Diachea leucopoda #3

Diachea leucopoda (Witpootglinsterkopje (BE) / White-footed Slime (EN)) is a species of slime mold.
More info and general view: see 2 previous posts.

Only very recently (sept. 2010) a scientific article was published on how the different color bands of this species are formed. The color does not depend on pigments! The researchers found that the species' peridium - the protective layer that encloses the mass of spores - is basically a corrugated layer of a transparent (!) material, which produces a multicolored pointillistic effect, characteristic of this species due to the result of an interference effect. This is called "structural color" and it is a property found in many plant and animal species, as well as some minerals, which have iridescence due to interference effects of light. The effect is depending on the angle of the beholder...

Abstract and full version of this article (in english) are available on :
Marina Inchaussandague, Diana Skigin, Cecilia Carmaran, and Sonia Rosenfeldt, "Structural color in Myxomycetes," Opt. Express 18, 16055-16063 (2010)

Image taken with 150mm macro + 2x Extender + 1.4x Extender, natural sunlight. (An individual sporangium is max. 0.6mm in diameter and between 1 and 1.5mm in hight.)
