Remarks (public):The phylogenetic placement of C. odorata is depicted in the phylogram generated from the ML analysis of the ITS dataset. The analysis recovered a monophyletic Crinipellis clade with full ML (100 % BS) bootstrap support. Within this clade, four distinct clades (Clade A, Clade B, Clade C and Clade D) were recognised which is in agreement with the phylogenetic results of Antonín et al. (2014). Of these four clades, C. odorata was nested with members of clade D with a moderate ML (53 % BS) bootstrap support. Clade D consists of C. floccosa, C. furcata, C, odorata, C. procera and C. zonata, where C. floccosa, C. furcata, C, odorata and C. zonata were clustered together. This cluster of four species receives significant ML (94 % BS) bootstrap support. Within this cluster, C. odorata formed a lineage distinct from the remaining species with a significant ML (80 % BS) bootstrap support. A conical or applanate pileus, simple cheilocystidia and the absence of rhizomorphs are the morphological markers of clade D (Antonín et al. 2014).

Description:Basidiomata small to medium-sized, marasmioid, often in dense tufts. Pileus 6–31 mm diam, truncately conical or conico-convex with a small central depression when very young, becoming campanulate to broadly campanulate, still with a small central depression; surface dark brown (8F4, 8F5/OAC635) or reddish brown (8F7/OAC636) at the centre and on the squamules and brownish orange (6C5/OAC652) or light brown (6D5/OAC659) elsewhere, not hygrophanous, not striate, appressed- to slightly recurved-squamulose all over; margin initially incurved, becoming decurved to almost reflexed with age, finely appendiculate, crenate or somewhat wavy. Lamellae adnexed, crowded, yellowish white (4A2/OAC815) when very young, becoming greyish yellow (4B4/OAC806), up to 2 mm wide, with lamellulae of 3 lengths; edge crenate, concolorous with the sides. Stipe 39–120 × 2–4 mm, central, terete, or slightly compressed, tapering towards the base, hollow, slightly flexuous towards the base, insititious; surface concolorous with the pileus, appressed- to slightly recurved-squamulose all over, densely so towards the apex; base deeply rooted. Rhizomorphs absent. Context up to 2 mm thick, yellowish brown. Odour strong, unpleasant. Taste not distinctive. Basidiospores 5–8 × 5–7 (6.5 ± 0.77 × 5.9 ± 0.61) µm, Q = 0.86–1.3, Qm = 1.11, subglobose to almost globose, smooth, thin-walled, inamyloid. Basidia 23–33 × 6–9 µm, sparse clavate, hyaline, thin-walled, 4-spored; sterigmata up to 4 µm long. Basidioles 28–48 × 6–12 µm, abundant, fusoid or clavate, thin-walled, hyaline. Lamella edge sterile with copious cheilocystidia. Cheilocystidia 22–65 × 7–19 µm, versiform: oblong, clavate, cylindrical, cylindrical with a median constriction, flexuous, nodulose-diverticulate, sometimes capitate, thin- to slightly thick-walled, hyaline or pale yellow. Pleurocystidia absent. Lamellar trama subregular; hyphae 3–12 µm wide, thin-walled, hyaline or pale yellow, inamyloid. Pileus trama subregular to interwoven; hyphae 6–15 µm wide, thick-walled (up to 2 µm thick), with a pale yellow wall pigment, dextrinoid. Pileipellis composed of tufts of fasciculate hairs arising from a hypotrichium; hypotrichial hyphae 8–18 µm wide, thick-walled (up to 1.5 µm thick), with pale yellow wall and dense, spiral encrusting pigments; pileal hairs 500–1200 × 5–7.5 µm or more, unbranched, cylindrical or sinuouso-cylindrical with an obtuse apex, thick-walled (up to 2 µm thick), with a yellowish brown wall pigment, dextrinoid, yellowish brown in KOH. Stipitipellis composed of clusters of hairs arising from a hypotrichium with flairing-out cystidioid terminal cells; hypotrichial hyphae 3–7 µm wide, thick-walled (up to 1 µm thick), with pale yellow wall and minutely, encrusting pigments; stipitipellis hairs 47.5–452.5 × 7.5–12.5 µm, sinuouso-cylindrical, thick-walled (up to 3 µm thick), with a pale brown or yellowish brown wall pigment, dextrinoid, pale yellowish brown in KOH; terminal cells cystidioid 32–95 × 10–16 µm, clavate, cylindrical-clavate or irregular in outline, dextrinoid, thick-walled (up to 2 µm thick), with a pale yellowish brown wall pigment. Caulocystidia absent. Clamp connections observed on all hyphae except at the base of basidia.
