River floodplain forests become extremely endangered in
last century and there are only scarce data on fungi of those
habitats. Field research on biodiversity of macrofungi in
two Danube islands, Sihot' and Sedláckov ostrov (city of
Bratislava) resulted in 211 species of Ascomycota and
Basidiomycota. Following taxa recorded during our
research are, according to the 3 rd edition of the Red List of
Slovak fungi, endangered: Ceriporia purpurea, Crepidotus
crocophyllus, Hypoxylon ticinense, Hyphodontia latitans,
Marasmius minutus, Ossicaulis lignatilis, Oxyporus
latemarginatus, Oxyporus philadelphi, Phlebia ryvardenii,
Rhodotus palmatus, Scutellinia legaliae, Scutellinia
sinensis, Spongipellis fractipes, Trichophaea variornata,
Trichophaeopsis bicuspis.

Blast disease, caused by Pyricularia grisea (teleomorph:
Magnaporthe grisea), represents the main threat to rice
crop. Blast pathogen population is divided into races, or
lineages, defined according to virulence spectrum on
differential rice cultivars; unfortunately, pathogenicity of
races identified in a country cannot be compared with that
of races in other countries, and in vivo screening
procedures are both complex and time-consuming. Italian
lineages have been only partially investigated, and a lot of
work is still needed as many (125) rice cultivars are grown
in Italy. A survey on a collection of P. grisea isolates,
currently in progress in our laboratories, is the first step to
characterise the Italian population. To date 103 strains have
been isolated, and are available for further analysis. In
order to characterise fungal isolates different methods
(greenhouse and molecular screening, in vitro assays)
could be used. An in vitro test was set up using partially
purified elicitors, instead of viable pathogen, and rice calli.
Suspension cultures of two rice cultivars (Gigante Vercelli
and Maratelli, resistant and susceptible to blast,
respectively) were used. In all cases a sharp rise of

hydrogen peroxide production was found soon after elicitor
addition. Interestingly, both control and elicited rates were
3 to 5-fold higher in the tolerant cultivar than in the
susceptible one, thus strengthening the possibility to use
this model to simulate in vivo infection.

In recent years, in Portugal, the harvest of wild edible
mushrooms has intensified greatly motivated by
commercial valorisation of this resource in the international
markets. The reduction of the mycological patrimony, and
biodiversity in general, is mentioned as the main
consequence of this process. The absence of regulation that
discipline the harvest and commercialisation of wild edible
mushrooms, as well as the inexistence of a global strategy
that promotes the conservation, management and
sustainable use of the fungus species and its habitat, are
considered as the main factors that contribute to this
situation. In this area, representatives of several entities
under the coordination of the Instituto da Conservação da
Natureza (Nature Conservation Institute) elaborated a
proposal of intervention that created guidelines and
indispensable measures to conserve and regulate the
mycological resources. Among the several measures,
suggested are highlighted: urgent regulation of the harvest,
reception, concentration and commercialisation of wild
edible mushrooms; creation of a good practices code;
implementation of measures to promote the knowledge on
portuguese fungal diversity and monotorising of particular
interesting species; promotion of training courses,
sensibilisation and environmental education which
emphasize the ecological and economical importance of
fungi. The present work intends, in a summary form, to
promote the main aspects that resulted from this initiative.
