Unsure what countries to select in the “Country occurrence” section
Sceptrulum inflatum is a corticioid species originally described as potentially rare. There are very few records of this species and no detailed recent occurrences and little information is available. It’s current distribution is therefore not clear, but potentially large. Further research is needed to define distribution limits and estimate population size. Since this species could apply to both threatened and Least Concern categories, it is assessed as Data Deficient (DD).
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 is also considered a synonym to this species (Species Fungorum 2023). Karasiński noted that descriptions of both species included only small morphological differences that could be attributed to intraspecific variability, but observed that the geographical separation between their type locations (Jamaica and Seychelles) could support the possibility that they are distinct species.
So far, no phylogenetic studies have been done on this species.
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.
There are at most 4 records available for S. inflatum, if specimens collected in 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
Corticioid species, found growing on very rotten wood (Burt, 1925).
Unknown.
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.
