Collection location: Bovec basin, East Julian Alps, Posočje, Slovenia [Click for map]
Habitat: slightly inside light, mixed, unmaintained forest edge with many shrubs; Picea abies, Fagus sylvatica, Corylus avellana, Prunus spinosa, Rubus sp. etc. present; near a small water stream; flat terrain; cretaceous clastic rock (flysh) bedrock with some limestone; humid place, mostly in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 460 m (1.500 feet), alpine phytogeographical region.
Place: Bovec basin, northeast of Mala vas, near a small stream, East Julian Alps, Posočje, Slovenia EC.
Comments: There exist four whitish species with very similar habit in the genus Tricholoma: Tricholoma album, Tricholoma columbetta, Tricholoma inamoenum and Tricholoma lascivum. Hence confusion and misidentifications are frequent. Also nomenclature history of these species is ‘difficult’. From this reason some experts consider published distribution ranges of these species as questionable. MycoBank (Ref.7) states: “Real distribution poorly known because of the taxonomic confusion with similar species”.
This find was at first (based on habit) recognized as Tricholoma inamoenum. However, measured spores were much too small for it. Their dimensions and particularly narrow spores (Q exceeding 1.6) speaks in favor of Tricholoma lascivum. Also other macro traits and habitat seems to fit reasonably well to this determination. Alternatives: Tricholoma album is a symbiont with Betula or Quercus, which were not present in the vicinity; Tricholoma columbetta is practically without odor (Ref. 2 and 3) while the find had strong, unpleasant smell on gas or chemistry; Tricholoma album and Tricholoma columbetta also have somewhat smaller spores then measured, while, Tricholoma inamoenum has significantly larger spores.
Description: Several fruit bodies present, some clustered; pilei diameter up to 3 – 7(8) cm; smell strong, unpleasant, on gas or some chemistry; taste not tested; SP abundant, white.
