Stromata visible on both sides of the leaf, 4—1 mm. diameter, round, convex on both 
surfaces, on the upper surface smooth, shiny, often becoming more or less coalescent, and 
then up to 1 mm. in diameter and more or less irregular in outline. Single stromata uni- 
locular, scattered irregularly over leaf surface. Loculi with an upper and lower epidermal 
clypeus which is no broader than the loculus. The lateral walls are not so well developed 
and are lieht brown. Loculi 200-300 u diameter, spherical. Asci cylindrical to somewhat 
club- -shaped, paraphysate, briefly pedicellate, 60—70 x 10-14 u. Spores distichous, one- 
celled colourless, ellipsoid, rounded at both ends, 14-16 x 7-9 p.

not so well developed. Locul small, spherical, 160-18C u diameter, usually not penetrating 
right through the leaf, with a thin delicate wall, scattered or in small groups. Asci para-
