Remarks

public notes
  Mycorrhizal systems regular to irregular monopodial-pinnate; mycorrhizal ends greenish yellow, with rusty-orange stains along elements; rhizomorphs at first dull greenish yellow and later rusty-orange; emanating hyphae with few to absent clamps, heavily to moderately encrusted; rhizomorph peripheral hyphae with golden-yellow to orange encrustations in mass; autofluorescence of mantle dull yellowish-olive and 1- to 2mm element tips dull orange, young rhizomorphs fluoresce moderately strong dull yellowish olive, while older ones fluoresce orange; in KOH within 1/2 min dull orange, in NH4OH conc within 1/2 min light orange, surrounding liquid pale yellow.
