location
Lower Trenta valley, between villages Soča and Trenta, right bank of river Soča, close to the place where the trail to abandoned settlement Na Skalah passes the ravine Sraunk, East Julian Alps (Posočje, Slovenia)notes Slo.: jamičasti goban - syn: Boletus depilatus Redeuilh, Leccinum depilatum (Redeuilh) Šutara, Xerocomus depilatus (Redeuilh) Manfr. Binder & Besl - Habitat: light, young mixed wood and bushes, Ostrya carpinifolia dominant, some small, young Picea abies, a few very small (< 1 m tall) Fraxinus ornus, no Quercus and Carpinus in the vicinity; sparsely grass overgrown terrain in a mountain ravine; moderately inclined mountain slope, southeast aspect; base rich, colluvial, skeletal, calcareous ground, very shallow, soil layer on scree, sand and stones; half shade, relatively warm place; average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, elevation 745 m (2.440 feet), alpine phytogeographical region. Substratum: soil among stones under Ostrya carpinifolia canopies. Comments: These yellowish appearing and not bruising boletes seem to be rather rare Hemileccinum depilatum. Typical traits of this find like curved, tapering or spindle-shaped stipe, fibrillose stipe surface, decidedly clear yellow pores when young, practically unchanging color of tubes, pores and flesh after exposure to the air, sometimes slowly reddening of the flesh above the tubes (see picture no.25), indistinctive taste, generally indistinctive smell except at base of stipe (unpleasant on chemicals)¸ pileipellis with erect hyphae composed of ± inflated cells (as the most important distinguishing trait according to Ref.: 2), almost certain mycorrhizal relation with Ostrya carpinifolia (Ref.: 3) and obligatory calcareous ground, all fit well to the species description in literature. Description: Six pilei growing scattered, two growing together; pilei diameter from 5.5 to 17.5 cm, max tubes length 15-16 mm, context thick up to 22 mm; stipe length 7.5 to14 cm with 3 to 4.4 cm max diameter, usually tapering into a rooting base; smell almost absent or very mild, not unpleasant except in the base of the stems; taste mild, pleasant, a little bit mucous; flesh when cut not bruising; pilei surface and pore layer slightly sticking when touched (in dry weather). SP yellowish-ocher-brown, oac805. Spores smooth. Dimensions: 12 [13.6 ; 14.3] 15.8 x 4.1 [4.8 ; 5.2] 5.9 microns; Q = 2.4 [2.7 ; 2.9] 3.2; N = 32; C = 95%; Me = 13,9 x 5 microns; Qe = 2.8. Dimensions of subglobose or shortly cylindrical terminal cells of palisadoderm pileipellis hypha: 24 [34.3 ; 40.7] 51.1 x 11 [15.3 ; 17.9] 22.2 microns, Q = 1.3 [2.1 ; 2.6] 3.4; N = 18; C = 95%; Me = 37.,5 x 16.6 microns; Qe = 2.3.
