This CD-ROM presents a complete taxonomic data set of
all currently accepted yeast species, including
morphological and physiological data, and ribosomal DNA
sequences. The interactive software contains modules for
the comparison and integrated use of physiological,
sequence and morphological information, facilitating the
identification of yeasts using complementary data sets.
Many species are illustrated by microscopic and
macroscopic images. This product will be useful in a wide
range of yeast studies throughout the agro-industrial and
medical sciences.

Ligniphylous discomycetes are developing on the various
woods. Ones of they have special ferments for destroying
of a broad-leaves wood. Other has special ferments for
destroying of conifers. They to some extent show a species
specialization according to plants. Discomycetes are not
aggressive wood-destroying fungi. But some species of
discomycetes produce diseases, death or a depression of a
developing of plant. These fungi settle on a bark of robust
trees and provide a saprotrophic cycle of life. It is not get
up 1,5 meter on a stem of tree. If a resistance power of tree
slacken, fungus change self cycle of life to parasitic. Some
species of Discomycetes develop fruit-bodies only on
coniferous trees. At first they invade the bark of healthy
trees and live as saprotrophic fungi. If a resistance of trees
is weakened, these fungi change their way of life and
become parasitic. When the tree dies, these fungi come
back to the saprotrophic way of life. In accordance with
literature data, 43 species of Discomycetes were reported
on Pinus spp., 37 - on Abies, 18 - on Picea, and 12 - on
Larix. In coniferous forests, Discomycetes develop on
attached and fallen needles and branches in the litter. In the
latter case their number is smaller in comparison with
wood-destroying species.

The biodiversity of Thailand's fungi is poorly known. Until
1990 less than 500 spp. (of all fungi) had been reliably
reported. Since 1990 increased effort has been made to
survey this rich biodiversity. Thailand is entirely tropical
offering a range of habitats from rain forest in the south to
dry deciduous forest in the north. Elevations are from sea
level to over 2500 m (Doi Inthanon). In the last ten years
ca. 3100 specimens, from 40 orders, 96 families, 326
genera and 677 spp. have been added to the BIOTEC
Herbarium. Most accessions were from 1992 to 2001 from
various parts of Thailand. Within the herbarium there are
significant deposits from many researchers having either
short-term or long term associations with young Thai
researchers. These activities continue to the present. A
major effort is being made with the marasmioid and
mycenoid fungi of Thailand but in the course of that work
other agarics have also been collected. Notable records of
these for Thailand include: Cintractia amazonia, Fistulina
hepatica, Crinipellis zonata, Amanita hemibapha,
Strobilomyces velutipes, Dacryopinax spathularia,
Clavulinopsis miniata, Irpex flavus, Steccherinum
rawakense, Craterellus verrucosus, Anthracophyllum
nigritum and Mutinus bambusinus.

Marasmius (1600+ spp.) and Mycena (1200+ spp.) are the
most diverse genera of saprobic basidiomycetes. The
greatest species diversity is in the tropics, although
hundreds of taxa are found in temperate regions of both
southern and northern hemispheres. Nearly all species are
saprotrobic, having important roles in litter decomposition,
nutrient recycling/retention, pedogenesis etc. A few are
parasitic on important food crops. Importantly, some form
antibiotics such as strobilurin. Many species are host- or
substrate-specific accounting for some of the high diversity
seen in tropical forest. Over 460 samples were collected
from various parts of Thailand. Of these, 93% were
identified to species or morphotaxa while 7% remain
unidentified. To date, 100 genera and 51 species are
known. Samples were classified into three major groups of
fungi; namely marasmioid, mycenoid and other
macrofungi. Marasmioid fungi were 25% of the collection,
