Thebasidiosporous Fungi are character- ised by the presence of a distinct membrane (hymenium), on the surface of which the spores are developed by a mode which, though it is still acrogenous, is considerably more complicated. The hymenium always consists of elongated pouch-like cells, ar- ranged side by side, with their long axes perpendicular to its surface, and in close contact with each other. Some of these cells are longer than their neighbours, and from their free rounded ends, there emanate processes (usually four in number) in the form of pedicles. Upon the extremities of these are borne oval cellules, which, though in their Fig. A basiuliim with its four basidospores, along with two other sterile basidia (Geaster mfescsns), 300 diam. earliest condition they do not exceed their pedicles in width, rapidly enlarge, and finally separate by a kind of constriction. In some basidiosporous Fungi, as in the Agarics, the hymenium is external, and its surface exposed to the atmosphere; while in others, as in the Gasteromycetes, it is internal, the spores being thrown, when detached from their pedi- cles, into one or more cavities enclosed in the substance of the receptacle. Of the last- mentioned division, we select a well-known genus (Geaster), for the purpose of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Todd, Robert Bentley, 1809-1860.
