In Argentina, there are about 2,000,000 ha of grasslands
suitable for afforestation with fast growing non-native
conifers along the piedmont of the Patagonian Andes, and
ponderosa pine is the most widely planted species. Many of
this planting sites are under water stress conditions. The
aim of this study was to survey mycorrhizal species
richness and their distribution along the precipitation
gradient in ponderosa pine plantations in Patagonia. Eleven
plantations, four under a precipitation regime of 1000 mm
(humid plantations) and six under 400-600 mm (dry
plantations), were surveyed for two springs and two
autumns for hypogeous and epigeous fungi. Amphinema
byssoides was the most widely distributed species, found in
all plantations. The other species differed in their presence
according to the humidity gradient. Humid plantations
presented 9 different taxa, each plantation displaying a
species richness between 4 to 6. Hebeloma mesophaeum
was present in all of them, followed by Suillus luteus and
Rhizopogon rubescens. Dry plantations presented 5
different taxa, and each plantations displayed a species
richness between 1 to 4. S. luteus, H. mesophaeum and R.
rubescens were the most widely distributed. Data showed
that species richness was strongly dependent on
precipitation. The principal species, though, were the same,
but their relative occurrence varied in different conditions.

Modern social and economic conditions in Russia are
characterized by numerous negative factors and processes
which influence on biodiversity. Loss and destruction of
natural locations are the main danger for mycobiota
diversity. For long-term purposes of macromycetes
conservation ex situ specialized culture collections serve.
During the past ten years the main trend of development of
the Komarov Botanical Institute Basidiomycetes Culture
Collection - LE(BIN) has been considering as conservation
and maintaining of macromycetes cultures with emphasis
on preservation of macromycetes from reserved territories.
About 250 new macromycetes cultures were isolated
during field works in Russian reserves such as 'Nizhne-
Svirsky' (Leningrad region), 'Les na Vorskle' (Belgorod
region), Island Valaam (Karelia) and others. LE(BIN)
species representation was increased by new cultures from
genera Clavicorona, Collybia, Marasmiellus, Marasmius,
Mycena and Lentinellus. Strain diversity of Collybia,
Marasmiellus, Marasmius and Mycena was also increased
essentially. Considerable representation of biological
species of the genus Lentinellus is maintained in the
Collection. The genus Clavicorona is presented by six
strains of the typical species Clavicorona pyxidata.
Cultures of ectomycorrhizal fungi, rare species and ones
that were recommended for conservation in Russia are also
preserved in the Collection LE(BIN).

Tricholoma magnivelare (Pine Mushroom) and
Cantharellus formosus (Chanterelle) are commercially
important wild forest mushrooms in British Columbia.
Recently, research to integrate these mycological resources
into forest planning has been carried out. Productive Pine
Mushroom habitat throughout BC was characterized and
the common factor found was dry and nutrient poor soil. It
was then determined in north western and south central BC
that it is possible to protect and manage Pine Mushroom
habitat without an unacceptable impact on timber
harvesting because of the relatively small area of highly
productive Pine Mushroom habitat and low tree
productivity of this habitat. On Haida Gwaii, a study
determined that Chanterelle productivity on sites burned
prior to regeneration was greater than on similar sites with
no fire history. In British Columbia over 95% of the
forestland is publicly owned which creates challenging
policy and regulatory issues. A study of social and
economic potential of non-timber forest products (NTFPs)
on Haida Gwaii discussed many of the issues resulting
from the annual influx of mushroom pickers. A subsequent
study assessed how property rights could be used to
overcome concerns and enhance stewardship. Integrating
many of these findings and concerns, the Northern
Vancouver Island NTFP Demonstration Project is
researching how best to manage non-timber forest
resources in a way that is environmentally sustainable,
economically viable and socially equitable.
