in Figs. 132, 133, and 134 (pp. 304, 305, and 307). Upon the dung 

 in the crystallising dish of Fig. 132 a great many fruit-body rudi- 

 ments made their appearance and a few of them, more favoured 



than the rest, have developed 

 into young fruit - bodies. 

 These have a soft woolly 

 aspect, owing to the presence 

 of white fibrillar scales upon 

 their pilei ; and their stipes, 

 altliough at present very 

 short, are about to elongate 

 rapidly. In Fig. 133 the 

 fruit- bodies are in various 

 states of maturity. Their 

 pilei are grey owing to the 

 presence of black spores 

 upon the gills, and the 

 fibrillar scales are no longer 

 so conspicuous. In Fig. 134 

 is to be seen the largest fruit- 

 body which I have succeeded 

 in raising under cultivation. 

 Its pileus is rapidly expand- 

 ing and is about to begin to 

 liberate spores. The fuga- 

 cious scales on its left side 

 have been rubbed off by 

 accident, thus exposing the 

 gills which are splitting 

 downwards radially from the

 grown in complete darkness. Pure 

 culture on a sterilised horse-dung ball, 

 from spores originating at Birmingham, 

 p]ngland. Note the woolliness of the 

 stipes. The full-grown but as yet un- 

 expanded pileus, owing to the unusual 

 narrowness of the gills, is much thinner 

 and more pointed than a pilevis of equal 

 height developed in the light (c/. 

 Fig. 1.37). Its greyness shows that 

 spores have ripened upon its gills and 

 that it is therefore quite fertile. Natural

pileus-periphery to the disc. 

 There were loose white fibrillae on the surface of the stipe, but they 

 are not visible in the photograph. 



In Volume II, I pointed out that the tiny wild fruit-bodies 

 occurring in crevices between, and under, horse-dung masses in 

 fields in England, which Massee considered to belong to Coprinus 

 radiatus, are in reality nothing but dwarf fruit-bodies of C. lagopus ;
