NOTES

For a detailed description, see Jiang & Wei (1989).

H. subsorocheila can be distinguished by its pustular upper surface, forming granulose soralia, which are concolorous with the thallus or turning blackish and spread from the tip to the centre of the lobes; the lobes are usually wide and short ( Fig. 5C ). Salazinic acid is absent. Two other sorediate species, H. himalayana and H. sorocheila , also have soralia, but the soralia are powdery and white in these species and grow only on the lower surface of the lobe tips; the lobes are slim and anchor-shaped, and they contain salazinic acid. Furthermore, our phylogenetic analysis ( Fig. 1 ) revealed that H. subsorocheila (GenBank Nos: MN335193, MN335194) was not clustered with H. sorocheila or H. himalayana .

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.
