 correct, so far as the branching is concerned, had the chief and oldest 



Fig. 187. — Coprinus macrorhizus. Branching of the pseudorhiza. The dotted line 

 indicates the general level of the substratum. A, a young fruit-body with 

 a very stout pseudorhiza likely to produce new fruit-bodies when the first has 

 been exhausted. B, fruit-body begiruiing to shed spores, having a pseudorhiza 

 which has already given rise to the rudiments of a number of new fruit-bodies. 

 C, a very stout pseudorhiza which gave rise to a large subaerial fruit-body which 

 shed its spores, died down, and is now represented merely by a stump. The 

 pseudorhiza subsequently gave rise to numerous rudiments of new fruit-bodies, 

 four of which are now developing normally. D, the terminal fruit-body was 

 injured and has ceased to develop, and new fruit-bodies are arising on the 

 pseudorhiza. E, the pseudorhiza which is springing from a straw, has a terminal 

 fruit-body and two lateral rudimentary ones. Natural size.

 the pseudorhiza : but this was not done. Weir seems to have 

 combined two stages of development in a single drawing. From 

 Weir's illustration, as it stands, one would judge that the main axis
