Genus Antrodiella Ryvarden & I. Johans.

[yes, more whitish polypores]

Many are successor species that grow on wood decayed by another fungus and may grow on the old fruitbodies of that fungus. Ryvarden and Gilbertson (1993): Remarkable is the association of a number of species in Antrodiella to dead basidiocarps of other polypores and corticoid species, or at least to wood attacked by such fungi. The reason for this connection is not known.

These small white polypores with tiny pores can be found in the Chicago Region and elsewhere if you look for them. A microscope is required for identification. I have not yet confirmed which species we have for Chicago area. Most likely we have Antrodiella semisupina.

The first list are those in North America.

  • Antrodiella Ryvarden & I. Johans., A preliminary polypore flora of East Africa: 256 (1980). Type: Polyporus semisupinus Berk. & M.A. Curtis, Grevillea 1 (4): 50 (1872).
Trametes subscutellata (Murrill 1910) is kept separate from Antrodiella semisupina according to Miettinen et al. (2006). Some synonymy on Index Fungorum does not agree with the work of Miettinen et al. (2006). Certain Antrodiella have been moved to Antella, Austeria, Metuloidea, Steccherinum, Trametopsis, and Trulla. More species will likely be transferred to other genera with further research.
