Having much the appearance of a large Erysiphe buried in the pubescence of the leaf. Cups subglobose, externary black, margin reflexed. Hymenium rufous. Asci clavate, obtuse. Sporidia hyaline, obovate-oblong, obtuse, subcymbiform, with about four transverse septa, and occasionally an oblique one in the upper division.

On the under side of leaves of Pittosporum crassifolium, near the River Te Waiohingaanga, Hawke's Bay, Colenso.

minuta, subglobosa, ore inflexo, extus nigra, intus rufa, ascis amplis, sporidiis hyalinis obovato-oblongis obliquis subquadriseptatis. (TAB. CVI. Fig. 11.)

Seated on the hairs of Pittosporum crassifolium leaves, near the river Te Waiohingaonga, Hawkes Bay, Colenso (type).

Ascoma about 1 mm. diameter, when dry closed and black, when moistened opening by the folding back of from 4 to 7 lobes to expose a yellowish brown gelatinous disc. Sterile tissue composed of an open network of hyaline hyphae 1 µ wide, encrusted towards the surface with opaque brown matter, embedded throughout in a hyaline gelatinous substance. Fertile area a hymeniform layer of clavate, rather thick-walled, 8-spored asci, about 70-80 x 15-17 µ; ascospores elliptic-cylindric, hyaline, 16-20 x 6-7 µ, at first 3septate, then with up to 5 transverse septa and 1-2 longitudinal septa; interascal hyphae 1 µ wide, anastomosing. No part of the tissue stains blue with Melzer's reagent.

This fungus seems to be akin to Phycopsis and Zukaliopsis, with structure resembling the former and asci more like the latter. Ekmanomyces Pet. & Cif has similar but blackish-brown dictyospores. Protoscypha Sydow. has similar asci and ascospores but is erumpent and non-gelatinous.

[Notes from Kew Type specimen, PRJ 2010] Tiny, dark walled, sessile, more or less globose fruiting body, outer excipulum finely and regualrly sculptured/knobbled; amongst hairs on undersides of leaf. Upper part of ascomata broken off in most of type collection

On the under surface of leaves of Pittosporum crassifolium Hawkes Bay, New Zealand (Colenso).

Scattered or gregarious, sessile, globose and closed at first, then opening by a minute pore, finally saucer-shaped, the entire margin remaining erect or slightly incurved, glabrous, 1/2 - 1/3 mm. diameter ; disc reddish-brown, externally blackish; hypothecium and excipulum formed of very slender, branched, septate hyphae, which pass at the cortex into brownish, grumous cells ; asci broadly cylindric-clavate, apex narrowed and not blue with iodine, 75-80 x 12 µ; spores 8, irregularly 2-seriate, hyaline, elliptic-oblong, sometimes slightly curved, 3-4-transversely-septate, afterwards with one or more vertical or oblique septa, 27-30 x 7-8 µ; Paraphyses numerous, very slender, hyaline, septate, not at all thickened at the tip.
