ACOTYLEDONS. FUNGI. 



ble substances, rarely (never ?) aquatics, and scarcely ever 

 green ; filamentous, gelatinous, spongy, corky, coriaceous, 

 fleshy, or membranaceous. In the larger sense of the word, the 

 whole may be considered as fructification, since distinct from 

 it there is no stem, there are no branches, no leaves, no frond, 

 and very rarely a simple crustaceous base. The seeds or spo- 

 rules are either internal as in Sphceria, Bovista, or external 

 as in Agaricus, &c. After being once dried they do not re- 

 vive by the application of moisture, like the greater number 

 of plants in this class; and, generally speaking, they are of 

 very short duration, soon decaying, and frequently becoming 

 putrid in decay. 



Div. I. ANGIOCARPI. Seeds or sporules contained within the Fun- 

 gus, which is closed, at least in an early stage, on all sides. 



SECT. I. SCLEROOARPI. Fiwgi of a hardish nature externally, 

 internally soft. 



1. SPH.ERIA. 



Receptacle (or fungous substance) varying in form, or none. 

 Sphcerutes roundish, when dry generally hollow ; when moist 

 filled with seeds included in a gelatinous substance. 



* Receptacle of the spherules elongated, clavate.
