Based on the phylogenies of the D1/D2 regions of the LSU sequences obtained using maximum likelihood analysis, Sebacina allantoidea strongly deviates from all other sebacinalean taxa (Oberwinkler et al. 2014). Therefore, a new genus Paulisebacina (Sebacinaceae, Sebacinales, Basidiomycota) was proposed by Oberwinkler et al. (2014) to accommodate S. allantoidea (type species). Sebacina allantoidea, a species with inconspicuous basidiocarps that produce few thin-walled and hyaline substrate hyphae without clamps, and lacks a subhymenium, was isolated as saprobic from the wood and bark of stem bases of ornamental Spiraea sp., this species normally developing in the cold season (Kirschner & Oberwinkler 2002, Oberwinkler et al. 2014). No other species have been introduced to this genus, which remains monotypic.
Type species: Paulisebacina allantoidea (R. Kirschner & Oberw.) Oberw., Garnica K. Riess & R. Kirschner
Other accepted species: This genus is monotypic.
