Type genus.
Planticonsortium C. Walker & D. Redecker.
Description.
Emanating hyphae 0.5–4 μm diam., forming colourless to brown chlamydospores (10–12 μm, up to 35 μm diam.), sometimes rope-like strands; appressoria swollen, frequently with several thin hyphae giving an insect-like appearance. Intraradical mycelium 0.5–4 μm diam., smooth to angular, with (sub-) globose swellings, forming comb-like (ctenoid), fan-shaped, palmate, antler-like, digitate or feather-like structures appearing clasped around epidermal and cortical cells; forming finely branched arbuscules. All hyphae stain darkly in acidic blue stains, more strongly for extraradical hyphae. Monophyletic group in Densosporales (Fig. 2 View Figure 2 , Suppl. materials 3, 4).
Notes.
Planticonsortiaceae covers roughly one third of Endogonomycetes reads based on LSU (Suppl. material 3) and SSU (Suppl. material 4), but is poorly represented in the ITS dataset. This may be due to the highly divergent and relatively long ITS region (800–1200 bases). Based on the LSU phylogram, Planticonsortiaceae harbours seven genus-level groups with> 100 putative species. The description is adapted from Walker et al. (2018).
