Taxonomic status: We have not been able to unambiguously determine the current genus of this name.
Original diagnosis: 5 cm latum, carnosum, laeve, exstrium, aliquid depressum, colore avellaneo-alutacco, tenuissime velutino-fibrillosum; stipite brevi, 3 cm alto, 5 mm lato, albo, inferius albo-lanoso, radicante, ceterum albosquamuloso, squarruloso, inferius curvo, pedem versus dilatato: lamellis planis, densis, polymacriis, adnexis, etiam dente aut eroso- adnexis, pallidissime roseis, demum pallidis. Sporis 6-7x4-5 my, scabris, ovalibus, argillaceo-rubris, sub microscopio flavidulis. Odore nullo, sapore farinae dcbili. Basidiis valde clavatis, 24x10 my; cystidiis raris, cylindricis, angustis. A. H. austro-amecricano sporis prorsus diversus.
English translation: 5 cm broad, fleshy, smooth, non-striate, somewhat depressed, pale hazel brown, very finely velvety-fibrillose; stipe short, 3 cm high, 5 mm thick, white, white-woolly at base, rooting, for the rest white-squamulose, squarrulose, curved in the lower portion, broadened towards the base; lamellae segmentiform, crowded, of different length, adnexed, also emarginate or emarginate with a tooth, very pale pink, then pale. Spores 6-7 x 4-5 μm, roughened, ovoid, argillaceous-red, yellowish under the microscope. Smell none, taste faintly mealy. Basidia clearly clavate, 24 x 10 μm; cystidia rare, cylindrical, narrow. For the spores completely different from H. austroamericanum.
Commentary: In the diagnosis, the term "polymacriis" is a Greek compound, rarely used and taken to mean “of many dimensions”; referring to lamellae it probably should be interpreted as “of various length”. Thus far we have been unable to study type material of this taxon. Based on the diagnosis, it is not possible to determine whether this is a Hebeloma.
