Parahevansia Mongkolsamrit & Noisripoom gen. nov.

Type species.

Parahevansia koratensis (Hywel-Jones) Mongkolsamrit & Noisripoom, comb. nov., Mycol. Res. 100: 1067 (1996).


Morphologically resembling the genus Hevansia , but being phylogenetically distinct.


Asexual morph: Synnemata arising from all parts of host, numerous, simple, brown at the sterile base becoming grey white with fertile part. Conidiogenous cells phialidic producing upper part of the synnemata. Phialides in a monolayer, single on basal lateral cells of synnemata, crowded, obovoid to ellipsoid with distinct necks. Conidia in chain, hyaline, smooth-walled, clavate.


Parahevansia koratensis , the type species of this genus, was originally described as species of Akanthomyces (Hywel-Jones, 1996) and later transferred to Hevansia ( Kepler et al. 2017). Our multi-gene phylogenetic analyses supported Parahevansia as a monophyletic clade with strong support (MLB = 100 / BPP = 1.00, Fig. 1 View Figure 1 ). Therefore, we introduced Parahevansia as a new genus that accommodates a single species, Pa. koratensis .
