In fructification a stalk rises from the body of the insect or larva and in the enlarged extremity of this the perithecia are grouped. The stroma is vertical and fleshy, head distinct, hyaline or colored; sporidia repeatedly divided and sub-moniliform.
Cordyceps Herculea. (Schw.) Sacc.
Figure 491.—Cordyceps herculea. Showing the grub upon which this species grows.
Herculea is so called from its large size. The halftone will readily identify this species. The plant is quite large, clavate in form, the head oblong, round, slightly tapering upward with a decided protuberance at the apex, as will be seen in Figure 491. The head is a light yellow in all specimens I found, not alutaceous as Schw. states, nor is the head obtuse. I found several specimens on a sidehill in Haynes's Hollow in August and September, all growing from bodies of the large white grubs which are found about rotten wood. They were found during wet weather. They were identified by both Dr. Peck and Dr. Herbst.
