microsporus, M. wynnei f. carpathicus, Melanoleuca
polioleuca, Mycena zephirus, Panaeolus cintulus,
Psathyrella microrhiza and Tubaria autochthona were
recorded for the first time in Greece, while Ceratobasidium
cornigerum, Mycoaciella bispora, Myxarium laccatum and
Ramicola haustellaris represent first reports for the
respective genera in Greece. Of particular interest are
records of lignicolous species from Mediterranean
evergreen scrubs and frygana, i.e. Hyphodontia juniperi
and H. sambuci on Thymus capitatus; Peniophora lycii, P.
pithya and P. tamaricicola on Pistacia lentiscus;
Aleurodiscus dextrinoideocerussatus, Hyphodontia pruni,
Peniophora lycii, Steccherinum fimbriatum and S.
ochraceum on Genista acanthoclada; Aleurodiscus minor
and Lentinellus omphalodes on Cistus sp.; Gloeophyllum
abietinum, Perenniporia rosmarini and Peniophora piceae
on Juniperus phoenicea; and Dacrymyces lacrymalis and
Pluteus nanus f. nanus on Nerium oleander.

BIOTEC Culture Collection is a specialized collection
formally established in 1996 under the National Science
and Technology Development Agency (NSTDA). The
principle objective is to provide safe deposition of cultures
for researchers; to preserve and maintain microorganisms
isolated from Thailand for future use; and to manage strain
data information. Another major role is to supply cultures
and related information for an in-house screening
programme for drug discovery from microorganisms. The
collection comprises 10,000 isolates fungi from various
sources and habitats: insect fungi (1,618), aquatic
freshwater and marine habitats (1,324), rice blast fungi
(1,148), soil including leaf litter and humus (973), wooddecay
Xylariaceae and Basidiomycota (898), plant seeds
(389 strains), endophytic fungi (754), lichens (247) and
taxa from other sources (1,090). The collection also
includes bacteria and actinomycetes (1,789) and yeasts
(342). The preservation methods used are freezing at -80
°C, in a vapor phase of liquid nitrogen at -170 °C; freezedrying
and under liquid paraffin oil. The essential strain
data of cultures being maintained are used to create a
required database and produce the catalogue of cultures.

The Komarov Botanical Institute Basidiomycetes Culture
Collection - LE (BIN) maintains over 1000 strains of 428
species of aphyllophoroid, agaricoid and gasteromycetoid
macromycetes collected mainly in Russia and former
USSR. Conservation of Basidiomycetes diversity ex situ
with a special interest in rare and endangered species as
well as cultural maintenance of mushroom taxa with
biological activity, especially those could be used in
medicine and industry, is one of our primary goals.
Taxonomic verification of Basidiomycetes cultures
maintained in the culture collections is of great importance.
In the process of starting and transferring living cultures
error can be introduced in two ways. First, cultures can be
obtained from incorrectly identified basidiomata or the
identification has been done according to an out of date
classification. Recent studies on Flammulina and Pleurotus
species enable us to carry out taxonomic verification of LE
(BIN) cultures from these genera by mating study
according to the biological species concept. Second,
replacement of a Basidiomycetes culture with a a different
species, mainly from the group of imperfect fungi, can
occur during the strain isolation or subculturing. This often
happens in culturing of slowly growing and
ectomycorrhizal fungi. To veryfy a cultural strain's identity
and purity detailed studies of cultural characters, fruiting of
strains in culture and molecular analysis are being used in
the LE(BIN) Collection.

When P is deficient in soil solution, the critical root
parameter controlling its uptake is its surface area. Hyphae
of mycorrhizal fungi have the potential to greatly increase
the absorbing surface area of the root. Modified gridline
intersect method was employed for extracting hyphae from
the soil and quantifying length under field conditions in a
Benomyl treated and non treated soil with the following
three P levels: P 0,P 50 and P 400mgkg-1 soil as single
super phosphate. To asses the importance of mycorrhizal
hypha nutrient uptake model was used. Wettable powder of
the fungicide Benomyl was mixed thoroughly to 15 cm soil
depth at 500 kg ha-1. Treated plots were covered by paddy
straw for two weeks to avoid excessive heating. There was
