middle.

stage of the slime-moulds. 

 Pli'catc: folded like a fan. 

 Plum'bcoiis: lead-color, bluish-gray. 

 PocuUform : cup-shaped. 



Pore: in the Pyrenomycetes same as ostiole or ostiolum. 

 Porrcct : stretched horizontally. 

 Posterior: in case of the gills of the Agarics, denotes the point next to 



the stem; that is, the posterior end is that next to the stipe. 

 Pro'tof^lasDi: the living nitrogenous mass of the cell which is the physical 



basis of life. 

 Pubes'cent : with short hairs. 

 Pul'i'inatc: cushion-shaped. 

 Punctate: dotted. 



Pus'tular: with elevations like blisters or pustules. 

 Putrescent : soon decaying.

 Pycnidium (pi. pycnidia) : a peritheci'mi-like ascocarp or body in which 



sporules are produced.

 Remote' : said of gills that do not reach the stem. 

 Rc'pand: wav}'. 



Re' plicate : folded back upon itself. 

 Resu'pinate: attached by the back, herce the hymenium facing outwards; 



in this case there is no stem to the fungus which is spread o\er the 



matrix ; applied to the Polypori, etc. 

 Re'^''olutr: rolled backward.

 Scah'roui- with a rough surface. 



Seis'sile: easily split ; said of gills readily separable into two plates. 

 Sclero'tium : a hard l)lack mass, sometimes resembling a tuber, which is 



the dormant or resting vegetative stage of some fungi, and fnun 



which later sporophorcs may arise. 

 Scorhic'ulatc : with small ))its or furrows.
