MID CANTERBURY: Christchurch Botanical Garden, dead leaf of Nothofagus fusca, 9 Oct 2001, PDD 74782.

Conidiophores macronematous, hyaline. Conidia hyaline, elliptical, 12–20 µm long × 15–18 µm in diam., strongly catenate and remaining in chains. Filaments 2.5 µm, 0–1 septa per turn, 5–8 coils per conidium. Coiling clockwise (c+) as described by Goos (1985).

New record from New Zealand. This is a typical aero-aquatic fungus with helical, air-trapping conidia. The two species noted in this paper are relatively common members of the genus.
The conidia of H. conglomeratum are generally similar to those of H. tubulosum except the latter has micronematous conidiophores and conidia coiling in the opposite direction. The most recent revision of the genus is that by Goos (1985). However, there have been numerous additions since that publication. A revised provisional key may found on the NZFUNGI website (Anon. 2001–2004).
