“…En Chile, inmediatamente de repor tada la presencia de Neonectria fuckeliana asociada a crancos en troncos de P. radiata (Morales, 2009), se abordó la caracterización macro y micromorfológica del estado anamorfo Acremonium (Molina, 2010;Molina et al 2012). Lo mismo ocurrió con C. cylindroides, luego de ser reportado (Morales et al 2013). Ello, como una forma de dilucidar el rol que tanto el teleomorfo como estos dos anamor fos pueden estar representando en la formación de cancros en troncos de P. radiata.…”

“…El análisis morfológico de estos cuerpos fructíferos desarrollados in vivo, permitió caracterizar taxonómicamente a este agente como Cylindrocarpon cylindroides var. tenue (Morales et al 2013) el cual, según Booth 1959y Castlebury et al 2006, corresponde al estado anamorfo de Neonectria fuckeliana.

“…The Cylindrocarpon ‐like morph produces white or pale yellow sporodochia erumpent from the cortex. The macroconidia are hyaline, cylindrical and straight or slightly curved with rounded ends (González & Chaverri, 2017; Morales et al, 2013; Osorio et al, 2014). The sexual morph produces perithecia clustered on bark with bicellular ascospores that are hyaline, guttulate, ellipsoidal with a constricted septum and without overlapping ends in the ascus (González & Chaverri, 2017).…”

Life cycle and in vitro sporulation dynamics ofCorinectria constricta,the causal agent ofPinus radiatastem canker, in Chile

In 2008, a canker disease caused by the fungus Corinectria constricta was detected in southern Chile. The causal agent was previously identified as Neonectria fuckeliana (now Corinectria fuckeliana), which has been associated with stem cankers in Pinus radiata plantations in New Zealand since the 1990s. Many basic aspects of the life cycle of C. constricta remain unknown. The current study aimed to (a) document the periods during which C. constricta fruiting bodies are present in P. radiata plantations and associated factors; (b) determine the C. constricta life cycle in P. radiata plantations in southern Chile; and (c) evaluate, under in vitro conditions, the sporulation dynamics of ascospores. The first and second aims were carried out by evaluating affected plantations every 15 days, identifying asexual and sexual fungal structures, and recording the time periods when the structures were present. The third aim was achieved with in vitro tests in Petri dishes simulating humidity chambers. The life cycle was characterized by the presence of sporodochia from the Cylindrocarpon‐like (asexual form of C. constricta) morph during the autumn of 2012 (March–May). Subsequently, perithecia began to form on the sporodochia during April of 2012, taking approximately 3 months to mature (May–July), persisting for the rest of the year and providing inoculum to infect new trees. The development of perithecia in winter demonstrates that this is the most important period for dispersal and infection. In terms of sporulation dynamics, perithecia can release ascospores up to eight days following a wetting event; without this event, the spores are not released.
