N1 - Funding Information:
We express our sincere thanks to Prof. Dr. N. Sagara for his valuable suggestions to the fieldwork in Japan. We are very much obliged to A. Bogaerts and P. Ballings of the Botanic Garden Meise (BR) for help with handling various loans from a variety of herbaria. We also thank these herbaria for their help: BP, BR, BRI, C, DPL, CBM, GENT, GLM, HO, IB, LOD, NRBC, PDD, PERTH, TNS, TUR-A and UTC. We are indebted to K. Asamoto, S. Hanawa, M. Hashiya, M. Ikeda, S. Inaba, E. Kurokawa and Y. Miyama for supplying us with interesting and exciting Hebeloma collections. This work was partly supported by JSPS KAKENHI Grant Number JP15K16279. Our thanks to K. Bensch and S. Pennycook for help with the correct form of the Latin epithet. We thank the reviewers and the editor for their helpful comments and suggestions.

N2 - Hebeloma radicosum, known for its long 'root' and membranous ring, has regularly been recorded in Japan and been the subject of many studies revolving around ectomycorrhizal fungi exposed to high levels of nitrogen compounds and tripartite associations between fungi, host trees and mammals, including moles, wood mice and shrews. However, the species recorded in Japan is in fact not H. radicosum but a closely related species, also in Hebeloma section Myxocybe, described here as Hebeloma sagarae. This mushroom is macroscopically very similar to Hebeloma radicosum, also with a long 'root' and membranous ring, but distinct molecularly and in its distribution. We also examine other 'rooting' Hebeloma species from Japan: H. luchuense and H. radicosoides; both are shown to be members of H. sect. Scabrispora. A fourth 'rooting' Hebeloma from Japan is shown to be the same as or a close relative of Hebeloma danicum originally described from Europe.
