Hypocreales on undetermined lichen
Bernard Declercq,
12-03-2018 11:00
Dear all,Collected last week on bark of living Castanea sativa tree here in Belgium:
Perithecia semi-immersed, ovoid, 400 µm high, 350 µm diam.pale orange, covered by hyaline hyphae and short white hairs, with hardly protruding orange papilla.
Asci 8-spores, shortly stipitate, rounded apex. Ascospores broadly to narrowly ellipsoid to naviculate, 28-40(51)x11-15 µm, with (3)5(7) transverse to oblique septa and 1-2 longitudinal septa per cell, each end with an up to 9 µm long cilium, filled with minute guttules, smooth, hyaline. Peridium of yellow-orange textura angularis, with thin layer of hyaline, covering hyphae; hairs cylindrical, straight to slightly flexuous, with rounded apex, 25-40x3-4 µm, smooth, hyaline.
Hypocreales remain tough matter to me. Help is welcome. It would be great to have a name for the lichen too.
Thanks in advance.
Bernard

Re : Hypocreales on undetermined lichen
Hi Bernard, I had this species yesterday also for the first time on lichen: Paranectria oropensis.
See in the DATABASE too.
Greetings Peter.

Re : Hypocreales on undetermined lichen
Hi Bernard,
the host lichen might be a poorly developed Cladonia fimbriata

Re : Hypocreales on undetermined lichen
Thanks, Peter, this was the name I was looking for, as I was sure to have seen this somewhere before.
And thanks, Zdenek, for the lichen .
