Umbilicaria. - By "mnltilocular spores" is meant man; celled spores baring septa formed in two planes of thespore. 1. Biatorella. A very insignificant group; only one species has come to my notice. The thallus is very rudimentary or entirely wanting; repeated search is necessary to detect the algae (Protococcus). The apothecia are small, dark and considerably scattered, which adds to the difficulty of finding specimens. The spores are simple, small and colorless, sixteen usually occurring in each spore-sac. The Biatorellas seem to prefer sterile soil. 1. Biatorella geophana. Thallus deficient or wanting. Apothecia small. Disk convex, dark-brown. Spores simple, nearly spherical, colorless, 8/ X 2. Biatorina. This genus is likewise deficient in representatives. The thallus is rudimentary but readily recognizable; it is usually greenish in color and uniformly crustose, never becoming warty or areolate. The algae are bright-green, occurring in chains of rather small cells (Chroolepus umbrina). The apothecia are quite small. Disk flattened or slightly concave, brown or even pale-brown. Some authors combine this group with Biatora; but the elliptical, colorless, two-celled spores exclude it. They occur upon soil, tree-trunks and moss. 1. Biatorina lutea. Thallus thin, evenly spreading, somewhat granular, light-gray to greenish. Apothecia rather small, discoid. Disk of a yellowish waxy color. Spores colorless, elliptical, two-celled, 15//, X...
