Astrosphaeriella pallidipolaris C.Y. Chen and H.W. Hsieh, Bot. Bull. Acad. Sin. 45: 174, 2004.
   
 
 
 
 
　Description： Ascomata evenly scattered, immersed, with only the ostiolar region erumpent through the host tissue, 580-760 μm wide, 450-520 μm high, usually flattened at base, apex compressed with a slit-like ostiolum, or sometimes papillate. Peridium at ostiolar region melanized and thickest, hyphae interwoven with host tissue, merging with the lateral and upper part of peridium to give an appearance of clypeus, peridium at sides brown, cells compressed, occasionally in palisade-like arrangement at basal corner, peridium at base usually reduced Asci clavate, 140-170 × 16-20 μm, stalk various in length, up to 50 μm long, 8-spored. Pseudoparaphyses embedded in gelatinous matrix, frequently branched and anastomosing, 1-1.5 μm wide. Ascospores ellipsoid to fusiform, 38-48 × 8-10 μm, rounded at ends, striate, 5(6)-septate, first septum supra-median, constricted, brown with the end cells paler, overlapping biseriate in the upper part of ascus, becoming uniseriate below.

　Note： The ascomata of this species recall those of A. striaspora, as being subglobose with flattened base. This fungus has specially pigmented ascospores (paler at end cells) and a slit-like ostiolum. These characters are significantly different from other species in Astrosphaeriella.
