Dissotocum, Pintermedium, P. middletonii, P. myriotylum, P. periplocum, P. rostratum and P. torulosum. Among them, P. aquatile is a new record in China: P. myriotylum is the first isolation from water in the world. All the species included in this paper excep: P. middletonii are isolated for the first time from water in China, and six of them are described and illustrated. The strains identified as P. middletonii and P. rostratum, which exhibit no difference from those which were reported from other habitats before, are listed and discussed.
