Remarks

public notes
  Mycorrhizal ends dark brown to blackish; cell walls of emanating hyphae dark brown; inner mantle layers in plan view with yellowish brown walls; cystidia slightly clavate at tip, thick-walled at the base, somewhat thick-walled towards the apex, there walls ca. 0.3 um thick, cystidia sometimes simple septate in distal part.
