C4D2E3080F905553A5FA9E8D27F28AA0.taxon	description	Species description. Acaulosporoid spores formed laterally on the neck of a sporiferous saccule (Fig. 5 H), singly in the substrate or occasionally within roots. Spores hyaline to white (1 A 1), in maturity greyish white (1 B 1), globose to subglobose, (55 –) 60 (– 67) μm diam, rarely ellipsoid to ovoid (57 –) 62 (– 85) μm, with two walls (sw, iw) (Fig. 5 A – F, I). Spore wall (sw) consists of two layers with 1.3 – 1.5 μm thick. Layer 1 (swl 1) short-lived, evanescent, hyaline, thin, 0.3 – 0.5 μm thick. Layer 2 (swl 2) permanent, laminated, hyaline to white (1 A 1), 0.8 – 1.0 μm thick. Inner wall (iw) consists of two, permanent, flexible to semi-flexible, (1.4 –) 1.5 (– 2.0) μm thick layers. Layer 1 (iwl 1) uniform, slightly pigmented (1 A 2), 0.8 – 1.0 μm thick. Layer 2 (iwl 2) hyaline, amorphous, 0.5 – 2.5 μm thick. None of the wall layers exhibits amyloid or dextrinoid reactions in Melzer’s reagent. Sporiferous saccule hyaline to subhyaline, subglobose to oblong, 15 – 55 × 30 – 75 µm diam, with an extremely delicate mono- to bi-layered wall continuous with the two outer layers of the outer spore wall (swl 1 - 2) and coated with adherent granular material; rarely observable in spores outside roots due to frequent collapse or detachment during extraction from the soil, except in spores with adherent soil particles or remnant root fragments; occasionally visible within root tissues, where it stains dark with Trypan blue (Fig. 5 H). The basal attachment point of the spore is marked by a semi-persistent cicatrix-like structure formed by the spore wall (Fig. 5 H). The spore content consists of a dense, hyaline, oily substance forming unevenly distributed droplets that appear prominently darker than the spore walls, especially when observed in Melzer’s reagent (Fig. 5 A). A germination shield (gs) forms from the inner wall (iw) (Fig. 5 I). This structure is difficult to observe and was only visualized laterally in spores stained in Trypan blue. Mycorrhiza with hyphae, spores, and vesicles staining dark in Trypan blue (Fig. 5 G – I). Sporocarps unknown. Glomoid spores not detected.	en	Esmaeilzadeh-Salestani, Keyvan, Queiroz, Mariana Bessa de, Mikryukov, Vladimir, Uszok, Sylwia, Goto, Bruno Tomio, Tedersoo, Leho, Magurno, Franco (2025): Morphological and phylogenetic analysis of the early-diverging lineage of Glomeromycota suggest two new genera and recombinations in Archaeosporales.
