Rhizopogon roseolus, shōro (Japanese: 松露/ショウロ), is an ectomycorrhizal fungus, considered a delicacy in east Asia and Japan[2] and used as a soil inoculant in agriculture and horticulture.

The sterigmata are as long as the spores, which are uniquely colored, some ocher-tawny, smooth, and ellipsoidal in shape; they measure 7-16 by 3-5 μm.

Rhizopogon roseolus is considered a cosmopolite species,[4] distributed in Europe, North America and northeastern Asia.

In Europe it grows under Pinus nigra on calcareous soil, and it forms fruiting bodies from August to November.

[5] Techniques for the commercial cultivation of this fungus in pine plantations have been developed and applied with successful results in Japan and New Zealand.
