This wonderful fungus has a number of synonyms, no doubt owing to 

 the different stages it passes through to reach perfection. Secale cornuti 

 was one of the first names before the life history was known. It has been 

 used in medicine from time immemorial, and is still used to some extent. 

 The fungus is getting scarce. I remember some years ago when it was 

 quite common on rye, even to the detriment of the farmers and millers. 



It converts the rye grains into a useless mass for flour. 



C. microcephala. Tul. 



Stroma, horn-shaped, cylindrical, black externally, whitish 

 internally.
