468. Poria candidissima. A thin, soft, white species with large pores 

 and loosely adherent subiculum. I think I have collected it. 



469. Poria interna. No specimen found. 

 472. Poria Ulacina. No specimen found. 



POROTHELIUM. 



It is my conviction that there is but one species, Porothelium fimbri- 

 atum, in Europe and United States, hence all three of Schweinitz' species 

 (Porothelium subtile, fimbriatum and Peslsoides) for me fall into one 

 (P. fimbriatum). There is no specimen of his "new species" Porothelium 

 pezizoides" in his herbarium, but I have seen authentic material in Europe 

 and consider it only a young condition of P. fimbriatum. 



DAEDALEA. 



Under this head Schweinitz classed what are now called Daedalea and 

 Lenzites. 



476. Daedalea biennis. Our American plant takes usually an abortive 

 form called Polyporus distortus. That it is only a geographical form of 

 Polyporus rufescens, or Daedalea biennis a synonym, there is no doubt in 

 my mind. There is no specimen in Schweinitz' collection. 



477. Daedalea quercina. Correct without question, although there is 

 no specimen in the collection. 



478. Dadedalea betulina. Correct as Lenzites. 



479. Daedalea saepiaria. Correct as Lenzites. 



480. Daedalea abietina and 



481. Daedalea trabea and 



482. Daedalea confragosa and 



483. Daedalea Pini are all four misdeterminations for Lenzites 

 saepiaria. 



484. Daedalea unicolor. Correct. 



485. Daedalea variegata, a form at best, of Lenzites betulina. 



486. Daedalea gibbosa. Specimen so eaten it can not be referred, 

 excepting that it has no resemblance to Daedalea gibbosa of Europe, which 

 is not known to occur in the United States. 



487. Daedalea albida and 



488. Daedalea discolor and 



489. Daedalea rubescens are all three Daedalea confragosa. 



490. Daedalea angustata and 



492. Daedalea zonata are the thin, zonate, Lenzitoid, Southern form of 

 Daedalea confragosa, better known as Lenzites corrugata. 



491. Daedalea aurea. This has a soft, pubescent pileus, but otherwise 

 appears to be Lenzites saepiaria as referred by Berkeley. I think it is an 

 unusual form. 



493. Daedalea subtomentosa. No specimen. Probably same as recently 

 called Daedalea juniperinus. 



494. Daedalea Meruloidcs. Probably Paxillus olivaceus (cfr. No. 300). 



MERULIUS. 



495. Merulius tremellosus. Correct. Why Schweinitz should have re- 

 ferred the very similar species Merulius incamatus (cfr. No. 290) to a
