Slo.: noroglavka, svinjski goban - Habitat: southeast inclined mountain slope, mixed wood, dominant trees Ostrya carpinifolia, Picea abies and Fagus sylvatica; in a thicket of young Picea abies, in shade, relatively warm place; calcareous ground, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 750 m (2.500 feet), alpine phytogeographical region. - Substratum: soil covered by leaf in needles litter. - Comments: Although Boletus luridus is probably the most frequent of all boletes in Posoje and I've seen and photographed them many times, I could not resist taking pictures of this beautiful group of a few young fruitbodies well hidden under young European spruce thickets. Boletus luridus is very colorful, meaning more many colored than of one or two saturated uniform colors. One can find all kinds of shade of red, blue and green (when bruised), yellow, ocher, brown, black and who knows which else color. Having very characteristic red net on its stipe, it is usually easy to determine it correctly. Rapidly and drastically changing color on all its parts when handled also helps. Some people claim it is eatable but I haven't (yet?) try it. All I know is that snails like it very much. - Ref.: (1) Personal communication with Mr. Anton Poler.

Slo.: grenki goban - syn. Boletus albidus - Habitat: mixed mountain wood, dominant trees Fagus sylvatica and Picea abies; moderately steep mountain slope, south aspect; calcareous ground; in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 3-5 deg C, elevation 1.260 m (4.150 feet), alpine phytogeographical region. Substratum: forest soil. Comments: Texture and color of the upper surface of the hut, rooting stipe, turning blue on bruising and, in particular, very strong bitter taste are typical traits of Boletus radicans. What surprises in this find is reddish coloration of damaged places (by snails) and quite distinctive reddish tones of the stipe. This is unusual with Boletus radicans and causes some doubts in our determination. However, no better alternatives have been found. Growing solitary; pileus diameter 8.5 cm; taste strongly bitter, smell faint, unpleasant; quickly bruising blue-green when handled; SP faint, color indistinguishable. Spores smooth. Dimensions: 12.4 [13.7 ; 14.2] 15.5 x 5 [5.5 ; 5.8] 6.3 microns Q = 2.2 [2.4 ; 2.5] 2.8; N = 34; C = 95%; Me = 14 x 5.6 microns; Qe = 2,5.

Slo.: gabrov bed - ; Synonymy: Boletus griseus (Qul.) Sacc. & D. Sacc., Gyroporus griseus Qul., Leccinum griseum (Qul.) Singer., Leccinum carpini (R. Schulz) M.M. Moser ex D.A. Reid ?, Leccinellum pseudoscabrum (Kallenb.) Mikk ? - Habitat: predominantly hard wood, broadleaf tree forest; moderately inclined mountain slope, southwest inclination; cretaceous clastic rock (flysh) bedrock, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 460 m (1.500 feet), alpine phytogeographical region.Substratum: soil.Comments: Members of genus Leccinum/Leccinellum are relatively easy to recognize by distinct stem squamules. However, their taxonomy is a problem and species determination is often difficult. No definite and generally accepted answers are known. In 1995 the genus Leccinum comprised about 36 species distinguished by their macro-characters. Ten years later, in 2005, only 14 were still recognized based on DNA analysis (Kibby 2011). It has been proven that some traditional traits, which seemed once very important (for example flesh color changes when cut) have little significance. A new genus Leccinellum was established based on characteristics of hypha in hut cuticle. Yet not all mycologists agree with this approach. Such situation reflects in the fact that in Index Fungorum (IF) current name of this observation is probably Leccinellum griseum, while MycoBank still keeps with the current name Leccinum griseum. There are several ambiguities about species names and I am not sure I handled them correctly. Be that as it may this species doesn't look too appealing for photography, particularly not when old (as on these photos). But it is quite common in Slovenia and edible, and of very good taste (when younger). In this observation it was growing solitary. Spores smooth. Dimensions: (15,1) 15,3 - 16,7 (17,4) (5,2) 5,3 - 5,9 (6,3) m; Q = (2,4) 2,7 - 3,1 (3,2); N = 10; Me = 15,9 5,6 m; Qe = 2,8.
