Weeping bolete

Appearance

The orange-brown, to brown-yellow cap is viscid when wet, and shiny when dry, and is usually 3 to 9 cm in diameter. The stem is pale yellow, of uniform thickness, with tiny brownish granules at the apex. It is without a ring. The tubes and pores are small, pale yellow, and exude pale milky droplets when young. The flesh is also pale yellow.

''Suillus granulatus'' is often confused with ''Suillus luteus'', which is another common and widely distributed species occurring in the same habitat. ''S. luteus'' has conspicuous a partial veil and ring, and lacks the milky droplets on the pores.

Distribution

Grows with ''Pinus'' on both calcareous and acid soils, and sometimes occurs in large numbers. ''Suillus granulatus'' is the most widespread pine-associating ''Suillus'' species in warm climates. It is common in Britain, Europe, and North America. It is associated with Japanese red pine in South Korea.
A native to the Northern Hemisphere, the fungus has been introduced into Australia under ''Pinus radiata''. It is also found in Africa, New Zealand, Hawaii, and southern Chile.
