Observation 8667: Amanita longipes Bas ex Tulloss & Dav. T. Jenkins
When: 2008-07-23

spores seem odd for this species…

Did the kidney shaped spores come from one of the yellowing specimens? Usually, this species has straight-sided narrow spores with an average Q of around 2.2+/-.

Sometimes the yellowing syndrome seems to contribute to irregular or stunted spore shape/size.
