BLAST searches of the ITS sequence of the I. biformis holotype indicate a close match to I. juturnae, with a sequence similarity of 90.9 % to the holotype of that species. However, I. juturnae differs from I. biformis by its warm yellow and smooth to minutely tomentose pileus (Bandini et al. 2023). Morphologically, I. biformis could be mistaken for I. beatifica, but the latter differs by having a relatively smoother pileus surface, paler lamellae at maturity, and uniformly white context in both the pileus and stipe (Bandini et al. 2021). Inocybe costinitii Bizio, Ferisin &amp; Dovana features more distant lamellae and almost neckless hymenial cystidia, contrasting with the narrowly lageniform cystidia of I. biformis (Bizio et al. 2016).</p><p>Moreover, I. biformis shares a squamulose or felty pileus texture with I. plurabellae Bandini, B. Oertel &amp; U. Eberh., I. flocculosa Sacc., and I. tigrina R. Heim. However, I. plurabellae exhibits highly variable pileus coloration and a finely roughened pileus surface (Bandini et al. 2021); I. flocculosa has a more uniform, less variable pileus color, a (sub) squamulose pileus texture, and a distinctly paler stipe at maturity (Kuyper 1986; Stangl 1989; Bandini et al. 2021); I. tigrina typically exhibits a bicolored, felty to sublanose pileus with diffracted fibers as well as consistently narrower basidiospores (Heim 1931; Ferrari 2006; Ludwig 2017; Bandini et al. 2021). Ecologically, I. biformis is uniquely adapted to high-altitude environments (over 4000 m), whereas the other species are predominantly distributed in Europe and often associate with different hosts at lower altitudes.</p></div>	https://treatment.plazi.org/id/D79C0847718F50C88325C4485A200CCD	Public Domain	No known copyright restrictions apply.
