Katzenohr

Clitopilus passeckerianus is a white-rot agaric fungus in the family Entolomataceae notable for its role as a natural producer of pleuromutilin, a diterpenoid antibiotic compound that serves as the biosynthetic precursor for the veterinary and human antibiotic drugs tiamulin and valnemulin, used to treat Mycoplasma infections in livestock. First described from European woodland habitats, the species produces the characteristic Clitopilus fruiting body: a pale, whitish cap with decurrent, crowded gills becoming pinkish at maturity from angular spores, and a farinaceous odor. Its antibiotic-producing capacity makes C. passeckerianus of significant pharmaceutical interest, and biosynthetic studies of pleuromutilin production have informed synthetic chemistry approaches to antibiotic development. The species inhabits temperate deciduous woodland floors in Europe, fruiting in autumn among leaf litter. Discovery of its pleuromutilin biosynthetic pathway has opened avenues for heterologous expression and semi-synthetic modification aimed at developing novel antibiotics to counter antibiotic-resistant bacterial pathogens.

Kreidiger Mehlpilz

Clitopilus scyphoides is an agaric fungus in the family Entolomataceae found in temperate European woodlands and grassland habitats. The species epithet scyphoides refers to a cup- or goblet-like form ('scyphus' meaning cup in Latin), likely describing the mature cap shape which becomes deeply depressed to funnel-shaped at maturity. Like other Clitopilus species, it produces white to pale cap surfaces, crowded decurrent gills that develop a pinkish tinge from the angular spores as they mature, and typically exhibits a mealy or farinaceous odor. It fruits in autumn in woodland clearings, beech and oak woodland floors, and occasionally in grassy habitats. The Clitopilus genus contains around a dozen recognized European species, some of which resemble the edible sweetbread mushroom C. prunulus. Molecular and morphological studies continue to clarify species boundaries and relationships within the genus. C. scyphoides contributes to the decomposer fungal community in its habitats, processing leaf litter and soil organic matter within temperate European forest and grassland ecosystems.
