Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1896 edition. Excerpt: ...and is not in very good condition. RHADINOMYCES Thaxter. Plate IX, figs. 7-15. Proc. Am. Acad. Arts and Sci. VoL XXVIII, p. 179. Receptacle consisting of two superposed cells, from the upper of which arise one to several stalked perithecia and a main appendage; the appendage consisting of three superposed cells, the upper bearing terminally a series of simple sterile brandies, the two lower producing from their distal ends short antheridial branches or long sterile branches or both. Antheridial cells flask-shaped, superposed in short series. Perithecia borne on a single stalk cell followed by four basal cells; its wall-cells four in each series. Spores once-septate. Trichogyne filamentous, simple or branched. Ascogenic cells, four. In some instances the sub-basal cell of the receptacle may produce one or more antheridial branchlets directly, in addition to those on the main appendage. The antheridial cells are sometimes single, more often superposed in threes, the upper one being free and terminal. A few specimens have been observed in which the antheridial brauchlets, instead of being borne directly from the primary appendage, as in fig. 12, arise from some of its ordinarily sterile branches. The ascogenic cells are readily made out in the paler species, and at maturity four may be usually distinguished; but this number does not seem to be constant even in the same species. In a few instances a peculiar spine, present also in other genera, has been observed near the base of the primary sterile branch (fig. 22) in R. cristatua; but its significance is undetermined. As has been previously mentioned, it may eventually prove necessary to unite this genus with Corethromyces. Rhadinomyces PALLIDUS. Plate IX, figs. 7-9. Proc. Am. Acad. Arts and Sci....show more
