T he subantarctic islands
of New Zealand have been little explored mycologically. Before
our expedition in March 2000 fungi had usually been collected
incidentally, mainly by botanists primarily interested in plants.
McKenzie & Foggo (1989) provide a complete account of the
history of mycological research on New Zealand's subantarctic
islands. They noted 49 named species of fungi, with a further
2 identified to genus only, plus 2 species of myxomycetes [view
list of taxa reported by McKenzie & Foggo].
The Year 2000 expedition to Campbell Island and
the Auckland Islands yielded more than 3000 collections. Preliminary
examination of the specimens, indicates they include at least
52 species of agarics (3 previously known), 70 species of wood-rotting
resupinate and bracket fungi (5 previously known), 32 species
of rust fungi (15 previously known), 75 species of ascomycetes
(16 previously known), and 20 species of slime moulds (2 previously
known). Although collecting on Campbell Island was intensive,
our expedition spent only limited time on the larger, environmentally
more diverse Auckland Islands, and the record of fungi from these
islands will be especially incomplete. The rust fungi provide
an example -- mainland New Zealand has about 1 species of rust
to every 16 vascular plant species, Campbell Island has a ratio
of 1 to 13, the Auckland Islands a ratio of 1 to 23. It is likely
that many more rust species remain to be discovered on the Auckland
Islands.
Although some of the fungi found on the 2000 expedition
are likely to be undescribed, overall the geographic relationships
of the species found on Campbell Island and the Auckland Islands
appear to be with mainland New Zealand. The majority of the subantarctic
island species are found on similar hosts and substrates in other
parts of New Zealand. Some of the novelties found include an undescribed
Diaporthella sp., a genus previously unrecorded for New
Zealand, and new rust species on Dracophyllum longifolium
and the fern Polystichum vestitum. A few species are
truely subantarctic such as the tiny, grass-inhabiting
discomycete Lachnum enzenspergerianus, now known from
Campbell, Macquarie, Iles Crozet and Ile de la Possession.
