Lewinskya affinis Wood Bristle-moss

An autoicous, epiphytic, acrocarpous moss which forms loose tufts on willows and other trees with relatively smooth bark. It is quite variable in form and sometimes microscopic examination of stomata is necessary to confirm identification - Sam Bosanquet's article in British Wildlife (February, 2009) on the identfication of Orthotrichum species is recommended as an indispensable aid. It is the commonest bristle moss in Britain and it is found throughout Britain except in the highlands and extreme north of Scotland. It is widespread and abundant in Wales and it is one the commonest epiphytic mosses in West Glamorgan. Sporophyte capsules are common from spring to autumn. They are strongly furrowed when dry and the outer peristome has 8 pairs of reflexed teeth.

Formerly and better known as Orthotrichum affine.
