fungus ? plus so and so. In other cases where neither of the 

 symbionts is known definitely that sort of a statement could go 

 into the parenthesis. Mycologist, Pathologist, I ? , j. 



Quotation 20 



If I were classifying lichens for systematic purposes, I should 

 keep them all together as a class as a matter of convenience. If I 

 were making a scientific classification in which I was endeavoring 

 to show actual sequences and relationships, I should distribute 

 them in their natural places near their related fungus forms. 

 Since, however, the lichens have always been studied by them- 

 selves and are likely to be for a long time, I see no advantage in 

 trying to make things " natural " in any classification, by making 

 them inconvenient. Mycologist, 2, a- (r 2 ). 



Quotation 21 



I believe it proper, whether from a scientific or a practical point 

 of view, to keep the fungi and the lichens separate in two classes, 

 the one beside the other. For me the character of the symbiosis 

 with the algae and the peculiar character of the thallus is sufficient 

 to separate the two classes. Mycologist, 1, 2, p.* 



Quotation 22 



From a purely theoretical point of view, a distribution of the 

 lichens among the various fungus orders with which they are 

 related is really a matter of course, there being satisfactory 

 examples to show that lower lichens are in a certain intermediate 

 condition so that one may in various ways fix the bridges between 

 undoubted fungus genera and the lichens related to them. Never- 

 theless, it seems to me more expedient for the present to keep the 

 lichens as distinct as possible, even for systematic consideration, 

 since their dependence upon the symbiotic algae — especially in the 

 groups that have complicated thallus structure — continually forces 



* Je crois convenable, soit au point de vue scientifique que practique de tenir 

 separes en deux classes distinctes les fungi et les Lichenes, en les placant tout a 

 fait a cote les uns des autres. Pour moi le caractere de la symbiose avec 

 les algues et d'un thalle tout a fait particulier est suffisant pour separer les deux 

 classes.
