Pileate and Clavate Tribes of Hymenomycetous Fungi. 89 



was published in 1836. Under Ay. prunulus, p. 'J 6, I have 

 given the following description : " Gills covered with very mi- 

 nute conical papillae, ending in four spiculae. Sporules often 

 seated upon the spiculae." The fructification of Ay. cermius, 

 Ay. bifrons, Ay. gracilis, and Ay. disseminatus is described as 

 quatcrnate. In Ay. semiovatus the reproductive bodies are 

 described as quaternate, the major axis perpendicular to the 

 gills. Under Ay. panuoides it is remarked that " the gills are 

 beset with minute hairs, upon which the spornles are often 

 seated, as in Ay. prunulus." 



A paper by M. Montagne* was read before the Academy of 

 Sciences at Paris on January 2, 1837> in the report of which 

 are the following observations : u Des planches dessinees a la 

 chambre claire du microscope compose de M. Charles Cheva- 

 lier sont destinees a montrer tous les degres par lesquels passe 

 une sporidie avant de se detacher de Putricule ou elle a pris 

 naissance. Avant sa chute, cette sporidie est ordinairement 

 supportee par un pedicelle plus ou moins long, qui se forme 

 peu a peu, quoique cVune maniere tres prompte en egard a la 

 vie ephemere de ces vegetaux, aux depens du sommet de Putri- 

 cule, qu'elle chasse devant lui." The latter sentence is so con- 

 fused that the reporters meaning is not clear; but judging from 

 the observations on the evolution ofBotrytis Bassianaf, with 

 which it is expressly compared, it should seem that M. Mon- 

 tagne considers the reproductive bodies as essentially internal ; 

 in other words, as sporidia and not spores. tt Les sporidies," 

 he says, speaking of Bot. Bassiana, " se forment a l'interieur 

 des filaments, et en sortent et se groupent symmetriquement 

 a Pextremite des ramules par un mecanisme que nous avons 

 tente d^expliquer. Elles s'echappent de Fextremite des fila- 

 ments et des rameaux par un mecanisme particulier qui con- 

 sisterait en ceci. Chaque seminule arrivee a Fextremite du 

 tube, avant de s*en separer, en emprunterait une seconde en- 

 veloppe qu'elle conserverait." 



It is clear that when the notices given above from the En- 

 glish Flora were published, I was not satisfied with the cha-
