Original diagnosis: Einzeln auf grasigen Blössen in Rw. Hut. unregelmässig ausgebreitet, selbst. ausgeschweift, bis zum Rande fleischig, 2” und etwas darüber breit., glatt, etwas glänzend, bei feuchtem Wetter ein wenig klebrig, bei trockenem radienförmig von der Mitte zersprungen, gelb-lederbraun. Die Lamellen stossen kaum an den Strunk an, sie sind beiderseits abgerundet, linear, bei 3’’’ breit, weit, gelb-zimmetbraun. Strunk in den Hut übergebend, verkehrt-conisch, oben bei 9’’’ dick, 1- 5/4’’ lang, weiss, voll und hat - gleich dem Hute - ein festes weisses Fleisch. Sporen dunkel-rostbraun, lang-verkehrt-eiförmig, 0,01 mm. lang. Geruchlos und ohne besonderen Geschmack.

English translation: Solitary on grassy open spots in Rw. Pileus irregularly expanded, even reflexed, fleshy up to margin, 5 cm broad and somewhat more, glabrous, somewhat shiny, slightly viscid in moist weather, when dry radially splitting, yellow to leather brown. Lamellae hardly attached, rounded to both ends, linear, about 7 mm broad, distant, yellow to cinnamon. Stipe continuous with pileus, obconical, at apex to 20 mm thick, 25–35 mm long, white, full, it has, like the pileus, solid white flesh. Spores dark rusty brown, elongate obovate, 10 μm long. Without odour and with indistinct taste.

Commentary: The pileus is described as cracking radially, which does occur in a few Hebeloma species, e.g. Hebeloma mesophaeum. However, it is also described as having no significant smell. We cannot unambiguously interpret this species.
