Hi! Spores 1 septate; 12-13 x 3um Hairs 35-75
I am struggling with a small pyreno that I collected on bark of Quercus faginea. The pseudothecia grew gregariously and an rather small, around 0,3-0,4 mm. Asci are bitunicate with a fissitunicate dehiscence, 75-85 x 12-13µm. Spores measure 18-22 x 6-7 µm, hyaline and apparently without a gelatinous sheath. The hamathecium is very dense and composed of branched hyphae.The peridium is 30-40 µm thick.
I have been looking into Massaria. The key of the Massarina monograph leads to Massarina corticola, but the asci and spores of this collection are smaller. Probably not a Massarina at all.
Thank you in advance for your help.
Cheers,
Ibai.
this is a species of the genus Didymella. I have similar collections also from bark of Catalpa bignioides.
cheers
