Plagiostoma (Gnomoniella) on Euphorbia stems

Hi to everybody

On last week-end I have found some small (up to 0.2 mm in diam.) sphaerical, blackish, inmersed and scattered perithecia growing on dead stems of Euphorbia cf. hyberna at 1600 m of altitude, together with Apiognomonia austriaca and Diplonaevia mollisioides. Only the short conical neck, up to 0.15 mm. protruding over the peridermis of the plant.

I feel this fungus is close (but not the same) to Plagiostoma (Gnomoniella) euphorbiae-verrucosae but in Asturias does not exist Euphorbia verrucosa, my perithecia are smaller, the ascospores bigger with the apical pole acute and the caudal one obtuse.

Maybe un undescribed species?

What do you think?

Thans again

Hi Enrique,

An amazing Gnomoniaceae, really, and perhaps it's an undecribed species, as you said.

I'll send you an email.
