Buller, A. H. R., The Fruit-Body Mechanism oi Bolbitius. 

 (Trans. Brit. Myc. Soc. IV. p. 235-238. 1813.) 



The author examined the method of spore-production and spore- 

 discharge in Bolbitius, and compares it in detail with that of Copri- 

 nus, which he has described in previous publications. The mechanism 

 of Bolbitius differs completely from that of Coprinus, the liquefaction 

 of the gills in particular being a post-mortem change, and not 

 connected with spore-discharge. 



The structure of the hymenium is also different in the mono- 

 morphic basidia and absence of cystidia, and in the basidia in any 

 small area developing and discharging their spores in succession. 

 It is concluded that Bolbitius and Coprinus are not so closely related 

 as has hitherto been supposed. E. M. Wakefield (Kew)

S. mucori)ium, Harz., var. botryoides, Elliot, was fonnd on soil 

 cultures containing decomposing animal matter and not on Muco- 

 rinae. The variety differs from the type in the long, branched coni- 

 diophores, and in the colour of the conidia, which is never deeper 

 than pale buff. E. M. Wakefield (Kew).
