Re : On Abies alba. Dothideo?
Hello 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

Re : On Abies alba. Dothideo?
Hi 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 ?

Re : On Abies alba. Dothideo?
Hi Pavol,

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.
