Spores glomoid, arising blastically at tips of subtending hyphae (Fig. 2 A, B, F, G) branched from a parent hypha continuous with a mycorrhizal extraradical hypha. Spores hyaline; globose to subglobose; (23 –) 31 (– 39) µm diam; rarely ovoid to oblong, 14 – 33 × 26 – 71 µm; with one subtending hypha (Fig. 2 A – G). Spore wall composed of three hyaline layers (layers 1 – 3; Fig. 2 D – G). Layer 1, forming the spore surface, uniform (without visible sublayers), semi-permanent, (0.8 –) 1.3 (– 2.0) µm thick when smooth, often with local thickenings, (1.2 –) 2.1 (– 3.8) µm thick, randomly distributed on the spore surface, rarely strongly or completely sloughed off in aged spores (Fig. 2 D – G). Layer 2 laminate, permanent, smooth, (1.0 –) 1.4 (– 2.0) µm thick, consisting of very thin, <0.5 µm, sublayers tightly adherent to and not separating from each other even in vigorously crushed spores (Fig. 2 D – G). Layer 3 uniform, permanent, smooth, ca. 0.6 – 0.8 µm thick, usually tightly adherent to the inner surface of layer 2 and, therefore, difficult to detect. Layers 1 – 3 do not stain in Melzer’s reagent (Fig. 2 E – G). Subtending hypha hyaline; straight or recurved, usually cylindrical to funnel-shaped, rarely slightly constricted at the spore base, (3.8 –) 5.7 (– 9.5) µm wide at the spore base (Fig. 2 A, B, F, G). Wall of subtending hypha hyaline; (1.6 –) 2.2 (– 2.9) µm thick at the spore base; composed of three layers continuous with spore wall layers 1 – 3 (Fig. 2 F, G). Pore (1.0 –) 1.9 (– 5.8) µm diam, usually open (Fig. 2 F), very rarely occluded by a curved septum connecting the inner surfaces of subtending hyphal wall layer 3; septum 0.4 – 0.6 µm thick, located ca. 2.0 µm below the spore base (Fig. 2 G). Sterile hyphae hyaline, (2.8 –) 4.4 (– 5.2) µm wide (Fig. 2 B, C).

Differs from other genera of Dominikiaceae in (i) having subtending hyphae with a strong bend and locally very narrow lumen due to large thickening present on the inner surfaces of the subtending hyphal walls and (ii) nucleotide composition of sequences of the 45 S nuc rDNA region (see “ Discussion ” for details).	en	Błaszkowski, Janusz, Zubek, Szymon, Milczarski, Paweł, Malinowski, Ryszard, Niezgoda, Piotr, Goto, Bruno Tomio (2025): New taxa and a combination in Glomerales (Glomeromycota, Glomeromycetes).

Layer 4 uniform, flexible to semi-flexible, smooth, concolorous with or slightly lighter than layer 3, (0.8 –) 1.0 (– 1.3) µm thick, usually only slightly separating from the lower surface of layer 3 even in vigorously crushed spores (Figs 3 B – H, 4 A, B). Layers 1 – 4 do not stain in Melzer’s reagent (Fig. 3 B – H). Subtending hypha concolorous with or slightly lighter than the spores; straight or recurved, usually cylindrical to funnel-shaped, rarely slightly constricted at the spore base, (9.6 –) 14.2 (– 20.4) µm wide at the spore base (Figs 3 A, B, D – H, 4 B). Walls of subtending hypha concolorous with or slightly lighter than the spores; usually with thickenings of unequal size, (5.8 –) 7.2 (– 11.0) µm vs. (4.0 –) 5.1 (– 6.0) µm thick, present on the inner, opposite surfaces of the walls, making the subtending hyphal lumen more or less curved and narrow when seen in a plan view (Fig. 3 A, D, E, H); less often, both walls have the same or similar thickness, (4.0 –) 6.3 (– 8.1) µm (Fig. 3 G); subtending hyphal walls composed of four layers continuous with spore wall layers 1 – 4 (Fig. 3 B, D, E – H).
