Clavaria zollingeri Lév. - Violet Coral

Phylum: Basidiomycota - Class: Agaricomycetes - Order: Agarcales - Family: Clavariaceae

Clavaria zollingeri, Violet Coral

This beautiful violet coral-like fungus is found only very occasionally. The dichotomously branching fruitbodies can be up to 10cm tall and are initially violet but become dull grey-brown when old. It is an inedible species and is so rare that it should not be gathered except for important research.


Rare in Brtain and Ireland, most records are from Wales and England with just a few known sites in Northern Ireland and Scotland. This species is much more common in some eastern parts of North America.

Taxonomic history

Described in 1846 by French mycologist Joseph-Henri Léveillé (1796 - 1870), this fairy club fungus was given the scientific name Clavaria zollingeri which has been generally accepted as its basionym.

Synonyms of Clavaria zollingeri include Clavaria amethystina, Clavulina amethystina, and Clavaria lavandula Peck.


The specific epithet honours Swiss botanist Heinrich Zollinger (1818 - 1859), who specialised in the study of the genus Clavaria.

Identification Guide

Initially pale to deep violet, this very coral-like fungus can have rounded or moderately angular tips to its outer branches.

The whole fruitbody is 3 to 10cm tall and usually of similar width. The individual stems are typically 4 to 7mm across their major diameter.



Broadly ellipsoid to subglobose, smooth, 4-7 x 3-5µm.

Spore print


Other microscopic characters

The basidia are four spored, and there are no clamp connections; this differentiates Clavaria zollingeri from the macroscopically similar Clavulina amethystina, a European species which has two-spored basidia and clamp connections between hyphal sections.


Not distinctive.

Habitat & Ecological role

In broadleaf and coniferous woodland as well as in high quality (unimproved) grassland including old lawns, parks, churchyards and sheep-grazed pasture. Gait Barrows National Nature Reserve, Lancashire, England, and Rothiemurchas, near Aviemore in Scotland are two sites where this species is seen fairly frequently.


July to November in Britain and Ireland.


Rare in Britain and Ireland but fairly common in eastern parts of Northy America.

Similar species

Clavulinopsis umbrinella is a pinkish beige grassland species with a fused stem base that is paler than its branches.

Clavulina rugosa is smaller and white with one or just a few club-like branches with blunt tips.
