Habitat: Mixed forest, Picea abies and Fagus sylvatica dominant, almost flat terrain, on overgrown alluvial deposits, calcareous ground; full shade, humid place, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 4-6 deg C, elevation 1.000 m (3.300 feet), alpine phytogeographical region.

Substratum: on lightly overgrown soil under a large Picea abies near its roots.

Place: Zadnja Trenta valley, left bank of (mostly) dry Soča river bed, north of Bavški Grintavec mountain, East Julian Alps, Posočje, Slovenia EC

Comments: This very beautiful mushroom was growing solitary; pileus diameter 9 cm; SP faint, brown, oac839. No typical red cracks on pileus surface observed. This species is considered very variable. Red stipe and cracked pileus surface with red context seen in the cracks seem to be two most distinctive traits of this bolete, however, they may also be totally absent.
