Neolamya was introduced by Theissen et al. (1918) to describe the lichenicolous fungus N. peltigera, originally described as Sphaeria peltigerae by Montagne (1845), which occurs on Peltigera horizontalis. The genus is characterized by small, erumpent, globose to ovate black perithecia that radially split the host thallus, and acicular ascospores (Theissen et al. 1918). Kocourková (2009) added a second species, N. xanthoparmeliae, found on Xanthoparmelia conspersa, while the third species, N. ahtii, described by Zhurbenko et al. (2017b), occurs on Cladonia gracilis. There are three species recognized in the genus. However, due to the lack of molecular data, Neolamya remains tentatively placed in Ascomycota genera incertae sedis pending further phylogenetic analysis (Hyde et al. 2024).

Type species: Neolamya peltigerae (Mont.) Theiss. & Syd. (Theissen et al. 1918).
