Boletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is an edible species of fungus in the mushroom family Boletaceae. The fruit body has several characteristics with which it may be identified: a dark reddish-brown cap; yellow to greenish-yellow pores on the undersurface of the cap; and a reddish-brown stem with long narrow reticulations. Boletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, B. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock, suggesting a saprobic lifestyle. Despite occasional appearances to the contrary, Boletus mirabilis is mycorrhizal, and forms close mutualistic associations with hemlock roots. There has been some disagreement in the literature as to whether the mushroom should be placed in the closely-related genera Boletus or Boletellus.
