This species is also known from the United States (DAOM 82810b, on rotten wood, near Onoville, N.Y., 10.V1.1961, S.J.H.).

Colonies scattered, effuse, brown, hairy. Mycelium immersed, composed of pale brown to dark brown, generally smooth, septate hyphae, 1.5 to 4.0 µm wide. Conidiophores arising from a thin stroma, usually in compact fascicles of 15 or more, seldom solitary, simple, erect, more or less cylindrical, brown to dark brown below. progressively paler towards the apex, coarsely roughened, with walls 1.8-2.5 µm thick, 140-305 µm long, 8-10 µm wide at the base, 3- to 7-septate below and terminating in a phialide. Phialides subcylindrical, 90-160 µm long, composed of a poorly differentiated, very slightly inflated venter 21-65 µm long and 10.8-12.6 (-13.5) µm wide, and a long, cylindrical collarette 65-110 µm long and 8.1-9.5 µm wide.

Phialoconidia of two kinds. The first-formed conidium is long, cylindrical, rounded and very thick-walled at the apex and truncate at the base, with a well-marked marginal frill, hyaline, up to 16-septate and 95 µm long, but mostly 7-septate and 62.5-83.5 x 5.5-6.5 µm. Subsequent conidia fusiform, narrowly conical at the apex, truncate at the base with a conspicuous marginal frill, hyaline to subhyaline, up to 5-septate, predominantly 3-septate and 36-58 µm long and 5-6.5 µm wide, sometimes observed in readily seceding chains.

Coloniae dispersae, effusae, brunneae, hirsutae. Mycelium ex hyphis immersis, ramosis, septatis, pallide brunneis vel brunneis, 1.5-4.0 µm lat. compositum. Conidiophora in fasciculis (15 vel plus) oriunda plus minusve cylindrica, basi brunnea vel atrobrunnea, apicem versus gradatim pallidiora, verrucosa, 140-305 µm long., basim versus 8-10 µm lat. 3-7-septata, in phialidem unicam desinentia. Phialides subcylindricae, 90-160 µm long., ad ventrum parum inflatae 21-65 µm long., 10.8-12.6(-13.5) µm lat., et collo cylindrico 65-110 µm long. et 8.1-9.5 µm lat. desinentes. Phialoconidium princeps longe cylindraceum, apice rotundatum, basi trun¬catum, hyalinum, ad 16-septatum et ad 95 µm long. sed plerumque 7-septatum, 62.5-83.5 x 5.5-6.5 µm; cellula apicali in apicem pariete maxime incrassato. Phialoconidia sequentia fusiformia, apice anguste conica, basi truncata, hyalina vel subhyalina, ad 5-septata, plerumque 3-septata, 36-58 x 5.0-6.5 µm aliquando in catenulas fragiles observata.

Habitat: In ligno putrido, New Zealand.

Typus: Auckland Province, Waitakere Range, Upper Piha Valley, 9.X.1963, PDD 21599 (DAOM 93957a).

Colonies effuse, black, hairy. Mycelium immersed, composed of pale brown to brown, smooth, septate hyphae 1.8-4.5 µm wide. Conidiophores solitary, scattered or densely crowded, simple, erect, more or less cylindrical, brown to dark brown, smooth, with walls 1.0-1.5 µm thick, 150-230 µm long, inflated and 2- or 3-lobed and up to 16.2 µm wide at the immediate base, then 7.2-9.0 µm wide and 2- to 5-septate, terminating in a phialide. Phialides subcylindrical, 95-155 µm long composed of a poorly differentiated, very slightly inflated venter 30-40 µm long and 7.5-10.5 µm wide, and a long cylindrical collarette (60-)80-100(-120) µm long and 8-11 µm wide. Phialoconidia of two kinds. The first-formed conidium is long, cylindrical, rounded at the apex and narrowly truncate at the base, subhyaline to pale brown with the basal cell hyaline to subhyaline, rarely up to 18-septate and 120 µm long, but mostly 9- to 12-septate and 83-105 x (5.2-) 5.5-6.5 µm. Subsequent conidia fusiform, straight or slightly sigmoid, narrowly conical at the apex, truncate at the base, end cells hyaline, median cells pale brown, predominantly 7-septate and (27-)30-40(-47) x 5.0-6.5(-7.0) µm.
