Rhizoidal tubers are newly found in Garckea flexuosa (Griff.) Marg. & Nork. and Ditrichum macrorhynchum Broth. Tubers of Garckea flexuosa are composed of 3-6 cells. Rhizoidal tubers of Ditrichum macrorhynchum are very similar to those of D. lineare recently reported by Matsui, Deguchi & Seppelt (1985).
