Nivicolous myxomycetes from alpine areas of south-eastern Australia

Abstract

Nivicolous myxomycetes were collected from alpine areas of south-eastern Australia during the period of middle to late October 2004. Most collections came from the high-elevation area around Mount Kosciuszko, the highest peak on the continent at 2228 m, in the Snowy Mountains of New South Wales, and additional collections were obtained from two areas, Mount Buller and Mount Hotham, in the Victorian Alps of northern Victoria. Approximately 300 collections were obtained during a period of 2 weeks, including species such as Diderma alpinum, Didymium dubium, Lamproderma ovoideum, Physarum albescens and P. alpinum, not previously known to occur in mainland Australia. Lamproderma maculatum and L. zonatum were collected for the first time in the southern hemisphere, and another species of Lamproderma was described as new to science in a previous paper. In contrast to most other areas of the world where nivicolous myxomycetes have been studied, species of Diderma have been represented poorly among the collections from Australia.
