Nomenclatural notes
According to INA, the name was supposedly published by Kunze (with a Latin description?) on the label of a specimen in an informal set of specimens distributed to various herbaria, probably in 1829, dubiously valid even if there were a description. - (10 Mar 2010) - M.D. Guiry

Suto & Ohtani (2009: 228) cite the authority as Kunze 1827, in Fries 1829. - (27 Apr 2010) - Wendy Guiry

Habitat notes
Collected on 25 species and one variety belonging to 19 genera and 15 families; frequent and heavily infected collections recorded on Magnolia grandiflora and Persea thunbergii (Suto & Ohtani 2009). - (27 Apr 2010) - Wendy Guiry

On leaves (Nelsen et al. 2011). - (24 Aug 2011) - Wendy Guiry

Host: Polyalthia longifolia (Mast tree or Cemetery tree); thalli grow subcuticularly on the upper leaf surface (Suto et al., 2014). - (10 Jul 2014) - Wendy Guiry

General environment
This is a aerophytic species.
