The mycelium is perennial in the host (see Plowr. 89 *°) and the 

 spores are found in the flowers May— July.

The mycelium penetrates the whole 

 plant causing several deformations, the 

 stems get shorter and remain upright 

 long after the fading of the sound stems. 

 Species of Carex which are otherwise 

 heterostachuous grow homostachuous on 

 account of the attack of the fungus or all flowers grow hermaphro- 

 dite; such plants have been described as Carex Linkii Thomas.

On Astragalus have hitherto only been found resting-spores which 

 fill the pods causing them to be shorter and thicker than the normal 

 ones; on Trifolium has hitherto only been found the conidial stage 

 which attacks the anthers of all flowers of the head; according to 

 Clinton's account (04 ''^^) we might, however, be justified in con- 

 sidering it a single species or, at any rate, biological forms of a single 



species.
