| Description： |
Perithecia solitary, immersed, subglobose, 150-200 μm high, 250-375 μm wide, ostiolate with upwardly directed, hyaline, periphyses. Perithecial wall 25-38 μm wide, composed of pseudoparenchymatous cells forming a textura angularis. Asci broadly cylindrical to clavate, 8-spored, short-stalked, thin-walled, non-fissitunicate, evanescent, 95-105 × 15-25 μm, without any discernible apical structures. Paraphyses deliquescent. Ascospores cylindrical to narrowly fusiform, fasciculate, hyaline guttulate, straight or mostly slightly curved, mostly 3-septate but may become up to 6 – or rarely 8-septate when old, 60-95 (100) × 5.0-7.5 μm. Rarely asci with abnormal aseptate ascospores morphologically resembling ascospores in some Glomerella species in size and in their ellipsoidal shape particularly those of G. cingulata (Stoneman) Spauld. & H. Schrenk are found mixed with asci with the normal 3-septate ascospores in some perithecia. These abnormal ascospores are 10-12 × 4.5-5.0 μm. Generally 2-3 ‘abnormal spored’ asci are formed in some perithecium containing 12-15 asci. The first septum in the ascospore is always median followed by development of other septa. Single spore isolations of both abnormal and normal ascospores produced morphologically identical teleomorph and anamorph. | |||
