Assessment Notes


Craterellus peckii is a species known only from a single specimen collected on Long Island, New York. It is distinct from related taxa, and so the paucity of records suggest it could be a rare species. The fact that it has only been collected from a heavily urbanised area also raises concerns that the species could be under significant risk. However, without further surveys to ascertain its true, full distribution the possibility remains that the species could warrant a listing under any criterion from Least Concern to Critically Endangered. Therefore, C. peckii is assessed as Data Deficient.

Taxonomic notes

The type specimen of this species was originally placed within Craterellus caespitosus, but was re-described as a new species after the type material of that species was found to be Chlorociboria versiformis (see Petersen 1976).

Why suggested for a Global Red List Assessment?

Geographic range

Craterellus peckii appears to be known from a single collection made from Long Island, New York, USA (Petersen 1976).

Population and Trends

Without further information it is not possible to estimate the population size of this species. It is reportedly distinctive and caespitose in its fruiting, and so this could mean that this species is rare.

While its original collection was from an area that is now heavily urbanised, without a clearer indication of its full range it is not possible to ascertain whether this species may be in decline or not.

Population Trend: Uncertain

Habitat and Ecology

There is a paucity of information available for this species, with no habitats noted in the type description (see Petersen 1976).



While the type locality is heavily urbanised, without a clearer indication of the full range of this species it is not possible to estimate the degree of risk to its survival such a threat poses to Craterellus peckii.

Research needed

Further research is required on this species. It is reportedly distinctive, so focussed surveying both in its known range, and across a broader area should hopefully provide insight into whether this species is more widespread or if it could be truly very rare and at significant risk of extinction. If it is located, such surveying can provide additional information with regards to its habitat and ecological requirements and the threats it may face.
