A new glomeromycotan fungus, Archaeospora ecuadoriana sp. nov., was found in the south Ecuadorian mountain rainforest region, a global plant biodiversity hotspot. It was cultivated as single spore isolate originating from nursery-grown native tree seedlings inoculated with mixed soil from pristine forest and agricultural fields. The new species is known from the Loja area, southern Ecuador, at about 2100 m above mean sea level (mamsl) and has been detected in potato roots from an Andean region in Peru at 2658 mamsl by previous molecular data. The fungus forms small, colourless to frosted white, mainly globose spores, averaging 61 × 60 μm, formed singly or very rarely in clusters. There is no reaction to Melzer’s reagent, other than a slight unspecific overall yellow iodine staining. The spores are very similar to those of Archaeospora trappei and A. schenckii. However, molecular phylogenetic analysis shows the species to be clearly separate from all other described Archaeospora species. The analysis of the available Archaeospora sequence data shows that sequences of Palaeospora spainiae, of the monospecific genus Palaeospora, cluster within the genus Archaeospora. Palaeospora therefore is synonymised with Archaeospora and P. spainiae is transferred to Archaeospora, as A. spainiae comb. nov.

厄瓜多菌古菌 十一月 从厄瓜多尔的一个山区生物多样性热点地区转移过来，然后将西班牙古龟从西班牙古猿A. spainiae梳子转移到Archaeospora。十一月

一种新的肾小球菌真菌，Archeospora ecuadorianasp。十一月，在厄瓜多尔南部山区雨林地区发现，这是全球植物生物多样性热点。它是作为单孢子分离株栽培的，起源于苗圃生长的原生树苗，接种了来自原始森林和农田的混合土壤。从厄瓜多尔南部的洛哈地区已知该新物种，该物种位于平均海平面（mamsl）上方约2100 m处，并且根据先前的分子数据已在秘鲁安第斯地区2658 mamsl的马铃薯根中发现了新物种。真菌形成小，无色至磨砂白色，主要为球形孢子，平均61×60μm，单个或很少成簇形成。除了轻微的不确定的整体黄色碘染色外，对梅尔泽试剂没有反应。孢子与古细菌Artrapeostrapa trappei和申克A.。但是，分子系统发育分析表明该物种与所有其他已描述的古细菌物种明显分离。对可用的古菌序列数据的分析显示，西班牙古菌属的单特异性古菌属序列聚集在古菌属内。Palaeospora因此synonymised与Archaeospora和P. spainiae被转移到Archaeospora，如A. spainiae梳。十一月
