Abstract:

A revision is made of the genus Colysis from China and its adjacent regions on the
basis of field studies and herbarium observations. Nine species and one hybrid are recognized
based on the spore morphology, cytology and geographical distribution. Colysis elliptica is
divided into five varieties. Scale-like sporiangial paraphyses are found in sori of Colysis
wrightii for the first time.
