Apostrasseria ambigua Nag Raj & W.B. Kendr. 1983

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.
