Its context turns reddish-brown when bruised. Inosperma fibrifugum forms a sister species pair with I. mucidiolens (Grund &amp; Stuntz) Matheny &amp; Esteve-Rav. (Fig. 1). In both species, the stipe and lamellae become reddish when bruised, and the basidiospores and basidia have similar dimensions. However, I. mucidiolens has shorter stipes (30–90 mm), pileus scales that do not slough off at maturity, longer cheilocystidia (33–50 µm), larger caulocystidia (27–50 × 10–22 µm), and an odor reminiscent of fresh corn (Grund and Stuntz 1970).</p><p>Inosperma glomerisquamulosum, a newly described species in this study, is closely related to I. fibrifugum . Both species share a hemispherical to campanulate pileus and similar basidiospore shapes. However, I. glomerisquamulosum is distinguished by its smaller basidiomata (4–45 mm), lack of reddening when bruised, stipe base lacking bluish-green to indigo coloration, larger basidiospores (13.0–15.5 × 6.5–8.0 µm vs. 10.0–12.0 × 5.0–6.5 µm), and absence of caulocystidia.</p><p>Inosperma cervicolor (Pers.) Matheny &amp; Esteve-Rav. shares with I. fibrifugum a centrally scaled, conic-campanulate pileus, context and lamellae that bruise reddish-brown, and a grayish-green stipe base. However, I. cervicolor is distinguished by its smaller basidiomata (pileus 6–40 mm), larger basidiospores (10.5–14.5 × 6.5–8.0 µm vs. 10.0–12.0 × 5.0–6.5 µm), and larger cheilocystidia (35–6 × 9–15 µm).

Its pileus surface is covered with appressed, clustered, yellowish-brown scales when young. At maturity, there are erect conical scales in the center, and the outer clusters of appressed scales change from appressed-fibrillose to fibrillose. Caulocystidia are absent in this species, and its odor is indistinct. Inosperma glomerisquamulosum is phylogenetically closely related to I. turietoense Pancorbo &amp; Esteve-Rav. (Fig. 1). Both species possess hemispherical pileus with appressed scales on their surfaces and have smooth, ellipsoid basidiospores. Their basidia and cheilocystidia are also comparable in shape and size. However, I. turietoense has smaller basidiomata (pileus 20–30 mm), a context that turns reddish upon bruising, and smaller basidiospores (10.4–13.4 × 6.4–7.3 μm vs 13.0–15.5 × 6.5–8.0 µm) (Esteve-Raventós et al. 2024). This species also possesses caulocystidia and has a distinct odor, ranging from earthy to moldy and sometimes blended with aromatic components (Esteve-Raventós et al. 2024).</p><p>Inosperma glomerisquamulosum is morphologically similar to I. gracilentum E. Larss. &amp; Esteve-Rav., sharing a conical-campanulate pileus and a stipe apex covered with minute scales. However, I. gracilentum exhibits smaller basidiomata (pileus 5–25 mm), reddening of the upper stipe context with a bluish-green base, and smaller basidiospores (10.8–13.7 × 6.0–7.4 μm vs. 13.0–15.5 × 6.5–8.0 µm), as well as the presence of caulocystidia (20–42 × 9–16 μm) and a distinct odor of pelargonium or fish, distinguishing it from I. glomerisquamulosum (Esteve-Raventós et al. 2024).</p><p>Both Inosperma glomerisquamulosum and I. neohirsutum Esteve-Rav. et al. possess a conical-campanulate pileus with erect conical scales at the center at maturity. Their basidia and cheilocystidia are of the same size and shape. However, I. neohirsutum differs in having smaller basidiomata (pileus 15–25 mm). The upper part of the stipe turns slightly reddish when bruised. It has a bluish green stipe base, smaller basidiospores (9.0–10.9 × 5.0–6.1 μm vs. 13.0–15.5 × 6.5–8.0 µm), caulocystidia and a variable odor. This odor can be faint, aromatic, or fruity-acidic at times, and at other times, it may have a scent of pelargonium or fish (Esteve-Raventós et al. 2024).</p></div>	https://treatment.plazi.org/id/56B36D11C85D5AA291262A01DC50EB4F	Public Domain	No known copyright restrictions apply.
