Hypomyces. 



The genus Hypomyces is interesting by the numerous phases of 

 existence through which many of its members pass. Many of the 

 conidial forms of fructification have been described as autonomous 

 species of Mucedineae, under the genera Sepedonium, Verticillium, 

 Dactylium etc., other forms are to be found without special names 

 delineated in Flowright's Monograph of the British Hypomyces (82) 

 and in other places. The most thoroughly examined generical relations 

 are the folowing:
