Remarks

public notes
  Mycorrhizal systems irregularly monopodial; mycorrhizal ends at most slightly bent, somtimes inflated at tip, distinctly yellow-orange-brown or vivid yellow-orange to dark orange, very tips dark orange to red-brwon, older parts dirty-brown; middle and inner mantle layers in plan view densely plectenchymatous; in cross-section Hartig net 1-3 cortical cell layers deep; mantle in sulfo-vanillin with dark violet droplets in laticifers.
