It is generally believed by the scientific community that the
culture collections and herbaria are managed by trained
taxonomists who ensure the purity and authenticity of the
research materials prior to their supply. The quality of
services provided by such centres are generally of high
standard vis-à-vis those which lack the expertise.
Unfortunately, the taxonomists have to prove, time and
again, that their science is not old-fashioned and
intellectually dull but is the bed rock of all biological
research. Nevertheless, based on an appeal by a group of
taxonomists and with scientific reproducibility gathering
momentum, the editors of some reputed microbiology
journals have made it a mandatory requirement of
providing deposit details of working materials with
recognized culture collection centres or herbaria before any
paper is accepted for publication. We propose to discuss a
few interesting cases encountered with our centre relevant
to the points mentioned above and the options available
with the editors of journals for the strict compliance of
their latest guidelines.

The base of our investigation is an assumption about
affection of mycoflora structure by air pollution. The
occurence of the ectomycorrhizal, saprobic and parazitic
fungi was observed during three years at three beech
stands. Conditions for fungi growth were nerly compatible
on all stands, difference was only in degree of pollution
pressure. Number of fungal species and fruitbodies,
together with other characteristics of investigated stands
(health condition of trees, soil analysis, climatic
conditions), were analysed using mathematic-statistical
methods. In this way factors affecting a fungi production in
beech forest exposing to various pollution pressure was
choosen. An important result of this work is a possibility to
use the macromycetes for bioindication of various polluted
beech forest stands: - The share of mycorrhizal species
significantly decreases and the share of saprobic ones
significantly increases at beech stands under pollution
pressure; - The mycorrhizal species of genus Cortinarius,
Cantharellus, Hydnum, Ramaria and Tricholoma are
practically missing at these stands; - At the same time the
number of saprobic species of genus Clitocybe, Collybia,
Coprinus and Lepista expressively increases.

Refuges of polypore fungi which are located near
geothermal waters of Pribaikalia, are distinguished by the
degree of local heat-provision and the history of site
evolution. Four types of refuges in the mountainous areas
of Pribaikalia have been indentified. The fourth type
includes sites in which all the nemoral complexes have
have been preserved and concentrated in the warmer steppe
landscapes. The site near Selenga river which includes
broad-leaf associations of relics nemoral Japanese Elm
(Pleshanov, Penzina, 1996). Species composition of the
first zone is characterized by xerophylies: Gloeophyllum
sepiarium (Wulf.:Fr.) Karst., G. trabeum (Pers.:Fr.) Murr.,
Trametes ochracea (Pers.) Gilbn.& Ryv. It is a zone of
direct influence of hot springs. It is necessary to consider
this biotope as an extreme for wood attaching associations -
the wood is occupied by fungi for a short period,
hypothetically, in the winter, when the spring water is
natually cooler. The biotopes of the Selenga floodplain,
which belong to the second zone of refuges, are
distinguished by the maximum size of the fruiting bodies of
the perennial polypore fungi in Pribaikalia, as well as a
wealth of species diversity and structure of mycocommunity.
Striking representatives of the thermophylic
complex, which have been discovered in relict Elm forest,
are Trametes conchifer (Schw.:Fr.) Pil. on fallen branches
of Elm, and Inonotus hispidus (Bul.:Fr.) Karst., living on
the trunks of live Elm trees.

Ciferri (1929a) and Murrill (1915) reported 17 species of
polypores in 13 genera from the Dominican Republic
according to modern taxonomy. We surveyed polypores in
the Dominican Republic beginning in 1996. Decock &
Ryvarden (2000) described Perenniporia cremeopora and
Lodge, Ryvarden & Perdomo (2001) described Antrodia
aurantia from the DR. Minter et al. (2001) listed 80 of our
new records. In addition to the published records noted
above, we report here six new species records for the
Greater Antilles: Antrodiella parasitica, Chaetoporellus
latitans, Gloeoporus dichrous, Inonotus cf. micantissimus,
