Verruconis was introduced by Samerpitak et al. (2014) and proposed as a neurotropic opportunistic Ochroconis gallopava. This genus can grow at a temperature difference of 35 °C–42 °C (Samerpitak et al. 2014). Members of this genus have been isolated from hot spring water, warm effluents, bark, and twig soil as saprobes (Yarita et al. 2007, Samerpitak et al. 2014, Giraldo et al. 2014, Senwanna et al. 2021). However, V. gallopava (the type species) has been reported as an opportunistic pathogen of humans and causing infections in other warm-blooded animals, especially from birds (Revankar & Sutton 2010, de Hoog et al. 2011). Currently, this genus is supported by both morphological (sexual and asexual) and molecular data.
