302. Schizophyllum commune. Specimen correct. 



Boletus, Nos. 303 to 319, but one specimen is preserved, viz., No. 315 

 Boletus floccopus. This is now known as Strobilomyces strobilaceus, and 

 it is doubtful if Strobilomyces floccopus is different, not in the sense of 

 Schweinitz at least. 



POLYPORUS 



Section subcarnosi 



Now known as Section Ovinus. There are no specimens preserved now 

 in this section. From our knowledge of the species that occur and Schwei- 

 nitz' record, we feel able to interpret his record. 



320. Polyporus subsquamosus. No specimen preserved. The plant that 

 Peck has named Polyporus griseus, and Fries poorly figured as Polyporus 

 subsquamosus, but very doubtful as to "Linnaeus." Compare my pamphlet 

 on section Ovinus, p. 78. 



321. Polyporus ovinus. No specimen preserved. The records of Poly- 

 porus ovinus in this country are so doubtful (cfr. Ovinus, p. 76) that it is 

 doubly unfortunate that Schweinitz did not preserve his specimen. From 

 the name Schweinitz first applied to the plant (albidus), it is probable 

 that he did find Polyporus ovinus. It is certainly very rare, if it occurs 

 in the United States, though it is frequent in Sweden. It is the only 

 fleshy, mesopodial species of Europe which any one would be liable co 

 designate as "albidus." 



322. Polyporus melanopus. The specimen is devoid of stem, but is 

 a small plant of what is now known as Polyporus picipes. It is not 

 melanopus, which is a closely related plant of Europe. 



323. Polyporus fuligineus (in error evidently as fuliginosus). It has 

 large pores, and is not fuligineus as illustrated in Europe, which has 

 minute pores, although fuligineus is not a species now known in Europe, 

 being based on an old figure (cfr. Stipitate Polyporoids, p. 168). Schwei- 

 nitz records Polyporus fuliginosus as being "frequent" in woods, but his 

 specimen is not a species "frequent" nowadays. It is a small specimen 

 of what Peck has referred to Polyporus pallidus, and which I consider as 

 a scaleless form of Polyporus squamosus (cfr. Ovinus, p. 85), a rather 

 rare plant. Sumstine recently discovered that it was a new species, and 

 called it Polyporus Pennsylvanicus. Schweinitz has no record of Polyporus 

 squamosus, and undoubtedly never met it. 



324. Polyporus brumalis. No specimen preserved. As Schweinitz re- 

 cords brumalis "rare" and leptocephalus "common," what he called lepto- 

 cephalus was probably brumalis. 



325. Polyporus ciliatus. No specimen preserved. Probably the late 

 summer form of Polyporus arcularius, which is depauperate and ciliate. 

 It was called by Berkeley Favolus Curtisii, and renamed by Murrill, Poly- 

 porus arculariellus. Schweinitz records the common Polyporus arcularius 

 in h:s Fung. Car., but overlooks it in his second work. 



326. Polyporus leptocephalus. No specimen preserved. Probably 

 based on brumalis, for leptocephalus is not known in Europe now except 

 from old figures, and is certainly not "passim" in America (cfr. 324).
