Eupezizella britannica

Also known as Hyaloscypha britannica, sharing habitat and traits with Hyaloscypha aureliella, both on Pinus wood, but with larger spores.

Marginal hairs cylindrical, gradually tapering toward the apex, hyaline, with some colorless surface incrustations.

Asci cylindrical to slightly clavate, thin-walled, with biseriate to irregular spore arrangement in the upper ascus, 50-65 µm long, 6-8 µm wide, with croziers at their base, and an amyloid apical apparatus.

Paraphyses filiform, very narrow, only up to 2 µm wide, without apical swellings, hyaline or with faint vacuolar internal content.

Ascospores subfusiform to slightly allantoid, with tapered ends, smooth, hyaline, thin-walled, with abundant small internal guttules.
