ing spiculae, but without any reproductive bodies. The spores 

 which had fallen on the veil were considered by him as male 

 organs, an error pointed out by Bulliard in 1791. 



In 1791 Bulliard* distinguished two different kinds of 

 bodies in the hymenium of Agarici, Boleti, and Thelephora by 

 the name of spermatic vessels and seeds. The utricles on the 

 gills of Coprini are an instance of the first ; and though ana- 

 logous bodies, as will be seen hereafter, exist in Boleti, &c., 

 he appears often to have called the true reproductive bodies 

 by the same name, and sometimes perhaps the fringes noticed 

 by Micheli. The true sporidia, or more properly speaking- 

 spores, he figures as superficial, tab. 1. fig. hi. 10. 11, tab, 2. 

 fig. xi. p ; and at fig. ix. k the spores of Auricularia phylac- 

 teris are represented (under the name however of spermatic 

 vessels) as seated four together upon a common peduncle. 

 The same structure is also given under Auricularia caryophyl- 

 lea, tab. 483. 6 & 7« S. Indeed, he says, "Les champignons 

 dont nous venous de parler ont presque toutes leurs graines 

 inserees a des filets extremement courts/ 3 (p. 50.) Such are re- 

 presented tab. 2. fig. 1. F. G. In fig. vii. and viii., which re- 

 present the structure of Boletus and Fistulina, superficial grains 

 are figured, which in the former case probably consist partly 

 of the spores and spore-bearing cells, in the latter possibly of 

 the spores only. No analysis is given of Clavaria. The re- 

 marks about spermatic vessels in that genus apply principally 

 to Sphceria and Hypoxylon. 



In 1796 Persoonf described the quaternary arrangement of 

 the reproductive bodies of Corticium caesium (Thel. ccssia, 

 Nees), comparing it with the similar arrangement in Coprini. 

 It is highly probable that he considered them as superficial. 



Up to this time all seem agreed that the reproductive bodies 

 are superficial. Miiller and Bulliard figured them as sup- 

 ported by peduncles ; and Bulliard and Persoon detected the 

 quaternary arrangement in Thelepliora. Modern notions of 

 the structure of the hymenium appear to have arisen from two 

 important memoirs of Link, to which we have now to call at-
