Suillus luteus

Ciri dan struktur

PILEUS: convex to plano-convex, 6-12 cm diam., mucilaginous, glabrous, sometimes faintly and innately radiately fibrillose, typically dull reddish brown or chocolate brown, occasionally golden brown, tawny, or with greyish or purplish overtones imparted by the thick mucilage layer; cuticle an ixotrichodermium, readily separable; margin often lacerate. HYMENOPHORE: tubes 5-10 mm long, adnate to sub-decurrent, whitish to pallid yellow when young, becoming deep ochre yellow at maturity; pores at first concolorous with tubes, becoming spotted dark reddish brown, irregularly angular, 0.5-(l) mm diam. STIPE: 4-9 cm long, more or less equal, 1-2.5 cm diam., solid, pallid yellow above annulus, brownish below; glandulae numerous apically, yellow to reddish brown, fewer and more scattered basally; flesh white to pallid yellow: annulus conspicuous, occasionally disintegrating with age, superior, broadly sheathing, upper surface sordid white, lower surface with purplish tints. SPORES: spore print yellowish brown, (Clay Color); spores pallid melleous, elliptic-subfusiform, 7.4-9-(10) X 2.5-3.2 µm, smooth. HYMENIUM: basidia hyaline, clavate, 14-26 X 4.5-7.5 µm, 4-spored; cystidia often crowded in groups, hyaline or encrusted with brown, resinous material, cylindrical to clavate, occasionally lageniform, 25-65 X 6-12 µm. HYMENOPHORAL TRAMA: bilateral, of the Boletus subtype; clamp connections absent. CONTEXT OF PILEUS: white to pallid yellow, unchanging on exposure to air. TASTE: mild. SMELL: not distinctive. CHEMICAL REACTIONS: KOH on pileus—dark grey; on context of pileus—immediate red flush turning lilac; NH4OH on pileus—dark grey; on context—immediate red flush turning deep lilac to purplish.

Habitat dan peran ekologis

Suillus luteus is an introduced species indigenous to the temperate zone of the northern hemisphere. Singer (1945b) considered that in its natural habitat, S. luteus was associated with 2-needle pines belonging to sect. Lariciones of the genus Pinus, but later (Singer, 1965) added Picea abies and possibly Larix decidua to the list of mycorrhizal partners. Smith and Thiers (1964) commented that Suillus luteus occurred with Pinus and Picea in North America and remarked that its distribution in native coniferous forests was yet to be ascertained. It seems likely that over its natural geographical range Suillus luteus shows a preference for certain species of 2-needle pines, but in New Zealand is capable of forming associations in the field with species of 2-, 3-, and 5-needle pines in the absence of its preferred partners. Experimental data support this conclusion, for in pure culture S. luteus has been shown to form mycorrhizas with a number of 2-, 3-, and 5-needle pines as well as Picea abies, Larix decidua, and L. occidentalis (Slipp and Snell, 1944). Birch (1937) has proved experimentally that Suillus luteus forms mycorrhizas with Pinus radiata in New Zealand. Suillus luteus is an excellent edible fungus.
