92 Polyporoid Fungi. [ZOE 
included as sub-genera Fistulina, Polyporus and Poria). Fries in 
1821' recognized five genera: Merulius, Dedalea, Polyporus, Boletus 
and Fistulina; in 1836° he added Trametes, Cyclomyces, Hexa- 
gonia, Favolusand Porothelium, and retains essentially the same ar- 
rangement in his Opus Maximus in 1874°. Berkley separated 
_Strobilomyces from Boletus in 1860‘, and Kalchbrenner set apart 
Boletinus in 1873°; in this he has been followed by Peck,® who has 
made a special study of the American forms. Later writers have 
been more profuse in establishing genera. Peck’ established My- 
riadaporus, which is based on an apparently monstrous growth; 
Karsten in 1881° from a study of the flora of Finland alone estab- 
lished eighteen new genera; Schrceter in 1888°, while adopting only 
a few of Karsten’s new genera, added three of his own from the 
flora of Silesia; Ellis and Everhart” have separated Mucronoporus 
based on the exceedingly slender character of pubescence of the 
interior of the pores! following a doubtful analogy to Hymeno- 
cheete, and last of all, M. C. Cooke has separated Sclerodepsis" from 
Trametes, a genus which already lacked any marked characters to 
separate it from Polyporus. ;

_ separates Merulius lacrymans under Serpula Pers. (1801, as sub-genus), revives 
_ Suillus Mich. (1729), and further includes all of Lenzites among the Pylyporei.
