The formation of mucilage advances at the same time from the inner peridium inwards, and leaves round each of the muci- laginous areolae a border of air-containing tissue (Fig. 229), which afterwards developes, by the dense interweaving of its branched hyphae, into a firm envelope consisting of two layers, in which the mucilaginous areola lies. Each of these areolae becomes a hyme- nial chamber. While the centre of the Fungus is becoming changed into mucilage,.
