Tubercularia vulgaris

Tubercularia vulgaris is a species of fungus in the family Nectriaceae. It is commonly known as the Pimpled Tarcrust due to its distinctive appearance. This fungus is found in various parts of the world, including North America and Europe, and is known for its ability to grow on dead or dying wood, particularly hardwoods.

Description[edit | edit source]

The Tubercularia vulgaris fungus is characterized by its bright orange or pinkish color and its pimple-like growths. These growths, or fruiting bodies, are small and round, typically measuring between 1 and 3 millimeters in diameter. The fruiting bodies are initially covered in a smooth, shiny skin, but this eventually ruptures to reveal a powdery mass of spores.

Habitat and Distribution[edit | edit source]

Tubercularia vulgaris is a saprophytic fungus, meaning it feeds on dead or decaying organic matter. It is most commonly found on dead or dying hardwood trees, particularly those in the Fagaceae family, which includes oaks and beeches. The fungus is widespread in North America and Europe, but has also been reported in other parts of the world.

Life Cycle[edit | edit source]

The life cycle of Tubercularia vulgaris begins when its spores are released from the fruiting bodies and carried by the wind to a suitable substrate. Once the spores land on a piece of dead or dying wood, they germinate and grow into a new fungus. The fungus then produces its own fruiting bodies, completing the life cycle.

Ecological Role[edit | edit source]

As a saprophytic fungus, Tubercularia vulgaris plays an important role in the ecosystem by helping to break down dead wood and return nutrients to the soil. It is also a source of food for various types of wildlife, including insects and small mammals.

Human Interaction[edit | edit source]

While Tubercularia vulgaris is not considered a significant threat to human health, it can cause decay in hardwood trees, which may be of concern to foresters and homeowners. However, the fungus is also valued by some people for its unique appearance and its role in the ecosystem.
