  1. *Number of measured spores ranged between 50 and 60 spore. The difference in spore lengths or widths between fresh and stained spores are, in general, significant (t test; significant at 5 or 1% level). Data followed by the same letter within column do not differ significantly at 1% level; Duncan’s multiple range test
  2. **Standard deviation of the mean (SD) and standard error (SE)
