In the forest-clad portions of the Pacific Coast Range, from the Columbia River northwards inot British Columbia, there are frequently seen on the trunks of pine trees which have been injured and blackened by fire, small white fungi almost globular, or slightly flattened and kidney shaped, varying much in size, but frequently attaining the dimensions of a pigeon's egg. This fungus, kindly determined for Mr. E. A. Schwarz and myself by Prof. Galloway, is Cryptoporus (Ployporus) volvatus, Peck., var. obvolutus, Peck.
