Remarks

public notes
  Mcorrhizal systems irregularly monopodial-pyramidal; mycorrhizal ends slightly bent, sometimes slightly beaded, sometimes tapering, grey or slightly ochre, older parts with larger dark greyish patches, when air displaced by water; septa of laticifers infrequent; outer mantle cells can be regarded as cystidia; Hartig net in plan view a weakly ramified palmetti- type; tannin cells in cross-section sometimes also cylindric, cortical cells in cross-section mostly tangentially-oval; autofluorescence of mantle in section with UV-filter bluish and laticifers more intensely, with blue-filter greenish and laticifers more intensely, with green-filter slightly reddish and laticifers more intensely; mantle in sulfo-vanillin greenish-pink with well distinguishable laticifers and latex greyish olive-green, with guaiac blue, with FeSO4 ochre, in lactic acid slightly ochre tint destains slightly, in brillant-cresyl-blue blue, in ethanol slightly ochre tint destains slightly, in phenol mantle darkens slightly, in acid fuchsin slightly pink; nuclei lying often very close.
