‘Sporidesmium’ lichenicola sp. nov. is described from the decaying thallus of an unidentified Leptogium species growing on unidentified tree bark from the Guaramacal National Park in Bocono´ , Ta´chira, in western Venezuela. This is only the second lichenicolous species to be described under this generic name, and differences from that species and similar species in Sporidesmium s. lat. are discussed. A more precise generic placement will have to await a molecularly based taxonomy of the genus. The original material comes from a mycologically little explored region of the country, and brief information on previous mycological (including lichenological) studies in the area is provided for the first time in English. The new combination S. sinense (syn. Repetophragma sinense) also is made. Key words: anamorphic ascomycetes, conidial fungi, dematiaceous hyphomycete, lichens, tropical fungi
