Durotheca depressa (BCC28073). A. Stromata. B. Stromata with ostioles: arrow = ostioles. C. Deep ostiole: arrow= deep ostiole. D. Perithecia. E–H. Ascospores. Bars: A = 1.5 mm; B = 1.0 mm; C = 0.5 mm; D = 1.0 mm; E-H = 5.0 µm. (i.e. the narrow, undulating stromata with ostioles in deep depressions), and the phylogenetic data corroborates the distinction. We have chosen this taxon as type of Durotheca since we consider it of value to have DNA sequences from type material.
