Fig. 49. — Plutcvs cervinus. A, surface view of a gill taken from a very .young fruit-body (A in Fig. il) : c, cystidia still 

 with rounded apices ; 6, basidia protruding beyond, and thereby largely covering, the paraphyses. B, a vertical transverse 

 section tlirough parts of two gills of the same fruit-body (A in Fig. 47) : ?, the intcrlamellar space between the gills ; h, the 

 hymeaium ; s, the subhymenium ; t, the trama ; c, young C3'stidia ; 6, basidia ; p, paraphyses. C, surface vio.v of a gill of a 

 fruit-body sliortly before the opening of the pileus (B in Fig. 47) : c, cystidia, already with apical prongs and fully developed ; 

 b, basidia. D, a vertical transverse section through three gills of the same fruit-bodv (B in Fig. 47) : h, the hymenium ; s, the 

 sub-hymcnium ; t, the trama ; i i, interlamellar spaces into which the c.ystidia, r, project (c/. Fig. 48) ; b, basidia ; p, paraiihyses. 

 E, a vertical transverse section tlirough two gills of a fully expanded fruit-body (C or D in Fig. 17) during the spore-discliarge 

 period ; in the centre a wide interlamellar space into u'hich spores are being discharged ; /i, the hymenium ; s, the subhyme- 

 nium ; /, the trama ; c, cystidia now projecting freely into the widened interlamellar space ; "ft, basidia ; />, paraiihyses ; 

 a basidium near the top of the right hymenium is about to discharge its last spore, as is indicated by the size of the drop of 

 fluid already excreted at the spore-hilum. The arrows directed away from the hymenium indicate the trajectories described 

 by some of the spores when shot violently from their sterigmata." The spores" falling in the middle of the interlamellar 

 space have been shot away from the hymenium on parts of the gills which are higher than those here shown : two of them 

 (arrows Nos. 2 and G from the left) still retain the drop of fluid which was discharged with them; from other sjiores the 

 drop has already evaporated ; other spores (arrows 7 and U from the left) are already drying up and becoming boat-shaped.
