Gnomoniopsis smitholvilgyi (described in Australia in 2012) and its synonymous Gnomoniopsis castaneae (described in Europe in 2012) on the basis of the current knowledge must be considered a cryptic species with a wide geographical distribution (most of the natural range of Castanea sativa and the cultivation area of C. sativa and its hybrids). This is a precautionary categorization since there is ecological and taxonomic piece of evidence suggesting that G. smitholvilgyi (G. castaneae) is part of the endophytic fungal community of European chestnut and its hybrids, and that the recent outbreak of associated diseases is strictly dependant on external biotic (Chinese Gall Wasp) and abiotic (climate changes ) factors.

Based on the Editorial Board Member, it must be considered as a cryptic species with a wide geographical distribution
