Differs from C. purpurea, principally in its smaller size (stem fili- 

 form, 10-16 mm. long), head globose, rufous, (| mm.), otherwise like 

 the preceding species. Grows from the ergot of Phraymites communis. 

 which, however, also produces the first-mentioned species. Both these 

 may be raised by cultivation of their sclerotia. which may be lightly 

 covered with earth, kept properly moistened in a flower pot. 



CORDYCEPS, Fries. 



Syst. Myeol. II, p. 324. 



Stroma erect, clavate (mostly), simple or branched, sterile below r 

 bearing the perithecia (and often conidia) above. Perithecia buried 

 or more or less nearly superficial. Asci cylindrical, with 8 filiform, 

 septate sporidia which finally separate at the septa, 



The species of Cordyceps grow for the most part from dead 

 insects, but some also from fungi (species of Elaphomyces). They 

 abound in the tropical regions, but are found also in the temperate 

 zones. Their conidial stage is represented by the various species of 

 Isaria.

 sul (inflated at the apex. Sporida linear, immature. 



On dung of birds, probably from the remains of insects eaten.
