the species was only found in in a humid spot of the National Park “Los Alerces” on the Argentinean slope of the Andes. It belongs to an ectomycorrizal genus. However, no DNA matches are found from root tips or enviromental sequencing, suggesting that it is not well represented in the root tips as are most Tomentella species from Patagonia. Los Alerces National Park lost a great part of its native surface due to fires, wich threatens its biodiversity. Farming and cattle are allowed for families inhabiting this park, but the animal load disturbs the renewals of Nothofagus and other tree species and also removes and disturbs the herbaceous level of vegetation as well as the fallen branches and other lignocelulosic materials where this and other species produce their sporomes.
Chubut province in central Patagonia. Until now, restricted to Los Alerces National Park, and only found in a humid spot of this natural reserve.
No soot tip or soil sequences are available in the database other than the original findings of the description. For this reason we assume that this species is limited to humid patches Nothofagus dombeyi forests. Since this tree species is limited to low altitudes in the Andes mountains the substrate consisting in woody debris is being affected by the heavy animal load of these landscapes. We assign a population number of 10000 considering that it might be present in similar spots in other areas.
Population Trend: Uncertain
Basidiomes are produced on woody debries. The nutritional mode is supposed to be ectomycorrhizal, since no saprotrophic species are reported in the genus Tomentella ss stricto (exc. odontia ss Tedersoo et al 2014)
Cows and other farm animals constitute the major disturbance for the Nothofagus dombeyi forests, since these trees grow in lower altitudes than other members of the family. Cattle is not limited in most of the preserved areas in Patagonia and, as a consequence, the fungal species colonizing or reproducing on woody debris on the soil surface lose their potential substrate. Fire eventsz were more frequent in the last years due to drought, and this reduce considerably the habitat.
The confirmation of the EM nutritional mode is needed as well as the real distribution.
