(Lundae) 1: 498 (1821) Typhula muscicola (Pers.)

Eocronartium muscicola is a species of fungus belonging to the order Platygloeales.

It is currently the only species in the monotypic genus Eocronartium.

[1][2] In the UK its recommended English name is moss rust.

[3] The species forms clavarioid basidiocarps (fruit bodies) on mosses, on which it is parasitic.

[4] At least 21 moss species, all in the subclass Bryidae, are recorded as hosts for Eocronartium muscicola.

[5] The fungus parasitizes its host through its gametophytic transfer cells.

[4] The species appears to be widespread, with most reports from Europe, North and South America.
