“…This form of vegetative propagation combined with mycelial transfer from root to root can under certain circumstances result in the formation of very large clonal individuals (Smith et al 1992;Ferguson et al 2003;Bendel et al 2006a). More often, however, the estimated size of an Armillaria genet measures less than one hectare (Brazee et al 2012a;Travadon et al 2012;Dutech et al 2017;Lehtijarvi et al 2017;Tsykun et al 2017).…”

The basidiomycete genus Armillaria s.l. (Armillaria s.s. and Desarmillaria) has a worldwide distribution and plays a central role in the dynamics of numerous woody ecosystems, including natural forests, tree plantations for timber production, orchards, vineyards, and gardens. Early studies have shown that all Armillaria species are capable of degrading dead woody substrates causing white rot. Moreover, most species exhibit a parasitic ability, and can be considered as facultative necrotrophs. Although over the years extensive research has been conducted on the phylogeny, biology, and ecology of different Armillaria species, numerous theoretical and applied questions remain open. Recently published studies have provided new perspectives, the most significant of which we present in this review. First, new investigations have highlighted the importance of a multilocus approach for depicting the phylogeny of the genus Armillaria. Second, the importance of clonality and sexuality for the different species is now better described, enabling a more accurate prediction of population dynamics in various environments. Third, genome sequencing has provided new insights into genome evolution and the genetic basis of pathogenicity and wood degradation ability. Fourth, several new studies have pointed out the possible influence of climate change on Armillaria distribution, biology and ecology, raising questions regarding the future evolution of Armillaria species and their effect on ecosystems. In this review, we also give a state-of-the-art overview of the control possibilities of parasitic Armillaria species. Finally, we outline some still open questions in Armillaria research, the investigation of which will strongly benefit from recent methodological advances.

“…Armillaria species occur all across Europe [85,121,[123][124][125][126][127][128][129]. The most common Armillaria species on pines in north-east Europe are A. borealis and A. ostoyae [130,131], while in Maritime and south-east Europe, A. cepistipes, A. gallica, A. mellea, and A. ostoyae are the most common [121,122,129,132,133]. Armillaria species can be aggressive primary pathogens as well as secondary pathogens of stressed trees and saprophytes [134].…”

Pines are major components of native forests and plantations in Europe, where they have both economic significance and an important ecological role. Diseases of pines are mainly caused by fungal and oomycete pathogens, and can significantly reduce the survival, vigor, and yield of both individual trees and entire stands or plantations. Pine pitch canker (PPC), caused by Fusarium circinatum (Nirenberg and O’Donnell), is among the most devastating pine diseases in the world, and is an example of an emergent invasive disease in Europe. The effects of microbial interactions on plant health, as well as the possible roles plant microbiomes may have in disease expression, have been the focus of several recent studies. Here, we describe the possible effects of co-infection with pathogenic fungi and oomycetes with F. circinatum on the health of pine seedlings and mature plants, in an attempt to expand our understanding of the role that biotic interactions may play in the future of PPC disease in European nurseries and forests. The available information on pine pathogens that are able to co-occur with F. circinatum in Europe is here reviewed and interpreted to theoretically predict the effects of such co-occurrences on pine survival, growth, and yield. Beside the awareness that F. circinatum may co-occurr on pines with other pathogens, an additional outcome from this review is an updating of the literature, including the so-called grey literature, to document the geographical distribution of the relevant pathogens and to facilitate differential diagnoses, particularly in nurseries, where some of them may cause symptoms similar to those induced by F. circinatum. An early and accurate diagnosis of F. circinatum, a pathogen that has been recently introduced and that is currently regulated in Europe, is essential to prevent its introduction and spread in plantings and forests.

“…Armillaria mellea attacks vineyards, orchard trees and deciduous trees, but can also infect young conifers. Armillaria ostoyae is regarded as a parasite of coniferous trees, while A. gallica , A. borealis and A. cepistipes are all three generally considered as saprophytes (Guillaumin et al., 1993; Lehtijärvi, Dogmus‐Lehtijärvi, Aday Kaya, Ünal, & Woodward, 2017).…”

Species of the genus Armillaria (Fr.:Fr.) Staude are widely distributed Basidiomycota belonging to the Agaricomycetes, and most are potential root-rot pathogens with a broad host range. Using interfertility tests, Korhonen (1978) separated European Armillaria within the annulate mellea complex into five biological groups later described as five biological species based on different ecological and physiological criteria. These species include Armillaria mellea (Vahl.:Fr.) Kummer, Armillaria ostoyae (Romagnesi) Herink, Armillaria gallica Marxmuller & Romagnesi, Armillaria borealis Marxmuller & Korhonen and Armillaria cepistipes Velenossky. In addition, two exannulate species include Armillaria ectypa (Fr.) Lamoure, found in peat bogs as a saprophyte, and Armillaria tabescens (Scop.:Fr) Emel, a forest species commonly found in southern Europe, usually considered as a saprotroph, but at least once reported in Europe as a weak parasite (Tsopelas & Tjamos, 1997). Armillaria mellea attacks vineyards, orchard trees and deciduous trees, but can also infect young conifers. Armillaria ostoyae is regarded as a parasite of coniferous trees, while A. gallica, A. borealis and A. cepistipes are all three generally considered as saprophytes (
