Ardhachandra, a new genus of the Hyphomycetes
A dematiaceous Hyphomycete collected on Ixora leaf litter from India is described. The fungus produces two types of conidia: lenticular and selenoid, both typically bivalved with a germ slit, blastic, solitary, terminal on the conidiophore and its successive sympodial proliferations. It is conspecific with the Tanzanian collection of a fungus assigned by Pirozynski in 1972 to Rhinocladiella critaspora Matsushima and designated the holotype of a new species of Pseudobeltrania, P. selenoides, by de Hoog in 1977. Pseudobeltrania selenoides is made the type of a new genus Ardhachandra; Rhinocladiella critaspora Matsushima (= Pseudobeltrania critaspora (Matsushima) de Hoog) is transferred to Ardhachandra as A. critaspora (Matsushima) comb. nov.
