of development being rather different from what is the case in 

 Grijfithsia globifera I again examined my material, and I found 

 that it verified the observation made by Lewis. Fig. 1.93 b and 

 c shows two young protecting cells. They grow out from the 

 mother-cell in a precisely similar method to the basal cells in 

 the tetrasporic branch. Lewis describes it in this way (1. c, 



Fig. 193. Gn'ffithsia globifera (Harv.) J. Ag. a, base and top of two cells 

 of tetrasporic plant showing the large porus ; upon the lowermost cell two 

 tetrasporic branches and two involucral cells, b and c, young involucral 

 cells, e, involucral . cell with swollen base, d, young tetrasporic branch, 

 f, young cystocarp with involucral cells, {a, about 80 : ], b — f, about 150: 1). 



p. 664): "On the side toward the stalk-cell the cytoplasm of 

 the mother-cell is produced into a rather narrow strand, which 

 meets a similar strand from the stalk-cell at the point where the 

 callus-like plugs are developed". A few times I have found the 

 basal narrow strand somewhat swollen (Fig. 193 e), but I have
