Aureoboletus singeri resembles Aureoboletus viscosus and A. longicollis in having velar remnants at pileus margin, viscid pileus surface, and similar colors ( Halling & Ortiz-Santana 2009). However, Halling et al. (2015) proved that A. singeri still belongs to Boletellus and is separated from members of Aureoboletus . However, the assignment of this species to Aureoboletus in the phylogenetic tree of Kuo & Ortiz-Santana (2020) and Ayala-Vásquez et al. (2023) seems quite plausible.

Aureoboletus elvirae Ayala-Vásquez, García-Jiménez & de la Fuente, based on a single specimen, is presently keyed out. It should also be pointed out that according to MycoBank the name status of this species is invalid Art. F.5.1 (Shenzhen)

Aureoboletus abruptibulbus (Roody, Both & B. Ortiz) G. Wu & Zhu L. Yang is undoubtedly to be settled by molecular genetic comparison on the edge of the genus Aureoboletus and probably not to be regarded as a typical representative of this genus.

Aureoboletus shichianus (Teng & L. Ling) G. Wu & Zhu L. Yang , similarly to the previous species, is completely isolated not only macroscopically (pores, habitus) but also microscopically (spore ornamentation).
