Pallidogramme is a genus of lichen-forming fungi in the family Graphidaceae. It has 8 species of corticolous (bark-dwelling), crustose lichens.
Taxonomy
Pallidogramme was proposed in 2008 by the lichenologists Bettina Staiger, Klaus Kalb, and Robert Lücking, as a replacement name for Leucogramma {{au|A.Massal}}. The justification for this change originated from the previously established Hemithecium subgen. Leucogramma by Staiger in 2002. There was, however, a pre-existing generic name, Leucogramma {{au|A.Massal.}}, which was based on the same species as Staiger's subgenus, Hemithecium chrysenteron. Both of these names were unusable at the genus level due to their homonymy with Leucogramma {{au|G.Mey.}} a name with unknown taxonomic affinity. As a result, a new name was deemed necessary to avoid confusion and maintain nomenclatural clarity.
Description
The defining features of genus Pallidogramme include a crust-like, bark-dwelling thallus, fully formed labia, a predominantly {{lichengloss|inspersed}} hymenium, and an {{lichengloss|exciple}} which is non-{{lichengloss|carbonized}}, displaying a spectrum of colours from pale yellowish-brown to reddish-brown, accompanied by internal striations. Moreover, it possesses {{lichengloss|ascospores}} that range in colour from pale brown to brown, and that turn reddish-brown when stained with iodine (I+).

Pallidogramme indica was proposed as a new species from India in 2009, but it was not published validly; a similar situation occurs with the proposed Pallidogramme undulatolirellata {{au|A.Dube & Makhija (2009)}}, and Pallidogramme bengalensis {{au|B.O.Sharma & Khadilkar (2011)}}.
Former Pallidogramme species:
- Pallidogramme commutabilis {{au|(Kremp.) Chitale & Makhija (2009)}} is now Platygramme commutabilis
- Pallidogramme montiscalvi {{au|(A.W.Archer) A.W.Archer (2009)}} is now Phaeographina montiscalvi
- Pallidogramme nilgiriensis {{au|(Adaw. & Makhija) Kr.P.Singh & Swarnal. (2008)}} is now Graphis nilgiriensis.
