In the Catalogue and Bibliography of Australian Fungi, all
names applied to Australian fungi are arranged under
accepted names, with a comprehensive listing of literature
records. Treatments for basidiomycete macrofungi are
complete, and data from the first volume is accessible online.
Some macrofungi are recorded from Australia only as
names on herbarium specimens. Such records will soon be
accessible through the development of on-line specimen
databases. Mapping schemes are generating large numbers
of unvouchered sight records for selected macrofungi.
Information from different types of records (literature,
herbarium and sight) needs to be integrated and assessed. It
is apparent that the take up of names and the quality of
records for Australian macrofungi varies considerably. The
take up of names refers to how widely and with what
confidence names are applied. Quality is measured by such
things as the amount of descriptive data supporting the
record and whether there are vouchers. Most species based
on Australian types have been disposed among modern
genera, but often are known only from the type. For species
based on extra-Australian types, numerous Australian
records appear to be misapplied. A scheme will be outlined
for coding the status and reliability of names and records.
Filters can be applied according to the various purposes for
which data might be used (such as nomenclature,
conservation status, distribution, quarantine, identification
or regional censuses).

Many authors have attempted to explain present-day
species-level distributions of Southern Hemisphere fungi
with reference to ancient continents and geology. We
suggest that present-day species-level distributions are
more likely to reflect the present-day proximity of
landmasses, or anthropogenic factors, than they are to
reflect the ancient geology of Gondwanaland. The question
of the influence of Gondwanaland on the distribution of
Southern Hemisphere fungi needs to be addressed by
considering phylogenies at higher taxonomic levels. Some
examples are provided, including Cyttaria and
Torrendiella. The extent to which general fungal

distribution is still influenced by the events of 20-80
million years ago will be known only after many more
robust phylogenies are available for groups of Southern
Hemisphere fungi at about the level of genus or family.
38 - Coprophilous ascomycetes of Australia

Coprophilous ascomycetes of Australia This short narration
is a summary of approximately three years research into the
coprophilous ascomycetes of Australia. The culmination of
this project is a recently completed fully illustrated manual
documenting these fungi. The project was funded by the
government financed Australian Biological Resources
Study (ABRS). A total of 180 species of ascomycete fungi
were identified 20 of which (=11%) represent hitherto
undescribed species. The most frequently encountered
genera include: Podospora (31 species), Sporormiella (19
species), Chaetomium (16 species) and Ascobolus (13
species). This presentation will include illustrations and
discussion of a few of the most noteworthy taxa. The
completed publication will also include the hitherto
unpublished research of the late Harry Dade who in his
retirement years also worked on Australian coprophilous
fungi. The performing of this research also highlighted the
urgency of upgrading of keys and the great need for more
direct observations of living fungi on their natural
substrates.

Saprobic ammonia fungi, such as Ascobolus denudatus,
Peziza moravecii, Tephrocybe tesquorum and Coprinopsis
phlyctidospora were observed both in New Zealand and
Australia. Morphological characters of collections of each
fungus from New Zealand and Australia broadly fit within
the species concepts of the same ammonia fungi from the
Northern Hemisphere. The genetic variation among the C.
phlyctidospora collections that were obtained from the
Netherlands, Japan, New Zealand and Australia was
examined by analyses based on the ITS rDNA sequences
and by inter- and intracompatibility of the isolates from
Japan and those from New Zealand and Australia. C.
phlyctidospora is a species complex and individuals
currently recognized as C. phlyctidospora in the Northern
Hemisphere and those in the Southern Hemisphere are
