Article: Buchanan, P.K.; Ryvarden, L. (1988). Type studies in the Polyporaceae - 18. Species described by G.H. Cunningham. Mycotaxon 31(1): 1-38.
Notes: The colour, irregular hymenophore, trimitic hyphal system, and spore characters of this species
conform well to the genus Gloeophyllum P. Karst. Although many species in the genus have
cystidia, there are some like G. concentricum which lack them.
The protologue description is adequate except for the shape and size of spores, described by
Cunningham as elliptical, 3-3.5 x 1-1.5 µm. Spores from the type, and only collection of this fungus
in herb. PDD, measure 4.2-6 x 1.5-1.8 µm and are better described as cylindrical, straight or weakly
curved. The concentric arrangement of lamellae is a highly characteristic feature of this species.
