Ceratosphaeria ordinata  

Ascomata 170-300 µm diam, the body ± globose, ± superficial, strongly aggregated, black, leathery, faintly roughened; the neck strongly papillate, 40-60 µm long, tapering towards the apex, black, periphysate. Peridium composed of outer layers of thick-walled almost black cells intermediate between textura epidermoidea and angularis, the cells rarely more than 4 µm diam, merging into poorly-defined textura intricata in the neck region, and an inner layer of ± hyaline cells. Interascal tissue composed of copious fairly thick-walled persistent simple paraphyses to ca 3 µm diam. Asci 94-108 x 7-9.5 µm, narrowly cylindric-clavate, the base gradually tapered, thin-walled except at the apex, the apex obtuse but truncate within the ring, which is ca 2.5 µm diam and 1 µm thick, 8-spored. Ascospores arranged biseriately, 37-44 x 5-6 µm, narrowly fusiform, ± straight, the ends acute and sometimes attenuated, hyaline, fairly thin-walled, becoming ± equally 11- to 15-septate, constricted at the septa; smooth, without a gelatinous sheath or appendages.
