Hyaline Dothideomycete with glassy hairs

Hi Guy sent me images of an interesting pyreno with long helicoid spores. Grown on inner face of detaching, dry, little rotten Fagus bark still attached to a standing trunk 20-25 cm thick in perhaps 1-2 m above ground, closely associated with Tubeufia cerea.
Perithecia ca. 150 µm diam (incl. hairs)
Asci *85-100µm x 12-14µm , 8spored, IKI not tested.
Spores helicoidally twisted within the living ascus, ca. 48-55 x 2,5-2,8 µm, with 3-5 septa and rather large LBs
Hairs hyaline, very thick-walled (glassy) with fine lumen.
Zotto

Re:Hyaline Dothideomycete with glassy hairs
Asci are rather thin-walled when alive...
