Attention: Order should be Agaricales (according to species Fungorum and phylogenetic data)
L. incarnatum is a freshwater fungal species that grows on floating hardwood. It is not commonly recorded but appears to have a very wide distribution and is likely undersampled. Population size is estimated at 42000 mature individuals with no evidence of population decline, so the species is assessed as Least Concern (LC).
L. incarnatum is so far the only accepted species in the monotypic genus Limnoperdon and family Limnoperdaceae, established based on its distinct morphological characteristics (Escobar et al., 1976). It has since been placed within Agaricales using phylogenetic data (Matheny et al., 2006). A more recent study reported the presence of a second Limnoperdon species in the River Nile in Egypt (Abdel-Aziz, 2016), but it has not yet been described.
Even though its distribution limits are not well defined, L. incarnatum appears to have a very wide distribution. So far it has been recorded in United States, Canada, Japan, South Africa and Austria (Michaelides et al., 1982; Webster et al., 1993; GBIF.org, 2023).
L. incarnatum has only been recorded in a few sites (around 13), but the total number of locations is likely much larger considering the very inconspicuous fruitbodies (small globose/subglobose basidiocarps, 1mm or less in diameter) and wide distribution and area of potential habitat. By applying a large multiplier for unknown sites (x1000), and following guidelines by Dahlberg and Mueller (2011), population size is estimated at 42000 mature individuals.
Population Trend: Uncertain
Grows on floating hardwood in freshwater habitats, such as marshes, ponds and margins of rivers and streams but also in rice paddy fields and Brackish water. Most observations of its fruitbodies have been made in laboratory conditions on previously submerged twigs. It has been recorded growing on Acer saccharum and Fagus grandifolia but did not grow on Pinus strobus under similar conditions. (Michaelides et al., 1982; Webster et al., 1993)
No threats have been identified for this species.
