Astrosphaeriella exorrhiza Boise in D. Hawksw. and Boise, Sydowia 38: 117. 1985.
   
 
 
 
 
　Description： Ascomata scattered, erumpent through the host tissue to become superficial, conical, 600-1000 μm wide, 500-800 μm high, apex non-papillate to slightly papillate, base flattened, basally surrounded with teeth-like ruptured host tissue. Peridium at sides carbonaceous, composed of melanized and opaque cells, much reduced at base, with palisade-like cells at the rim margin. Asci cylindrical, 180-230 × 10-12 μm, sessile to short-stalked, 8-spored. Pseudoparaphyses embedded in gelatinous matrix, frequently branched and anastomosing, 1-1.5 μm wide. Ascospores ellipsoid to fusiform, 70-85 × 7-10 μm, acute at ends, dark brown, smooth, (3-)5(6)-septate, the first septum largely median and slightly constricted, overlapping bi-triseriate in ascus, occasionally with inconspicuous up to 1 μm long mucilaginous appendages at ends.

　Note： The appendages of ascospores were not reported by Hawksworth & Boise (1985) in A. exorrhiza, whereas Hyde and Fr?hlich (1997) described their presence. The ascospores of Taiwan material possess appendages; however they are not readily observable and only occur on some ascospores.
