Korber (Parerga, 288) describes S. microcephala, Sm. 
(E. Bot., t. 1865), as having a proper thallus. According 
to Nylander (Prod., 34), the Calicium microcephalum of 
Smith (E. Bot., t. 1865) and Borrer (Lichenographia Britan., 
130) is only a form of S. turbinata, and, therefore, = var. 
microcephala, as above. But Mudd (255) refers it to S. 
anglica, Nyl. 
Several authors regarded S. turbinata and its varieties as 
Fungi, e. g. Persoon (Tent. Disp. Fung., Suppl., p. 59) ; M. C. 
Cooke, in his ‘ Index Sowerby r , Mougeot and Nestler. 
Berkeley does so still (Brit. Fungology, 1860, p. 373); but 
Cooke wrote me, in 1866, “ It has been included with Fungi, 
but I scarcely think it should rank with them.” In a sub- 
sequent letter he says, more decidedly, “ I do not think 
Sphinctrina should be associated with Fungi.”
