Suillus granulatus

Ciri dan struktur

PILEUS: convex to plano-convex. 5-13-(16) cm diam., mucilaginous, glabrous, buff yellow, tan, reddish tan or orange cinnamon, occasionally dull reddish brown; cuticle an ixotrichodermium, readily separable; margin entire, often incurved and extending beyond pores when young. HYMENOPHORE: tubes 7-13 mm long, adnate to subdecurrent, pallid creamy white when young, becoming yellow to sordid yellow at maturity; pores concolorous with tubes, becoming spotted dark reddish brown at maturity, angular to radially elongated. 0.5-1 mm diam., beaded with droplets of cloudy, white liquid when young. STIPE: 4.5-8 cm long, more or less equal, 1-2.5 cm diam., solid, white to creamy white at first, becoming bright yellow apically, sordid brownish below; glandulae numerous, pinkish brown to reddish brown; flesh white at first, becoming yellow with age; annulus absent. SPORES: spore print yellowish brown (between Cinnamon and Pinkish-Cinnamon); spores pallid melleous, elliptic-subfusiform, 7.1-9.3-(10.6) X 2.8-3.1-(3.4) µm., smooth. HYMENIUM: basidia hyaline, clavate, 19-26 X 5.5-8 µm. 4-spored; cystidia scattered or crowded in groups at or near tube mouths, hyaline or encrusted with brown, resinous material, cylindrical to clavate, 33-45 X 6.5-10 µm. HYMENOPHORAL TRAMA: bilateral, of the Boletus subtype; clamp connections absent. CONTEXT OF PILEUS: white when young, becoming pallid yellow at maturity often with watery greenish yellow line immediately above tubes, unchanging on exposure to air. TASTE: mild. SMELL: not distinctive. CHEMICAL REACTIONS: KOH on pileus— greyish brown; on context of pileus—immediate red flush turning lilac; NH4OH on pileus—slowly darkening; on context—immediate red flush turning lilac.

Habitat dan peran ekologis

Suillus granulatus is an introduced species associated with Pinus in the temperate zone of the northern hemisphere and is widely distributed in both Europe and North America. The relatively large degree of variability encountered in Suillus granulatus over its natural geographical range has resulted in the recognition of a large number of infraspecific taxa. Of the more recent attempts to divide the species the most comprehensive treatments are those of Singer (1945a) and Blum (1965). Singer distinguished four subspecies on the basis of minor differences in spore size, small differences in colour of the fruitbodies, geographical distribution, and mycorrhizal associations in nature. The results of applying this classification to New Zealand specimens are inconclusive, for many collections possess spore and colour characters intermediate between two subspecies. However, it should be noted that Singer's classification arose from observations on specimens growing in their indigenous habitats. It is possible that under New Zealand conditions, where both fungus and mycorrhizal partner have been introduced, a degree of morphological modification of Suillus granulatus has occurred, with the result that subspecific differences are no longer distinct.
