The phylogenetic analysis of the Trapeliaceae by Resl & al. (2015) rejected the monophyly of the genus Rimularia Nyl. as traditionally circumscribed. Rimularia s.str. (around the type species R. limborina) forms a basal group with Trapeliaceae, while 11 species were placed in the genus Lambiella Hertel, originally described as monotypic for L. psephota, which differs in molecular characters, in the presence of depsidones, and perhaps in the apical apparatus of the asci, being presently placed in the Xylographaceae. The species were monographed by Hertel & Rambold (1990). British species were treated by Fryday (1999) and Cannon & al. (2021). A useful key was published by Wirth & al. (2013).
The present key includes all species of the two genera known to occur in Italy (Nimis 2016), plus a few species reported from neighbouring countries and to be looked for in Italy, for a total of 7 species.
