Coniomycetes from Konis, Gr., dust, the dust-like spores forming 

 the chief character. 



Hyphomycetes from Huphe, Gr., a woven mass of threads. 



Physomycetes from Phuske, Gr., a vesicle, or bladder where the 

 fruit arises from the tip of a thread, penetrating into the vesicle, 

 which forms a covering for the fruit. 



Ascomycetes from Askos, Gr., a sac, where the fruit is formed 

 within asci. 



Hymenomycetes. The plants of this family possess a floccose 

 mycelium, either giving rise at once to a distinct hymenium, or 

 producing a variously shaped, naked, or volvate receptacle, even, 

 or bearing on its upper or under surface various folds, plates, or 

 prickles, clothed with fertile hymenial cells. 



Hymenium spread over distinct plates 

 or gills. 



Hymenium lining the cavity of tubes or 

 pores, which are sometimes broken up into 

 teeth, or concentric plates. 



Hymenium spread over spines, teeth, 

 papillse, &c, not lining impressed tubes, &c. 



Hymenium confluent with the hymeno- 

 phore, at first even, or rarely veined. 



Hymenium scarcely distinct from the 

 hymenophore, vertical, amphigenous, reach- 

 ing to the apex, even or at length wrinkled. 

 Never incrusting or coriaceous. 



Whole plant gelatinous, except occasion- 

 ally a nucleus. Sporophores large, simple 

 or divided, spicules elongated into threads.
