Original diagnosis: Ochraceo-carneus, nitoris expers, stipite basi subbulboso, toto floccoso-hirto, pileo glabro, subviscoso, laminis pallidis, brunneo-fulvellis. Fungi habitus valde unicolor, obsoletus et rudis. Pileus convexus, cucullatus vel conicus, forma varius, validus quidem, sed aequaliter a medio versus marginem acutum decrescens, stipiti tantum impositus, totus in superficie viscoso-roridus, in margine albentior. Stipes basi plus vel minus bulbosus, et varie elongatus, opacus, siccus, hirtus, floccis distantioribus vel confertis, revolutis, superne densioribus, et ibidem sub pileo cum stipite albis. Intus stipes a medio versus summum sensim magis excavatus, fasciculo fibrarum superne a pilei substantia in cavum stipitis dependente. Laminae ochraceo-fuscae et subfulvellae, in brunneum vergentes, oblongae, utroque termino acutae, marginibus convexae, latuisculae, soli pileo adnatae, triplici ordine alternantes. Majores circiter 60. Substantia in toto fungo subaequalis alba, solida, praecipue in bulbo et pileo, in stipite subfibrosa, et in ejus cortice colore fungi externo imbuta. Copiose crescebant fungi in pinetis ante sylvulam Forst, et in monte Jenzig, initio Octobris 1788.

English translation: Ochre-incarnate, non shining fungus, stipe subbulbous at base, entirely floccose-hairy, pileus glabrous, subviscid, lamellae pallid, brown-yellowish. The whole fungus is unusually unicoloured, dilapidated and rough. Pileus convex shaped like a hood [umbonate] or conical, very variably shaped, certainly thick, but gradually becoming thinner from centre to margin; simply set on the stipe [meaning not confluent], entirely viscid-moist, more whitish to the margin. Stipe with a more or less bulbous base and elongate, opaque, dry, hairy, with distant to crowded, recurved flocks, denser in upper part, whitish under the pileus. The inner part of the stipe becomes hollower from the middle upwards, and the context of the pileus hangs down in fibrous bundles in the cavity. Lamellae ochre-brown or brownish red, changing deep brown, oblong, attenuate towards both ends, with convex margin, somewhat broad, attached only to the pileus. They are divided in three lengths, the largest counting about 60. The context in the whole basidiome is similarly white, solid, especially in the pileus and bulb, in the stipe somewhat fibrillose, and in the cortex tinged with the external colour. Growing abundantly in the pine woodlands of Forst and in the Jenzig Mountains, early October 1788.

Commentary: This taxon is discussed in detail in Grilli et al. (2015). Agaricus subtestaceus is described from mountainous pine forests and, with the entirely foccose and bulbous stipe, it obviously lacks a veil. It appears to be a member of Hebeloma sect. Velutipes and is most likely the same as Hebeloma leucosarx. However, we cannot totally rule out that this may be H. velutipes or a member of the quercetorum-complex. Our conclusion must be that we cannot, unambiguously, determine the identity of this taxon
