Bryocrumia vivicolor sporophytes perichaetial leaves rheophyte Yunnan Bryophytes


Based on recent collections made in Yunnan Province, China, the sporophytes of Bryocrumia vivicolor were discovered for the first time for this species. With typical hypnoid peristome teeth, short operculum, and slightly collenchymatous exothecial cell walls, the capsule of B. vivicolor conforms to the basic definition of Hypnaceae, and this monospecific genus is deemed to belong in Hypnoideae according to current circumscription of the subfamily. Although the identity of Bryocrumia seems to be well-supported morphologically by the additional features such as the bluntly obtuse apex of perichaetial leaves and the deciduous annulus consisting of irregular-shaped cells in 1–2 rows, future molecular study could provide useful insights in understanding the distribution of this rarely collected yet geographically widespread species.
