Small Hairy Screw-moss up a tree in Morristion Hospital

Small Hairy Screw-moss on Ohio Buckeye
Among the collection of trees in Morriston Hospital car park are two beautiful Black Walnut (Juglans nigra) trees and a moss-clad specimen of Ohio Buckeye (Aesculus glabra). Among the epiphytes growing on the latter were some nice cushions of Small Hairy Screw-moss (Syntrichia laevipila) along with a surprising quantity of Sessile Grimmia (Schistidium apocarpum), a species more characteristic of base-rich, siliceous rocks.
