Abstract: Spore morphology of 14 species in the genus Dryoathyrium and one in the genus Luna- thyrium from China was investigated under light microscope (LM) and scanning electron microscope  (SEM). The spores are monolete, bilaterally symmetric, elliptic in polar view, and semiorbicular or reniform in equatorial view. According to the surface ornamentation of the perine, the spores in  Dryoathyrium can be divided into three types. Type I is characterized by having lophate processes on the perine which are connected and reticulate or ornate. Three species, D. chinese, D. core- anum and D. pterorachis, have this type of spores. Type Ⅱ is characterized by having curved-lo- bate, lobate or tuberculate processes on the pefine. Eight species, D. boryanum, D. confusum,  D. edentulum, D. henryi, D. okuboanum, D. stenopteron, D. setigerum and D. viridifrons, have this type of spores. Type Ⅲ is characterized by having spine-like, irregularly baculate or pa- pilla-like processes on the perine. Three species, D. erectum, D. falcatipinnulum and D. uni- furcatum, have this type of spores. The spore morphology of Lunathyrium ningshenense is very simi- lar to that of D. coreanum, supporting the treatment of reducing the former to the synonymy of the latter.Decontaminated thianthrene disproportion.
