Tibouchina granulosa
(
Melastomataceae
),
Brazilian
glorytree
(Brazilian
common
name
–
quaresmeira),
a
common
tree
of
the
Atlantic
Forest
of
Brazil,
is
widely
used
as
an
ornamental
for
its
violet
or
pink
blossoms.
Little
is
known
about
fungal
diseases
affecting
this
species,
although
these
represent
a
known
limitation
for
its
cultivation
in
nurseries.
Among
these
there
is
a
foliage
blight
that
occurs
in
combination
with
distortion
of
branch
apices
and
die-back.
A
consistent
association
of
a
species
of
Pilidiella
with the diseased
tissues
was
observed.
The
fungus
was
isolated
in
pure
culture
and
based
on
its
morphology
and
DNA
phylogeny,
we conclude that it represents a new species, for which the name
Pilidiella tibouchinae
is
introduced
