Observation 149870: Russula adusta (Pers.) Fr.

Code: Bot_758/2013_DSC8444

Habitat: Mixed forest, almost flat terrain, probably acid ground (Lycopodium agg.,Vaccinium myrtillus) on calcareous bedrock, humid place, in deep shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, elevation 960m (3.150 feet), alpine phytogeographical region.

Substratum: forest soil.

Place: Zadnja Trenta valley, south of the parking place at the end of the road in the Zadnja Trenta valley, East Julian Alps, Posočje, Slovenia EC

Comments: Truly not one of the beautifully colored Brittlegills. However, still fun to find it since it is almost always well hidden under fallen leaves and other ground litter usually in deep shade. A good example of ‘mimicry’. Growing in groups, several pilei, several almost totally covered by fallen beach leaves. Diameter up to 12 cm (5 inch); ; flesh brittle but quite strong; SP pale yellow-ochre, oac894; peeling of cuticle modest.
