Abstract

Aspergillus section Candidi encompasses white- or yellow-sporulating species mostly isolated from indoor and cave environments, food, feed, clinical material, soil and dung. Their identification is non-trivial due to largely uniform morphology. This study aims to re-evaluate the species boundaries in the section Candidi and present an overview of all existing species along with information on their ecology. For the analyses, we assembled a set of 113 strains with diverse origin. For the molecular analyses, we used DNA sequences of three house-keeping genes (benA, CaM and RPB2) and employed species delimitation methods based on a multispecies coalescent model. Classical phylogenetic methods and genealogical concordance phylogenetic species recognition (GCPSR) approaches were used for comparison. Phenotypic studies involved comparisons of macromorphology on four cultivation media, seven micromorphological characters and growth at temperatures ranging from 10 to 45 °C. Based on the integrative approach comprising four criteria (phylogenetic and phenotypic), all currently accepted species gained support, while two new species are proposed (A. magnus and A. tenebricus). In addition, we proposed the new name A. neotritici to replace an invalidly described A. tritici. The revised section Candidi now encompasses nine species, some of which manifest a high level of intraspecific genetic and/or phenotypic variability (e.g., A. subalbidus and A. campestris) while others are more uniform (e.g., A. candidus or A. pragensis). The growth rates on different media and at different temperatures, colony colours, production of soluble pigments, stipe dimensions and vesicle diameters contributed the most to the phenotypic species differentiation. Taxonomic novelties: New species: Aspergillus magnus Glässnerová & Hubka; Aspergillus neotritici Glässnerová & Hubka; Aspergillus tenebricus Houbraken, Glässnerová & Hubka.

念珠菌曲霉切片专著。
念珠菌包括白色或黄色孢子的种类,主要是从室内和洞穴环境、食物、饲料、临床材料、土壤和粪便中分离出来的。它们的识别是非平凡的,因为它们的形态基本一致。本研究旨在重新评估念珠菌段的物种边界,并概述所有现有物种及其生态信息。为了进行分析,我们收集了113株不同来源的菌株。在分子分析方面,我们使用了三个管家基因(benA、CaM和RPB2)的DNA序列,并采用基于多物种聚结模型的物种划分方法。采用经典系统发育方法和系谱一致性系统发育物种识别方法进行比较。表型研究包括比较4种培养基上的宏观形态、7种微观形态特征和10 ~ 45℃温度下的生长情况。基于系统发育和表型四个标准的综合方法,所有现有的物种都得到了支持,并提出了两个新种(A. magnus和A. tenebricus)。此外,我们还提出了新名称A. netritici,以取代无效描述的A. tritici。修订后的念珠菌部分现在包括9个物种,其中一些表现出高水平的种内遗传和/或表型变异性(例如,a . subalbidus和a . campestris),而另一些则更为统一(例如,a . candius或a . pragensis)。不同培养基和温度下的生长速率、菌落颜色、可溶性色素产量、柱头尺寸和囊泡直径对表型物种分化的影响最大。分类新异:新种:magnus Aspergillus Glässnerová & Hubka;新小麦曲霉Glässnerová & Hubka;黑曲霉(Aspergillus tenebricus Houbraken) Glässnerová & Hubka。引用本文:Glässnerová K, Sklenář F, jurjeviki Ž, Houbraken J, Yaguchi T, Visagie CM, gen J, Siqueira JPZ, Kubátová A, Kolařík M, Hubka V(2022)。念珠菌曲霉切片专著。真菌学研究(02):1-51。doi: 10.3114 / sim.2022.102.01。

期刊介绍: The international journal Studies in Mycology focuses on advancing the understanding of filamentous fungi, yeasts, and various aspects of mycology. It publishes comprehensive systematic monographs as well as topical issues covering a wide range of subjects including biotechnology, ecology, molecular biology, pathology, and systematics. This Open-Access journal offers unrestricted access to its content. Each issue of Studies in Mycology consists of around 5 to 6 papers, either in the form of monographs or special focused topics. Unlike traditional length restrictions, the journal encourages submissions of manuscripts with a minimum of 50 A4 pages in print. This ensures a thorough exploration and presentation of the research findings, maximizing the depth of the published work.
