Lenzitopsis (Thelephorales, Basidiomycota), typified by Lenzitopsis oxycedri, was monotypic
before we described the second species of this genus, Lenzitopsis daii in this study. L. daii
resembles L. oxycedri in producing lenzitoid hymenophore as well as brown hyphae and
echinulate spores, but it differs from the type species by its annual basidiocarps, amyloid
spores and growth exclusively on Juniperus chinensis (Cupressaceae). In the phylogenetic
perspective inferred with nuclear large subunit ribosomal DNA sequences, the two species
were separated from each other and formed a strongly supported clade in the Thelephorales.
The two Lenzitopsis species showed a more than 5% difference in internal transcribed
spacer sequences. Lenzitopsis species are wood-decaying fungi, and this is the
second genus of the order where mycorrhizal life style is unknown, besides of Amaurodon.
