Notes: Helicocentralis was introduced and accomodated in Helotiales (Leotiomycetes) by Sri-indrasutdhi et al. (2015) based on morphology and the phylogenetic analysis of the combined ITS, LSU and SSU sequence data. Helicocentralis was introduced to accommodate H. hyaline as the type species, an aero-aquatic helicosporous fungal taxon which was found on semi-submerged wood in Thailand (Sri-Indrasutdhi et al. 2015). The asexual morph of Helicocentralis is characterized by short, micronematous or semi-macronematous, hyaline conidiophores, monoblastic, conical to cylindrical conidiogenous cells, and acrogenous, circinate, centrifugally coiled, non-hygroscopic, hyaline conidia (Sri-Indrasutdhi et al. 2015). It is important to note that Helicocentralis is another aero-aquatic helicosporous hyphomycetes discovered following the genera Helicodendron, Helicoma, Helicomyces, Helicoön, and Helicosporium (Markovskaja 2012; Sri-Indrasutdhi et al. 2015).

Type species: Helicocentralis hyaline Sri-indr., Chuaseehar., Boonyuen, K. Yamag., Suetrong & C.K.M. Tsui, Mycological Progress 14 (10/81): 6 (2015).

Other accepted species: Species Fungorum – search Helicocentralis.
