Nothocorticium patagonicum is a corticioid species growing on bark of living Nothofagus betuloides and N. pumilio trees but also on decayed wood of the same species. When growing on bark basidiomes are small, orbicular to oblong, peach-colored (orage-pink, to pink reddish). Margin with profuse, white hyphal strands. When growing on decayed wood basidiomes are widely effuse and bigger. Subiculum cottony and white, contrasting with the hymenial surface. Microscopically is characterized by the large, 2-sterigmate basidia, large basidiospores with a blunt apiculus and predominately thick-walled, narrow generative hyphae that culminate in the hymenium as simple or branched, strongly encrusted hyphidia.
Why suggested for a Global Red List Assessment?
Nothocorticium patagonicum is a very particular corticioid fungi growing on Nothofagus spp. in Patagonia Argentina. The species has some unusual morphological and ecological features that make it of special interest for science. Eventhough it is not seriously threatened in not a common species and deserves to be included in the list as a Least Concern (LC)
Nothofagus dombeyi and Nothofagus pumilio forests of Patagonisn Andes forests.
Population and Trends
Not rare but not a common species.
Population Trend: Presumably stable
Population Trend: Stable
Habitat and Ecology
The species has an unusual ecology because it grows on bark of living Nothofagus trees but also on much decayed wood. The species that grows on living bark are usually restricted exclusively to that sustrate (eg. Dendrothele species), but it is not the case of N. patagonicum which can grows on a very different substrate as the much decayed wood.
No major threats. Only habitat disturbance and reduction by human impacts (mostly logging and wood harvesting and fire).
