摘要

从墨西哥韦拉克鲁斯中部的Manilkara zapota中分离到一种新的烟霉Chaetocapnodium zapotae。ITS+LSU核rDNA序列分析表明，该分离物在属水平上与Chaetocapnodium insulare和Chaetocapnodium placitae属于同一支系。形态学检查证实新种与岛草的不同之处在于无性别形态和叶柄上无刚毛。与placitae相比，zapotae的其他特征是其柱头尺寸范围较窄，菌丝和分生孢子的尺寸范围较宽，柱头颜色为深褐色。

Chaetocapnodium zapotae sp. nov. on Manilkara zapota in central Mexico

A new sooty mould, Chaetocapnodium zapotae, was isolated from Manilkara zapota in central Veracruz, Mexico. An analysis of ITS+LSU nuclear rDNA concatenated sequences of our isolate revealed taxonomic identity at the genus level located in the same clade as Chaetocapnodium insulare and Chaetocapnodium placitae. Morphological examination confirmed that the new species differs from C. insulare in the absence of the sexual morph and the absence of setae on the pycnidia. Additional characters distinguishing C. zapotae from C. placitae are its narrower pycnidial size range, wider size ranges for the hyphae and conidia, and the dark brown color of its pycnidia.
