Distoseptisporales

Distoseptisporales Z.L. Luo, H.Y. Su & K.D. Hyde

Index Fungorum number: IF 555640, Facesoffungi number: FoF 05412

 

Sexual morph: Undetermined. Asexual morph: Mycelium mostly immersed, composed of branched, septate, smooth, pale brown hyphae. Conidiophores macronematous, mononematous, septate, unbranched, erect, straight or flexuous, smooth. Conidiogenous cells monoblastic, integrated, determinate, terminal, cylindrical. Conidia acrogenous, solitary, euseptate or distoseptate, obclavate or cylindrical with rounded apex. Conidial secession schizolytic. (Description taken from Luo et al. 2019)

 

Type family: Distoseptisporaceae K.D. Hyde & McKenzie

 

Notes: The monotypic order Distoseptisporales is placed in the class Sordariomycetes, subclass Diaporthomycetidae and comprises a single family Distoseptisporaceae and Aquapteridospora (Distoseptisporales genera incertae sedis). Distoseptisporaceae was established by Su et al. (2016) with a single genus Distoseptispora based on morphology and phylogeny. Yang et al. (2015) introduced Aquapteridospora and was placed as Diaporthomycetidae genera incertae sedis. Luo et al. (2019) raised Distoseptisporaceae to Distoseptisporales based on the morphology and phylogenetic analysis of combined LSU, SSU, rpb2 and tef1 sequence data. The divergence time for Distoseptisporales has been estimated as 102 MYA, which falls in the range of family status (Hyde et al. 2020). The status may need revision following further study. Currently there is one family and one genus in this order (Hyde et al. 2020).
