From today's featured article

Suillus bovinus, the Jersey cow mushroom, is a pored mushroom in the family Suillaceae. A common fungus native to Europe and Asia, it has been introduced to North America and Australia. It was initially described as Boletus bovinus by Carl Linnaeus in 1753, and given its current binomial name by Henri François Anne de Roussel in 1806. It is an edible mushroom, though not highly regarded. The fungus grows in coniferous forests in its native range, and pine plantations elsewhere. It is sometimes parasitised by the related mushroom Gomphidius roseus. S. bovinus produces spore-bearing mushrooms, often in large numbers, each with a convex grey-yellow or ochre cap reaching up to 10 cm (4 in) in diameter, flattening with age. As in other boletes, the cap has spore tubes extending downward from the underside, rather than gills. The pore surface is yellow. The stalk, more slender than those of other Suillus boletes, lacks a ring. (Full article...)

Today's featured picture

Battus polydamas, also known as the gold rim swallowtail, the Polydamas swallowtail or the tailless swallowtail, is a species of butterfly in the family Papilionidae, found in the neotropic ecozone of South America, the southeastern U.S. and Mexico. The species was first described by Carl Linnaeus in his 10th edition of Systema Naturae, published in 1758. Its wingspan is 90 to 120 mm (3.5 to 4.7 in) without the tail. The oversides of the wings are black, with a broad submarginal band formed by large yellow spots. The undersides of the forewings have the same pattern, while the hindwings have a submarginal row of red lunules. The larvae feed on Aristolochia plant species.

This picture shows the underside of a B. p. jamaicensis butterfly, a subspecies endemic to Jamaica.
