In the present paper, ten lichen species from Xizang are reported. Three of them
are new species and three new infraspecific taxa. One species and one variety are
made as new combinations. The apothecium of Lethariella cashmeriana Krog is described for the first time.
This paper also deals with nomenclatural problems of certain species. The authors
found that the specific epithets of Gyrophora hypococcina Jatta (A. Zahlbruckner,
1927, 1934) and G. hypocrocina Jatta (A. Zahlbruckner, 1930) were either orthographic
or typographic errors for G. hypococcinea Jatta (1902) (original spelling). According
to the Article 73:1 of the International Co de of Botanical Nomenclature [Leningrad
Code (1978)],. the epithet (hypococcinea) must be retained and the name Umbilicaria
hypococcinea (Jatta) Llano must, therefore be used substituting for U. hypococcina
(Jatta) Llano (1950; Lu, 1959).
The authors wish to express their sincere appreciation to Prof. T Ahti and Dr.O. Vitikainen (H) and Dr. Roland Moberg (UPS) for the loan of type specimens.
