This species may be confused with Tinctoporellus epimiltinus (Berk. & Br.) Ryvarden, which has similar colour (bluish white and light beige), pores (angular to round, 7–9 per mm), and dimitic hyphal system. However, the ellipsoid to subglobose basidiospores [4–5 (5.5) 9 2.5–3 µm], absence of dendrohyphidia and cystidioles separate it from G. brasiliensis. Besides, G. brasiliensis don’t group in the Tinctoporellus clade, but form a monophyletic lineage with strong support within the Grammothele clade (Hyde et al. 2019).
