Chlorociboria aeruginascens

Common Names: Green elfcup, green wood cup
Category: Fungi
Sub-category: Cup Fungus

Although the actual fruit bodies are infrequently seen, the green staining of wood caused by the fungus is more prevalent. This species has apothecia (cup-shaped ascocarps) that are usually attached laterally, often less than 0.5 cm in diameter, collapsing laterally and becoming rolled inwards when dry. The outer tissue layer of the apothecium, known as the ectal excipulum, has a delicate tomentose surface composed of hair-like, straight or sometimes coiled, smooth hyphae. The stipe is typically less than 3 mm long, with a central or eccentric attachment to the apothecia. Apothecia grow on bark-free wood, especially oak, part of which at least is stained greenish by the mycelium.

Saprobic, found growing on decaying hardwoods.
