color for O. tomentosa should be pale yellow to pale brown. Miller writes that the spore print color for Inonotus tomentosus (which I suppose is an old name for Onnia) is whitish-buff, which aptly describes the color of the print I obtained from this collection. Size of spores for this collection matches the both Roody’s and Miller’s report.

Wondering about the discrpency in reported spore print color?
