Correll，JC，Gordon，TR，and Elliott，VJ 1987.加州牛内丝壳的寄主范围、特异性和生物统计学测量。第71章：一个女人在1983-1985年期间，在加州的所有主要番茄种植区的番茄上发现了由鞑靼内丝孢霉（=鞑靼拟粉孢霉）引起的番茄白粉病。除番茄外，该病原体还在四种作物宿主（辣椒、棉花、朝鲜蓟和洋葱）和六种杂草上发现。对L. taurica在所有寄主上相似，包括内生菌丝体、二型分生孢子（梨形和圆柱形）、长且经常分枝的分生孢子梗以及单生或短链的分生孢子。朝鲜蓟菌株既有内生菌丝体，也有附生菌丝体。分生孢子的大小有很大的不同菌株。分生孢子的平均大小为71.4-49.7 × 24。梨形分生孢子和圆柱形分生孢子分别为1-16.6和65.2-44.6 × 227 -162 μ m。供试的蒜氨酸盐除洋蓟中的蒜氨酸盐外，均能侵染番茄，代表了病原菌的一个生理小种。
Correll, JC, Gordon, TR, and Elliott, VJ 1987. Host range, specificity, and biometrical measurements of Leveillula taurica in California. Plant Disease 71: 248-251.Powdery mildew of tomato caused by Leveillula taurica (= Oidiopsis taurica) was found on tomato in all of the major tomato-growing regions of California during 1983-1985. In addition to tomato, the pathogen was found on four crop hosts (pepper, cotton, artichoke, and onion) and six weed species. The morphological characteristics of L. taurica were similar on all hosts and included endophytic mycelium, dimorphic conidia (pyriform and cylindrical), long and often branched conidiophores, and conidia borne singly or in short chains. Isolates from artichoke had both endophytic and epiphytic mycelium. Conidial size varied considerably among the isolates. The range of mean conidial measurements was 71.4-49.7 X24. 1-16.6 and 65.2-44.6 X227-162 um for the pyriform and cylindrical conidia, respectively. Allisolates tested except the one from artichoke were able to infect tomato and apparently represent one physiological race of the pathogen.
