this fungus (black 0,5-1mm) was found on a dead fallen branches of Abies alba. I do not know the genus / species.
Spores: hyaline dictyospores with (1-3)4-5 horizontal and 0-1 vertical septa
18-27 x 6-10 µm
Thank you for your help,
Pavol
in my opinion is this
Curreya pityophila (J.C. Schmidt & Kunze) Arx & E. Müll., Stud. Mycol. 9: 80 (1975)
Synonymy:
Cucurbidothis pityophila (J.C. Schmidt & Kunze) Petr., Annls mycol. 19(3-4): 201 (1921)
Cucurbitaria pityophila (J.C. Schmidt & Kunze) De Not. [as 'pithyophila'], Sfer. Ital.: 60 (1863). After IF, see also Database.
I search the species for a long time, however, she has not thought yet.
Greetings Peter.
Hi Pavol,
Just some questions :
could you describe ascomata ? Are they sphaerical (or conchate ?) ? Do they collapse when dry ? We don't see very well with pictures.
Could you also give more informations about hamathecium ?
Described ascospores alone are not enough to name a fungus.
Alain
ascomata are not sphaerical (I can not shoot better so I'll try to draw a picture). It is quite strong and even after drying, keeps its shape.
Pavol
p.s. Ostreola formosa ?
this is clearly not Curreya pithyophila, which has globose and clustered ascomata. Your recolt indeed seems to fit Ostreola formosa, which was described by Barr as having spores around 15-21x6,5-9,5µm.
Is it possible to receive a part of this collection for studying?
regards,
björn
It's better !
I thought of course at Mytilinidiaceae.
