Resumo(s)
In the study of the fungi associated to
Platypus cylindrus, several fungi were isolated
from the insect and its galleries in cork oak,
among which three species of Raffaelea. Morphological
and cultural characteristics, sensitivity
to cycloheximide and genetic variability had
been evaluated in a set of isolates of this genus.
On this basis R. ambrosiae and R. montetyi were
identified and a third taxon segregated witch
differs in morphological and molecular characteristics
from the previous ones. In this work we
present and discuss the parameters that allow
the identification of specimens of the three taxa.
The role that those ambrosia fungi can have in
the cork oak decline is also discussed taking
into account that Ophiostomatales fungi are
pathogens of great importance in trees, namely
in species of the genus Quercus.
