Morphologically, the taxon is similar to C. khinganensis in the color of the basidiomata, but the apex in C. khinganensis is obtuse or broadly rounded. In the phylogenetic analysis, C. acuminatus was the closest relative to C. pseudoelongatus with strong support (PP 1, BS 100 %). Although the two species occupy a similar habitat, and have a subacute apex and flexuous basidiomata, in C. acuminatus the basidiomata have a brighter color and more strongly acute apex. Clavariadelphus acuminatus has pale to pale orange to apricot basidiomata, whereas C. pseudoelongatus has ecru-drab to light purple-drab basidiomata. In addition, microscopic features distinguish these species: C. acuminatus has smaller basidiospores (8–9.6 × 6–7.8 µm vs. 9.8–11.0 × 6.4–9.5 µm) and shorter basidia (75–99 × 8.5–13 µm vs. 81–113 × 8–13 µm). Thus, C. acuminatus and C. pseudoelongatus can be distinguished by the color of the basidiomata, and dimensions of the basidiospores and basidia.</p></div>	https://treatment.plazi.org/id/1291881873EB5076A1A792B3A1F77603	Public Domain	No known copyright restrictions apply.

This taxon is confusable with C. sachalinensis . With regard to morphological characters and molecular sequence data, C. miniatus is similar to C. sachalinensis . Both species were resolved in a clade phylogenetically close to the two species of Lentaria, but their basidiospores are oblong, thin-walled, and hyaline in the KOH. Clavariadelphus sachalinensis has tawny or light walnut-brown to light brown basidiomata; thus, it is confusing to distinguish it from C. miniatus based on the color of the basidiomata alone. However, microscopic characteristics differ between C. miniatus and C. sachalinensis . Specifically, C. miniatus has longer basidiospores (18.0–26.6 × 4–6 µm vs. 21–24 × 4–6 µm) and basidia (72–120 × 10–13 µm vs. 65–105 × 8–12.5 µm).</p></div>	https://treatment.plazi.org/id/4DE11A6794A950A3AE5720AD5B3C95F0	Public Domain	No known copyright restrictions apply.
