Assessment Status Notes

DD

Taxonomic notes

-previously known as Stereum burtianum Peck 1904
-other synonym: Podoscypha burtiana (Peck) S. Ito, 1955


Why suggested for a Global Red List Assessment?

This colourful and easily recognizable species was reported in nine countries but less than 24 times in 110 years.


Geographic range

-12 records in the Americas at 6 localities
-Belize in 2001
-Panama by Reid in 1966
-found in 1965 in Penambuco province of Brazil by Reid [1965, como Stereopsis butianum (Peck) D.A. Reid]
-found seven times in one location in Ohio, in a State park (1972 twice, 1973 thrice, 1978, 1980).
-found once in Tennessee in 1946
-only one station known in Québec (identified by Leif Ryvarden), Arboretum Morgan.

-found in India 1967
-China 2004
-found in 5 of 7 year in the same park in Korea
-reported in Japan (Ito 1955)
Asian reports have to be confirmed they belong to the same species to provide a better estimate of worldwide population.


Population and Trends

With 24 records worldwide in 110 years for an easy to identify species, we believe it is identified when collected. 
Found in 10 localities worldwide, but the number of localities may be up to 100 times higher, so we estimate is is to be found in 1000 localities. This estimate corresponds to 2000 genetically unique mycelia. The number of ramets are expected to be 10 times higher, so total number of individual worldwide is estimated to be 20000.

This estimate would usually qualify in a LC status but it is the result of a very high uncertainty about the number of localities due to its reported distribution in 9 countries in the Americas and in Asia.  We propose the status DD to promote research and surveys to reduce uncertainty and provide better estimates of its population.

If Asian reports are shown to be a different species, it would greatly affect the estimated population.  For example if only estimating the American population based on its known 6 locations in 5 countries, then population would be estimated at 6000.  Surveys of its mossy habitat by local mycology club would greatly reduced the 100 factor used to estimate its number of locations.

Population Trend: Uncertain


Habitat and Ecology

On damp soil with mosses in temperate forest.

Temperate ForestBogs, Marshes, Swamps, Fens, Peatlands [generally over 8 ha]

Threats

Nitrogen deposition could greatly affect its mossy habitat and lead to decline.  Reference on effect of nitrogen deposition of mosses and estimated decline.

Housing & urban areas

Conservation Actions

Sites where this species is found could be proposed for protection.

Awareness & communications

Research needed

Asian reports need to be confirmed as we may be facing a complexe of species.

In northeastern North America, where this species is found, there are numerous groups of amateur mycologists. Members of these groups can be recruited and instructed where to find and how to identify this species so they can target this species during forays. Data from amateur mycologists can be critical to define its population size, distribution and trends.

Surveys of its mossy habitat by local mycology club would greatly reduced the 100 factor used to estimate its number of locations.
