A speckling of semi-dry cobalt crust growing on oak rot. Also called "Velvet Blue Spread," this fungus, when exposed to high temperatures or other lab-controlled stimulants, produces an antibiotic that can be used to treat many common types of infections.
Oak rot found in the leaf litter of a mixed deciduous forest residential area. This type of crust fungus is fairly global, at least in the warmer climates. They distribute their pores in the autumn and usually dry out in colder weather only to spring back to life when a more favorable warmth and humidity come around!
