Apothecia scattered, superficial, on bark, disc concave, about i mm. diameter, brown; receptacle concolorous, with short cylindrical stalk, clothed with whitish downy hairs which are cylindrical, obtuse, sparingly septate, with thin, hyaline, finely granulate walls, about 70 x 3-3.5 µ. Asci cylindric-clavate, 8-spored, 100-105 x 7-8 µ, the minute pore blued by Melzer's reagent; ascospores 2-3-seriate, narrowly fusoid, 22-32 x 2-2.5 µ; paraphyses cylindrical with pointed tips, 2-2.5 µ wide, no longer than the asci.

A typo ascosporis 22-32 x 2-2.5 µ, ascis longioribus differt.

D. emerici was on herbaceous stems in the Nilgiri Hills, India. Externally it is indistinguishable from Dingley 18986 but yields ascospores 18-22 x 1.5 µ in asci 85 x 8 µ. The hairs of D. emerici vary between hyaline and light brown. Phillip's manuscript notes with the type specimen indicate that he found ascospores 25-30 µ and the size given in the diagnosis was 18-25 x 2 µ. The Indian and New Zealand fungi certainly seem closely allied but in view of the apparent difference in spore size and the widely different substrata I feel it unwise to regard them as identical. Their relationship to D. javanicus Penz. & Sacc., on ferns, with ascospores 16-22 x 2-2.5 µ and D. ochroleucus Penz. & Sacc., on bark, with ascospores 27-28 x 3 µ, needs further study.

On bark of Nothofagus menziesii, Milford, Otago, Feb. 1948, Dingley 18986 (type)

[Notes from Kew Type specimen, PRJ 2010] Several Australian collections in Kew, some doubtful (one looks like a Basidio), but at least one a nice and macroscopically typical collection. Type material in Kew scanty and in poor condition.
