description
Pileus up to 8 cm diam., convex, tomentose, matt, dry, hazel-brown to buff-brown, becoming dark blue black when bruised. Cap margin slightly incurved. Stipe up to 9 cm long, up to 3.5 cm wide, cylindrical, tapered, sometimes rooting, lemon-yellow, without a network; stipe surface becoming intensely blue black after handling; basal mycelium white. Context initially lemon-yellow or greenish yellow, becoming intensely dark blue when exposed to air and then gradually fading to greenish. Tubes up to 12 mm long, adnate and slightly decurrent, initially lemon-yellow, then yellow olivaceous, turning blue green or blue black when bruised. Pores medium sized, angular or irregular, lemon-yellow; becoming dark blue when injured. Smell slightly acidulous. Taste mild, slightly acidulous. Spores 11 – 13 × 5 – 5 · 5 μm (distribution of average values from 4 collections, 182 spores), ellipsoidal, sometimes weakly fusiform, smooth, thick-walled, guttulate, light yellow brown. Caulocutis fertile. Pileipellis a trichoderm of intertwined septate hyphae, consisting in cylindrical, filamentose cells (3 · 5 –) 5 – 6 (– 7 · 5) μm broad, mostly widely and finely incrusted on the surface, and also with yellow-brown intracellular pigment. Crystals on the surface of hymenium are visible under SEM microscope.
discussion
Notes: Based on Boletus pulverulentus Opat. sensu Biketova et al., New, noteworthy, and rare species of the genus Boletus in Israel. Plant Biosystems 150 (5): 883 (2016). A species with boletoid basidiomes, close to Cyanoboletus pulverulentus (Opat.) Gelardi, Vizzini & Simonini, the latter based on findings of north-east Europe (Opatowski, Wiegmann Archiv für Naturgeschichte 2 (1): 27. 1836), which is distinguished from C. mediterraneensis by the different genetic characteristics and the prevailing distribution, which also includes temperate and continental climates.
