DIAGNOSTIC CHARACTERS. 



I) 



The Fungi represented in the Models are the larger forms. 

 They belong to the several Orders of which the diagnostic characters 

 are given in the following key : — 



CLASS I. BASIDIOMYCETES. — Spores borne on more or less club-shaped 



cells — basidia. 



Sub-Class 1. Hymenomycetes. — Spore-bearing surface or hymenium ex- 

 posed during development. 



Order I, Agaricinece. — Hymenium spread over the surface of lamellae 

 or gills. 

 ,, II. Polyporece. — Hymenium lining the interior of tubes. 



III. Hydnecc. — Hymenium spread over spines. 



IV. ThelephorevE. — Hymenium smooth and horizontal. 

 V. Clavariece. — Hymenium smooth and vertical. 



„ VI. Tremellinece. — Hymenium covering entire surface. Gela- 

 tinous. 



Sub-Class II. Gasteromycetes. — Spore-bearing surface, or hymenium 

 enclosed until maturity. 



Order VII. Phalloidece. — Hymenium enclosed in a volva with a middle 

 gelatinous layer — at maturity volva ruptured and hy- 

 menium exposed. 



,, Vlll. Lycopcrdacecc. — Hymenium enclosed in a double dehiscent 

 pcridium — spores borne on a capillitium. 



„ IX. SclerodermecE. — Hymenium enclosed in a single, dehiscent, 

 thick peridium opening at the apex irregularly ; capilli- 

 tium absent or scantj". 



„ X. Hymenogastrca. — Hymenium enclosed in a single indc- 



hiscent peridium. Capillitium absent. Subterranean. 



CLASS II. ASCOMYCETES. — Spores borne zi;/V/i(« more or less tubular cells — 



asci. 

 Sub-Class I. DiscoMYCETES. — Sporc-bcaring surface more or less basin- 

 shaped, exposed. Bright coloured. 

 „ 11. Pykenomycetes. — Spore-bcaringsurface flask-shaped, spores 



escaping through an ostiole. Black. 

 „ 111. TuBERACE>E. ^Spore-bearing surface enclosed in an inde- 



hisccnt peridium. Subterranean. 



CLASS III MYXOMYCETES. — Consisting of masses of free, moving proto- 

 plasm, Plasmodia, forming sporangia enclosing large 

 numbers of spores.
