Plagiostoma on Euphorbia hyberna

Enrique Rubio, 30-04-2022 12:23

This Plagiostoma with perithecia immersed under the epidermis of stems of Euphorbia hyberna and with more or less central long necks (> 200 microns long) is common in the Cantabrian Mountains. The spores have a median septum and thin, barely perceptible appendages.
I find no affinities with any of the euphorbiaceous species of the genus.
Have any of you ever been able to study it?
Thanks again.
