Flavocetraria

Kapuzenflechte ( Flavocetraria cucullata )

The genus Flavocetraria includes three types of lichen shrub with pale yellow cloth that were originally counted to the genus Cetraria. You are arctic - alpine distributed, but are also found sporadically in the southern hemisphere. Two species, the Kapuzenflechte and Schneeflechte, also occur in Central Europe.

The lichens of the genus Flavocetraria are ground inhabiting shrub lichen. They grow upright with flat or tubed, sparsely branched lobes. Your photobionts belong to the genus Trebouxia algae. On the underside of the lobes are Pseudocyphellen. The species of the genus have brown, terminal apothecia, but you will seldom occur. The ascospores are unicellular and ellipsoidal. The marginal, black pycnidia produce small, dumbbell-shaped pycnospores. All species contain, inter alia, usnic acid.

Systematics and etymology

Kärnefelt and Thell presented in 1994 pale yellowish, the Icelandic moss resembling lichen in the distinct genus Flavocetraria. Type species is the Kapuzenflechte Flavocetraria cucullata. The name derives from the Latin word Flavocetraria flavus = yellow, and the genus Cetraria from. The name comes from the Latin word Cetraria caetra = smaller, lighter leather shield and refers to the fact that the bearing portions of the Icelandic moss are often shiny brown.
