花冠属的两个新种，即 C. anglusa sp。十一月及其无性型 Varicosporina anglusa sp。十一月和 C. portsaidica sp。本文根据形态学和分子证据描述了从埃及地中海沿岸分离出来的 nov. 11。这两个新种具有单隔膜子囊孢子。 Corollospora anglusa 与 C. gracilis 相似，具有狭窄的单隔膜透明子囊孢子；然而，它们的子囊和子囊孢子尺寸以及纯培养特征不同。 C. anglusa 的单子囊孢子培养物产生其无性型的分生孢子，而 C. gracilis 的无性型尚未报道。 Anglusa Varicosporina 与其他两种已知的 Varicosporina 物种不同，其分生孢子分支为丝状、矩形分支、菌丝状，并分解成两细胞或单细胞片段。 Corollospora portsaidica 在形态上与 C. cinnamomea 相似，但两个物种在子囊孢子的尺寸、形状和装饰方面有所不同。根据 LSU rDNA 区域部分序列的系统发育分析，新的花冠属物种被证实与其他类似的花冠属物种不同。
Two new species of the genus Corollospora, namely, C. anglusa sp. nov. with its anamorph Varicosporina anglusa sp. nov. and C. portsaidica sp. nov., which were isolated from the coast of the Mediterranean Sea in Egypt, are described in this article based on morphological and molecular evidence. The two new species have one-septate ascospores. Corollospora anglusa resembles C. gracilis by having narrow one-septate hyaline ascospores; however, they differ in ascomata and ascospore dimensions and in pure culture characteristics. Single-ascospore culture of C. anglusa produces the conidia of its anamorph, whereas an anamorph has not been reported for C. gracilis. Varicosporina anglusa differs from the other two known Varicosporina species by having conidial branches that are filamentous, rectangularly branched, hypha like, and disarticulated into two- or one-celled fragments. Corollospora portsaidica is morphologically similar to C. cinnamomea, but the two species differ in the dimensions, shape, and ornamentation of the ascospores. The new Corollospora species were confirmed to be divergent from other similar Corollospora species based on phylogenetic analyses of partial sequences of the LSU rDNA region.
