Species Profile
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.
Key Facts
Habitat & Distribution
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. A 2006 study used...
