DUNCAN CHIQUOINE Department of Biology, Princeton University, N. J. As Buller (1909 ct scq.) has pointed out, some species of the genus Copriniis sow their spores once during a short interval of time and the fruiting body disap- pears shortly thereafter by auto-digestion. Characteristically the small buds will, all in one clay, go through a period of rapid expansion and elongation, shed their spores, and deliquesce. This rapidity is no doubt related to their small size, for larger species of hymenomycetes will go through many days of continued production and shedding of spores. The origin of the gills and their individual lamellae has been described in detail by Atkinson (1916). They are formed at an early stage by the orientation of hyphae and the final result ( which is illustrated in Figure 1) has a number of distinguishable component parts: the outside is covered with the hymenium which consists of a mixture of basidia and sterile paraphyses; below this there is a sub- hymenial layer of small hyphae ; and finally the central portion of the gill lamella, the tramal layer, which is composed of large hyphae. Borriss (1934) has shown that the development of Coprinus occurs in two distinct stages, one in which cell division and the initial cell orientation takes place, and it is during this stage that the gill primordia are formed. The second stage consists of rapid cell elongation and in the latter phase of this period the spores bud from the basidia. It may be inferred, from the recent results of Madelin (1956), that this period of rapid expansion involves the transfer of material from the vege- tative mycelia. Such a transfer is in keeping
