Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/265983885/266020709

Justification

Spiniger curiosus has only been documented in the original description of the species in 1969, under the name Paullicorticium curiosum and has not been recorded since. It potentially represents the asexual form of another species. Mutatoderma pupulneum has been suggested but this has not yet been confirmed. A taxonomic review of this taxon is needed and the species is assessed as Data Deficient (DD).

Taxonomic notes

Spiniger curiosus is a currently accepted name in Species Fungorum (2023) and only remaining specie in the genus. However, Donk (1971) concluded it was the conidial state of a Hyphoderma species, possibly Hyphoderma populneum (now Mutatoderma pupulneum).

Geographic range

This species was recorded from Siberia (Parmasto 1969).

Population and Trends

This species has only been documented in its original description (under the name Paullicorticium curiosum). It is not possible to estimate the population size.

Population Trend: Unknown


Habitat and Ecology

It was found growing on Populus tremula fallen wood.

Threats

This species' threats are unknown.

Conservation Actions

Given that Spiniger curiosus potentially corresponds to an asexual form of another species, a review of its taxonomic placement is needed.
