Remarks (internal):The plant was first found by Ellis in Potsdam, N. Y., in 1855 and was sent for determination to Ravenel, whose reply was "new and very curious." No attempt, apparently, was made to describe or publish the species and it was soon buried in the mass of the Ellis collections. In the spring of 1904 the writer noticed the specimen, small and somewhat the worse for age, in the collection at New York and took notes on it. That very summer it was his fortune to find a considerable quantity of the same thing on a stump in Schaghticoke, N. Y., and it was from this material that the above description has been prepared.
The Webber and Holway specimens differ from the type plants in the pileus being plane with the surface nearly even. Apparently the ends of the branches do not project and form a roughened surface as in the type forms. It is doubtful, however, if they represent a fixed variation. These plants were referred by Ellis first to Hydnum cirrhatum Pers. and afterwards to Hydnum strigosum Swartz, but the character of the subiculum shows them to be distinct from either.

Description:Leaia piperata sp. nov.
Plant sessile, subdimidiate to flabelliform, caespitose, subimbricate, laterally confluent to 8 or to cm. wide; the pilei ascending toward the margin, 0.5-4 cm. wide, 1-3 cm. long, less than o.5 cm. thick excluding the teeth; the body of the plant composed of repeatedly branching but not anastomosing processes, tough, fibrous, flexible, umber, clothed above with a dense tomentum of brownish strigose hairs, the lower branches horizontal, with the teeth pendent from their lower sides, ending at the margin in vertically-compressed naked free ends which are paler and subtranslucent, the upper branches ascending and terminating on the surface of the pileus in terete free ends wholly surrounded with strigose branched hairs but with the tip naked, paler, subtranslucent, the projecting ends standing up like miniature spruce trees, the naked ends becoming blackish in old weathered specimens and in drying; margin fimbriate from the projecting ends of the branches; teeth slender, terete, acute, shortening toward the margin, 3 mm. long and less, 0.14-0.18 mm. wide, 2 or 3 to one millimeter, dark umber to pale brown toward the margin, in composition and color like the branched processes; spores ovoid or elliptical, hyaline, with one or more irregular guttulae, minutely papillose, 3.5-4 µm by 4.5-5 µm; sterigmata 3-3.5 µm long; basidia four spored, clavate; taste intensely acrid; odor not marked.
Han.: On very rotten stump in damp woods. June-Aug.
Range: New York, Ellis, Banker; Nebraska, Webber; Iowa, Holway.
The type material is in the author's collection preserved both dry and in formalin, the latter method seeming to preserve all the characters of the plant perfectly. Material obtained a year later from the same stump is in the New York State Herbarium at Albany. This species is the type of the genus.
