Epiphyllous, forming spots 1-2 mm. diameter, which are made up of numerous minute 
black points. Each point represents a hemispherical, subcuticular perithecium, 170 yu in 
diameter and about 60 v high. Free mycelium wanting. Basal line brown, thin, 0°5 u 
thick, lying flat on the outer wall of the epidermis ; the outer membrane convex, remaining 
covered by the cuticle, 6-7 » thick, parenchymatous, without any decided radial orientation 
except at the periphery. Asci basal, somewhat converging towards the ostiole, sessile, 
aparaphysate, somewhat thickened round the apex, 42-48 x 12-15 uy, eight-spored. 
Spores distichous, ellipsoid, two-celled, not constricted, rounded at both ends, light, grey- 
brown, 7-10 « 4 u.

Stromata epiphyllous, scattered, minute, black, convex, (“3-04 mm. diameter, round 
or oval, unilocular. Loculus developing between the epidermis and the palisade tissue, 
and with its base resting on the latter which becomes concave, ellipsoid, 300-350 u diameter, 
100-120 vu high in the centre; epidermal clypeus black, opaque, 30-40 u thick, and covered 
by thick cuticle which is 15-16 p thick : the clypeus does not always extend over the whole 
length of the loculus, being 200-250 uv. long, lateral and basal w alls of loculus consisting 
of delicate hyphae which are laterally compressed. Asci paraphysate, oblong or ellipsoid, 
tapering somewhat to the rounded apex, eight-spored, sessile, 80-87 x 17-20 u. Spores 
distichous, hyaline, continuous, ellipsoid, rounded at both El 20-24 < 6-7 y
