Mycorrhizal systems irregularly monopodial-pyramidal; mycorrhizal ends at most slightly sinuous, white-grey or slightly reddish (mantle), brown due to root colour, older parts brown due to root colour; inner mantle layers in plan view with cells possessing folded walls; emanating hyphae with stripe-like thickened walls. |
