Abstract

(i)THE DULLER'S investigations, undertaken with the object of throwing light upon the production, liberation, and dispersion of spores in the group of fungi known as the Hymenomycetes, breaks new ground, and, as usual in such instances, will undoubtedly form the starting point of future research on the part of many students. A brief sketch of the components of a typical hymenium or spore-bearing surface are first dealt with. It is pointed out that swollen gill-margins serve to separate the gills, otherwise the spores could not be shed. This may be true in those instances where thickened gill edges exist, but in at least seventy-five per cent, of known agarics the edge of the gills is not in the least thickened.
