- Lifespan
- Annual
- Diet
- Saprotrophic, decomposing dead wood of hardwood trees to release nutrients back into the forest soil.
- Habitat

- Range
- Found in native and urban forests throughout New Zealand, particularly on hardwood trees.
- Endemism
- Introduced
- Main Threats
- Habitat loss from logging of old, decaying hardwood trees and removal in urban areas as perceived pests.
- Population
- Uncommon but widespread in suitable habitats throughout New Zealand, particularly in autumn and winter.
- Conservation Status

- Te Ao Māori
- Māori names for specific hericium species are not recorded in standard dictionaries. In a kaitiakitanga framework, these fungi represent the hidden industry of the forest. Their cascading form signals the active breakdown of wood. Protecting them means preserving the integrity of the forest ecosystem and the unseen processes that sustain it. The beard is not decoration. It is function.
It hangs like a beard. The Comb Tooth does not have a cap. It has a mass of long, white spines that dangle from a central base. These spines are soft to the touch, resembling wet hair or icicles. They grow downwards, reaching for the ground. The base is attached to the wood, often hidden behind the cascade of teeth. It is a striking fungus, visible from a distance. But do not touch it. The spines are fragile. They break easily, leaving a bare patch on the fruiting body. This damage is permanent. The fungus does not repair itself. It grows around the wound.
The Comb Tooth is found throughout New Zealand, from the northern forests to the southern beech lands. It is not common. It appears singly or in small clusters on dead or dying hardwood trees. It fruits in autumn and winter, often after heavy rain. It is not picky about its host, thriving on both native and introduced species. Its presence is a sign of decay in progress. Where it grows, lignin is being broken down. Nutrients are being released. The cycle continues.
This fungus is saprotrophic. It does not form mycorrhizal relationships with trees. Instead, it feeds on decaying organic matter, breaking down dead wood. In doing so, it releases nutrients back into the soil. It is a recycler, working in the shadows of the forest. Without it, the debris would pile up. The forest floor would stagnate. The Comb Tooth is efficient. It consumes what is dead to feed what is living. Its white colour is a signal of activity, a sign that decay is in progress.
The spines are the reproductive structure. They produce spores that are carried by the wind to new hosts. The fungus does not rush. It waits for the wood to die, then consumes it slowly, methodically. The flesh is white and firm. It smells faintly of earth, nothing more. Unlike the Garlic Parachute, it has no distinct scent. Its defence is structure, not chemistry.
Threats are significant. The species is sensitive to changes in forest structure. Logging removes the old, diseased trees that the fungus depends on. Without these hosts, the population declines. The fungi wait for the forest to mature. They do not rush. It carries on. In urban areas, it is often removed as a pest, mistaken for a sign of tree health rather than decay. This misunderstanding leads to its destruction. It carries on.
