BAY OF PLENTY: Urewera National Park, Ngamoko Track, dead twig of Nothofagus fusca, 11 May 2001, PDD 74766.

Colonies sporodochial, white, globose, up to 250 µm diam., excluding setae. Conidiophores arising from small basal layer of dark brown, septate hyphae; conidiophores brown, up to 50 × 4 µm before branching sympodially or penicillately. Conidiogenesis enteroblastic, phialidic. Conidiogenous cells forming terminal elements of all branches and covering surface of the sporodochium. Conidia hyaline, aseptate, 6–8 × 1 µm. Setae circinate, septate, hyaline to pale brown, sympodially branched, smooth, projecting up to 350 × 3 µm.

New record from New Zealand. Volutella, Myrothecium, and Sarcopodium are three genera of sporodochial hyphomycetes bearing setae. In Volutella the hairs are straight, generally at the periphery of the sporodochium, and the conidia aggregate in slimy masses. Myrothecium also has wet spores and the conidia are black to green in mass. Sarcopodium has dry or wet spores and setae distributed throughout the sporodochium (Sutton 1981). Additionally, in Sarcopodium the setae are often coiled, verrucose, and pale brown. Watanabe (1993) provided a key to the genus. S. tortuosa and the equally common S. circinatum were described by Ellis & Ellis (1985). The New Zealand collection differs from the published description (Ellis & Ellis 1985), which includes yellowish or reddish brown sporodochia, conidia in a slimy orange mass, and setae that are sometimes verrucose.
