Assessment Notes

Unsure what countries to select in the “Country occurrence” section


Sceptrulum inflatum may be a potentially rare species, but there are very little records and information available and its distribution is not yet clear. Further research is needed to define distribution limits and estimate population size, so for now the species is assessed as Data Deficient (DD).

Taxonomic notes

Only species in the monotypic genus Sceptrulum. It was initially described as Peniophora inflata but can be distinguished from species in similar genera by its microscopic characteristics (Karasiński, 2014). Palifer seychellensis was also considered a synonym to this species (Species Fungorum 2023), but Karasiński noted that there were small morphological differences between the two. Given the geographical distance between both collections (Jamaica and Seychelles), further research is needed to confirm they are conspecific.
So far, no phylogenetic studies have been done on this species.

Why suggested for a Global Red List Assessment?

Geographic range

The distribution limits of S. inflatum are not clear. GBIF.org (2023) includes records of the original occurrence of S. inflatum in its type location in Jamaica and one occurrence in Massachusetts, United States, as well as one further record for the genus Sceptrulum in Brazil (not identified to species level). Maekawa (2021) also included S. inflatum in a list of corticioid fungi found in Japan and, if Palifer seychellensis is confirmed as a synonym to this species, one more record exists in the Seychelles.

Population and Trends

There are at most 5 records available for S. inflatum, if specimens collected from Brazil, Japan and Seychelles are confirmed as the same species. Moreover, collections from Jamaica and the United States were made in 1908 and 1926, respectively, and no further records have been made since in these locations. In the description of the species Burt (1925) considered S.inflatum to be probably rare, but it may also be under sampled given its inconspicuous fruitbodies. More research into the distribution of the species and search efforts are needed to estimate population size for this species.

Population Trend: Uncertain

Habitat and Ecology

Corticioid species, found growing on very rotten wood (Burt, 1925).



Conservation Actions

Research needed

Further research is needed to confirm if all specimens correspond to a single species given their geographical difference, and determine distribution, habitat preference and estimate population size.
