Assessment Notes

Taxonomic notes

It is part of the Cladosporium cladosporioides complex and morphologically very similar with C. exile and C. scabrellum, differing by the size of the conidiophore and conidia. Similar to C. cladosporioides and C. pseudocladosporioides, C. perangustum could probably also be a species complex, since there are more phylogenetic differences in that clade for both ACT and TEF than between some of the other more closely related species that we recognise as distinct species. However, the morphology of all isolates is quite uniform and the clade phylogenetically highly supported (Bensch et al., 2010).

Why suggested for a Global Red List Assessment?

Cladosporium perangustum has few records in the world, most of the time occurring as an endophyte and phytopathogen. In Brazil, there are records of the species in the Atlantic Forest and in the Amazon rainforest. I suggest including it in the near threatened category.

Geographic range

According to GBIF the species has 27 occurrences in 7 countries. In Brazil the species occurs in the Amazon Forest and the Atlantic Forest.

Population and Trends

There are about 27 records of the species in the world, of which nine (34%) are in the United States of America. Despite its global distribution, the species appears to be little common.
In Brazil Cladosporium perangustum occurs in the Atlantic Forest and the Amazon Forest, two hotspots of biodeversity, but extremely threatened.

Habitat and Ecology

Worldwide distribution, but found mainly in the United States of America and Australia.

In general, the specie occurs in forest areas, some of which are threatened by deforestation and urbanization, such as the Atlantic Forest and the Amazon Forest in Brazil.

Conservation Actions

Most records of Cladosporium perangustum in Brazil are in areas of environmental protection, but are also found in agricultural areas.

Research needed

According to Bensch et al. (2010) probably Cladosporium perangustum could be a species complex, because there are more phylogenetic differences in this clade than among some of the other more closely related species. More in-depth molecular studies could elucidate this issue, allowing greater taxonomic knowledge of this species.

Use and Trade

Unpublished experiments with Cladosporium perangustum isolates in Brazil have shown that this species has the potential for the production of L-asparaginase enzyme.
