DouBTFUL SPECIES 
Paxillus Curtisit Berk.; Berk. & Curt. Ann. Mag. Nat. Hist. ID. 12:423. 1853. De- 
scribed from specimens collected on pine logs in northern Georgia. ‘This species, which was 
overlooked by Saccardo, is apparently not distinct from T. corrugata, judging from the de- 
scription. 
Paxillus reniformis Berk. & Rav.; Berk. & Curt. Ann. Mag. Nat. Hist. II. 12 : 424. 
1853. Described from specimens collected on oak rails at Sulphur Springs, North Carolina. 
The brief description would suggest T. lamellosa, although this species usually occurs on pine 
rather than oak. The lamellae are said to be at first whitish and at length brownish-fer- 
ruginous on account of the spores.
