Bryoclavula phycophila

Bryoclavula phycophila is a species of fungus of uncertain familial placement in the order Cantharellales. The fungus forms a tiny, club‑shaped basidiolichen—a lichen in which the fungal partner belongs to the Basidiomycota—described in 2020 from a humid gorge in Kumamoto Prefecture, Japan. The fungus makes its living in partnership with single‑celled green algae and produces minute white fruiting bodies only a few millimetres tall that stand above fading moss cushions on shaded rock faces during late autumn and early winter. The species represents an entirely new genus, Bryoclavula, and adds another lichen‑forming lineage to the otherwise mushroom‑dominated order Cantharellales. ...read more on Wikipedia.
