the bracket fungus forests use as a canvas
- Size
- Width: 10–30 cm
- Lifespan
- 1 years
- Diet
- Saprotrophic and parasitic: feeds on dead and living wood of native and introduced trees. Grows on trunks of living trees as a parasite and on dead logs as a saprotroph.
- Habitat
- Grows on trunks of living and dead trees forming large woody brown brackets with a white underside. When scratched the white pore surface turns brown permanently allowing artists to draw.
- Range
- Throughout North and South Islands on trunks of native and introduced trees. Most common in lowland forests with abundant mature trees. Found worldwide.
- Endemism
- Native
- Main Threats
- None significant. Localised threats include removal of old decaying trees from urban parks and forests and collection by artists who use the fungus as a canvas for drawings.
- Population
- A large woody bracket fungus on trunks of living and dead trees. The white underside turns brown permanently when scratched allowing artists to draw pictures. The fruiting body can persist for years.
- Conservation Status
- Not Threatened
It serves as the living canvas of the forest. This is a fungus designed to be drawn on. The Artist's Conk is defined by its interactive surface. The fruiting body is a large, woody bracket. It spans ten to thirty centimetres across. The top is brown to greyish-brown. It is rough and cracked like old leather. The underside is white. It is covered in a layer of tiny pores. These are invisible to the naked eye. This is the canvas. A fungus that doubles as a sketchbook. The duality is striking.
When the white pore surface is scratched, it changes. Use a sharp stick or a fingernail. The tissue turns brown permanently. The damaged area oxidises and darkens. Pictures can be drawn. Words can be written. Intricate designs can be created. The fungus becomes a living record. It captures the hands that have passed by. The name 'Artist's Conk' is well-earned. The functionality is immediate. The result is lasting.
Biologically, the Artist's Conk is both a parasite and a saprotroph. It grows on the trunks of living trees. It enters through wounds in the bark. Then it slowly rots the heartwood from the inside out. It can take decades to kill a mature tree. But eventually, the tree will fall. The fungus continues to feed on the dead wood. It persists for years. It adds a new layer of pores each season. The growth is incremental. The decay is steady.
The Artist's Conk is not edible. It is tough and woody. It has no culinary value. But its beauty lies in its utility. It offers itself as a canvas for human creativity. The interaction is unique. The medium is organic. The art is ephemeral only in the sense that the host decays. The drawing remains until the fungus crumbles.
To find an Artist's Conk is to find a blank canvas in the middle of the forest. The forest is quiet. The conk grows on a tree trunk. It is brown and cracked above. It is white and pore-covered below. A stick scratches the white surface. Brown lines appear. The fungus does not know it is a canvas. It does not know it is an artist's tool. It simply exists on the decaying wood. It breaks down the lignin. It releases the nutrients. It carries on.
The natural world is not separate from art. The forest can be a gallery. The Artist's Conk is proof. It bridges the gap between biology and expression. It allows for mark-making on a living surface. The oxidation process ensures permanence. The tree provides the structure. The fungus provides the page. The human provides the intent. The collaboration is accidental but effective. It carries on.
