Twenty-five randomly selected fields of view were selected for analysis from each slide resulting in an index of fungal occurrence for each of 24 feces based on the total of 75 fields of view.

For microscopic studies, sections of dried basidiocarps were rehydrated in 3% KOH, subsequently stained in Congo red solution, Melzer's reagent and Cotton blue, and then observed under an Olympus BX 53 (Tokyo, Japan) light microscope (Nikon, Tokyo, Japan) at either 40, 100, 400, 600, and 1000 magnifications.

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.Ammonium hydroxide. For microscopical use a solution of between 5% – 10% seems to be the normal range, although 2% solutions are used by some mycologists. For macroscopical application stronger solutions are often used, these range from 10% to 75%, but 40% seems the most frequent used. Keeps for several years.
