Helminthosphaeria on Quercus wood
Enrique Rubio, 04-08-2021 19:26
Enrique RubioDo you have any ideas for this setose Helminthosphaeria that was growing on decorticated Quercus petraea wood at 1000 m of altitude near ascomata of Orbilia xanthostigma? The aseptate ascospores have at least one apical pore.
Many thanks in advance

Maybe Helminthosphaeria heterotricha?

Hi Andy
In one of your last keys (Mycologia, 106(3), 2014) I can read:
Ascomata setose, asci 4-8-spored, ascospores remaining hyaline, 8-12 x 5-6 mm . . . . . . . . . . . . ............... Helminthosphaeria heterotricha.


Of course the ascospores of my collection were not hyaline.
