STROPHARIA SEMIGLOBATA 



345 



FIG. 122. Stropharia semiglobata. An area of the hymenium 0-5 mm. long and 0-33 mm. wide, drawn after spore- 

 discharge had ceased, showing the exact number and arrangement of the spores which were left adhering to the hymenium. 

 The spores shown in black were fully pigmented, those shaded heavily with dots partially pigmented, and those shaded 

 lightly with dots colourless. The hymenium is made up of : exhausted basidia, m, each with four sterigmatic stumps ; 

 paraphyses, n ; and seven cystidia, k, irregularly scattered. There are several heaps of four spores, each heap represent- 

 ing the product of a single basidium : a, 6, c, d, e, f, g, h, i, groups of immature spores ; j and I, groups of fully pig- 

 mented spores. The waste sporos form just under 8 per cent, of all the spores which were produced on the whole area.
