Dermoloma magicum spec. nov., a grassland gungus mimicking Porpoloma metapodium

Dermoloma magicum is proposed as a new species, characterised by reddening, then blackening basidiocarps, a unique feature within the genus Dermoloma. The species has been collected in grasslands in the Netherlands and Scotland. The collections were initially identified as Porpoloma metapodium. The differences with that fungus and with related Dermoloma species are discussed.
