(fig. 3) ; other specimens, especially before they are ripe, have 

 smooth stems (fig. t2). This solid stem, which is variable m length, 

 according to the depth of the larva under the ground, is sterile, 

 the spore-producing area being the globose capitulum (fig. la). 

 Several specimens resembled Greville's C. gracilis * which is 

 now considered merely a variety of eiitomorrhiza (fig. Ih). The

clubbed erect body is reddish browii, and in some darkened 

 at the capitulum, others have rusty brown capitula, whilst 

 yet others are yellowish, resembling the variety recorded 

 by Greville from Shetland. Internally the globose head con- 

 tains a number of cavities, or perithecia, when ripe, em- 

 bedded in the soft stroma of the capitulum. Each cup-shaped 

 perithecium opens to the exterior by a small round aperture, 

 when the spores contained in them are ripe. There are 

 eight thread-like filaments in each perithecium, which break 

 up into a number of oblong spores. These spores are then 

 passed out of the openings on to the soil and in the air, a
