Chaenothecopsis nigra Tibell

A non-lichenized calicioid fungus characterized by pale ascospores with contrasting dark septa. It occurs mainly in older moist montane and boreal forests, where it usually grows in association with algae on wood or bark of trees with acidic pH. It is relatively rarely reported from Europe and belongs to the lesser known representatives of the genus. In the Czech Republic, most localities are known from the Šumava Mountains. It has also been reported from the Český les Mts, Krkonoše Mts, Hrubý Jeseník Mts and Český ráj. Records come from a spruce bark or wood. In the Český ráj area (PR Bažantník) it was found on old oaks.
