The voucher specimens of the mosses （Leucodontaceae and Pterobryaceae） reported by Suzuki & Iwatsuki （2012, 2013） and Suzuki （2017） as new to Japan were re-examined. As a result,（1） Antitrichia curtipendula, （2） Jaegerina scariosa, （3） Nogopterium （≡ Pterogonium） gracile, and （4） Nogopterium （≡Pterogonium） coreense were found to be excluded from Japanese flora. These reports were based on misidentification of （1） Forsstroemia sp., （2） Isothecium subdiversiforme, （3） Forsstroemia neckeroides, and （4） Hypnum leptothallum, respectively. The plant as Nogopterium tsinlingense from Japan was Pterogoniadelphus （≡ Felipponea） esquirolii. Nogopterium tenellum, described as a new species, was newly synonymized with Homomallium japonicoaduncum. The proposal of recombination for three Leucodon species, i.e., L. brachypus, L. julaceus, and L. pendulus to the genus Pterogoniadelphus was not supported by leaf morphologies between the two genera and also molecular phylogenetic analyses. Thus, the three species should be retained in the genus Leucodon.

We reported on large winter buds newly found in Sandea japonica （≡Conocephalum japonicum）. They are similar in structure to normal propagules of the species bearing at the tip of thalli in winter season, but differ in size and shape as well as presence of elongated rhizoids on the ventral surface and thicker stipes which connect the buds to the thalli. These large winter buds continue to grow when they germinate in the following spring and thus are quite comparable to those of Conocephalum conicum complex
