Sordaria macrospora

Sordaria macrospora is a species of coprophilous (dung-colonizing) fungus.^[1] It is one of several fungal model organisms in biology, e.g. the model of fruiting body development in Ascomycetes. It is a homothallic, self-fertile organism.^[2]

Ascospores issued from a diploid heterozygous at the spore-color locus, segregate as yellow and black. Different colors patterns reflect DNA recombination events during meiotic prophase. Lighter colors are due to incomplete maturation.
