of a worm which was freely exposed in the liquid drop that had 

 accompanied the sporangium during its flight. Thus conclusive 

 evidence was obtained that Nematode larval worms may occasionally 

 be shot through the air along with a Pilobolus projectile. 



In 1772 Scopoli ^ recognised the true affinities of Pilobolus, as 

 is indicated by the fact that he gave the name Mucor obliquus 

 to the species which he studied. The first good description 



Fig. 5. — Pilobolus (Kleinii ?). A photomicrograph of a 

 group of fruit-bodies growing on dung in the 

 laboratory, showing black sporangia, subsporan- 

 gial swellings, stipes, and drops of mucilaginous 

 fluid excreted on the swellings and stipes. Photo-

of the genus was given in 1784 by Tode,^ who named one of 

 its species Pilobolus crystallinus — a name which is still retained. 

 Among the later observers who contributed most to our know- 

 ledge of the species of Pilobolus are Persoon,^ Montagne,* Cohn,^
