Hello everybody,

I didn't get anywhere with this one up to now:

Perithecia erumpent, 0.2 to 0.3 mm in diameter, dark brown, but reddish on top when fully hydrated with hair-like, brown hyphae on the lower half. Those hyphae brown, 3-5 µm diam., with 1 µm thick walls. The simple perithecial wall consists of dark brown, angular, relatively thin-walled cells with 6-10 µm in diameter.

Asci broadly cylindrical, 95-103 x 19-20 µm. Spores muriform, with 3-5 transversal and usually 1 longitudinal Septum per cell, hyaline to slightly brownish when mature, 27-30 x 10-11 µm. Paraphyses present, hyalin to brownish, sometimes branched.

Substrate: hardwood, decorticated thin branch

Many thanks for any hints and best wishes, Stefan

Hi Stefan,
Cucurbidothis pithyophila found on Abies gets close but ascospores/asci a little under your measurements, maybe somewhere additional in this genus perhaps   Go to: https://fungi.myspecies.info/all-fungi/cucurbidothis-pithyophila-var-pithyophila
