Habitat: mixed wood, Picea abies and Fagus sylvatica dominant trees; locally almost flat terrain, bottom of the valley; calcareous ground; almost in shade; partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, elevation 820 m (2.700 feet), alpine phytogeographical region.

Comments: Tricholomopsis rutilans can hardly be confused with other species in the field. Beautifully yellow-reddish colored mushroom has abundant and large (up to 140 microns long) cheilocystidia, which can be seen even without microscope with any magnifying glass. The mushroom is generally quite common although not in the Trenta valley. A single fruitbody has been found. Smell and taste mild, indistinct; SP white.
