Colony effuse, caespitose to woolly, black. Superficial mycelium aggregated, hyphae 3.5-4 µ wide, pale brown to brown with asperate walls. Phialophores reduced to simple, sessile phialides arising from modified cells of the superficial hyphae. Phialides lageniform, 35-50 [44] µ long, pale brown and concolorous throughout; venter short, asperate, broadly conical or subglobose; 6-8 [7.1] x 6-9 [7.4] µ; collarette much longer, cylindrical, often slightly curved, smooth-walled; 28-41 [38] x 3-3.5 µ; transition from venter to collarette abrupt; ratio of mean lengths of collarette/venter = 5.3:1. Conidia extruded singly; cylindrical, apex rounded, base truncate with a minute marginal frill; straight or slightly curved, 1-septate, hyaline, smooth-walled, 22-30 [26.5] x 2.5-3 (-3.5) [2.7] µ; mean conidium length/width ratio = 10:1.

Known distribution: New Zealand.

Habitat: On leaf of Dracophyllum traversii

Colonia effusa, atra, caespitosa vel lanata. Mycelium superficiale aggregatum; hyphae 3.5-4 µ lat., pallide brunneae vel brunneae, parietibus asperis. Phialophora ad phialides simplices et sessiles redacta et ex cellulis mutatis hypharum superficialium enascentia. Phialides lageniformes, 35-50 [44] µ long., pallide brunneae et concolorae; venter brevis et asper, late conicus vol subglobosus; 6-8 [7.1] x 6-9 [7.4] µ; collum multo longius, cylindraceum, laeve, et saepe leniter curvata; 28-41 [38] x 3-3.5 µ; transitio ex ventre ad collum abrupta; ratio long. colli et ventris = 5.3:1. Phialoconidia singulatim extrusa, cylindracea, apice rotundato et base truncata minutam fimbriam marginalem ferente, recta vel leniter curvata, 1-septata, hyalina, laevia, 22-30 [26.5] x 2.5-3 (-3.5) [2.7] µ; ratio conidii long./lat. = 10:1.

C. curvata resembles C. emodensis and C. scabrida. It differs from C. emodensis in having larger phialides with longer, often curved, collarettes, and in its larger conidium bearing a minute marginal frill at its truncate base. It is distinguished from C. scabrida by its predominantly lageniform phialides with abrupt transition from venter to collarette, and by its longer conidia.
