CHAPTER 111.—SPORES OF FUNGI. 65 In basidia exhibiting successive abjunction of many propagative cells the process of abjunction is repeated several times on the same basidium. There are three very distinct sub-forms of successive abjunction, each of which has some special pecu- liarities connected with it. These sub-forms may be distinguished as the sympodial and the serial or concatenate (Reihen-weise, Kettenweise), the latter being again divided into the simple and the branched. In the successive sympodial form (Figs. 31, 32) a single acrogenous spore is first of all abjointed from the extremity of the basidium or sterigma, which is always finely pointed. Then a new protuberance sprouts forth close to the point of insertion of this first spore, pushes it on one side and occupies the extremity of the sporophore, and is there abjointed as a new spore. A like proceeding may be repeated many times; the last spore formed is always at the apex, and its older sisters are ranged on the same plane or one after another below the apex. In very extreme cases the.
