• Obs. The following fungi seem to be different.

• torulosa, with a convex, slightly glabrous, smooth, whitish pileus, with a torulose swollen/knotty, undulate margin; with very short sinuses, some of which are pore-like.
  Daedalea gibbosa. Trattinn. Fung. austr. Fasc. I. p. 150. t. 15. f. 31. (excluding the synonym).

It grows around Vienna, Austria, on still-living oaks, in summer.
The pileus extends in a vertical direction, with a very gibbous surface, lacking zones, with a very obtuse margin; 3–4 inches wide. The sinuses are white, straight, and narrower. Tratt.

• sinuosa, large, very thick, sub-imbricated, with a convex, uneven, tuberculose, tomentose, broadly zoned pileus; with simple, equal sinuses of varying direction.
  Boletus sinuosus. Sowerb. t. 194.

Gathered in England, in autumn, at the root of an old poplar. According to the illustration, it is a span wide and 3 inches high; at first pale, but eventually nearly blackening, and it is covered with a pitch-like gluten, especially at the margin; internally it is white with a fibrous-villous texture. Sowerb.

18. polyzona, large, imbricated, depressed, with a thin, opaque, tomentose, pale-grayish pileus, banded with many zones; with equal, very short, rather thin, wood-pale sinuses.
Gathered in France (Brittany). More than a span wide, soft to the touch. Seen from above...
