(21.1304° -99.4567° 1800m)
No herbarium specimen

Notes: Growing from a chunk of decayed hardwood – either Quercus or Liquidambar.

Spores and basidia turning black in melzers. Spores smooth and ellipsoid, hyaline in KOH, with a conspicuous hilar appendage. Basidia sometimes with granular contents. Cheilocystidia present and hyaline in both KOH and melzers. Cheilocystidia sometimes with refractive contents that turn black in melzers.
