Bonsoir,
est-ce que quelqu'un posséderait un comparatif (photo de préférence, sinon dessin) des spores des deux espèces citées en objet, mettant bien sûr surtout en évidence l'ornementation ? Pour le moment j'ai tenté quelque chose au vu d'un peu de littérature.
Quelqu'un saura peut-être dire si ces deux espèces ont été séquencées et confirmées distinctes ?
Merci.
Patrice

Re : Spores Aleuria cestrica & luteonitens
Dear Patrice,
I'm not aware of any molecular study of Aleuria and Melastiza. I have seen most Czech and Slovak collections of A. cestrica, but A. luteonitens (which should have bigger spores according to various keys) wasn't found here yet. Have you seen this Moravec's article? https://czechmycology.org/_cm/CM344.pdf#page=43
SEM photos of ornamentation of some Aleuria spp. are in the following articles. Not of luteonitens, though.
