Microscopic features, measurements and drawings were made from slide preparations stained with Cotton Blue or Melzer's reagent. Spores were measured from sections cut from the tubes (Cui et al. 2008). In presenting the variation in the size of the spores, 5% of measurements were excluded from each end of the range, and are given in parentheses.

Melzer's Reagent. Melzer's Reagent can be used to test spores for amyloid, nonamyloid, and dextrinoid.
