'''''Calopadia editiae'''''{{#tag:ref|Originally spelled ''Calopadia editae'',<ref name="Lumbsch et al. 2011"/> but later corrected to ''editiae''.<ref name="IF: Calopadia editiae"/>|group=note}} is a species of lichen in the family Ectolechiaceae. It is found in Tanzania, with a distribution that extends to Costa Rica and the Galápagos Islands. It can be found on leaves or bark and is characterised by its pale grey to brownish grey colour, rounded apothecia and distinctive {{lichengloss|pruina}}. Described as new to science in 2011, the species was named in honour of Hungarian lichenologist Edit Farkas.

==Taxonomy== The first scientific collections of ''Calopadia editiae'' were made by Hungarian lichenologist Edit Farkas in 1989. She discovered the lichen in Tanzania, specifically in the Morogoro Region, on the south-eastern slope of Mount Kanga at an elevation between {{convert|850|and|1200|m|ft|abbr=on}}. Antonín Vězda intended to dedicate the species to her but was unable to do so before his death in 2008. José Luis Chaves and Robert Lücking used Vězda's original name and validly published the species in 2011.<ref name="Lumbsch et al. 2011"/>

==Description== ''Calopadia editiae'' is a foliicolous or corticolous lichen, meaning that it grows on leaves or bark. The thallus, or vegetative body of the lichen, is continuous or dispersed into rounded, confluent patches up to 50&nbsp;mm across and 20–40&nbsp;μm thick. Its colour ranges from pale grey to brownish grey, and the surface is smooth and lacks a cortex. The apothecia, or fruiting bodies, are rounded, 0.5–1&nbsp;mm in diameter and 250–350&nbsp;μm high, with a light brown {{lichengloss|disc}} that is initially flat but becomes convex as the apothecium matures. The disc is covered with a thick, pale yellowish to cream-coloured {{lichengloss|pruina}}, which is a powdery substance found on the surface of some lichens. The ascospores are oblong to ellipsoid, {{lichengloss|muriform}}, colourless, and measure 50–80 by 20–30&nbsp;μm.<ref name="Lumbsch et al. 2011"/>

''Calopadia editiae'' is similar in appearance to ''Calopadia perpallida'', another pantropical lichen species. However, ''Calopadia editiae'' can be distinguished by its shorter ascospores, which typically measure 50–80 by 20–30&nbsp;μm, as opposed to the longer ascospores of ''Calopadia perpallida'' that mostly exceed 100&nbsp;μm in length.<ref name="Lumbsch et al. 2011"/> ''Calopadia saxicola'' is another species with pruinose apothecia and muriform ascospores, but its asci typically contain 2 or 3 spores, and it has a whitish (rather than yellowish) pruina on its apothecia.<ref name="Gumboski 2015"/>

==Habitat and distribution== ''Calopadia editiae'' has a wide tropical distribution and has been found in collections from Tanzania, Costa Rica, and the Galápagos Islands. It grows on leaves or bark and is typically found in more or less exposed microsites at low to mid elevations.<ref name="Lumbsch et al. 2011"/>
