included as sub-genera Fistulina, Polyporus and Poria). Fries in 

 1821^ recognized five genera: Merulius, Daedalea, 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 i86o\ 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 iS8i^ from a study of the flora of Finland alone estab- 

 lished eighteen new genera; Schroeter in 1888^, while adopting only 

 a i&v<i 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- 

 chaete, 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.

 tarum, Rev. Mycol. 1881. The genera are Tylopilus, Cricunopus, Tubiporus, 

 Rostkovites and Krombholtzia, among the Boletineoe; and Polypilus, Tyromyces, 

 Polyporellus, Ganoderma (founded on Polyporus lucidns), Piptoporus (founded on 

 P. betidinus), Fomitopsis, Bjerkandera (including PP. adustiis, hirsuius, versi- 

 iolor, abietijtus, etc.), Antrodia, Hapalopilus, Pycnoporus, Caloporus.Ischnoderma, 

 and Inonotus, among the Polyporea:. 



* Kryptogamen Flora von Schlesien, Pilze, i. The genera are Ochroparus, Pha;- 

 oporus and Dcedaleopsis, the last founded on Dcedalea confragosa. Schrceter also 

 separates Mertdius lacrymans under Serpula Pers. (1801, as sub-genus), revives 

 Suillus Mich. (1729), and further includes all of Lenzites among the Pylyporei.
