OMPIIALIA FLAVIDA

The Origin of the Stilbum-bodies. — As first pointed out by 

 Maublanc and Rangel/ the s/i/6Mm-bodies and the Omphalia sporo- 

 phores show marked resemblances. Among these resemblances are 

 the following. (1) The stalk and head of a stilbum-hody correspond

Fig. 211. — Omphalia flavida. Basidiospores and their germination in a malt 

 solution (2-5 per cent.). A: spores freshly immersed, some in lateral 

 view, others in face view. B : spores after being immersed 36 hours ; 

 they are now much swollen. C : spores germinating after 42 hours 

 immersion; the germ-tubes have just been produced. D: other spores 

 with longer germ-tubes, the seven upper ones after 42 hours immersion, 

 the two lower ones after six days ; the spores cannot now be distinguished 

 from the germ-tubes or mycelium ; the hyphae are filled with fine cyto- 

 plasm, and some of the sporelings have developed one or two septa.

respectively to the stipe and pileus of the agaric. (2) The stalk of a 

 stilbum-hody and the stipe of the agaric are both clothed with 

 short simple hair-like outgrowths. (3) The palisade cells at the 

 top of the pileus of the agaric correspond to the swollen cells which 

 surround the oblate-spheroidal part of the head of a stilbum-hody, 

 but differ from them in being fimbriate and in not producing long
