location
Lower Trenta valley, between villages Soča and Trenta, right bank of river Soča; next to the trail from the main road Bovec-Vršič to farmhouse Skokar, Trenta 2, East Julian Alps (Posočje, Slovenia)notes Slo.: noroglavka, svinjski goban - Boletus luridus Schaeff. : Fr., Leccinum luridum (Schaeff.) Gray, Tubiporus luridus var. rubriceps Maire - Habitat: Steep mountain slope, east aspect; mixed wood, Fagus sylvatica, Ostrya carpinifolia and Picea abies dominant trees; under Fagus or eventually Ostrya; in shade; calcareous, skeletal ground; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 535 m (1.750 feet), alpine phytogeographical region. - Substratum: soil. - Comments: Suillellus luridus, formerly named Boletus luridus, is with little doubts the commonest bolete in Trenta valley. The species is very beautiful but also very variable. I have photographed it many times. This find seemed at the beginning something special since both pilei found were all in yellowish tones almost without reddish hues as usual in my region. Also bruising was relatively weak compared to some other finds, which bruised immediately to dark, sometimes really wild colors. Nevertheless, I still believe the find is properly named. The dimensions of spores correspond to data from literature, but this usually doesn't mean much with boletes. More or less they all have very similar spores. - Two young pilei found. Hut diameter about 4 cm; stipe 6-6.8 cm long, in upper part 28 mm diameter, in lower part 40 mm diameter; slight rooting; taste mild, after some time slightly unpleasant; smell almost none; SP faint, almost invisible; all parts of the fruitbodies bruise to different colors, but not strongly; the colors disappeared after 24 hours of storage in refrigerator. - Spores smooth. Dimensions: (10) 11 - 13 (14.2) × (4.9) 5.2 - 6.4 (6.6) µm; Q = (1.8) 1.9 - 2.3 (2.4); N = 33; Me = 12 × 5.7 µm; Qe = 2.1.
