SMALL ECILIATE SPECIES OF PARMELIACEAE (ASCOMYCOTA) FROM “PARQUE ESTADUAL DA CANTAREIRA”, SÃO PAULO STATE, BRAZIL: THE GENUS HYPOTRACHYNA

We surveyed the genus Hypotrachyna in “Parque Estadual da Cantareira” (Cantareira State Park) and its surroundings and found 12 species. Its species are recognized as having foliose thalli with narrow laciniate to sublaciniate lobes, usually ≤ 1.0 cm wide, with typical dichotomously branching rhizines and eciliate margins. Some species have a thick marginal line with rhizines that can be confused with cilia. Their medullary chemical constituents are one of the most complex among Parmeliaceae, with many substances not yet identified. In this work we are presenting the first citation of Hypotrachyna everniiformis and Hypotrachyna cf. lividescens for the State of São Paulo, in addition to also presenting an identification key, descriptions, comments and illustrations for the species cited are provided.
