Two species of Cleveaceae; Peltolepis quadrata and Sauteria japonica were found in Mt. Senjo, Nagano Prefecture, central Japan. Both species have been known from only a single locality in Japan; the former from Rishiri Island, and the latter from Mt. Yatsu. Information on morphology, taxonomy, and ecology of these species has been limited for Japanese plants, new morphological and ecological notes are given.

Bucklandiella vulcanicola (Frisvoll & Deguchi) Bednarek-Ochyra & Ochyra has unique endogenous gemmae. The plants of this species, collected from Izu-Oshima Island, Japan, are shown to produce a different type of gemmae. These gemmae are produced on short stalks arising from upper dorsal surfaces of specialized leaves, and they are filamentous and composed of 3-7 cells.

Nematode galls were found from hepatic species, Lejeunea tuberculosa Steph. collected at Doi Inthanon, Chiang Mai Co., northern Thailand. The species grew among a small patch of Dicranoloma braunii (Mull. Hall. ex Dozy & Molk.) Paris on a shrub trunk in a well preserved upper montane forest developing at 1700m alt. The galls were formed with a number of tightly gathered abnormal leaves at the top of each shoot. Two nematode species are found within a single gall; one is filamentous without distinct ornamentation and large in number, while the other is much thicker with curved tails, vent, and ring-like ornamentation at the terminal position. The latter were found only in a small number. Eggs were also found in the galls and, judging from their size, they are eggs of the filamentous nematodes. The filamentous one seems to be the same species reported by Kitagawa (1974) and Asthana & Srivastava (1993). Since the thicker ones have curved tails, they might not be a gall-forming species but a usual dweller on bryophyte patches (Glime 2007).
