Foliicolous. Conidiomata stromatic, pycnidioid, amphigenous, scattered to gregarious and confluent, intra-epidermal in origin, at first immersed, becoming erumpent, elongate oval to irregular, in section broadly conical, up to 300 µm long, 170-230 µm wide, and 90-140 µm deep, irregularly plurilocular with convoluted locules, glabrous, dark brown to black, initially closed, ultimately with one to three, circular to oval, 30-40 µm diam. apertures in the apical wall, covered with a pearl white or creamy, gloeoid globule or cirrhus of conidia; wall 15-20 µm thick, concolorous for the most part, of "textura angularis" of dark brown, thick-walled cells. Conidiophores lining the locules, reduced to conidiogenous cells. Conidiogenous cells annellides, subcylindrical to conical, mostly hyaline, occasionally dark below, smooth walled, 5-8 x 2-4 (x = 6.5 x 2.9) µm, proliferating percurrently two or three times, invested in mucus. Conidia blastic-annellidec, amerosporous, fusiform with somewhat apiculate ends, hyaline, smooth walled, 8.5-14 x 3-4.5 (mean = 11.5 x 3.9) µm, bearing funnel-shaped to irregular, mucoid appendages at both ends.
KNOWN DISTRIBUTION: New Zealand.
HABITAT: On leaves of Podocarpus totara G. Bern. ex D. Don.
Foliicola. Conidiomata stromatica, pycnidioidea, amphigena, dissita vel gregaria et confluentia, originem intra-epidermalia, erumpentia, anguste ovata vel irregularia, usque ad 300 µm long., in sectio late conico, 170-230 µm diam., 90-140 µm alt., irregulatim plurilocularia, loculis convolutis, glabra, atrobrunnea ad nigra, primo recondita, deinde in parietem apicalem una sed duobus vel tribus, circularibus vel ovalibus, 30-40 µm diam. aperturiis praedita, in cirrhoso vel globuloso, gloeoideo, albido, vel eburneo massa conidiorum obtecta; paries 15-20 µm cr., plerumque concoloribus, ex "textura angularis" e cellulis atrobrunneis et crassitunicatis compositus. Conidiophora circa cavitatem conidiomatis enascentia, cellulis conidiogenis redacta. Cellulae conidiogenae annellides, subcylindraceae ad conicae, plerumque hyalinae autem interdum prope basin fuscantae, laeves, 5-8 x 2-4 (mean = 6.5 x 2.9) µm, bis vel ter percurrenter prolificantes, in muco involutae. Conidia blastico-annellidica, amerosporacea, fusiformia, utrinque aliquantum apiculata, hyalina, laevia, 8.5-14 x 3-4.5 (mean = 11.5 x 3.9) µm, utrinque infundibulares vel irregulares, mucosas appendices ferentes; ratione conidii long.:lat. = 2.9:1.
SPECIMEN EXAMINED: PDD 41572 (Holotype), Forest Hill Scenic Reserve, 18 mi (1 mile = 1.609344 km) N of Invercargill, New Zealand, 18.IV.1974, B. Kendrick (KNZ 707).

Zelandiocoela ambigua (Nag Raj & W.B. Kendr.) Nag Raj 1993

Specimens examined: 1. PDD 41572 [Holotype], on P. totara, Forest Hill Scenic Reserve, 18 mi. N of Invercargill, New Zealand, 18.v.1974, B.Kendrick (KNZ 707); 2. DAOM 215263, on Podocarpus sp. in litter, Tunnel entrance, Milford, New Zealand, 1.IV 1980, B.Kendrick; 3. DAOM 315326, on leaves of Podocarpus hallii, Governor's Bush Track, Mt. Cook National Park, South Island, New Zealand, 3.IV1980, B.Kendrick.
Foliicolous. Conidiomata stromatic, pycnidioid, amphigenous, scattered to gregarious and confluent, intra-epidermal in origin, immersed, eventually becoming erumpent, elongate-oval to irregular in outline, broadly conical in section, up to 300 µm long, 170-230 µm wide and 90-140 µm deep, irregularly plurilocular with convoluted locules, glabrous, dark brown to black, initially closed, ultimately with one to three, circular to oval, openings in the apical wall, 30-40 µm diam., covered with a pearl white or cream, gloeoid globule or conidial cirrhi; wall 15-20 µm thick, of textura angularis with thick-walled, brown to dark brown cells. Conidiophores reduced to conidiogenous cells, lining the locules, and invested in mucus. Conidiogenous cells subcylindrical to broadly conical, mostly colourless, occasionally darker in the lower part, smooth, 5-8 X 2-4 [mean = 6.5 X 2.9] µm, with two to three proliferations. Conidia fusiform with somewhat apiculate ends, unicellular, colourless, thin- and smooth-walled, 8.5-14 X 3-4.5 [mean = 11.5 X 3.9] µm, with funnel-shaped to irregular, mucoid appendages at both ends.
Known distribution: New Zealand.
Habitat: On leaves of Podocarpus hallii, P. totara and Podocarpus sp. in litter.
