(10.7) 11.6 - 13.2 (13.7) × (6.4) 7 - 8 (8.4) µm
Q = (1.5) 1.54 - 1.7 (1.9) ; N = 20
Me = 12.3 × 7.5 µm ; Qe = 1.6

Different references give different spore size ranges for M. lagenaria, and if anything our spores seem small by comparison.   Our collection would appear to constitute a range extension for M. lagenaria, if it can indeed be said to be that sp..  Is there another possibility?

Any and all help is greatly appreciated.  Additional micrographs available upon request.
