Assessment Notes

Justification

Craterellus calicornucopioides is widespread and common. Decline is limited, mostly from habitat loss due to Sudden Oak Death killing the preferred host tree, Tanaok.

Due to the total Area of Occurrence, and limited overall population decline, it is assessed as Least Concern.


Taxonomic notes

Craterellus calicornucopioides was long referred to by the European species, C. cornucopioides (Thiers1985, Arora 1986).

The distinct western North American entity was described from a Type collection made in Mendocino County, California, USA (Frank 2015).


Why suggested for a Global Red List Assessment?

Chanterelle project


Geographic range

Craterellus calicornucopioides is known from central California, USA, north into Washington state. This species is most common in Tanoak (Notholithocarpus densiflorus) dominated forests in northern California and southwest Oregon, but occasional in live oak woodlands to the south, and mostly with Oregon White Oak (Quercus garryana) to the north.


Population and Trends

Population of this species is widespread, occurring over a large expanse of western USA. Locally, it is a very abundant species. Most of the population is currently stable, but decline of Tanoak due to the introduced pathogen Sudden Oak Death (Phytophthora ramorum) is worrisome.

Population Trend: Stable


Habitat and Ecology

Craterellus calicornucopioides is ectomycorrhizal with hardwoods; especially Tanoak (Notholithocarpus densiflorus), Coast Live Oak (Quercus agrifolia) and Oregon White Oak (Q. garryana). Also reported with Vaccinium and/or Douglas-fir (Pseudotsuga menziesii) in the northern portion of its range (Frank 2015). Very common in the mixed evergreen forests of northern California, occasional elsewhere, fruiting from early winter into spring.

Temperate Forest

Threats

Overall, this species appears stable, with local populations under threat due to the introduced pathogen Sudden Oak Death (Phytophthora ramorum) killing large swaths of Tanoak.

Named species

Conservation Actions

Limit the spread of Sudden Oak Death in northern California forests.


Research needed

No specific research is needed with regards to this species.


Use and Trade

Craterellus calicornucopioides is a highly desired edible species, and is collected by hobbyist foragers and commercial pickers. However, no decline has been recorded due to current harvest practices.
