Assessment Status Notes

Taxonomic notes

Lamproderma disseminatum described by Charles Meylan in 1970.
This is rare nivicolous species in small colonies, found at high altitude on debarked dead wood (Pinus cembra) on the ground. It’s determination is from specific dark brown nodulose or spiny capillitium.


Why suggested for a Global Red List Assessment?

Lamproderma disseminatum is a very rare species of nivicolous myxomycetes, which is directly affected by change of climate with, as consequence, a diminution of weeks during the substrate is covered by snow. The small colonies of this species found at high altitude on debarked dead wood (Pinus cembra) on the ground.
During the workshop at Ekenäs in Feb 2015, its present preliminary status was found to be DD.


Geographic range

ASIA: Russia (Tumen region)
EUROPE: Austria, France, Switzerland.
NORTH AMERICA: USA (California, Washington).


Population and Trends

In total 12 records from 5 locality are known.
How many potential localities on a global/european scale? The substratum (Pinus cembra) is very common, but it is not usual substratum for others nivicolous species. May be this the reason why Lamproderma disseminatum is so rare species. Most of others nivicolous spesies from genus Lamproderma usualy are common.

Population Trend: Uncertain


Habitat and Ecology

This is rare nivicolous species in small colonies, found at high altitude on debarked dead wood (Pinus cembra) on the ground.
The nivicolous species of myxomycetes are organisms that belong to different genera sharing the same environmental conditions in their life cycle. These conditions can be found in the mountains, where, on the highest summits, the snow cover remains intact during the coldest months. In spring, with the increase of temperature, when thaw starts slowly, the sudden change from cold to warm favours the germination of the spores that have remained covered under the snow. Subsequently, the formation of plasmodia and fructifications over the vegetation that had remained under the snow occurs.


Threats

Probably threatened by climate change, as all nivicolous spesies. Nivicolous Myxomycetes is directly affected by change of climate with, as consequence, a diminution of weeks during the substrate is covered by snow.
Lamproderma disseminatum was founding in France (Savoie, Bourg-Saint-Maurice, Arc 2000), but in 2003 this locality destroed with build sky stations. Threats exploitation, loss of suitable microhabitat quality. NT D1.
Most appropriate evaluation may be DD (data deficient), that indicates that more data is needed.
