Bhatiellae Wanas., Camporesi & K.D. Hyde, in Wanasinghe et al., Fungal Diversity: 10.1007/s13225-018-0395-7, [107] (2018)

Index Fungorum number: IF 554171; Facesofungi number: FoF 04013

Etymology: In honour of Prof. Bhat Jayarama Darbhe, for his immense contribution to mycology.

Saprobic in terrestrial habitat. Sexual morph: Undetermined. Asexual morph: hyphomycetous forming on surface host epidermis. Sporodochia with cushion-like pseudoparenchymatous cells at the base, composed of compact, fasciculate, foot-like cells at the base, with tightly aggregated, parallel, cylindrical conidiophores. Conidiophores macronematous, mononematous, caespitose, erect to flexuous, unbranched, aseptate, torsive, brown to dark brown, smooth-walled, largely ampulliform at the base, undulated at the upper part. Conidiogenous cells polyblastic, sympodial, integrated, terminal, cylindrical, undulate, with large, cicatrized scars. Conidia acropleurogenous, solitary, simple, straight or moderately curved, cylindrical or ellipsoidal, brown to olivaceous brown when mature, euseptate, 5–8-distoseptate, smooth-walled, widest at the middle.

Type: Bhatiellae rosae Wanas., Camporesi, E.B.G. Jones & K.D. Hyde

Notes: Two hyphomycetous genera were listed in Phaeosphaeriaceae viz. Harpophora and Mauginiella by Wijayawardene et al. (2012). Mauginiella was treated as an asexual state of Phaeosphaeria by Abdullah et al. (2005). The phylogenetic placement of this genus has not been confirmed in Pheaosphaeriaceae and Phookamsak et al. (2014) excluded it from the family. However, Wijayawardene et al. (2017) still treated the genus in Phaeosphaeriaceae. There are only ITS sequences of M. scaettae available in GenBank. Phylogenetic analysis of the genus is needed to clarify its taxonomic position. In our primary ITS analyses it grouped near Chaetosphaeronema. Harpophora was reported as the asexual morph of Ophiobolus. Based on morphological characters, Phookamsak et al. (2014) excluded Hadrospora from Phaeosphaeriaceae and tentatively placed the genus in Trematosphaeriaceae. Recently, Wijayawardene et al. (2017) kept harpophora-like asexual morphs in Magnaporthaceae, which are similar to Gaeumannomyces and Magnaporthe.

In this study, we collected a hyphomycetous isolate which is nested in between Neosulcatispora and Setophoma in our multi-gene phylogenetic analyses. We treat this new isolate as a new genus, Bhatiellae in Phaeosphaeriaceae.
