Scytinium aragonii (Otálora) Otálora, P.M. Jørg. & Wedin

A recently described species from the S. lichenoides group (Otálora et al. 2008), characterized by flat horizontal lobes with crenate margins, the absence of isidia and the absence of deeply divided lobe ends. It is associated with well-preserved forests from lowlands to mountains where it grows on various mossy substrates, mainly tree bases. It also occurs among bryophytes on calcareous rocks and grasslands in the subalpine belt. In Europe, the species is widely distributed, but only locally abundant. There is a single historical specimen from the area of the Czech Republic (hillside of Hradisko in Znojmo) deposited in the Stockholm herbarium [] published in the exsiccate F. Petrak: Flora Bohemiae et Moraviae exs. n. 36 as Leptogium atrocaeruleum (leg. A. Oborny 1919, det. M. Otálora 2005). Recently it was recorded near Vřesová studánka in the Hrubý Jeseník Mts, in Štramberk and Podyjí National Park.
