Small broken quills having a grayish fissured cork, more or less covered with white lichen patches, but often partially or wholly removed, showing the dull brown inner bark; inner surface smooth; bast fibers few; fracture short, resinous; odor feeble, stronger when rubbed; when ignited, it emits a strongly aromatic odor, somewhat resembling musk, but weaker and more agreeable; taste warm, aromatic, very bitter.
