LICHALP

Strigula jamesii (Swinscow) R.C. Harris

Syn.: Geisleria jamesii Swinscow

Lichenised.

Substrate: bark, living mosses

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a species differing from the similar S. affinis in the smaller perithecia (to c. 0.2 mm in diam.) and macroconidia, found on bark of broad-leaved trees, more rarely on mosses over calciferous substrata, in humid-shaded situations; widespread in Europe, but most common in the West, and also reported from North America.
