Pseudofusicolla was introduced after re-examining herbarium material of four strains, which provisionally retained as “Fusarium”, and based on multigene phylogeny (Triest et al. 2016). The genus was typified as Pseudofusicolla belgica. Pseudofusicolla belgica was isolated from recycled water from air conditioners and spray humidifiers (Triest et al. 2016). The asexual morph of Pseudofusicolla on SNA is characterized by branched conidiogenous cells or conidiogenous cells scattered along branched hyphae. Conidiogenesis began with phialides after a few days. Microconidia are strongly falcate, aseptate or 1-septate, while macroconidia are strongly falcate, smooth-walled, aseptate to three-septate. Chlamydospores are present. The sexual morph is undetermined. Aerial mycelium on PDA is dense, sterile and white to pale orange. Pionnotal growth can be observed on SNA with or without fragments of carnation leaves.
Type species: Pseudofusicolla belgica D. Triest
Other accepted species: This genus is monotypic
