Assessment Notes

Taxonomic notes

The reliable features to recognize G. orbiforme are its rigid basidiocarp with a weakly to strongly laccate, partly laccate or dull pileus, variably brown context, ellipsoid to ovoid basidiospores with fine and short echinulae, and purplish brown pore surface at maturity (Wang et al. 2014). Is is possible that the South American specimens represent G. fornicatum, while the Asian specimens represent the true G. orbiforme (Wang et al. 2014).


Why suggested for a Global Red List Assessment?


Geographic range

The species in known in 4 countries. However, Wang et al. (2014) report this species in several other countries.


Population and Trends

There are about 326 records of this species in GBIF, most of them in New Zealand. However, the South American specimens may represent G. fornicatum.

Population Trend: Uncertain


Habitat and Ecology

In Brazil, the species is found only in Atlantic Forest. with few records in the Amazon Forest.

Subtropical/Tropical Moist Lowland Forest

Threats

In Brazil, this species is not well distributed, with most reports in Atlantic Rain Forest, a hotspot.
