Torrubiella dimorpha, a new species of spider parasite from Taiwan

Torrubiella dimorpha sp. nov. on an infected spider from Taiwan is described and illustrated. It is characterized by producing perithecia on an orange white, pulvinate, lanose mycelial mat covering the host. The anamorph, Gibellula dimorpha sp. nov., produces gibelluloid and granulomoid synanamorphs on aspergillate, distinctly roughened or warty conidiophores, or sometimes produces both synanamorphs on the same aspergillate vesicle. The differences between T. dimorpha and the closely related T. globosa, T. globoso-stipitata, T. arachnophila, T. ratticaudata and T. clavata are briefly discussed.
