DOUBTFUL SPECIES 
Boletus alveolarius Bosc, Ges. Nat. Freunde Berlin Mag. 5: 84. pl. 4. fiz. 1811. 
Polyporus alveolarius Fr. Syst. Myc. 1: 343. 1821. Described from specimens collected on 
trunks in South Carolina. 
Polyporus pachypus Mont. Pl. Cell. Cuba 421. 1842. Collected by Sagra on dead wood 
in Cuba. No further light has been obtained relative to this species, which Montagne him- 
self said needed investigation. 
Polyporus putidus Fr. Nov. Symb. 51. 1851. Collected on trunks in Costa Rica by 
Oersted. Type not found. 
Polyporus peltatus Fries, Nov. Symb. 52. 1851. Collected by’Oersted on dead wood 
at San José, Costa Rica. Apparently very near P. Blanchetianus, but the stipe is not black. 
Polyporus amygdalinus Berk. & Rav. Grevillea 1: 49. 1872. Described from Rave- 
nel’s collections on rotten oak logs in South Carolina in October. Ravenel’s field notes are 
as follows: ‘‘Pileus lateral, dimidiate, subimbricate, carnose, 2-4 inches wide, dingy yel- 
lowish, with irregular patches of darker color — with a strong odor of vanilla or almond. 
Hymenium white, pores sinuose and irregular, minute. Stipe obsolete.’’ The type speci- 
men is too old to be of much service, but it is certainly not P. caudicinus.
