%X Spores of Dolichomitriopsis diversiformis were planted on Knop medium and cultured in incubator,and the process of spore germination and protonema growth were illustrated and microphotographs were taken.The results are as follows:spores began to germinate in the 2nd day and over 90% of them germinated in the 6th day.Protonema system was composed of the chloronema and caulonema.The rhizoides were formed from the bud base and produced from the caulonema which were degenerated.Gametophore primordium occurred at the branch base of the chloronema or at the caulonema cells which have cross walls that are oblique to the filament axis.Rhizoides were produced from nearly any part of the gametophore.The germination type of its spore was bryum type.
