Unequally cup-shaped, substipitate, versiform, cartilagineo-gelatinous, the two surfaces diverse in structure. Hymenium uni-lateral. Basidia linear, deeply bifurcate. Spores curved. Chains ofconidia produced on the tips of hyphse springing from the surfaceopposed to the hymenium. (Fig. 121.) Species 2037, 2038 Guepinia TREMELLINACEyE 457 2037. G. Peziza Tul. (from the Peziza shape) a b. Cup-shaped, cup oblique, sessile or stipitate, branches, wood. X * Fig. i2i.—a, b, Guepinia Peziza Tul., entire arid in section. X , basidium and spores. X 500. 2038. G. obliqua Mass, (from the oblique habit) a. Minutely hairy on reverse side of Hym. Hym. slightly concave,oblique, passing into a very short stem-like base, glabrous,deep bright orange when moist, tinged with pink when ^ in. high. Gregarious. CVI. DITIOLA Fr.(From the down-like universal veil; Gr. dittos, double, ionlos, down.) Veil universal, down-like. Stroma firm, more or less discoid, gelatinous. Basidia furcate. Spores at firstcontinuous then septate. (Fig. 122.) Massee has removed 2040 and made it the sole type of a newgenus, Dacryopsis. It is undesirable to break up such a small andnatural genus as Ditiola. Dacryopsis is said to be distinguished fromDitiola by having the hymenial surface at first covered with
