Rcz'isious of Some Plant Phyla 25 



Family iii. Sclerodermataceae. Spore-fruit often with a 

 stalk-like base; no columella; gleba powdery, often with sporan- 

 gioles. Scleroderma, Pisolithus. (Pf. I, i**, 329.) 



Family 112. Podaxaceae. With columella; gleba more or less 

 lamellate. Secotinm, Pod axon. (Pf. I, i**, 329.) 



Order Lycoperdales. Puff-balls. Spore-fruit fleshy when 

 young, closed, subterranean at first, later superficial, internally 

 filled with irregular spore-bearing canals, or a spore-bearing 

 tissue; capillitium present. 



Family 113. Lycoperdaceae. Spore-fruit sessile or short- 

 stalked, filled with spore-bearing canals. Lycoperdon, Calvatia, 

 Bovista, Geaster. (Pf. I, i**, 315.) 



Family 114. Tylostomataceae. Spore-fruit long-stalked, when 

 young filled with spore-bearing tissue. Tylostoma, Battarca. 

 (Pf. I, I**, 342.) 



Order Nidulariales. Bird-nest Fungi. Spore-fruit spherical, 

 top-shaped, or cylindrical, leathery, containing one or more spore- 

 bearing cavities, which by deliquescence of the surrounding tis- 

 sues become peridioles (" sporangioles "). 



Family 115. Nidulariaceae. Spore-fruits small, each with sev- 

 eral peridioles, sessile upon the ground. Nidularia, Crucibulum, 

 Cyathiis. (Pf. I, i**, 326.) 



Family 116. Sphaerobolaceae. Spore-fruits spherical, each 

 with one spherical peridiole which is ejected at maturity. 

 Sphaeroholus. (Pf. I, i**, 346.) 



Order Phallales. Stink-Horns. Spore-fruit fleshy, when 

 young closed, subterranean at first, internally containing a circu- 

 lar spore-bearing cavity, later developing a stalk which ruptures 

 the peridium, exposing the spores; no capillitium. 



Family 117. Phallaceae. Spore-bearing stalk cylindraceous, 

 hollow, capped by the spore mass. Mutinus, Ithyphallus, Dicty- 

 opJwra. (Pf. I, I**, 289.) 



Family 118. Clathraceae. Spore-bearing stalk ovoid and retic- 

 ulated, or cylindrical and branched above ; spore mass capitate or
