Boletales

views updated

Boletales (subclass Holobasidiomycetidae) An order of fungi which typically form mushroom-shaped, fleshy fruit bodies in which the hymenium lines the inner surface of tubes (pores) on the underside of the cap (as in Boletus) or forms a layer on the gills (as in Paxillus). Genera include both edible and poisonous species. They are found on the ground under trees, with which they commonly form mycorrhizal associations.
