Slo.: podvihana kolesnica - syn.: Clitocybe flaccida (Sowerby) P. Kumm., Clitocybe inversa (Scop.) Qul., Lepista flaccida (Sowerby) Pat., Clitocybe flaccida (Sowerby) P. Kumm., Clitocybe gilva (Fr.) Kumm., Lepista inversa (Scop.) Pat., Lepista gilva (Pers.) Pat., Paralepista gilva (Pers.) Raithelh., Omphalia flaccida (Sowerby) Qul., Omphalia inversa (Scop.) Qul. - Habitat: Old, calcareous alluvial terrace, mixed wood, Picea abies, Fagus sylvatica, Ostrya carpinifolia dominant trees; under large Picea abies canopies (total shade, no ground vegetation, protected from direct rain) but also on grassy wood edge (half open, partly sunny place, exposed to direct rain); locally flat terrain; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 415 m (1.360 feet), alpine phytogeographical region. Substratum: soil, rotten needles and other plant material. Comments: Paralepista flaccida is a common, very variable (look at the list of synonyms!) yet relatively easy to recognize fungus by its foxy-red-brown (when wet) to orange-ocher (when dry) color and by its fleshy, waxy appearance. It shares typical Lepista species habit but it is somewhat smaller than more frequent and better known Lepista nuda or Lepista nebularis. Gills are easy to separate from trama as in most Lepista species. The fungus was separate from Lepista genus and put into Paralepista genus only in the year 2012 based on DNA evidence. Before that various genus and species names had been used and long, long debates about its taxonomy took place. Growing in groups, many fruit bodies found; pileus diameter 2.8 - 6 cm; smell pleasant, partly mushroomy partly mealy; flesh watery, brittle; SP white with a slight orange-pink tint. Spores somewhat warty, subglobose. Dimensions: (4) 4.1 - 4.7 (5.1) x (3.2) 3.7 - 4.3 (4.5) microns; Q = 1 - 1.2 (1.3); N = 40; Me = 4.5 x 4 microns ; Qe = 1.1.
