PHYSIOLOGY AND MORPHOLOGY OF CALIFORNIA HEPATIC I9 
telst des Stoffwechsels des Endophyten in haltbare Reservestoffe 
umgewandelt und aufgespeichert werden, von denen namentlich 
die auffallend grosse Oelmenge dem Prothallium die Fahigkeit 
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 Fossom- 
bronza and Aneura at a certain stage in the development of the 
endophyte there is a minimum quantity of these products within 
the host cells containing hyphe 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 were /7mdbriarza, Hegatella 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 
olneyz Aust., the septate hyphze of which produce at the ends 
of lateral branches, globular clusters within which are produced 
numerous dark spore-like cells bearing some resemblance to 
those of the Tilletiaceze. He has found the same parasite in 
A. ravenellit Ala. (Mohr.) and the same or one very similar in 
A.hallit 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 (Conocephalum conicum) is described by 
Howe’ as growing in moist, deeply shaded places, especially
