Photograph of the type specimen of Amanita flavoconia made by George Atkinson in 1902. Note that the yellow caps and stems of this mushroom appear quite dark in this black and white photograph. This is most likely the result of Atkinson using an orthochromatic glass plate negative to make the image. Orthochromatic film is mostly sensitive to blue light and much less sensitive to green, yellow, and red wavelengths. This makes objects that are green, yellow, or red appear darker in the photograph than one would expect them to be. Todays black and white films are panchromatic, having similar sensitivities to all wavelengths of visible light.

The article in the Journal of Mycology in which Atkinson described this new species is pictured below.
