Polycytella hominis gen. et sp. nov., a cause of human pale grain mycetoma.

A hyphomycete isolated from a pale-grain eumycetoma in an indian male patient is described as a species of a new form-genus, Polycytella hominis. The fungus is characterized by elongate multiseptate conidia in which only the apical compartment becomes thick-walled and retains viable cytoplasm. The appearance of P. hominis in the host tissues is described and compared with other pale-grain eumycetomas.
