Hymenogaster albo-ovoideus is easily confused with H. niveus Vittad. by their similar morphology with snow white basidiomes (Dodge and Zeller 1934; Stielow et al. 2011). However, H. niveus differs from H. albo-ovoideus by its basidiomes turning red upon bruising or handling and diverse basidiospore ornamentations (Stielow et al. 2011; Dodge and Zeller 1934). Hymenogaster albo-ovoideus was phylogenetically sister to H. pseudoniveus L. Fan &amp; Ting Li, a new species found in Hebei, Shanxi and Shaanxi Provinces, Northern China. However, H. pseudoniveus differs from H. albo-ovoideus by its ellipsoid to broadly ellipsoid basidiospores (Li et al. 2024 b).</p><p>Two ITS sequences (LC 711550, AY 310842) extracted from ectomycorrhizal root tips downloaded from GenBank matched H. albo-ovoideus in our analysis, one of which was from Japan (LC 711550), and another from USA (AY 310842). That could imply that H. albo-ovoideus may occur in both Japan and the USA. Moreover, BLASTn revealed that H. albo-ovoideus shares less than 95.75 % ITS similarity with sequences from the NCBI database.</p></div>	https://treatment.plazi.org/id/969A863714AE54849EFB2903769A9208	Public Domain	No known copyright restrictions apply.
