The truth cannot be determined without consulting the older authors and herbaria and endeavoring to understand what their limitations were both as to apparatus and collections. I propose in subsequent articles, by reproducing the original descriptions, illustrations and criticisms to show how much we still need the benevolent services of some Euro- pean bryologist, who will take the time and means to determine what the originals were of some of the older species of Fissidens. New York Botanical Garden. FUNGUS-SPORES IN A MOSS-CAPSULE Elizabeth M. Dunham While examining some mosses collected at Miami, Florida, by Mrs. F. E. Lowe of Worcester, Mass., we found one capsule of Funaria hygrometrica var. patula Br. & Sch. containing four-celled ciliated bodies in place of the usual moss- spores. These were identified by Dr. Roland Thaxter of Harvard College as the spores of a species of Pestalozzia, a genus of the imperfect fungi. This group of fungi may represent special stages in the life cycles of other fungi, since little is known of them at present except the spore- stage. Pestalozzia is readily distinguished by the peculiar conidia or spores which are borne on rather short stalks and are spindle-shaped, divided into four parts. The apical and basal cells are hyaline and the central ones dark. The apical cell is provided with one or more filiform appendages. Pestalozzia is one of the leaf-bli
