Odontotremataceae is polyphyletic and constitutes two distantly related clades, the true Odontotremataceae and a segregate group within Stictidaceae including Odontotrema cassiopes, O. diffindens, lichenicolous Odontotrema species and Bryodiscus arctoalpinus. Sphaeropezia here is accepted as the name for this latter group. An updated phylogeny of the Stictidaceae based on mtSSU, nuLSU and the protein coding gene RPB2 is presented together with a taxonomic revision of Swedish taxa of Odontotrema and Sphaeropezia. Bryodiscus and Lethariicola are synonymized under Sphaeropezia, and three new Sphaeropezia species are described: the lignicolous S. capreae, the fungicolous S. lyckselensis and the lichenicolous S. mycoblasti. The new species are distinguished from other species by molecular and morphological characters, and substrate preferences. The new combinations Sphaeropezia arctoalpina, S. cassiopes, S. grimmiae, S. hepaticarum, S. melaneliae, S. ochrolechiae and S. thamnoliae are proposed. The morphology of these species was studied in detail. We further propose to combine the remaining lichenicolous Odontotrema species, exept O. stereocaulicola, in Sphaeropezia based on their close relationship to the studied lichenicolous taxa. These additional new combinations include Sphaeropezia bryoriae, S. cucularis, S. figulina, S. intermedia, S. japewiae, S. lecanorae, S. navarinoi, S. pertusariae, S. rhizocarpicola, S. santessonii, and S. sipei. A lectotype is designated for the name Odontotrema diffindens Nyl.
