Laccocephalum basilapidoides

Laccocephalum basilapidoides is a solitary fungus with annual hymenophore. The woody and pitted pileus (13/4-15/4 inches in diameter) is irregularly concave in the middle while convex in the remainder. The pileus is brownish fawn with coffee-colored margin, the inner substance of which, however, is thick, whitish, and unchangeable. Pits are relatively small and conical in the middle whereas larger and elliptical in the surrounding rows. The hymenophore is greyish-fawn to reddish-brown, solid, and continuous with stem, which consists of adnate tubes and large, crowded, and oval pores. The spores are spherical (44-50 μm in diameter), orange-yellow, and echinulate with spines 3 μm long. The fawn stem is compressed oval, 1/2*3/4 inches in diameter and 1 inch in length, which rises abruptly from a whitish mycelium 3 inches in height and 13/4*4 inches in diameter. The mycelium agglutinated grains of the sandy soil to form a stone-like basal portion resembles a concretion of ferruginous sandstone in appearance and almost in density (the whole fungus in the figure weighed as heavy as 13.25 ounces).
