Strobilomyces foveatus is a little-known species of fungus in the Boletaceae family. It was first reported by mycologist E.J.H. Corner in 1972, from specimens he collected in Malaysia in 1959, and has since been found in Australia. Fruit bodies are characterized by the small dark brown to black conical scales covering the cap, and the net-like pattern of ridges on the upper stem. The roughly spherical spores measure about eight micrometres, and are densely covered with slender conical spines. The edibility of this species is unknown.
Strobilomyces foveatus was first described scientifically by mycologist E.J.H. Corner in 1972, from specimens collected in Sarawak, Malaysia in 1959. It was one of several new Strobilomyces species he described in his monograph of Malaysian Boletaceae—the others were S. annulatus, S. mirandus, and S. mollis.
The fungus is classified in the section Strobilomyces of the genus Strobilomyces. Species in this section are characterized by having spores that may be either smooth or with short spines or warts, ridges or reticulations. The ornamentation is reduced or absent in the suprahilar region (a depressed area near the ). The specific epithet foveatus is derived from the Latin adjective foveola, referring to a surface with pits or depressions.
The caps of the fruit bodies are between 7 to 10 cm (2.8 to 3.9 in) wide, with a convex shape. The cap surface is covered with dark brown to black erect scales between 1.5–3 by 1.5–2.5 mm. The stem is up to 12 cm (4.7 in) long; it is 1.2 cm (0.5 in) thick at the top, and 1.5 cm (0.6 in) thick at the bottom. The surface of the upper stem is strongly reticulate (covered with a network-like pattern) with individual meshes about 2–4 mm wide and 1–2 mm deep. The pores on the underside of the cap are between 0.5–1 mm wide, dirty white then gray, and they bruise a brownish-black color. The tubes which make up the pores are up to 1.2 cm (0.47 in) long. The flesh is thick and initially white, but will stain a brownish-black after exposure to the air.
