This years IMC comes roughly 10 years after published
reassessments that greatly increased the estimated numbers
of fungal species. We feel it timely to review these
estimates based on a decade of data gathering and thinking
on the topic. Each talk in the symposium will present the
current status of known diversity for a major group of fungi
with a geographical focus. Contributions will cover macro-,
micro-, lichenized, aquatic, soil-inhabiting, and arthropodassociated
fungi, plus a summary that integrates each of
these presentations. Each talk will address the following
questions for its fungal group: How many species are
known worldwide? How accurate is this number? How is
this group geographically distributed? Which geographic
areas are well versus poorly known? What are the species
overlap between different geographic regions? And what
are the estimated centers of diversity? Thus, each
presentation will function both as a meta-analysis of
current data and a gap assessment to indicate where future
research efforts should be concentrated. In addition to
providing a summary of the state of our knowledge on
fungal diversity, a goal of this symposium is to help inspire
future work on fungal diversity and biogeography so that
significant progress toward our understanding of these
issues will be made by the next IMC.

We have compiled data on macrofungal diversity and
distribution patterns for major geographical regions of the
world. For this presentation, we have defined macrofungi
to include ascomycetes and basidiomycetes with large,
easily observed sporocarps that fruit epi- or hypogeously.
Co-authors provided data on a particular taxonomic group
or geographic area. We then employed a meta-data analysis
to investigate species overlaps between areas, levels of
endemism, centers of diversity, and estimated percent of
species known for each geographic area for each taxonomic
group and for the combined macrofungal data set. Thus, we
provide both a meta-analysis of current data and a gap
assessment to help identify research needs.

Recent studies in Australasia, Hong Kong, South Africa
and Thailand have provided new data towards quantifying
the magnitude of fungal diversity. High global fungal
species numbers rely heavily on there being a relatively
high ratio of unique fungi to host plant species. Data on
host specificity for saprobic fungi is sparse, but a study of
four New Zealand native plant genera; Agathis (1 species),
Metrosideros (x taxa), Nothofagus (5 taxa) and
Rhopalostylis (2 species) has found that 7 out of 10
saprobic microfungi described on Agathis are unique to
Agathis in New Zealand, 0 of 2 are unique to Metrosideros,
16 of 20 are unique to Nothofagus, and 6 of 9 are unique to
Rhopalostylis. Figures for fungi on Proteaceae and
Restoniaceae in Cape Fynbos, S. Africa are also presented.
Is this enough diversity to account for the estimated
numbers of fungal species in the world? This paper will
