Tamhinispora
Tamhinispora Rajeshk. & Rah. Sharma, Mycosphere 4(2): 166 (2013).
Index Fungorum number: IF 803105; Facesoffungi number: FoF 08385, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on host. Sexual morph: Unknown. Asexual morph: Colonies effuse, blackish brown to black. Mycelium mostly semi-immersed or immersed, single or interwoven. Stroma none. Setae and hypopodia absent. Conidiophores absent, Conidiogenous cells, semi-macronematous, unbranched, intercalary in hyphae, almost sessile. Conidia solitary, dry, simple, mostly ovoid or irregular, dictyoseptate, smooth. Young conidia pale to dark brown with or without appendages, mature conidia dark brown to blackish with apical appendages. Apical appendages rudimentary or well developed, arising from tip of conidia, diverging or radiating, pale to dark brown, septate, tip rounded (adapted from Rajeshkumar & Sharma 2013).
Type species: Tamhinispora indica Rajeshk. & Rah. Sharma
Notes: Tamhinispora is characterised by mostly ovoid and dark brownish black or black conidia with radiating apical appendages, which are septate, pale brown and arising from the conidial tip. Tamhinispora is unique and differs from similar genera such as Ernakulamia, Pseudoacrodictys, Petrakia, Biconiosporium, Pseudopetrakia and Manoharachariella. Tamhinispora resembles Ernakulamia in having reduced intercalary conidiogenous cells, diverging or radiating appendages and dictyoseptate conidia but differs in having monoblastic conidiogenesis and conidial secession is rhexolytic compared to the monotretic and schizolytic conidiogenesis in Ernakulamia. Tamhinispora can also be distinguished from similar genera based on DNA sequence data. Tamhinispora is a distinct and well-supported genus in Tubeufiaceae. Molecular markers available for Tamhinispora are ITS and LSU.
