Anthostomella culmicola W. H. Hsieh and C. Y. Chen., China-Graphics, Taichung, Taiwan: 30-32. 2000.

 Description: Mycelium immersed, subepidermal, intracellular, causing the disolouration of the host tissues, the discoloured region horizontally extending, effuse, covering numerous ascomata, visible on surface as a large amorphous patch. Ascomata depressed globose, 430-560 μm wide, 420-470 μm high including the neck, solitary, scattered, with a neak to 200 μm long and piercing through the host tissue. Clypeus surrounding and merging with the apex of neck, 130-160 μm long. Ostiolar canal to 60 μm wide, periphysate. Peridium 20-50 μm thick, composed of numerous layers of compact cells, the inner cells polygonal to ellipsoid, hyaline, the outer cells strongly depressed, pale brown.Asci cylindrical, 140-180 × 6-8 μm, unitunicate, stipitate, 8-spored, with an amyloid apical ring. Ascospores ellipsoid, 16-20 × 5-6 μm, rounded to slightly pointed at ends, dark brown, germ slit of the same length as the ascospore.

 Note: Several species of Anthostomella have been reported on Gramineae, including bamboo (Francis, 1975; Petrak & Deighton, 1952; Rappaz, 1995). None of them is close to A. culmicola. This fungus resembles A. longispora Hsieh et al. (1997) in the morphology of the ascospores, but they are quite different in the composition of ascomatal peridium. A. longispora has a peridium of textura intricate, while A. culmicola has a peridium of textura angularis. The ascospores are also wider in A. longispora.
