PHYSIOLOGY AND MORPHOLOGY OF CALIFORNIA HEPATIC^ 1 9 



telst des Stoffwechsels des Endophyten in haltbare Reservestoffe 

 umgevvandelt und aufgespeichert werden, von denen namentlich 

 die auffallend grosse Oelmenge dem Prothallium die Fiihigkeit 

 verleiht, in dem sandigen Boden auch wahrend der Sommerhitze 

 und der Winterkalte von Austrocknung bewahrt zu bleiben." 



As already stated, the author has found, in the case of all 

 infected forms thus far investigated, oil and of necessity 

 albumen, in the living cells of the gametophyte. In F'ossojii- 

 bronia and Anctira at a certain stage in the development of the 

 endophyte there is a minimum quantity of these products within 

 the host cells containing hyphte and a maximum amount of 

 these same products within the cells of the fungus. The result 

 is the death of the host or, at least, a very serious check to its 

 development, resulting in small sickly plants. In such a case 

 we cannot possibly regard the food products derived from the 

 gametophyte as reserve materials later to be given up by the 

 fungus as nourishment to further growth of the host. 



The only forms examined not showing harmful effects from 

 association with a fungus v^^ere Fimbriai-ia^ Fegatella and 

 Anthoceros. Of the first and the last, only a very limited 

 amount of infected material was found, consequently little light 

 can be thrown upon actual relation of host to endophyte. Howe ' 

 has reported an endophytic fungus associated with Anthoceros 

 olneyi Kxisi.^ the septate hyphte of which produce at the ends 

 of lateral branches, globular clusters within w^hich are produced 

 numerous dark spore-like cells bearing some resemblance to 

 those of the Tilletiacege. He has found the same parasite in 

 A. ravenellii A.\2L. (Mohr.) and the same or one very similar in 

 A, hallii Aus. He regards this fungus as a parasite, though no 

 detailed account is given relative to the character of the asso- 

 ciation of the two. 



DEVELOPMENT OF FRUITING ORGANS OF FEGATELLA CONICA 



IN CALIFORNIA. 



Fegatella conica [Conocephaluvi contctmi) is described by 



Howe^ as growing in moist, deeply shaded places, especially
