Trapelia calyciformis is described from China as a new species. The lichen is characterized by its gray-white thallus, zeorine apothecium with black disc and cracked excipulum, narrow paraphyses branched near the tip, 8-spored asci, aseptate ascospores with one vacuole, and the presence of gyrophoric acid. The specimens examined were deposited in LCUF. A key to the species of Trapelia reported in China is presented.

Gyrophoric Acid

AbstractExamination of specimens of Peltigera didactyla, from Africa, Asia, Europe and North America revealed that this sorediate species includes three entities that can be separated on morphological characters. A new species, P. lambinonii, is described from East Africa, and a new combination P. didactyla var. extenuata, is proposed to accommodate morphs from mesic forest habitats in Asia, Europe and North America. Despite this taxonomic reduction, P. didactyla var. didactyla remains a ubiquitous taxon. The former two taxa often produce methyl gyrophorate, which can co-occur with traces of gyrophoric acid. These tridepsides were only rarely detected in var. didactyla; their occasional presence seems to be best explained by hybridization. The taxonomic and ecological significance of these substances is discussed.

A New Species

A new species of Ophthalmoblysis Scoble, 1995 from Mexico is described and illustrated: O. ibarrai Garzón-Orduña, sp.n. The species is known only from Los Tuxtlas (Veracruz, Mexico), and is distinguished by the shape and pattern of the hindwing eyespot. Unlike the eyespot of other species in Ophthalmoblysis, that of O. ibarrai has a smaller and not fully circular inner black disc. In addition, O. ibarrai can be distinguished from a similar, undescribed species from Costa Rica by the presence of a sclerotized extension at the tip of the male valva and by the shape of the cornutus in the vesica. Ophthalmoblysis ibarrai represents the northernmost member of the genus.

AbstractLecanactis rubra is described as new to science. It is characterized by having rounded to irregular or lirellate ascomata, relatively wide 3-septate ascospores and by the production of gyrophoric acid and an anthraquinone. The species is known only from the type locality in the deciduous dry forests in the western part of Madagascar.
