Didymellocamarosporium

Didymellocamarosporium Wijayaw., Camporesi, Bhat & K.D. Hyde, in Wijayawardene et al., Fungal Diversity: 10.1007/s13225-016-0360-2, [100] (2016)

Index Fungorum number: IF 551771; Facesofungi number: FoF 01468

Etymology: Named for its morphological similarity to the genus Camarosporium and its placement in Didymellaceae.

Saprobic on dead branches of Tamaricaceae (Dicotyledons). Sexual morph: Undetermined. Asexual morph: Conidiomata pycnidial, immersed, globose, unilocular, solitary to gregarious, dark brown to black, ostiolate. Ostiole papillate, central, single, circular. Conidiomata wall with outer layer composed of thick-walled, dark brown cells of textura angularis, inner layer with hyaline cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, annellidic, discrete, determinate, smooth, hyaline, formed from the innermost layer of pycnidial wall cells. Conidia oblong, muriform, with 3–5 transverse and 1–5 longitudinal septa, continuous or occasionally constricted at septa, straight to slightly curved, rounded at both ends, medium to dark brown, smooth-walled.

Type species: Didymellocamarosporium tamaricis Wijayaw., Camporesi, D.J. Bhat & K.D. Hyde 2016

Notes: Our strain is a camarosporium-like taxon (MFLUCC 14-0241) that groups in Didymellaceae and does not cluster with other species. Currently there are no camarosporium-like taxa reported in Didymellaceae (Wijayawardene et al. 2014), thus we introduce Didymellocamarosporium. (Wijayawardene et al. 2016)
