MycoKeys 5: 1–30. doi: 10.3897/mycokeys.5.3342 Abstract Descriptions are presented for the seven known Bulbothrix (Parmeliaceae, Lichenized Fungi) species with salazinic acid in the medulla and without vegetative propagules. Bulbothrix continua, previously consid- ered as a synonym of B. hypocraea, is recognized as independent species. The current delimitations are confirmed for B. enormis, B. hypocraea, B. meizospora, B. linteolocarpa, B. sensibilis, and B. setschwanensis. New characteriscs and range extensions are provided. Key words Parmeliaceae, Parmelinella, norstictic acid, bulbate cilia Introduction The genus Bulbothrix Hale was proposed for the group of species called Parmelia Se- ries Bicornutae (Lynge) Hale & Kurokawa (Hale 1974). This group is characterized by small, laciniate and usually adnate thalli, bulbate marginal cilia, an upper cortex con- taining atranorin, with pored epicortex, without pseudocyphellae, with isolichenan in the cell walls, simple to branched cilia and rhizinae, smooth to coronate apothecia, hya- line unicellular ellipsoid to bicornute ascospores 5.0−21.0 × 4.0−12.0 µm, and bacilli- form to bifusiform conidia 5.0−10.0× 0.5− 1.0 µm (Hale 1976a, Elix 1993, Elix 1994).
