Overview

Dendrocollybia is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species Dendrocollybia racemosa, commonly known as the branched collybia or the branched shanklet.

The Branched Shanklet faces severe population declines primarily due to habitat loss from deforestation and forest degradation in its limited range. As a saprobic fungus dependent on specific dead wood substrates in old-growth forests, it is particularly vulnerable to logging activities and forest management practices that remove decaying organic matter.

Threat summary

Habitat

Russula crassotunicata has been verified as a host for Dendrocollybia.

Dendrocollybia racemosa is a saprobic species, meaning it derives nutrients by breaking down dead or dying tissue. Its fruit bodies grow on the well-decayed remains of agarics, often suspected to be Lactarius or Russula, although the hosts' identities are often unclear due to an advanced state of decay.

Frequently asked questions

Why is Branched Shanklet classified as Endangered?
Branched Shanklet is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The Branched Shanklet faces severe population declines primarily due to habitat loss from deforestation and forest degradation in its limited range. As a saprobic fungus dependent on specific dead wood substrates in old-growth forests, it is particularly vulnerable to logging activities and forest management practices that remove decaying organic matter.
Where does Branched Shanklet live?
Branched Shanklet occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Branched Shanklet?
The main threats to Branched Shanklet are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
