Cantharellaceae. — This family contains the stichobasidial segre- 

 gates from the Thelephoraceae, Hydnaceae and Agaricaceae of the 

 earlier writers, and is characterized by a differentiation into stipe and 

 pileus. In the young buttons, the hyphae radiate in the upper part and 

 are much branched. As in Gyrocephalus of the Tremellales, an infundi- 

 buliform structure develops by strong epinastic growth. In Craterellus

Fig. 353. — Development of basidia of Craterellus cornucopioid.es. 1 to 5. Of Clavulina 

 cinerea. 6 to 10. (1 to 5, 10 X 1,200; 6 to 9 X 1,400; after Juel, 1916.) 



the hymenophore is smooth or slightly wrinkled, in Cantharellus it con- 

 sists of parallel folds similar to the lamellae of the Agaricales, but less well 

 developed. These differences are only quantitative and many inter- 

 grading forms are seen. 



Cytological investigation extends to only eight species: Craterellus 

 cornucopioides, C. lutescens, Cantharellus cibarius, C. cinereus, C. tubae- 

 formis, Thelephora palmata, T. anthocephala and Hydnum repandum
