Assessment Notes
Taxonomic notes
Cinereomyces lindbladii strongly resembles Sidera lenis. Under the microscope, the clearest difference is in the skeletal hyphae: these have a very distinct lumen covering at least half of the hyphal width in Cinereomyces, and hyphae are rather irregular in outline. The hyphae are also much wider, commonly over 5 µm in diameter as opposed to under 3–4 µm in dimitic Sidera species. They also dissolve in KOH unlike those of Sidera species. Spores of C. lindbladii are on average only slightly curved and a bit larger than in any species of Sidera. Large crystals are found in trama, part of them in the shape of irregular rosettes (Miettinen & Larsson 2011).
Why suggested for a Global Red List Assessment?
Geographic range
It is a common species and can be found in many countries around the world. Most reports are in Sweden and Norway.
Population and Trends
There are about 10.000 records in many countries.
Population Trend: Uncertain
Habitat and Ecology
In Brazil, the species is found in Atlantic Forest and Amazonia.
Threats
In Brazil, the species is present in pluvial forest domain. However, the Amazon has currently the highest rates of deforestation in the last decades and the Atlantic Forest is already a hotspot.
Conservation Actions
Some records in Brazil are in unprotected areas.
Research needed
Other areas should be studied in order to assess the distribution of this species in Neotropical regions.
Use and Trade
None.
