虽然直到最近才被描述，但在文献中，博宁炭疽菌是一种炭疽病病原体或世界范围内各种寄主植物的内生菌。在石蒜科、兰科、山茶科和茄科植物上表现尤为突出。文献报道和利用ITS序列数据进行的初步研究表明，博宁华支睾吸虫代表了一种复合体。用ITS、ACT、TUB2、CHS-1、GAPDH、HIS3、CAL等多位点分子系统发育分析方法，对86株已鉴定为博宁梭菌及相关菌株的菌株进行了系统发育分析，共分出18个分支。这些分支在这里被识别为单独的种，包括C.boninense S.Str.，C.hipestri，C.karstii和12个以前未被描述的种，C.annellatum，C.beeveri，C.brassicola，C.brasiliense，C.colombiense，C.constraum，C.cymbidiicola，C.dacrycarpi，C.novae-zelandiae，C.oncidii，C.parsonsiae和C.torulosum。其中七个新物种仅在新西兰已知，这可能反映了采样偏差。建立了新的组合--叶冠锦鸡儿，并将其表型化为龙冠锦鸡儿，更名为佩奇锦鸡儿。博宁草属植物复合体的典型特征是分生孢子细胞，分生孢子细胞具有相当明显的轴周加厚，有时还延伸形成新的分生孢子位置或环状分生孢子，以及具有明显的基生痕的分生孢子。许多物种在人工培养中形成真性体。新组合--叶状炭疽菌(Colletotrichum phllanthi(H.Surendranath Pai)Damm，P.F.canon&Cous.)更名-C.Petchii Damm，P.F.Canon&Cous。新种--毛叶锦鸡儿C.annellatumDamm，P.F.Canon&Cous，C.beeveri Damm，P.F.Canon，Cous，P.R.Johnst.和B.Weir，Brassicola Damm，P.F.canon&Cous，C.Brasiliense Damm，P.F.canon，C.colombiense Damm，P.F.Canon，Cous，C.condicum Damm，P.F.Canon，Cous，P.R.Johnst.首页--期刊主要分类--期刊细介绍--期刊题录与文摘--期刊详细文摘内容首页--期刊主要分类--期刊细介绍--期刊题录与文摘--期刊详细文摘内容&B.Weir，C.novae-zelandiae Damm，P.F.Canon，Cous，P.R.johnst.和B.Weir，C.oncidii Damm，P.F.canon&Cous，C.parsonsiae Damm，P.F.Canon，Cous，P.R.Johnst。&B.Weir，C.torulosum Damm，P.F.Canon，Cous，P.R.Johnst.&B.Weir.表型：表型--龙眼隐翅虫。
Although only recently described, Colletotrichum boninense is well established in literature as an anthracnose pathogen or endophyte of a diverse range of host plants worldwide. It is especially prominent on members of Amaryllidaceae, Orchidaceae, Proteaceae and Solanaceae. Reports from literature and preliminary studies using ITS sequence data indicated that C. boninense represents a species complex. A multilocus molecular phylogenetic analysis (ITS, ACT, TUB2, CHS-1, GAPDH, HIS3, CAL) of 86 strains previously identified as C. boninense and other related strains revealed 18 clades. These clades are recognised here as separate species, including C. boninense s. str., C. hippeastri, C. karstii and 12 previously undescribed species, C. annellatum, C. beeveri, C. brassicicola, C. brasiliense, C. colombiense, C. constrictum, C. cymbidiicola, C. dacrycarpi, C. novae-zelandiae, C. oncidii, C. parsonsiae and C. torulosum. Seven of the new species are only known from New Zealand, perhaps reflecting a sampling bias. The new combination C. phyllanthi was made, and C. dracaenae Petch was epitypified and the name replaced with C. petchii. Typical for species of the C. boninense species complex are the conidiogenous cells with rather prominent periclinal thickening that also sometimes extend to form a new conidiogenous locus or annellations as well as conidia that have a prominent basal scar. Many species in the C. boninense complex form teleomorphs in culture. New combination - Colletotrichum phyllanthi (H. Surendranath Pai) Damm, P.F. Cannon & Crous.
