The author considers the present trends in mycological research, espec
ially dealing with taxonomy, systematics and phylogeny. ''Traditional'
' methods seem clearly regressing if compared with molecular methodolo
gies, which contribution is undeniable but which limits are still rath
er poorly known. On the other hand, the present taxonomical knowledge
of the fungal kingdom is very weak and the ecological context very dis
quieting. Therefore, it is necessary to develop descriptive studies in
the field, before the unknown species become vanished, especially in
The Tropics. The purely scientifical argument concerning the basic kno
wledge of biodiversity can be strengthened with some applied examples
(conservation of species and ecosystems bound to a functional but also
taxonomical knowledge; uses of fungi as allies in different topics -b
io-indication, pharmacology, biological control, bio-technologies, etc
.). The necessity for a balanced co-operation between ''traditional''
and ''modern'' trends of mycology is strongly emphasized.
