Hairy Dothidiomycete (?) on Carpinus

Nick Aplin, 30-04-2016 01:38

Salut Ascofrance,

I wonder if anyone has any ideas about this curious, apparently xerotolerant species I collected on a small decorticated (still attached) Carpinus betulus branch on 26/4/16 in the UK:

Ascocarps up to 0.6mm, hairy, black +/-superficial

Ascospores 24-29.2 x 5.5-7.6 µm, smooth, brown, 5-6 septate, strongly constricted at septae

Asci apparently bitunicate

Hairs dark, thick walled, tapering. lighter at apices, septate, with small droplets

Again, I have no clue where this species belongs so any advice would be most welcome.

Merci,
Nick
