Fungi. 320 COMPARATIVE MORPHOLOGY OF FUNGI which the formation of bacilliform cells on the mycelium is no longer indefinite but limited to the tips of the conidiophores; these arise only when the mycelium has attained a large expanse and by their general rich branching give rise to coremial formation (Fig. 210, 8). In nature these coremial formations have proceeded further to large, irregular, folded conidial layers of the color and consistency of apothecia, whose surface is occupied with conidiophores such as the mycelium produces.

These knobby stromata, in some species brightly colored, generally break out in groups (Fig. 211, 6); they gelify at maturity and are used by the natives for food. Numerous apothecia arise over the entire stroma under the cover layer (Fig. 211, c), and are only liberated at maturity by gelification of this tissue. In C. Darwini, the pycnia are found on the stipe in young fructifications, in C. Harioti sparsely scattered on the lower side, and in C. Hookeri on the apical portion (E. Fischer, 1888). All these stromatic Pezizales, despite their varied forms and unknown ontogeny form a special side line of the order. In the next groups, with- out stroma or epithecium, we deal with portions of the order which have been very much investigated cytologically. We will discuss two para-.
