Taxonomic status: Heterotypic synonym of H. incarnatulum
Basionym: Hebeloma crustuliniforme f. sphagnophilum Kauffman (1918)
Types: UNITED STATES: Michigan: Washtenaw, Mud Lake, West of Whitmore Lake (approx. 42.4139°N, 83.7939°W, alt. approx. 270 m a.s.l.), 20 Oct. 1906, C.H. Kauffman (Holotype. herbarium acc. no. MICH 10723, HJB1000335).
Diagnosis: Form sphagnophilum: These plants grew on dense sphagnum. PILEUS 4-7 cm. broad. STEM 7-9 cm. by 5-8 mm. There are no cystidia on the sides of the gills; the sterile cells on the edge are slender, slightly thickened below, cylindrical above. The edge of the gills distills drops. The odor, when the plants are fresh, is similar to alcohol ethers. Otherwise as the type. See Plate XCVII of this Report. The most striking characteristic of this species and its varieties is their habit of distilling drops from the gills when fresh or moist. In this respect it imitates H. fastibile, but lacks the cortina and has more crowded gills. It is considered poisonous, and is said to be called “poison-pie" in England, no doubt because the color of the cap simulates a baked piecrust. In dry weather it is easily confused with other species, and the occurrence of the forms mentioned above shows that it needs further study. It does not seem to be as common here as in Europe.
