Remarks (public):Athelia is a well delimited genus by the ephimeral and pellicular basidiome and the hymenial structure with open branched hyphae arranged in candelabrum-like clusters. According to Larsson et al. (2004), Athelia seems to be related to Piloderma, Tylospora, Byssocorticium, Atheliopsis, and Amphinema. The athelioid clade could be related to the euagarics clade by one subclade in which Amylocorticium, Ceraceomyces tessulatus, Hypochniciellum, and Anomoporia are present. The athelioid clade includes mycorrhizal species like Piloderma, Amphinema and Tylospora. A mycorrhizal habit has not been observed in Athelia and Atheliopsis, but Oberwinkler (1970) described the parasitism by A. epiphylla, on unicellular green algae and by A. arachnoidea on lichens.

Description:Athelia Pers., Mycol. eur. (Erlanga) 1: 83, 1822.
Type species: Athelia epiphylla Pers., Mycol. eur. (Erlanga) 1: 84, 1822.
Basidiome resupinate, thin, pellicular (athelioid), easily detachable, white to whitish, hymenophore smooth. Hyphal system monomitic, hyphae with or without clamps, hyaline, thin-walled, loosely interwoven. Cystidia usually absent, some species with leptocystidia. Basidia short, more or less clavate, in clusters from the subhymenial hyphae, 2-4-sterigmata, clampled or with a simple septa. Basidiospores subglobose to ellipsoid or cylindrical, smooth, thin-walled, often glued together, IKI-.
