THE CARPOPHORE 29 Fig. 14.—Clav- ate stroma of Cordyceps. the fructifying surface is sufficiently raised above the soil to attain its development (Fig. 14). The carpophores vary not only in length for the same species, according to circumstances, but also in form, according to the species. In some it is simple, and in others branched, but the receptacles are always densely accumulated about the apices in this genus of Cordyceps. Hence we recognise again that a carpophore is a contrivance which is resorted to in order to bring the fructification into the air and light, and is lengthened or shortened in con- formity with that object. In the genus Xylaria the form of carpophore is similar, but its texture different. The colour is normally black exter- nally, white and corky within, and it is wholly tough and hard. The species grow on putrid wood and rotting leaves. In an allied genus, Thamnomyces, the carpophore is very long and thin, often like horse hair, running amongst dead leaves and vegetable debris. It is notable how some of the simplest forms of carpophore are repeated in different groups of Fungi far removed from each other in structure. This is the case where the whole Fungus is club- shaped, as it is in Clavaria pistillaris, and again, even as to colour, in Xylaria involuta. Others of a smaller size, but of a like form, will be found in Clavaria ligula, Leptoglossum olivaceum ; Xylaria rhopaloides; Geoglossum hirsutum, and Hypocrea ophioglossoides. No one can doubt, after tracing the gradations of form in Xylaria, that the spherical carpophores, not only in Xylaria, but also in Daldinia, Glaziella, Sarcoxylon, and the Sphaeroxylon section of Hypoxylon, are of the same character, and have a similar purpose to the foregoing (Fig. 15). Possibly the globose forms may primarily serve to expose the largest surface of immersed receptacles
