A new species of Clandestinotrema ( Ascomycota : Ostropales : Graphidaceae ) from montane cloud forest in the Venezuelan Andes
Revision of lichen herbarium specimens at DUKE revealed a species of thelotremoid Graphidaceae new to science. Clandestinotrema carbonera sp. nov. is characterized by an olive-green thallus, dense cortex, the absence of a columella, ascospores 15–24 × 5.5–8.0 μm with 3–5 transverse septa (occasional...

| description | Revision of lichen herbarium specimens at DUKE revealed a species of thelotremoid
Graphidaceae new to science. Clandestinotrema carbonera sp. nov. is characterized
by an olive-green thallus, dense cortex, the absence of a columella, ascospores 15–24 ×
5.5–8.0 μm with 3–5 transverse septa (occasionally submuriform), and the presence of
hypostictic acid as a major substance. At present the species is known only from the type
locality, an area of montane cloud forest near Mérida, Venezuela. Interestingly, this species
appears to have been discussed in the literature once before, as an unnamed ‘Thelotrema
sp.’ which in the 1970s provided the first instance of hypostictic acid isolated from a lichen.
The previous report of C. leucomelaenum from the same locality is shown to actually
represent C. pauperius. |
