The species E. shenghuae can be easily distinguished from E. murina by an uncracked smooth to grandinioid orange-white to pale orange hymenophore with irregular and scattered granules, longer basidia (23–38 × 4.5–7 µm vs. 15–24 × 4–6 µm), and larger oblong ellipsoid basidiospores with an apiculus (6–6.5 × 3–3.5 µm vs. 4–5.5 × 2.5–3 µm; Li et al. 2022).</p></div>	https://treatment.plazi.org/id/66EB241B65595628B2FECBB90D960817	Public Domain	No known copyright restrictions apply.

Hymenial surface white, whitish buff to “ Amber, ” thinning out indeterminately, sometimes pruinose under the lens. Hyphal system monomitic; generative hyphae simple-septate, smooth, thin- to slightly thick-walled. Cystidia absent or present, rarely fusiform cystidia present in the hymenium. Basidia cylindrical to clavate with a stalk-like base, sometimes slightly constricted without a basal clamp, producing four sterigmata. Basidiospores broadly ellipsoid, smooth, thin-walled (Chen et al. 2021, 2022; Li et al. 2022).</p><p>Notes.</p><p>The genus Efibula was circumscribed by Wu (1990), with Efibula tropica Sheng H. Wu designated as the type species (Wu 1990). Efibula was traditionally classified in the family Phanerochaetaceae (Kirk et al. 2008) . With revisions to the family-level classification of the order Polyporales, phylogenetic analyses support the placement of Efibula in the family Irpicaceae (Justo et al. 2017; Chen et al. 2021; Osman and El-Nuby 2023; Wang et al. 2023). Although Efibula and Phanericium are not easy to separate morphologically, they are genetically distinct. In general, Efibula species have a more compact texture with a dense subiculum that is not always clearly distinguished from the subhymenium (Larsson et al. 2025). In this study, three new species ( E. murina, E. yaoshanensis, and E. zhaotongensis) are introduced based on morphological characters and multigene phylogenetic evidence. Comparative characteristics of Efibula species are presented in Table 2 to establish taxonomic differentiation for the newly proposed species.</p></div>	https://treatment.plazi.org/id/F3E78D6F7B2550C497F7C4750E3C5AF9	Public Domain	No known copyright restrictions apply.

(2021) provided comprehensive morphological and phylogenetic analyses of hydnoid species in the family Steccherinaceae, identifying four genera, Cabalodontia Piatek, Etheirodon, Metuloidea, and Steccherinum . In the present study, the novel genus Odentinium is proposed based on morphological characteristics and phylogenetic analyses inferred from the combined ITS + nLSU + mtSSU + rpb 2 + tef 1 - α sequence dataset (Fig. 2). Six wood-inhabiting fungal specimens from Southwest China formed a distinct clade with strong support within Steccherinaceae in the phylogenetic analyses. Morphologically, these six specimens have soft corky to leathery basidiomata with odontioid hymenial surfaces that are cream to pale yellow and cover the aculei, a monomitic hyphal system, thin-walled generative hyphae with clamp connections, numerous thick-walled cylindrical cystidia, thin-walled clavate basidia with four sterigmata and a basal clamp connection, and thin-walled ellipsoid to globose basidiospores. These characteristics distinguish Odentinium from known genera in Steccherinaceae . Therefore, Odentinium is proposed as a new genus based on morphological characteristics and phylogenetic analyses.</p></div>	https://treatment.plazi.org/id/54E650FAF6B4581D9CB4D4C06CBA3681	Public Domain	No known copyright restrictions apply.
