A new species of hypogymnia and a new record in the lichen family parmeliaceae (ascomycota) from Sikkim, India

摘要

The lichen flora of eastern Himalayan region is renowned for its diversity (K. Singh Sinha 1994; K. Singh, 1999; Sinha, 1999). In a continuation of this study we are now describing a further new species from Sikkim. Throughout the present work chemical constituents were identified by thin layer chromatography (Culberson 1972; Culberson Johnson 1982; Elix & Ernst-Russell 1993), high performance liquid chromatography (Feige et al. 1993; Elix & Wardlaw 2002) and comparison with authentic samples.
