Melastiza sp. with too large ascospores
Benko Gabor, 05-06-2023 14:04
Benko GaborDear Ascofrance, I need your help. I found this Melastiza sp. in Tarvisio Italy, not far from a riverbank, next to a pile of gravel accumulated due to construction work, I found these brick-colored apothecia. Their size is 2-4 mm. A few centimeters away, a bryophilous species also appeared on the pioneer mosses in the same area. I don't know if there have been any previous instances of fires in the area, but it cannot be ruled out. The majority of spores measure 18-19 um in length (excluding ornament), but there are also larger spores measuring 21-22 um in length. At the junction of the networks, pustules can be found. What Melastiza species does have so large spores? Am I on the wrong track?

Re : Melastiza sp. with too large ascospores
Parece Melastiza chateri típica, con esporas ligeramente más grandes, te dejo un par de imágenes mías de la especie con las medidas de las esporas y las paráfisis.
Saludos.
