Abstract
This study was focused on two species of lichen-forming fungi from Madagascan Region whose tax
-
onomy has been controversial over the years,
Cladonia mascarena
Nyl.
and
Heterodea madagascarea
Nyl. While some authors considered
C. mascarena
to belong to
Cladonia,
others place it in
Pycnothelia
Dufour. In this study three loci (ITS rDNA,
rpb2
and
ef1
α
) were used to determine the phylogenetic
placement of
C. mascarena
. Our results show that it belongs to
Pycnothelia
and the combination
Pyc
-
nothelia mascarena
(Nyl.) Nyl. is substantiated
. In addition,
a key to the genus
Pycnothelia
is provided.
The morphological study of new specimens of
Gymnoderma
coccocarpum
Nyl. and
H. madagascarea
concluded that
these taxa
belong to a same species, confirming the extension of
Gymnoderma
Nyl.
to Africa. The overlooked genus
Baeoderma
Vain.
is regarded as a synonym of
Gymnoderma,
and its
type species
Baeoderma madagascareum
(Nyl.) Vain.
is
referred to
G.
coccocarpum
.
