Classification: Agaricales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Dikarya, Fungi.
Spore print white. Basidiomes small-, medium-sized, mycenoid, pleurotoid, or clitocyboid. Hymenophore lamellate or poroid. Pileus conic, campanulate, plane, or conchate; surface dry or viscid; smooth, rarely fibrillose or pruinose; margin often striate. Stipe equal, central, or lateral; hollow; surface dry or viscid, smooth, fibrillose, or pruinose; base smooth or with mycelium. Basidiospores hyaline, smooth, thin-walled, amyloid or inamyloid. Cheilocystidia present or absent, shape various, globose, ellipsoid, pyriform, fusiform, cylindrical; hyaline or pigmented; pleurocystidia present or absent. Hyphal system usually monomitic, rarely sarcodimitic. Pileipellis ranging from a cutis to a trichoderm to a hymeniderm, often with diverticulate hyphae. Clamp connections present or absent. Some species are bioluminescent. Saprotrophic (terricolous, foliicolous, lignicolous), sometimes symbiotic with orchids.
Family included: Mycenaceae Overeem 1926
Notes: In the previous study, Mycenaceae represented by a single species, Mycena luteopallens (Peck) Peck, was shown to be sister to the rest of Marasmiineae with a bootstrap value of 59, and it is accepted as a member of Marasmiineae (Dentinger et al. 2016). In the phylogenomic tree of Wang et al. (2023), Mycenaceae representing by three species is sister to the clade comprising Marasmiineae and Schizophyllineae. It is a distinct clade which cannot been classified in any suborders thus remained as Mycenaceae clade in Agaricales (Wang et al. 2023). In this study, with a broader sampling in taxa and genes, [(27 genes from one species in Dentinger et al. (2016); 555 genes from three species in Wang et al. (2023); 1286 genes from eight species in this study)], the Mycenaceae clade is found to be sister to Schizophyllineae with a full bootstrap value. Additionally, molecular dating analysis indicates its divergence time (156 Myr) is relatively equal to other suborders in Agaricales (152–182 Myr). Based on the phylogenomic relationships and divergence time, we propose the suborder Mycenineae to accommodate Mycenaceae in Agaricales.
Type genus: Mycena (Pers.) Roussel 1806.
