Abstract

The ascal wall of Leptosphaeria senegalensis typically belongs to the bitunicate type; in its fin al state it comprises an exoascus separated from the endoascus by a clear space. The three-layered endoascus is formed of fibrillae whose most internal are accordion-like folded. The ascospores have a complex wall; from the interior to the exterior it comprises: an endospore, an irregularity thickened epispore, a perispore, and an ectospore thickened in a cap at the posterior end of the spore. The comparison of ascospores of two "real" Leptosphaeria (L. acuta et L. maculans) with those of L. senegalensis shows that the latter species must no longer be included in the genus Leptosphaeria.

摘要

塞内加尔小球腔菌的子囊壁通常属于双囊壁类型；在其最终状态下，它由一个外囊膜和一个内囊膜组成，两者之间有一个清晰的空间。三层的内囊膜由纤维状结构形成，其最内层呈手风琴状折叠。子囊孢子有一层复杂的壁；从内部到外部，它包括：一个内孢子、一个不规则增厚的外孢子、一个周孢子和一个在孢子后端呈帽状增厚的外生孢子。将两种“真正的”小球腔菌（尖锐小球腔菌和黄斑小球腔菌）的子囊孢子与塞内加尔小球腔菌的子囊孢子进行比较表明，后一个物种不应再被归入小球腔菌属。
