McCune, B./ Martin, E.P./ Wang, L.S. 2003: Five New Species of Hypogymnia with Rimmed Holes from the Chinese Himalayas. - The Bryologist106(2): 226-234. [RLL Suppl.] Keywords: HYPOGYMNIA/ NEW SPECIES/ RIMMED HOLES/ CHINESE HIMALAYAS
Abstract: Five new species are described from the group of Hypogymnia with rimmed holes on the lower surface: H. bulbosa, H. congesta, H. diffractaica, H. laxa, and H. pseudocyphellata. All species in this group are restricted to the Himalayan region, primarily in southwestern China. Four other species in this group have previously been described: H. hengduanensis, H. kangdingensis, H. macrospora, and H. subvittata. Hypogymnia kangdingensis is synonymized with H. hengduanensis and Hypogymnia subvittata is synonymized with H. macrospora. Virensic acid (in H. congesta) and norbarbatic (4'-O-demethylbarbatic acid) are major lichen substances previously unreported from Hypogymnia.
