Tode (1791) introduced Periconia, typified by P. lichenoides. Periconia members are currently known as hyphomycetes and are characterized by having macronematous, unbranched to branched, stiff, light to dark brown conidiophores with a spherical apex, monoblastic or polyblastic, discrete conidiogenous cells and verruculose or echinulate, pale to dark brown, unicellular which are catenate, usually sphaerical to subsphaerical conidia (Thambugala et al. 2017, Phookamsak et al. 2019, Hongsanan et al. 2020a). There are 114 accepted Periconia species in Species Fungorum (2022). In this study, we introduce two new host records of Periconia

Type species: Periconia lichenoides Tode, Fung. mecklenb. sel. (Lüneburg) 2: 2 (1791).

Other accepted species: Species Fungorum – search Periconia.
