Aquadictyospora

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

Index Fungorum number: IF 553861

 

Saprobic on submerged wood. Sexual morph: Undetermined. Asexual morph: Conidiomata on natural substratum sporodochial, superficial, compact, scattered, circular or subglobose, dark brown to black, velvety. Mycelium immersed, consisted of septate, hyaline hyphae. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, monoblastic. Conidia ellipsoidal to broadly clavate, composed of medium brown, appressed cells, rounded and brown at the apex, oval to subglobose and hyaline at the base, muriform, cheiroid, non-complanate, without appendages (Li et al. 2017a).

 

Type species: Aquadictyospora lignicola Z.L. Luo, W.L. Li, K.D. Hyde & H.Y. Su, in Li et al., Mycosphere 8(10): 1591 (2017)

 

Notes: The monotypic genus Aquadictyospora was intro- duced to accommodate a freshwater species A. lignicola col- lected from China (Li et al. 2017b; Bao et al. 2018). Aqua- dictyospora differs from other genera in Dictyosporiaceae by its basal hyaline cell and conidia without appendages (Li et al. 2017b; Bao et al. 2018). Aquadictyospora nested in Dictyosporiaceae with high bootstrap support (Dong et al. 2020).
