Maximum Likelihood phylogeny of SSU rRNA gene V4 region OTUs from tropical soil and European marine (Biomarks) samples. The OTUs are aligned to reference sequence dataset of long‐ and short‐branch Microsporidia, metchnikovellids, rozellids, other clades of environmental sequences, and representative aphelids and fungi with a holozoan outgroup. Light and dark grey shading indicates extent of expanded Microsporidia; dark grey box encloses all members of the subclade including long‐branch Microsporidia. Green triangles (collapsed clades) represent OTUs from Neotropical soil samples only, ‘BM’ from Biomarks only, and blue from both.
