Differs from D. blumei as follows: hairs of under-coat on the stipe shorter, thicker, but flaccid with walls collapsed when dry; hairs on lower surface of pinna-rachis and costae more numerous, appressed, flaccid, mostly ascending; spores bearing conspicuous more or less coalescent warts.
Mountain forests, 1500-2000 m. The Celebes specimen, much smaller than those from Borneo and the Philippines, was found at 2900 m, in dry open Vegetation (Eyma 959); it lacks a stipe. It agrees better with D. mollis than with New Guinea species (it is certainly not D. blumei), but without more complete material its status is doubtful.
