Immature fungus showing development of spores. 

 Sporophaga cyanea, gen. et sp. nov. 



(a) Optical section of spore of Balsamia vulgaris in the early 

 stage of its development, (b) Section of the same showing the 

 membranous investments of the spore, (c) ^a/^awm spore in a 

 more advanced stage of development, (d) Ascus with spores of 

 the host-plant; some of the spores already ruptured and the parasite 

 set free within the ascus. (e) Group of parasites within a spore 

 of the host, (f ) Two parasites with hyphae within a spore of 

 the host, (g) Isolated parasite showing a double investment of 

 the same, together with its septate hyphae, the hyphae having a 

 branched terminus.

 paraphyses; cell-wall of the perithecia enclosing parasitic 

 spores, (b) Perithecia in different stages of development, one 

 still destitute of spores; the asci of the host-plant faintly shown, 

 (c) Isolated spore greatly magnified. Spores colored black for 

 convenience, in life as in ijr.
