.


The fungus grew on decorticated twigs of an ericaceous, lignified, host at 1800 m of altitude.


In 2005 keys on this genus (Tanaka, Harada & Barr) I don'find a species that matches with my collection.


Have you some idea?

Re : Trematosphaeria (?) on ericaceous host
Hey Enrigue,
This fungus is really interesting. -I suppose it is not from freshwater.  The shape of asci and the pseudoparaphyses do not fit Trematosphaeria. So...Please is it possible to send it to me for sequencing? I suppose it may be something new.

Thanks
