Between 2002 and 2017, asexual morphs of powdery mildews (Erysiphales) were collected in Thailand from the following hosts: Cassia fistula, Castanopsis argyrophylla, Durio zibethinus, Jatropha curcas, Kydia calycina, Hevea brasiliensis, Hodgsonia macrocarpa, Mallotus philippinensis, Mimosa pudica, Nephelium lappaceum, Tamarindus indica and Ziziphus jujuba. Combined molecular and morphological analyses revealed that all these specimens belong to Erysiphe quercicola. Sequences retrieved from these powdery mildews are nested within the E. quercicola clade. These results show that Erysiphe quercicola may form its asexual morph on a very broad range of hosts belonging to various plant families, particularly in the tropics, in contrast to its sexual morph which is confined to oak species (Quercus, Fagaceae). Cassia fistula, Castanopsis argyrophylla, J. curcas, K. calycina, H. macrocarpa, M. philippinensis, M. pudica, T. indica and Z. jujuba are new host records for E. quercicola worldwide.

泰国白粉菌无性变种寄主

2002 年至 2017 年间，在泰国从以下寄主中收集了白粉病 (Erysiphales) 的无性变体：Cassia fistula、Castanopsis argyrophylla、Durio zibethinus、Jatropha curcas、Kydia calycina、Hevea brasiliensis、Hodgsonia p. lappaceum、Tamarindus indica 和 Ziziphus jujuba。结合分子和形态分析表明，所有这些标本都属于 Erysiphe qurcicola。从这些白粉病中提取的序列嵌套在 E. quercicola 进化枝中。这些结果表明 Erysiphe qurcicola 可以在属于各种植物科的非常广泛的宿主上形成其无性变体，特别是在热带地区，这与它的有性变体仅限于橡树种（栎属，壳斗科）形成对比。决明子瘘，栲树，J.
