New Zealand hyphomycete fungi: additional records, new species, and notes on interesting collections

Thirty-eight species of micro-fungi are described as newly recorded in New Zealand. These fungi are mainly found in association with a specific exotic host, Quercus ilex, or the hitherto uninvestigated ecological group of aero-aquatic fungi. Six are described as new: Bactrodesmium nothofagi, Dactylaria leptospermi, Pleurothecium leplospermi, Polyscytalum ciliatum, Pseudoclathrosphaerina spiralis, and Zanclospora ureweri. An existing invalid name in the literature, Psendaegerita foliicola, is provided with a validating description. Keys are provided to the genera Pseudaegerita, Thozetella, and aero-aquatic fungi with helicoid, non-wettable or air-trapping propagules.
