location
Mt. Mangart region, northeast ridge of Mt.Planja, 1.553 m, East Julian Alps (Posočje, Slovenia)notes Slo.: osmojena kolobarnica - Habitat: In mixed alpine forest, dominant Fagus sylvatica with some Picea abies and Abies alba; locally east, generally south oriented mountain slope, relatively warm place, calcareous bedrock however apparently at least to some extent acid soil (Vaccinium myrtillus abundant); mostly in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 2-4 deg C, elevation 1.470 m (4.800 feet), alpine phytogeographical region. - Substratum: forest soil under Fagus sylvatica. - Comments: Following the key of Tricholoma (Fries.1821) in Ref.:(3), p521 I come to Tricholoma ustale without problems. However, the color of the fruitbodies found seems too to be too bright and to have more yellow and less red as in most references. Not sure the determination is OK. - Growing scattered, about 5 - 6 fruitbodies; pileus diameter from 6 to 8.5 cm, stipe up to 8.5 cm long; taste mushroomy and moderately bitter and burning, unpleasant; smell not strong, on earth (?); flesh whitish, bruising slowly with time, particularly at the base of the stipe; SP white (oac909), pilei strongly slimy, the layer of the mucus more than 1 mm thick. - Spores smooth, elliptical. Dimensions: 7.1 (SD = 0.4) x 5.4 (SD = 0.3) μ, Q = 1.31 (SD = 0.08), n = 28.
