Ostropoloid fungus on Hibiscus

Enrique Rubio, 12-03-2026 19:44

Hi to everybody.
Can you give me any suggestions about this ostropoloid fungus that grows in large groups on Hibiscus syriacus wood? The asci show a reddish reaction in IKI even after pretreatment with KOH, the paraphyses lack a pigmented epithecium, and the spores appear to form chains of cuboid, prismatic or almost roundish part-spores that quickly disarticulate.
I don't even know if it is Stictis, Schizoxylon, or some other related genus.
Thank you in advance for your help.
