Neonectria ditissima
species of fungus
Neonectria ditissima (syn. Neonectria galligena) is a fungal plant pathogen. It causes cankers that can kill branches of trees by choking them off. Apple and beech trees are two susceptible species.
Host range
Neonectria ditissima host range encompass a variety of hardwood tree species such as, Fagus, Populus, Salix, Betula and Acer species. These tree species population are present in both America and Europe. Phylogenetic studies have revealed genetic divergence among both populations, at specific loci (ß-tubulin, RPB2). However, due to high levels of within-population diversity of the American populations, it has been hypothesized that America is N. ditissima place of origin.
Disease management
Neonectria ditissima is a difficult pathogen to eradicate—but there are many ways to limit its spread and infection rate. Effective control requires a combination of cultural and chemical treatments.
“Neonectria ditissima” enters the record as species of fungus. Crown Archives preserves that source wording while asking what Neonectria, ditissima and species can confirm, complicate or overturn.
Why this record matters
“Neonectria ditissima” is worth following because a concise public description often conceals a longer documentary argument. Here, Neonectria, ditissima and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 29, 2025. The linked authority identifier is Q10597558. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
