Taxonomic notes

The species was described as Agaricus fenzlii Schulzer (Schulzer et al. 1866). First detailed revision was published by Singer (1979) under name Chamaeota fenzlii (Schulzer) Singer.

There is a very similar species in North America, Pluteus mammillatus (Longyear) Minnis, Sundb. & Methven (Minnis et al. 2006), originally described as Annularia mammillata Longyear (Longyear 1902), which differs from P. fenzlii only by white to greyish-red lamellar edge (yellow in P. fenzlii).

Why suggested for a Global Red List Assessment?

Pluteus fenzlii is a very rare fungus known only from several countries in Europe and Asia.

Habitat and Ecology

Grows in the forest-steppe and taiga zone, and taiga belt, in humid and swamped birch, and mixed forests, on birch windfall.

In Slovakia the species usually occurs in hilly areas with more or less natural broadleaved habitats, mostly thermophilic ones. Based on data from Poland, Slovakia and Hungary, the most frequent substrate in this part of Europe is Quercus cerris (5 localities), followed by Fagus sylvatica (2). Basidiomata were observed on fallen trunks (including their branches), both thin and medium thick (10-55 cm diam.), and branches separated from old living trees and lying on soil (about 20 cm diam.). The basidiomata grew either from decorticated wood or cracks in the bark, often at sites covered by mosses.
