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?
