No full textNeokamalomyces Sanjay & Raghv. Singh, gen. nov. MycoBank: MB 843767 Type species:— Neokamalomyces indicus Sanjay & Raghv. Singh. Diagnosis:— Differs from Parapallidocercospora by its very well developed pycnidial conidiomata with a central ostiolum, and hyaline conidiogenous cells lining the inner cavity. Etymology:— Prefix ‘ Neo ’ meaning new and genus suffix ‘ kamalomyces ’ based on the living legend Professor Kamal (DDU Gorakhpur University, Gorakhpur, India), a renowned mycologist and monographer of Cercosporoid Fungi of India. Conidiomata pycnidial, brown to dark brown, subepidermal, epigenous, numerous in each lesion, immersed to erumpent, subglobose to globose, with a central ostiolum, releasing a hyaline conidial mass; outer cells with brown, somewhat thickened walls, inner cells hyaline, thin-walled. Ostiole single, circular, central. Conidiophores reduced to conidiogenous cells lining the inner cavity. Conidiogenous cells hyaline, tightly aggregated, cylindrical and tapering gradually toward the apex, ampulliform or lageniform with a relatively long neck, holoblastic, proliferating sympodially, smooth; scars unthickened. Conidia cylindrical, weakly to strongly curved, or flexuous, gradually attenuated to a rounded apex, gradually or more abruptly attenuated into a broadly truncate base, septate, not or indistinctly constricted around the septa, hyaline to light olivaceous, hila unthickened to slightly thickened. Sexual morph not seen.Published as part of Yadav, Sanjay, Verma, Sanjeet Kumar, Singh, Raghvendra, Singh, Vinay Kumar, Chaurasia, Balmukund, Singh, Paras Nath & Kumar, Shambhu, 2022, Neokamalomyces indicus gen. nov., sp. nov.
