Morphotype plG3 ("Glomus T7")
distribution in root cortex
outer cortex
auxiliary cells
absent
hyphae at entry point
prominent coiling, similar to plSc type
intraradical hyphae
all hyphae with prominent pegs or processes, thick 
(5 - 7 um diameter)
arbuscules
very rarely seen, scattered
vesicles
large (40 - 80 um), oval or sometimes irregularly shaped, intensively staining, often placed near the entry point
 

 

The status of this morphotype is uncertain: it might be just a special form of one of the better staining subtypes of the Acaulospora morphotype. The exact differentiation and morphotype assignment waits for a comparative study using single-taxa isolates.
