GRONER, U. (2010). Calicioid lichens and fungi in the Muota Valley, central Switzerland: high species diversity in a small area. Candollea 65: 377–391. In English, English and French abstracts.

An inventory of the calicioid lichens and fungi of the Bödmeren Forest region in the Muota Valley, central Switzerland, produced no less than 51 lichenized and non-lichenized taxa on bark and wood. This mainly subalpine spruce forest in the Prealps hosts the most diverse calicioid flora in Switzerland today and a similarly rich flora from a comparably small area is unknown from neighbouring countries. Calicium denigratum (Vain.) Tibell and Chaenothecopsis oregana Rikkinen are new to Switzerland. Calicium adaequatum Nyl., Chaenothecopsis tasmanica Tibell and Chaenothecopsis vainioana (Nádv.) Tibell are also reported for the first time from this region. Chaenotheca chrysocephala (Ach.) Th. Fr., Calicium viride Pers., Chaenotheca trichialis (Ach.) Th. Fr. and Microcalicium disseminatum (Ach.) Vain. are the most frequent species, the majority of the other taxa are uncommon or rare. The diversity of the calicioid (and other) species is due to several favourable conditions, such as the presence of old-growth forest stands and the occurrence of standing dead trees. More than 40% of the recorded lichenized calicioid taxa are threatened; the state of the poorly known non-lichenized calicioids is undetermined as they were not evaluated in the “Red List”.
