Savoronala was introduced by Ertz et al. (2013) with type species Savoronala madagascariensis based on assessments of morphology and phylogenetic analysis of combined LSU and SSU sequence data. Savoronala belongs to the family Malmideaceae (Lecanorales) and is sister to Malmidea and Lecidea but do not share noticeable morphological similarities (Lucia et al. 2017). Savoronala was reported from Madagascar on the base of a stem of Erica sp. (Ertz et al. 2013). Species of this lichenized hyphomycete genus are characterized by an adnate small pale glaucous placodioid thallus, erect stipes producing sporodochia at the apex, brown, subspherical conidia wrapped around a single chlorococcoid algal cell, and the conidia become larger and brown after maturity. Although the fungal hyphae firmly envelop the algal cells, the vegetative propagules of Savoronala develop at the stipes and are dispersed fully with the fungal conidia. Savoronala clusters in a strongly supported monophyletic group with Lecidea cyrtidia, L. floridensis, L. plebeja, and Malmidea in the family Malmideaceae (Lucia et al. 2017). 

Type speciesSavoronala madagascariensis Ertz, Eb. Fisch., Killmann, Razafin. & Sérus.

Other accepted species: This genus is monotypic.
