Remarks (internal):Traditionally Nectria has been used for perithecial fungi with brightly-colored ascomata and 2-celled, hyaline ascospores, but Rossman includes species with phragmosporous ascospores as well, on the basis of ascomal wall structure and the anamorph. Some authors have restricted Nectria to non-stromatic species, placing species with a stroma in Creonectria Seaver or Dialonectria (Sacc.) Cooke. Sphaerostilbe Tul. has been used for species with a stilboid anamorph, and Neuronectria Munk has been used for species with striate ascospores in which the ascomata collapse and become cupulate following ascospore discharge. All are included in Nectria.

Description:NECTRIA (Fr.) Fr.
Ascoma an ostiolate perithecium, solitary to gregarious, with or without a stroma, if stromatic, perithecium superficial or partially immersed in stroma, fleshy, brightly-colored to occasionally light brown, subglobose to globose or obpyriform. Ascomal wall pseudoparenchymatous or prosenchymatous, walls of outermost cells pigmented and somewhat thickened, inner cells hyaline and thin-walled. Centrum containing apical paraphyses. Asci unitunicate, clavate to cylindrical, with persistent wall, with or without an apical ring, nonamyloid, straight to curved, 8-spored. Ascospores 2-several-celled, ellipsoid to long fusiform, hyaline to brownish, smooth, striate or verrucose. (Fig. A-B,D).
Anamorphs: Acremonium, Antipodium, Botryocrea, Calostilbella, Cephalosporiopsis, Ciliciopodium,
Cylindrocarpon, Cylindrocladiella, Cylindrocladium, Dendrodochium, Didymostilbe, Fusarium, Gliocladium, Kutilakesopsis, Myriothecium, Rhizostilbella, Stilbella, Tubercularia, Verticillium, Virgatospora, Volutella, Zythia, and Zythiostroma.
Habitat: Occurring on a wide range of woody and herbaceous plants and cryptogams as saprobes or parasites, and in soil.
Representative species: Nectria cinnabarina (Tode: Fr.) Fr., (Anam. Tubercularia vulgaris Tode: Fr.), a stromatic species that causes canker diseases of trees and shrubs, and N. haematococca Berk. & Broome [Anam. Fusarium solani (Mart.) Sacc.], a nonstromatic species that causes root diseases of crop plants.
