  • Getting more from your spore data - Graphical and simple arithmetic methods of analyzing your spore data, comparing the spore size and shape of multiple taxa, evaluating the reliability of spore measurements from a single specimen (without knowledge of the taxon to which it belongs), etc.

    • Record your spore measurements in an upside down bargraph. - "And I benefit from this exactly how?" (here)
      • Understanding measurement accuracy (t.b.d.)

      • Rounding decimal values (here)

      • Writing a range for length, width, Q, etc. - Use a standard method that supports the use of sporographs.  (here)

      • Mean, median, and mode - Remember these from high school algrebra? If you are old enough, you were probably never taught the second and third unless you took Statistics. Even if you do recognize all three terms and remember their meanings, have you used them to analyze spore measurements from a single specimen? from many specimens? (t.b.d.)
    • Getting started with sporographs - basics of learning to draw one.

    • Introduction to sporographs through Algebra 1 for a secondary school science and engineering honors group: PDFs of slides, workbooks based on actually data on spores from Amanita specimens, etc.  A number of workbooks based on different datasets for different species of Amanita are available, each intended for a group of 1 to 4 students.  (Prepared for Manalapan High School (Freehold Regional School District), Manalapan, New Jersey, U.S.A. First presentation 27 April 2010.)  (slides  workbook no. 1  workbook no. 2  workbook no. 3  workbook no. 4  workbook no. 5  workbook no. 6  workbook no. 7  workbook no. 8  workbook no. 9)

    • Using a sporograph (part I, data comparison)
      Using a sporograph to compare sets of spore data

      • from two or more specimens  (t.b.d.)

      • from a specimen to spore data described for a taxon  (t.b.d.)

      • from two or more descriptions of distinct taxa  (t.b.d.)
    • Using a sporograph (part 2, data interpretation)
      • "Giant" spores.  What? Why? When? (here)

      • Depressed spore values.  Why? (t.b.d.)
    • Forms for recording data

      • RET's form for notes on fresh material, for use whenever collecting Amanita specimens.

        • Blank form.  It is recommended that only the first four pages of this form be used, two pages printed in landscape mode on each side of a single sheet of letter paper.
