Since in such cases the sporophore bears sexual cells, they may be conveniently termed gametophores.
Us to cases where the main mass of the sporophore forms a supporting tissue of closely crowded or interwoven hyphae, the sporogenous terminal parts of the hyphae being found at the periphery or apical regions only.
Here we have the cushion-like type (stroma) of Nectria and many Pyrenomycetes, the clavate "receptacle" of Clavaria, &c., passing into the complex forms met with in Sparassis, Xylaria, Polyporei, and Agaricini, &c. In these cases the compound sporophore is often termed the hymenophore, and its various parts demand special names (pileus, stipes, gills, po--es, &c.) to denote peculiarities of distribution of the hymenium owlthe surface.
By this means the temperature of the sporophore is raised and the difference between it and the surrounding air may be one of several degrees.
Most of Basidiomycetes are characterized by the large sporophore on which the basidia with its basidiospores are borne.
