. Comparative morphology of Fungi. Fungi. arch. asf——; 7. arch Fig. 229.—Humaria granulata. Development of the fructification. 1. Ascogonium, arch. 2. The same surrounded by sheath hyphae. 3. Autogamous nuclear pairing in the upper cell of ascogonium, asf. (1, 3 X 415; 2 X 285; after Blackman and Fraser, 1906.) Pezizaceae, they retain their position between the paraphyses. The Ascobolaceae, however, in the outward form of the fructification, have remained very monotonous and have developed very little beyond the disc form, while the Pezizaceae have attained a higher anatomical differ- entiation and form latex vessels which secrete a colorless or white solu- tion, which in Plicaria succosa turns yellow in the air, in P. saniosa blue. They also undergo distinct morphological development to stipitate, epigaeous cups, or to sphaerical, hypogaeous masses. The simpler genera, as Lachnea and Humaria, may be placed close to the Ascobolaceae; they form flat, patelliform fructifications whose periphery is crenate or torn. In the epigaeous series, however, as Pustularia, Discina and Acetabula, a stipe becomes more and more.
