While both this species and C. dumetorum var. laricina share a papillate basidiospore germ pore, the latter is separated by its negative ammonia reaction, slightly rugose, initially pruinose pileus, and caulocystidia that consist of a mixture of cylindrical to clavate elements (Hausknecht 1995). It differs from C. abjecta, which has slightly larger basidiospores (up to 8.5 μm long), mixed lecythiform and non-lecythiform caulocystidia, and lacks pileocystidia (Hausknecht 2003). It differs from C. spinulosa in having non-lecythiform caulocystidia and occurring on rotten hardwood in tropical rainforests (Hausknecht and Krisai-Greilhuber 1998). This species is distinguished from C. stictospora by the latter possessing mixed lecythiform and non-lecythiform caulocystidia and lacking pileocystidia (Singer 1989). It differs from C. missionum, which has slightly larger, somewhat angular basidiospores and a type locality in Argentina (Singer and Digilio 1951). The species is separated from C. horakii, which is characterized by its caulocystidia that comprise approximately 25 % lecythiform and 75 % non-lecythiform elements, and its growth on wood of N. fusca in New Zealand (Watling and Taylor 1987). It is distinguished from C. mandshurica by the latter’s obtusely conical to conical-convex pileus and larger basidiospores (Malysheva 2012 a). This species differs from C. incerta, which has lecythiform cystidia (including cheilocystidia, caulocystidia, and pileocystidia) with a larger capitulum diameter (Malysheva 2017). Phylogenetically, this species is closely related to C. subfusispora, with the two forming a sister group relationship. However, they are distinguished by the latter having slightly larger, subfusiform basidiospores.</p></div>	https://treatment.plazi.org/id/691DD6AD99055E8D9811550B6665CD44	Public Domain	No known copyright restrictions apply.

Although this species and C. dumetorum var. haeoleiospora both share a glabrous pileus, the latter differs in its dark brown to nearly black-brown pileus color, pronounced striations, and non-lentiform basidiospores (Hausknecht 1995). Compared with C. abjecta, which has slightly larger basidiospores (up to 8.5 μm long), lecythiform and non-lecythiform caulocystidia, and lacks pileocystidia, the present species is distinct (Hausknecht 2003). It differs from C. spinulosa, which has an umbonate pileus, non-lecythiform caulocystidia, and occurs on rotten hardwood in tropical rainforests (Hausknecht and Krisai-Greilhuber 1998). Separation from C. stictospora is based on the latter possessing mixed lecythiform and non-lecythiform caulocystidia, lacking pileocystidia, and inhabiting decomposing leaves in tropical forests (Singer 1989). This species is distinguishable from C. missionum, which has slightly larger, somewhat angular basidiospores with a distinct, papillate germ pore and a type locality in Argentina (Singer and Digilio 1951). It is distinguished from C. horakii by the latter having mixed lecythiform and non-lecythiform caulocystidia and occurring on wood of Nothofagus fusca (Hook. f.) Oerst. in New Zealand (Watling and Taylor 1987). This species differs from C. mandshurica, which has an obtusely conical to conical-convex, hairy pileus, larger basidiospores, and a pileipellis with scattered hairs (Malysheva 2012 a). It also differs from C. incerta, characterized by a subumbonate, hairy, and distinctly striate pileus and cystidia with a larger capitulum diameter (Malysheva 2017). Phylogenetically, this species forms an independent clade sister to the clade containing C. arenicola and C. subfusispora . The latter two species are distinguished by their distinctly pubescent pileus.</p></div>	https://treatment.plazi.org/id/CED0B1D257305E8BA226B62B07128477	Public Domain	No known copyright restrictions apply.
