Abstract

Abstract. A recent molecular phylogeny of Amanita recognises three subgenera and 11 sections. Members of subgenus Amanitina are characterised by amyloid spores and a mycorrhizal habit. Section Arenariae falls within this subgenus. Members of this section are known only from southern Australia; they are either sequestrate (secotioid) or agaricoid and lack clamp connections. We describe the following three additional secotioid species: Amanita arenarioides Bougher, E.M.Davison & Giustiniano, A. compacta Bougher, E.M.Davison & Giustiniano and A. pseudoarenaria E.M.Davison, Giustiniano & Bougher, which are separated on macroscopic appearance, spore shape and genetic sequences. We also describe two agaricoid species, namely, A. pupatuju E.M.Davison, Giustiniano, McGurk & E.L.J.Watkin, and A sabulosa E.M.Davison & Giustiniano, which are separated on bulb shape and genetic sequences. We provide expanded descriptions of A. arenaria (O.K.Mill. & E.Horak) Justo and A. griselloides D.A.Reid; we also synonymise A. dumosorum D.A.Reid with A. peltigera D.A.Reid. A revised diagnosis and description of section Arenariae is provided, together with a key to currently recognised member of this section.

摘要鹅膏菌最近的分子系统发育鉴定出三个亚属和11个部分。鹅膏菌亚属的成员具有淀粉样孢子和菌根习性。Arenariae部分属于这个亚属。本节成员仅来自澳大利亚南部；它们要么是螯合的（secotioid），要么是无神经节的，并且缺乏夹紧连接。我们描述了以下三个额外的secotioid物种：Amanita arenarioides Bougher，E.M.Davison&Giustiano，A.compacta Bougher、E.M.Davison&Giustiniano和A.pseudoarenaria E.M.Davisson，Giustinino&Bougher。它们在宏观外观、孢子形状和遗传序列上是分离的。我们还描述了两个无翅目物种，即A.pumptuju E.M.Davison、Giustiano、McGurk&E.L.J.Watkin和A.sabulosa E.M.Davison&Giustianno，它们在球茎形状和遗传序列上是分开的。我们提供了A.arenaria（O.K.Mill.&E.Horak）Justo和A.griseloides D.A.Reid的详细描述；我们还将A.dumosorum D.A.Reid与A.peltigera D.A.Reid.同义。提供了Arenariae部分的修订诊断和描述，以及该部分目前公认成员的钥匙。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
