location
Northeast slope of Mt. Kobariški Stol ridge, Èirèe place, south of village Žaga, East Julian Alps (Posoèje, Slovenia)notes Slo.: zlatolasa tintnica - Habitat: A small meadow in mixed forest, grazed grassland, near a sheep stable, in short grass, many sheep drops around, in reach of solitary Betula pendula and Picea abies roots, almost flat terrain, calcareous ground, quite sunny place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevations 440 m (1.450 feet), alpine phytogeographical region. - Substratum: soil. - Comments: Help appreciated! Determination uncertain. Expert opinions (Ref.:1. and 2.) disagree. Ref.1. considers C. auricomus much less robust, paler and not of so fasciculate growth. Could be C. disseminatus, but in this case the lack of velum remnants on pileus remains a secret. Ref.2. relies on description on Kees-Uljee`s page. The description there corresponds in general well to the observation. However, most of pictures on internet (including on Kees-Uljee`s page) definitely show much more gracile Habitus for C. auricomus. Unfortunately, cystidia has not been studied. Any idea? - Description: Growth fasciculate or a few together, over 150 fruitbodies present of all ages; pileus height up to 3.5 cm when still closed, diameter 4.5(6) cm when old and open, orange-brown when young, chestnut brown and shiny in the center when grown up, no velum remnants; stalk 4-6 mm diameter, 12(14) cm tall and white; SP black, caps disintegrated completely in a black mass with time; no distinct smell. - Spores smooth, red-brown with large apical pore. Dimensions: 10.5 (SD = 0.7) x 6.2 (SD = 0.4) micr., Q = 1.72 (SD = 0.10), n = 30. Motic B2-211A, magnification 1.000 x, oil, in water. - Ref.: (1) Personal communication with Mr. Anton Poler.
