IV. INTRODUCTION. 



Tribe III. MITRATI. 



Eeceptacle bullate, pileiform, margined. Hjinenium superior, never closed ; reproductive bodies, sporidia packed 

 in asci or thecse. 



These are what are called the ElveUaceous family, among them the esculent Morel and 

 Hehella crispa are excellent articles of food, the Morel being of importance even in a com- 

 mercial point of view. 



1. MOECHELLA. — Receptacle pUeate. Hymenium costate, lacunose. 



2. HEL^TSLLA. — Eeceptacle pileate, deflexed, lobed. Hymenium even. 



3. VEEPA. — Receptacle conico-deflexed, equal. Hymenium even or \vi-iukled. 



•i. LEOTIA. — Eeceptacle capitato-pileate, the margin revolute, bearing asci beneath as well as above. 

 5. YIBEISSEA. — Eeceptacle capitato-pileate, margin at first adnate, soon free. 



Tribe IV. CUPULATI. 



Eeceptacle patellaeform, margined. Hymenium superior, more or less closed when young, and concave. 



In Peziza, the reproductive bodies which fly off in clouds of dust on the plant being 

 touched, are sporidia which were regularly packed in each case. It is unneccessary to en- 

 cumber the present sketch, with the sub-series and species of the Cuptilati, many of which 

 are minute, we refer the student to the English Flora for full particulars, inserting only 

 1. PEZIZA. — Receptacle more or less concave (cup-shaped), soon expanded, the disc naked, 



Tribe V. TREMELLINI. 



Receptacle various in form, of a more or less gelatinous substance ; spores at length biu'sting forth. For 

 species vide 'English Flora'. 



Tribe VI. SCLEROTIACEI.

With these latter orders and tribes, the present work has little to do, since they are 

 essentially subjects for investigation, in which the naked eye fails. Those who can afford to
