Obs. In the cited table of Bulliard, Fig. G also appears to be a species of Daedalea. Fig. P is Daedalea or Polyporus. Fig. I, L, and N? is B. versicolor Linn., and Fig. H is a variety of the same species?

It does not truly belong to the common species, and I myself have never found this fungus on alder trunks, but it seems to prefer linden trees, and occasionally oak; otherwise, it occurs throughout the whole world.
