A new species of the coelomycete genus Rhizosphaera found on needles of Pseudotsuga menziesii in Germany is described, illustrated and compared with related species of the same genus. The conidia of R. pseudotsugae are smaller, especially in diameter, than those of the most similar related species, R. oudemansii, and unlike other Rhizosphaera species the Hormonema state is produced in culture only at temperatures below 18 °C.

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.
