CHAPTER VI 



SPORE-DISCHARGE IN THE HYDNEAE, TREMELLINEAE, 

 CLAVARIEAE, AND EXOBASIDIEAE 



Preliminary Remarks Spore-discharge in the Hydneae Spore-discharge in the 

 Tremellineae The Basidial and Oidial Fruit-bodies of Dacryomyces deliquescens 

 Spore-discharge in the Clavarieae The Genus Calocera Spore-discharge in 

 the Exobasidieae 



Preliminary Remarks. The following are the main groups of the 

 Hymenomycetes : 



Tremellineae Hydneae 



Clavarieae Polyporeae 



Thelephoreae Agaricineae 



Exobasidieae 



The investigations upon the production and liberation of the 

 spores of Hymenomycetes so far recorded in the pages of this work 

 were made upon the Agaricineae, the Polyporeae, and the Thele- 

 phoreae. The object of this Chapter is to treat of the production 

 and liberation of spores in the remaining groups of Hymenomycetes, 

 namely, the Hydneae, the Tremellineae, the Clavarieae, and the 

 Exobasidieae. 



The relation of structure to function in the fruit-bodies of the 

 Agaricineae, although the subject of many remarks in Volume I, 

 is dealt with in this second Volume in various places, particularly 

 in the descriptions of the Sub-types of organisation in the Agari- 

 cineae ; and some special observations on the mechanical signifi- 

 cance of the stipe, the pileus-flesh, and the gills of Psalliota 

 campestris, which are of wide application, will be found in the 

 Chapter devoted to that species. For some further observations 

 in this Volume upon spore-discharge in the Polyporeae and
