Capillary Thread Moss is one of the mosses that commonly grows on concrete surfaces. It is most noticeable when the green capsules emerge in the late winter. These turn chestnut red as they mature, often on bright red stems. Bryum capillare grows in clumps, bright green in winter when the moss is hydrated. As it dries out in the spring, the stems twist and turn reddish. Here it is a common species on our paved driveway, and our house roof, which is shingled in concrete tiles. A few years ago we removed the sheets of moss that were growing on the roof. In total 8 cubic yards of moss were added to the garden - a substantial input of organic matter!
Two biologists on a beautiful property armed with cameras, smart phones and a marginal knowledge of websites took up the challenge of documenting one species a day on that property. Join along! Posts and photographs by Leah Ramsay and David Fraser (unless otherwise stated; started January 1, 2014.
