Hello,Two days ago I found this interesting eutypoid fungus growing on ?possibly Alnus, or other similar thin twig of broadleaf shrub.
It has obviously protuding necks (up to 10 per protrusion) up to 1.7 x 0.3 mm in size. Asci (55-)-80-90 x (8-)10-13 µm, Spores ca 13.5-14.5(-17) x 3-3.5(-4) µm, fainly septate, small guttulate.
Regards,
Dimitar

Re : Diaporthe?
I have checked Wehmeyer's monograph (1933), and as under Melzer's reagent there is an apical annulus seen; spores are sometimes curved to slightly inequilateral, faintly septate, it seems to be close to Cryptodiaporthe hystrix on Acer, Alnus viridis (long-fusiform spores), and C. hranicensis (if grown on Tilia).

Hi, why not Amphiporthe/ Diaporthe leiphaemia on Quercus ?

Re : Diaporthe?
Hi, Peter!
Interesting proposal, but the substratum seems to be dry twig of Alnus.
The beaks ale elongate and somewhat flattened, spores are mostly 2.5-3(-4) µm
wide.
Cryptodiaporthe hystrix (=Apiognomonia hystrix, according to Sogonov et al. 2008, Stud. in Mycol.).
