Amylosporus campbellii (Berk.) Ryvarden., Norw. J. Bot. 24: 217. 1977.
Description：
Basidiocarp annual, pileate, laterally stipitate or sessile to dimidiate, single to clustered, up to 20 cm wide and 7 cm thick at the base, soft when fresh, light and fragile when dry; upper surface first finely tomentose becoming glabrous with age, whitish to creamy when fresh, becoming light buff to light ochraceous-buff with darker spots to cinnamon-brown when dry. Pores angular to round, 2-4 per mm, concolorous with upper surface. Context fibrous, up to 3 cm thick. Odor of specimens becoming malodorous like rotten vegetables. Hyphal system dimitic; generative hyphae hyaline, thin-walled, with simple septa but occasional with single, double or multiple clamps, 4-12 µm wide, skeletal hyphae hyaline, aseptate, 3-7.5 µm wide, gloeoplerous hyphae persent, thin-walled and filled with refractive contents, 3-9 µm wide. Basidiospores oblong ellipsoid to broadly ellipsoid, hyaline, smooth to finely asperulate, 4.5-5.5 × 2.5-4 µm, amyloid.

Note：
The occurrence of double and multiple clamps, an unusual character in polypores, characterizes this species. The specimens are very malodorous like rotten vegetables if the basidiomata are not dried out immediately after collection.
