Hebeloma radicosoides sp. nov. is described, illustrated and characterised. It superficially resembles H. radicosum in having a long-rooting stipe with a well-formed, membranous annulus and in having preference for animal wastes as its resources. Its pileus is
yellower than that of H. radicosum, and it fruits after addition of urea to soil, whereas H. radicosum does not. It also fruits on various
animal wastes whereas H. radicosum specifically fruits on mole or mouse middens. Unlike H. radicosum, H. radicosoides has no distinct
odour. Hebeloma radicosoides also resembles Hebeloma luchuense and H. spoliatum in having a long-rooting stipe and in fruiting on
urea-treated soil, but differs from them by having a yellowish scaly pileus and distinct, membranous annulus.
