It is true also of Scleroderma vcrrucosum, according to Sorokin's recent observations, except that the hymenial coil in each chamber of the gleba is formed, if that observer is correct, by the branching of a single hypha which grows from the wall into the chamber at a very early period of the development. The ripening of the gleba begins in Geastcr hygrometricus (Fig. 146) at the apex and advances from thence towards the base. According to Bonorden's and Tulasne's statements it begins in Lycoperdon and Scleroderma in the middle line and proceeds centrifugally; according to Sorokin the points where the ripening commences in Scleroderma vcrrucosum vary in different individuals, but are always situated inside the gleba. The fully formed capillitin7ii consists in most of the forms first to be considered of a countless number of single tubes or portions of hyphae, which are only woven, not grown, together and can therefore be easily isolated without tearing. Form, size, and structure in these capillitium-threads are different in different genera and species, and serve admirably to distinguish the latter. The threads are generally unsegmented and unicellular ;. }" 11. 145.
