C. rhynchoticola surrounds the cadavers with a loose hyphal felt, clings firmly to the substrate, and spreads out on it somewhat as in Fig. 168. The necks of the solitary, flask-shaped perithecia project over the stroma about mm. In the higher forms, as in all the Hypocreales, there occurs the differ- entiation of the stroma into fertile and sterile parts; the infected animal is penetrated in all directions by hyphae, mummified, and changed into a sclerotial structure from which later grow the perithecial stromata. In C. norvegica, they form a narrow clavate structure up to 20 cm. long on whose whole surface are imbedded the perithecia. It suggests Clavaria pistillaris of the Basidiomycetes. In the neighboring collective species, C. militaris, and in C. on the fructifications of Elaphomyces muricatus, these clubs are again differentiated in a sterile base and fertile top (Fig. 169). In still others, especially in tropical.
