NOTES

For a detailed description, see Culberson & Culberson (1981).

This species is characterized by the presence of dense rhizines on the lower surface, marginal cilia usually simple and less than 1 mm long, slim lobes, and the presence of protocetraric and salazinic acids. H. subnepalensis (holo-, US [ US]!) is morphologically identical but differs in containing fumarprotocetraric acid.

H. nepalensis is widely distributed in Asia, growing in the mountains of Yunnan, Nepal, India, Thailand and Java ( Culberson & Culberson 1981), and usually grows on shrubs and trees. Local people from northwestern Yunnan use this species as a medicine (raw material for antibiotics). We used specimens from the type locality in Nepal and the nearby region of China for an estimation of the phylogenetic position of the species ( Fig. 1 ). This phylogenetic analysis confirmed the monophyly of the species, providing a reference for its delimitation.

FIG. 1. — Phylogenetic tree generated from maximum likelihood (ML) analysis based on ITS sequence data. ML bootstrap support values greater than 70% and Bayesian posterior probabilities (PPs) greater than 0.95 are given above the nodes. New species are indicated in bold. “TYPE” refers to the sequences of types, “TOPO” for specimens that come from the type locality. Scale bar: 0.02 substitutions.
