Pyreno on a Sorbus branch
Enrique Rubio, 17-08-2023 19:35
Enrique RubioOn dead branches of Sorbus aucuparia still attached to the tree.
The fungus appears to form erumpent, blackish, stromata on which are placed some very small, more or less ovoid, blackish, glabrous pseudothecia, containing cylindrical, bitunicate asci with eight, greyish or yellowish-grey dictyospores, which react to give a bluish-grey colour in Melzer's reagent. The ascospore is not constricted at the septa. I rule out a Cucurbitaria, perhaps a Capronia with hairless pseudothecia? Teichospora?
Any ideas would be welcome

Re : Pyreno on a Sorbus branch
Hi Enrique,
Very nice, once again.
Not Capronia, cf hamathecium. Did you look towards Thyridium s.l. ?

Hi Alain.
Many thaks for your opinion.
As you say, hamathecium is not compatible with Capronia, but the asci seem to me clearly bitunicate, which does not fits well with Thyridium.
