Etymology: Omphalia growing on wood (lignum)
Diagnosis: Pileus clitocyboid or omphalioid, usually distinctly infundibuliform with deeply depressed centre, glabrous or slightly pruinose to minutely scaly at centre, ochraceous, umbrinous, clay coloured, orange, or lightly red-brown; lamellae deeply decurrent, cream coloured or yellowish; stipe cylindrical or broadened towards base, pruinose or minutely pubescent, yellowish at apex and darker at base, ochraceous, yellowish or brightly orange; spore print white; basidiospores thin-walled, amyloid; cheilocystidia present; pleurocystidia absent; pileipellis a cutis made up of radially arranged hyaline hyphae; pileo- and caulocystidia present; clamp connections present.
Ecology: On trunks or decayed wood of coniferous, more rarely deciduous trees.

Figure 1. Phylogenetic placement of the studied fungi based on the concatenated nrITS and nrLSU sequences. The topology represents 50 % majority rule consensus tree from analysis in MrBayes. Bayesian PP ≥ 0.70 followed by Maximum likelihood BS ≥ 60 supports are indicated. Maximum likelihood tree was computed by IQ-TREE software. The Myxomphalia maura and Gamundia leucophylla were used as outgroups. Strongly supported branches (≤ 1.00/95) are doubled in width and the sequenced obtained are printed in bold.
