Prototrichia, it wo uld a appear to be far removed from the genus 
Trichia in all other respects; on the other ands the brush-like 
processes in C. depressa, so much resembling the otherwise unique 
habit of Prototrichia flagellifer, the very s similar mode of attachment 
of the capillitium, and the identity in structure of the sporangium- 
wall, point to a near affinity between these two species. The | 
spores of Prototrichia are precisely similar to spt of C. metallica, 
and it would seem to be the most natural arrangement to unite 
P; flageliifer, C. oT and C. depressa under the genus Cornuvia,
