It follows the same type in the Agaricini, Boleti, some Polyporei, and Hydnei. This type is a convex, or primarily convex, orbicular expansion of the apex of the stem, with a more or less distinct pellicle on its upper surface, an intermediate stratum, and its lower sur- face covered by the hymenium. In this type, then, it is a hymenophore, as it is in other forms of Hymenomycetes. This cap (Fig. 16) not only surmounts, but it is continuous with the stem, and for the most part conforms to it in texture. In some cases it passes down in plates on the under surface between.

The superior cuticle or pellicle is sometimes so distinct from the subjacent stratum that it may be stripped off, but in other species it is so intimately incorporated with the substratum that it is inseparable. From the margin of the cap this cuticle is sometimes extended inwards and united to the stem, covering the young hymenium, and forming a veil. Externally the cuticle may be quite dry or viscid, or even covered with a slimy gluten, as in Agaricus mucidus and Agaricus aeruginosas. In some cases the cuticle is compara-.
