Original diagnosis: A. lugens mihi. Sporidiis ferrugineis, velo nullo, pileo carnoso-convexo, explanato testaceo-pallido, glabro, lamellis subliberis pallidis dein brunnescentibus, margine fusco-punctato, stipite solido striato albo basi incrassate sursum albo-pruinoso. Socialis. Pileus 2-3 unc. latus, laevis, sub lente areolato-striatus, e brunneo-expallens, sublutescens. Caro mollis alba. Lamellae simplices, inaequalis, leviter adnexae s. liberae, apice acutae 2 lin circiter latae, margine (a sporidis) ferrugineo maculato s. crenulato. Stipes 3-4 lin crassus, 2-3 uncias longus; striatus l. fibrillosus, fibrillis stipitis homogeneis, concretis, sursum albo-farinaceus s. flocculosus, basi subbulbosus. Odor subalcalinus. Velum non vidi, licet permulta individua vix e terra emersa, capitulum aciculatae referentia, per totum constantiae suae tempus, exploraverim. In sylvaticis montosis Hercyniae inf. Septbr.

English translation: My Agaricus lugens. With rusty red spores, no veil, with a fleshy, convex-expanded, pale brick red, glabrous pileus, with nearly free pale, later brownish lamellae, with a darkly punctate margin, with a solid, striate, white stipe, at base thickened, upwards with a white bloom. In groups. Pileus 5–7.5 cm wide, smooth, under the magnifying glass areolately lined, from brown fading, more or less yellowish. Flesh soft, white. Lamellae simple, unequal, slightly joined or free, with an acute, about 4 mm wide tip, with the margin (because of the spores) brown spotted or wrinkled. The stipe 6.5–9 mm thick, 5–7.5 cm long; with lines or fibres, with the fibres of the stipe homogeneous, condensed, upwards white mealy or fluffy, at base more or less bulbous. Odour more or less alkaline. I have not seen a veil, possibly (because) the very numerous specimens had hardly emerged from the soil, the little head resembling a needle. I will study its consistency [development] over time. In mountain forests of the Harz, September.

Commentary: This is described as without a veil, with rusty red spores and an alkaline odour. We suspect it is not a Hebeloma.
