Fig. 96. — Coprinus lagopus. Union of three monosporous mycelia to form a 

 compound mycelium. Drawing made nine days after sowing the spores in 

 a shallow drop of horse-dimg fluid. A, three basidiospores a, b, and c which 

 have germinated and produced three mycelia ; d, a germ-tube vesicle ; e, a 

 hypha uniting the mycelium produced by the spore a with that produced 

 by the spore b. B, the three spores of A and their m.ycelia shown on a 

 smaller scale : the spores a, b, and c have given rise to three mycelia a, b and 

 c respectively ; d, a hypha bearing oidiophores and oidia ; the three mono- 

 sporous mycelia have become unite! to form a single, finely netted, com- 

 pound, haploid myceliiun ; most of the lateral hyphae have grown toward, 

 and have met and fused with, another hypha, and freely-ending hyphae, 

 as at e, are few in number ; where two hyphae have crossed near to one 

 another, as at / and g, a bridging hypha has been put out from one to the 

 other ; in some places, as at h, a, hypha has crossed over another hypha 

 and has fused with it after making a growth -curvature through 180'^.
