Assessment Notes


Fomitiporia bambusarum is a saprobic fungus reported growing on bamboo from southern Brazil, northern Argentina through the Brazilian Amazon into the mountains of Colombia. Due to its extensive geographic range the species is considered as Least Concern. Additionally, as it grows on bamboos, some of which are increasing in area due to disturbance of native forests, the species population is likely increasing in at least parts of its range.

Taxonomic notes

Fomitiporia bambusarum (Rick) Campos-Santana & Decock, 2015 (≡ Poria bambusarum Rick, 1937, =Phellinus rickianus J.E. Wright & J.R. Deschamps 1984, ≡ Phellinus bambusarum (Rick) M.J.Larsen, 1990) is a new combination proposed by Campos-Santana et al. (2015). Fomitiporia bambusarum belongs to a bamboo-specific species complex, which includes F. sanctichampagnatii, F. spinescens, F. uncinata and Phellinus garuhapensis.

Why suggested for a Global Red List Assessment?


Geographic range

In southern Brazil it is currently known from states of Rio Grande do Sul, Santa Catarina, Paraná and São Paulo, and in northern Brazil it is known from state of Acre. It also occurs in the Atlantic Forest of Argentina, and the Andean forest of Colombia. It has a large Extent of Occurrence (EOO: 3,066,353.803 km2), due to the great distance between localities in Colombia, Brazil and Argentina. From the map of subpopulations, the core of the species occurrence is located in southern Brazil.

Population and Trends

The species has a total of 42 records, all located in South America, with most of them from Brazil. The species was first recorded in 1932, in the state of Rio Grande do Sul, São Leopoldo. From 1932 to 2017 it was collected another 21 times in the same State. There are 18 records form other states in southern Brazil, plus one recorded occurrence in northern Brazil, one from Argentina (Coelho et al. 2009) and two from Colombia. The Argentinian locality and southern Brazil localities occur in one large subpopulation. The Colombian locality and the northern Brazil locality are considered as two distinct subpopulations due the large distance from each other. The known subpopulations were defined using the circular-buffer method with a scale of 1/10th maximum inter-point distance (Rivers et al. 2010). Additionally, the species is predicted to be widespread in the Brazilian Amazon region where there are bamboos. As it grows on bamboos, some of which are increasing in area due to disturbance of native forests, the species population is likely increasing in at least parts of its range. Because of the extensive area covered by the species, with it growing on bamboo from southern Brazil, northern Argentina through the Brazilian Amazon into the mountains of Colombia, the species is considered as Least Concern.

Habitat and Ecology

Fomitiporia bambusarum has only been reported growing on bamboos, occurring from the Atlantic Forest and Amazon in Brazil through to the Andean forests of Colombia.

Subtropical/Tropical Moist Lowland ForestSubtropical/Tropical Moist Montane Forest


Fomitiporia bambusarum is restricted to species of bamboo, and likely responds to changes in the occurrence and density of its host.
