Paraisaria monticola A holotype BPI 634610 B fertile head C ascus D ascus apex E portion of ascospore F part spores. Notes. P. monticola is known to occur on adult Northern mole cricket, Neocurtilla hexadactyla (= Gryllotalpa hexadactyla , Orthoprtera, Gryllotalpidae ). Other pathogens of mole crickets, Gryllotalpidae include Beauveria gryllotalpidicola , Beauveria sinensis , Cordyceps neogryllotalpae , Ophiocordyceps gryllotalpae , Ophiocordyceps krachonicola , and Polycephalomycs albiramus , all of which are only known from east Asia. Lloyd (1920) reported C. gryllotalpae from a mole cricket collected in Louisiana, USA, but that specimen was immature, and bore only cylindrical immature stromata with no ascogenous tissue. Owing to the absence of microanatomical character data available for C. gryllotalpae , and the lack of genetic data available for either species, future studies could compare P. monticola to C. gryllotalpae by chemical means, focusing on paraisariamide content of the fungal endosclerotium. P. monticola is only known from the type collection.
