We present a revised molecular phylogeny of higher
Basidiomycota
focusing on
Lepidostromataceae
based on the large subunit (28S) of the nuclear ribosomal rDNA (nuLSU), with additionl data from the translation elongation factor 1 alpha 1 (TEF1) and the RNA polymerase II second largest subunit (
RPB2
) genes. Our results suggest that
Lepidostromataceae
is best recognized in a separate order,
Lepidostromatales
ordo novum, within subclass
Agaricomycetidae
. Furthermore, the internal topology of
Lepidostromataceae
, correlating with thallus features, indicates that three genera, instead of a single genus, should be recognized. We therefore introduce the genera
Ertzia
genus novum and
Sulzbacheromyces
genus novum for
Lepidostroma akagerae
and
L. caatingae
, respectively. In addition, the new species
L. winklerianum
spec. nova is described for Mexican material previously identified as
L. calocerum
. The photobionts of
Sulzbacheromyces
and
Lepidostroma
were identified using molecular data of the large subunit of the ribulose 1,5-bisphosphate carboxylase/oxygenase (rbcL) gene, revealing a possibly undescribed genus in
Trebouxiophyceae
and the first report of lichenization for the genus
Bracteacoccus
in
Chlorophyceae
.
