Fungal specimens parasitic on spider egg sacs (Araneidae sensu lato) were collected, isolated, and identified based on molecular phylogenetic analyses of five nuclear loci (ITS, LSU, TEF1, RPB1 and RPB2) combined with morphological data. In this study, one novel monotypic genus is described, Bhushaniella rubra for Thailand. Bhushaniella rubra is characterized by producing superficial perithecia. Its anamorph has a unique character by producing verticillate phialides with a slightly curved neck. A concurrent evaluation of the secondary metabolites of the mycelial extracts of the new fungus revealed the presence of picoline alkaloids of the penicolinate type, for which we propose the trivial names penicolinates F and G. Their chemical structures were elucidated by two-dimensional nuclear magnetic resonance (2D-NMR) spectroscopy and high resolution mass spectrometry (HR-MS). They only showed weak to no antibiotic activity and were devoid of significant cytotoxic effects.

Ophiocordyceps is a species-rich genus in the order Hypocreales (Sordariomycetes, Ascomycota) depicting a fascinating relationship between microbes and insects. In the present study, a new species, Ophiocordyceps indica sp. nov., is discovered infecting lepidopteran larvae from tree line locations (2,202–2,653 m AMSL) of the Kullu District, Himachal Pradesh, Indian Western Himalayan region, using combinations of morphological and molecular phylogenetic analyses. A phylogeny for Ophiocordyceps based on a combined multigene (nrSSU, nrLSU, tef-1α, and RPB1) dataset is provided, and its taxonomic status within Ophiocordycipitaceae is briefly discussed. Its genome size (~59 Mb) revealed 94% genetic similarity with O. sinensis; however, it differs from other extant Ophiocordyceps species based on morphological characteristics, molecular phylogenetic relationships, and genetic distance. O. indica is identified as the second homothallic species in the family Ophiocordycipitaceae, after O. sinensis. The presence of targeted marker components, viz. nucleosides (2,303.25 μg/g), amino acids (6.15%), mannitol (10.13%), and biological activity data, suggests it to be a new potential source of nutraceutical importance. Data generated around this economically important species will expand our understanding regarding the diversity of Ophiocordyceps-like taxa from new locations, thus providing new research avenues.

Ophiocordyceps is the largest genus in Ophiocordycipitaceae and has a broad distribution with high diversity in subtropical and tropical regions. In this study, two new species, pathogenic on lepidopteran larvae are introduced, based on morphological observation and molecular phylogeny. Ophiocordyceps fenggangensissp. nov. is characterised by having fibrous, stalked stroma with a sterile tip, immersed perithecia, cylindrical asci and filiform ascospores disarticulating into secondary spores. Ophiocordyceps liangiisp. nov. has the characteristics of fibrous, brown, stipitate, filiform stroma, superficial perithecia, cylindrical asci and cylindrical-filiform, non-disarticulating ascospores. A new combination Ophiocordyceps musicaudata (syn. Cordyceps musicaudata) is established employing molecular analysis and morphological characteristics. Ophiocordyceps musicaudata is characterised by wiry, stipitate, solitary, paired to multiple stromata, yellowish, branched fertile part, brown stipe, immersed perithecia, cylindrical asci and cylindrical-filiform, non-disarticulating ascospores.
