34 THE JOURNAL OF BOTANY 
and Prantl Pflanzenfamulien, the Bulletins de la Société Mycologique 
de France, the splendid plates of Boudier’s Icones Mycologice, 
Costantin and Dufour’s Nowvelle Flore des Champignons, and the 
writings of Quélet and Patouillard, who all recognise that the 
splitting up of this enormous genus was due to the illustrious 
Fries himself. The British Mycological Society has also taken up 
the same position, and we regret that the author has not followed 
Rule V. of Saccardo’s De diagnostica et nomenclatura mycologica 
admonita quedam, which was adopted by the British Mycological 
Society at their Whitby meeting on the 14th September, 1904; 
this really initiates no new departure, but is only a reaffirm- 
ation of an existing and well recognised principle. The rule runs 
as follows :—* When a specific name is transferred to another 
genus the original author is cited in parenthesis while the author 
of the new combination is also to be cited,” and we maintain that 
the raising of a subgenus to full generic rank a subsequent 
author does not entitle that author to treat it as a transference 
to another genus, but merely proves the soundness of the grounds 
upon which such a separation had been tentatively put forward 
71 ; 
to non-vascular plants ; and all mycologists will rejoice that this is 
so if their application should produce such an absurd array of 
authorities for species and genera. Quélet is quoted as the 
authority for the name of the genera Clitocybe and Omphalia, 
Clitocybe, and that his genus 
seed assigned to Omphalia 
name of the original creator of a g
