In Korea about 2000 species of mushrooms (higher fungi)
have been studied from basdiomyctes to ascomycetes.
Among them, about 1500 species are constructed in
database. This database contains several items;
taxonomical system, the application, the ecological
resources, the geographical distributions. Each of
mushrooms is illustrated with descriptions, photographies
and spores. Also, information retrieval system is available
by using KRISTAL II for query searches on the Web in

Several protocols of areas of endemism methods (Morrone,
1994, Jardine, 1972, Linder 2001) were applied to a
mapped list of 220 species of selected groups of
macrofungi (Stipitate hydnoids, polypores, Amanita,
Laccaria, Psilocybe and Scleroderma. Taxa were chosen
both for practical (better known and collected groups) and
ecological(to represent both saprotrophs and biotrophs)
reasons. The best result, lesser fragmented areas, was
obtained with Linder's method of inverse weighting.
Though three well defined groups were observed they were
not supported enough to be considered robust. Nevertheless
when these groupings were contrasted with vegetation and
altitudinal levels maps it was found an acceptable non
exact concordance with the last one; one subgroup related
with lower altitudes is accordingly distributed. Contrary to
our findings based on the application of parsimony
methods, previous ecological studies in Mexico had shown
a relation of macrofungi distribution and vegetation
(Guzmán and Guzmán-Dávalos 1979, Varela and Cifuentes
1979, Heredia 1989) but they were based solely on
similarity list comparisons. Tan & Wu (1986) in China
rather found that macrofungi distribution was highly
correlated with temperature which agrees better with our
results. In spite of limitations to the use of herbaria data to
apply areas of endemism methods, our results support to
certain extent their applicability.
488 - The 609 red listed fungi in Sweden: an analysis of

Red lists are extremely important instrument in both
national and international conservation work. The recent
Swedish Red List is based on an evaluation of factors that
affect risk of extinction, a system to classifying species into
threat categories developed by the World Conservation
Union (IUCN), which is successively replacing the old
systems around the world. The Red List comprises 609
species, of which 254 are assessed as threatened, selected
from an assessment of the 4620 known Swedish
macromycetes (http://www.artdata.slu.se/home.htm). In
principle, all available knowledge of each of these fungi
have been compiled and analysed; life forms, preferences
of habitats and substrates, distribution within and outside
Sweden, and threats. The poster will summarize their
ecological characteristics and identify the major threats.
The red list can be looked upon as a deficiency analysis of
habitats and substrates. Among the most severe problem is
the large scale on going fragmentation of valuable biotopes
like primeval forest with a high amount of dead wood of
appropriate quality and unfertilised grassland. Today, an
alarming number of fungal populations survive only in
small number of isolated populations. Reference:

Pinus koraiensis is the main coniferous tree in NE China.
The species of polypores on wood of the tree were
investigated, and 79 species were recognized. Among them
23 species are considered as rare species, 31 are occasional
and 25 are common. 16 species were found only in forest
reserves, 12 in unprotected forests, and 49 in both forest
reserves and unprotected forests. 6 species were found on
dead trees, 28 on fallen trunks, 41 on rotten wood and 4 on
charred wood. 19 species occur on Pinus koraiensis only,
and 60 on other substrates as well.
