systematic observations are completely lacking. The aim of
this contribution is to present a new project, which may be
important for considerations on distribution and diversity
of fungi in European mountains. The systematic research,
carried out throughout two growing seasons so far, has
been focused mainly on lower mountain belts, but
observations in dwarf pine communities and alpine
meadows have also been done. After only two years of
study, the number of fungi recorded from this area
increased considerably and some very interesting and rare
taxa were found. The most interesting recent findings will
be presented e.g. Mycena oregonensis, Entoloma
farinogustus and other.

Sevan National Park was established in 1978 to protect
largest in Armenia and one of the largest alpine lake in the
world, lake Sevan and the surrounding areas. Overall
150.100 ha are protected, including 24.800 ha of dry land.
It is located between many of mountain ranges, at the
1897-2100 m above sea level. The aim of this investigation
is to study the composition of the macroscopic fungies
communities of the Sevan National Park. Special attention
is paid to the biodiversity of edible, poisonous and
medicinal mushrooms. As a material for this investigation
was the collection of fungi gathered in different part of
Sevan National Park, as well as critically treated
collections of the Republic's herbariums and all other
literature data. As a result of the preliminary investigation
and special studies of macrofungi's biota in Sevan National
Park, 186 species and subspecific taxa from 10 orders, 30
families and 84 genera of Gasteromycetes, Aphyllophoroid
and Agaricoid mushrooms are identified. The biota is
characterized by the domination of xylotrophs, humus
saprotrophs and mycorrhizal fungi. There are also very
interesting and specific species for this region, some of
which are rare or endangered and have to be including in
Armenian Red List. New approaches to the investigation
and further theoretical study in this field are required. New
approaches to the investigation and further theoretical
study in this field are required.

Mongolia is an nation located between China and Siberia.
The climate is cold and dry. The steppe and the foreststeppe
occupy approx. 60% of the land. And the forest
occupy approx. 10% of the land. One hundred and eighty
eight mushroom specimens were collected and thirty three
species were identified. Mushrooms in steppe decompose
humus, dung and litter. Tricholoma monogolicum Imai is
the most famous species in Mongolian steppe. This species
grows on humus and forms fairy ring. Several species of
Agaricus are common in the steppe. The forest vegetation
consists Pinus, Larix, Betula, Populus and other trees.
There are many species of mushroom (Lentinus, Amanita,
Suillus, Russula, Polyporus, etc.) in the forest. Most of
them are similar to European and northern Japanese
species.

A joint private/USA government research team is tracking
fungal species richness in montane Oregon Douglas-fir
forests in two different 1998-2003 studies. Target species
include all 'epi-ecto' basidiomycetes + 40 other non-ecto
species flagged in the US federal Northwest Forest Plan. A
chronosequence study incorporates replicate 200 m 2
permanent strip transects in 25-, 55-, and 150-year old
stands sampled every 2 weeks during fall & spring fruiting
seasons. The density management study comprises adjacent
65-year old stands thinned in 1999 following 5 different
regimes: untreated (^450 trees/ha), thinned (3 stands with
^300, ^200, or ^100 residual trees/ha), or regeneration-cut
(0 residual trees/ha). During the first 4 years, 280 (chrono)
and 211 (density) target species have been identified from a
total of 4,100 collections and 515 total (322 target) species.
Agaricales comprise ^70%, Russulales ^20%, Gomphales
^5%, Boletales ^3%, and Cantharellales 1.5% of the target
species total. Cortinariaceae comprise ^84% of the
Agaricales; Cortinarius, Inocybe, Russula and
Phaeocollybia represent the most species-rich target
genera. After thinning, density study post/pre-treatment
stand species richness ratios were significantly depressed
only in the two most heavily thinned stands. Absence of
modern PNW monographs has dictated frequent
identification re-evaluation and led to development of
