Coniochaeta tetraspora

Coniochaeta tetraspora is a species of fungus in the family Coniochaetaceae. It was first isolated from forest soil in Queensland, Australia, and has since been recorded from the Galápagos Islands, Spain, and California. The species exhibits a distinctive pattern of ascospore development: eight spores initially form within each spore sac, but four consistently abort, leaving only four to mature. In culture, colonies are thin and whitish, later becoming pinkish as asexual spores accumulate, and the dark, pear-shaped fruiting bodies bear short spiny hairs. The fungus is self-fertile, meaning a single spore can give rise to a colony capable of completing its sexual cycle without a mating partner....read more on Wikipedia.
