4. Hyphomycetes. Spores naked, variously seated on con- 

 spicuous threads, which are rarely compacted ; mostly small in 

 proportion to the threads. 



II. Sporidiiferi (Sporidia in sacs). 



5. Physomycetes. Fertile cells seated on threads, not com- 

 pacted into an hymenium. 



6. AscoMYCETFs. Asci formed from the fertile cells of an 

 hymenium. 



These Orders are again divided into the following Sub- 

 orders : — 



I. Hymenomycetes. • 



A . Hymenmm itiferior, except in resupinate forms. 



Suborder 1. Agaricini. Fructifying surface lamellose. 



2. Polyporei. Fructifying surface porose or tubulose. 



3. Hydnei. Fructifying surface clothed with prickles. 



4. Auricularini. Fructifying surface even, without folds, 

 tubes, prickles, etc. 



B. Hymenium superior or circumambient. 



5. Clavariei. Clavate, or variously branched, rarely lobed or 

 gelatinous. 



6. Tremellini. Lobed, convolute, or disciform, gelatinous ; 

 fertile threads not compacted into an hymenium. 



II. Gastebomycetes. 



A. Hymenomycetous. 



Suborder 1. Podaxinei. Stipitate, subclavseform ; hymenium 

 convolute, enclosed in a volva-like peridinm, withering or entirely 

 drying up. 



2. Hypjog^i. Subterraneous; naked or invested with a con- 

 fluent, or very rarely a distinct peridium. 



3. Phalloidei. Hymenium passing into a diffluent mass. 



4. Nidulariacei. Peridium enclosing one or more distinct, 

 free or stipitate sporangia, which contain a mass of cells, of 

 which the central ones produce spores, or sporophores. 



B. Coniosjjerv/ous. 



5. Trie hog astres. Plant at first cellular ; hymenium drying
