. Text-book of botany, morphological and physiological. Botany. CARPOSPOREM. 339 of their spores (eight spores are often produced on a basidium); but their fructifications are always angiocarpous. The hymenia are formed in the interior of the fructification, which is at first usually spherical, or at any rate does not present externally any distinc- tion of parts. The spores are disseminated by means of remarkable differentiations of the different layers, the growth of particular masses of tissue, or the simple bursting of the outer layer (the peridium). The nature of these processes, which are extremely various in their external appearance, may be understood from two examples. The first example, Crucibulum vulgare1, is selected from the beautiful Nidularie®. The my- celium forms a small white crust of branched hyphae, which extend over the surface of wood. In the middle of the crust the filaments are interwoven into a roundish body, the rudiment of the fructification; this grows by the intercalation of new branches of the hyphae, and gradually assumes a cylindrical form. The outer hyphae form at an early stage yellowish-brown branches, which are again branched and directed outwards, form- ing a dense covering of hair. While the spherical fructification is becoming changed.
