Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/265979758/266017972

Justification

Phaeoblastophora peckii corresponds to an asexual form and it is not clear whether a corresponding sexual morph is known. It has only been recorded twice in the last 50 years, in the USA and China. Even though it may have a wide distribution and range of suitable habitats, it is difficult to establish current distribution and population size without more recent records. Therefore the species is assessed as Data Deficient (DD).

Taxonomic notes

Partridge and Morgan-Jones (2002) established Phaeoblastophora peckii in place of Alysidium resinae var. microsporum, Torulosa peckii and T. ramosa Peck (nom. illegit.) based on its morphological characteristics. However, Species Fungorum (2023) does not list A. resinae var. microsporum as a synonym of P. peckii, but rather of A. resinae. Since the only other previous Phaeoblastophora species (P. resinae) is currently accepted as A. resinae, Phaeoblastophora is now a monotypic genus according to Species Fungorum (2023). It is not clear if a sexual morph form for this species is known.

Geographic range

This species is found in New York, USA and more recently in Hainan, China (Wang et al. 2016).

Population and Trends

The establishment of Phaeoblastophora peckii was based on records for Torulosa ramosa prior to 1879. In the last 50 years it has only been recorded in 1978 (Partridge and Morgan-Jones 2002) and more recently in 2014 in China (Wang et al. 2016). Its apparent wide distribution suggests there may be a large number of unknown sites, but without more recent observations it is not possible to establish the current population size.

Population Trend: Unknown

Habitat and Ecology

This name corresponds to an asexual form and it is not clear whether a corresponding sexual morph is known. It has been reported as growing on dead wood. It has been found in both the USA and China, suggesting that it may have different suitable habitats.

Threats

Threats to this species are unknown.

Conservation Actions

Research into substrate preferences and further sampling is needed to establish population size and distribution limits. Taxonomic revision is also important to confirm its placement in a monotypic genus and clarify which records should be attributed to this species.
