Description of mycorrhizal morphotypes
| Morphotype | Description | Identification | Best BLAST match(es) (% similarity) |
|---|---|---|---|
| Suilloid | Dichotomously branched; coralloid to subtuberculate and clusters; white, pink, or light brown; thick mantle; abundant; loose or fluffy extramatrical mycelium; white to brown strands present, ectomycorrhizal | Suillus luteusa,b | AJ272416: Suillus luteus (100) |
