Description |
||
Black Velvet Bolete is a dark, medium-sized mushroom. It occurs in eastern Asia and North America. In the United States it occurs from Massachusetts to Florida, west to Minnesota and eastern Texas, and in southern Ontario Canada. It is rare in Minnesota, where it is at the western extent of its range. It is found in summer and fall, alone, scattered, or in groups, in deciduous and mixed woodlands. It grows on the ground, usually under hardwood trees, especially oak. It has a mutually beneficial relationship (mycorrhizal) with the tiny rootlets of trees, absorbing sugars and amino acids while helping the tree absorb water. The cap is blackish-brown to dark grayish-brown or black. When it first appears it is convex, the upper surface is dry and is densely covered with short velvety hairs, and it is covered with a whitish to gray powder. As it matures it flattens out, becoming broadly convex. The mature cap is hairless and 1½″ to 3¾″ (4.0 to 9.5 mm) in diameter. When handled it bruises black. Older caps are finely cracked. The stalk is dry, hairless, 2″ to 2¾″ (5 to 7 cm) long, and ⅝″ to ¾″ (15 to 20 mm) thick. It is more or less equal in size but is sometimes enlarged at the base. It is the same color as the cap or a little lighter for most of its length, whitish and pinkish near the top. The surface is usually not covered with a network of fine ridges (reticulate) but is sometimes reticulate near the top. It bruises dark brown to black when handled. The pore surface is bright white when young, becoming pinkish as it ages. When bruised it usually stains first red then brown and eventually black, but sometimes goes directly to black. There are 2 pores per millimeter. The pore tubes are up to ⅜″ (10 mm) deep. The flesh is thick and white. When sliced it stains pinkish at first then slowly turns gray when exposed to air. It is edible when young, but like other boletes, mature specimens are often riddled with maggots. The spore print is pink. |
