PLECTOBASIDIINEAE. 

 (SCLERODERMINEAE.) 



Peridium subglobose, obovate, clavate, or variously shaped, sessile, 

 stipitate, or prolonged into a stem-like base, consisting of one or more 

 layers, dehiscing by the gradual falling away of portions of the peridial 

 walls, by the rupture of the exoperidium or endoperidium in an 

 irregular, or circumscissile manner, or by a well-defined apical aper- 

 ture. Gleba not divided up into cells, with, or without, a sterile 

 base, and traversed, or not, by sterile veins, which rarely break up 

 into peridiola, finally breaking down into a powdery mass, rarely 

 becoming slimy. Basidia clavate to pear-shaped, bearing 2-12, pedi- 

 cellate, or sessile, apical, or lateral spores, irregularly arranged, 

 rarely tufted, and not forming a distinct hymenium, intermixed, or 

 not, with capillitium threads. Spores white, or coloured, subglobose, 

 or elliptical, echinulate, verrucose, reticulate, or smooth. Subter- 

 ranean, or superficial. 



SCLERODERMATACEAE. 



Peridium subglobose, turbinate, or irregularly pear-shaped, sessile, 

 or prolonged into a stem-like base, consisting of one or more layers, 

 fleshy, leathery, or membranaceous, dehiscing in an irregular manner. 

 Gleba traversed by sterile veins. Capillitium rudimentary. Spores 

 coloured, globose, or elliptical, echinulate, verrucose, reticulate, or 

 smooth. Subterranean, or superficial.
