Tremella fuciformis (family Tremellaceae, ordem Tremellales, class Basidiomycetes) is probably one of the most beautiful fungi growing in subtropical and tropical areas, or even temperate zones. It was first found in Brazil but has developed to an artificially cultivated species in Taiwan, China and some other countries in Asia (Urben, 2006, 2010). It is clearly associated with Ascomycetes in the field, especially Hypoxylon spp., however, unlike other Tremella mycoparasites in basidiocarps of Basidiomycetes, the real host-relationship of this group is still not investigated.
