Ceratosphaeria-like fungus
Enrique Rubio,

Hi friendsThese isolated, non-stromatic, blackish, glabrous and up to 0.5 mm high perithecia, with a short conical papilla, were found semi-immersed or subsuperficial on indeterminate semirotten hardwood in an environment far from water, with perithecia of Natantiella ligneola.
The asci have a conspicuous and very refringent apical apparatus, so much so that at times it even appears amyloid. Its characters seem compatible with those of the genus Ceratosphaeria, but the perithecia lack long necks and the spores have smaller dimensions that seem to rule out C. lampadophora. Do you have any idea that could help me?

Re : Ceratosphaeria-like fungus
Hola Enrique,
if I were you I would consider the genus Pisorisporium, aquatic, with such ascomata and ascospores and a truly amyloid apical ring.

Good luck,
Jacques

Re : Ceratosphaeria-like fungus
Thanks a lot, Jacques. It is the correct genus with euamyloid asci!
I will check your article tomorrow to see if it is a good match with any of the species, although in this case the wood was well away from the water.
Nice to hear from you.
