A NEW ENTOMOPATHOGENIC FUNGUS ON SPIDERS

In the present paper, Torrubiella dabieshanensis a new fungus species parasitic on spiders is reported, with its anamorph Gibellula dabieshanensis. Its perithecia are superficial or partly embedded,with yellow tip. Ascospores are undulately curve after discharge.Secondary ascospores are 9.4～15.1×0.7～1.2μm. Synnemata are single or in pair, white. Conidiophores are smooth, 27～44μm in length.Conidia are fusiform 3.2～4.0×1.1～1.8μm. Granulomanus -type Conidiophores are present as a synanamorph,Conidia are filiform,11.0～20.0×0.7～1.1μm.A key to species of Gibellula is provided.The type specimen is deposited in Research Center of Entomogenous Fungi,Anhui Agricultural University, Hefei,Anhui.
