Assessment Notes

Taxonomic notes

Grammothele lineata has white to greyish basidiomata, later pinkish, and might be mistaken for G. brasiliensis; however, the former has trimitic hyphal system and a partly hydnoid surface with dots of numerous dark bundles of skeletal hyphae. Grammothele lineata is similar to G. denticulata in having grayish pores, but has larger pores (2–4 per mm) and oblong-ellipsoid spores (4.6–6.5 3 2.6–3.2 mm) (Zhou & Day 2012, Ryvarden 2015, Hyde et al. 2019).

Why suggested for a Global Red List Assessment?

Geographic range

The species in known in 14 countries. The species has a wide distribution, however, phylogenetic studies report that some species identified as G. lineata in other countries may actually be another species.

Population and Trends

There are about 220 records of this species in GBIF, about half of them in Brazil. Although not a rare species, it is not very common.

Population Trend: Uncertain

Habitat and Ecology

In Brazil the species is found in Amazonia, Atlantic Forest and Caatinga.

Subtropical/Tropical Moist Lowland ForestSubtropical/Tropical Dry Shrubland


The species is well distributed in Brazil. However, the Amazon has currently the highest rates of deforestation in the last decades, the Atlantic Forest is a hotspot and Caatinga is threatened by desertification.
