Notes: Lichenoconium species are distributed worldwide as lichenicolous taxa on a variety of lichen hosts (Lawrey et al. 2011; Hyde et al. 2013; Wijayawardene et al. 2017a; Diederich et al. 2018). Many are host-specific, while others occur on disparate genera (Lawrey et al. 2011). The asexual morph is characterized by coelomycetous, immersed to sessile, dark brown pycnidia, an undifferentiated pycnidial ostiole, simple conidia, globose to ellipsoid, basally often truncate, thick-walled, brown and commonly verrucose and conidiogenous cells that are hyaline or poorly pigmented, holoblastic, elongate and annellidic (Lawrey et al. 2011). The sexual morph has not been recorded.
