“…Symptoms on twigs and needles inoculated with P. funerea were similar to those observed in the field where the fungus was collected and to those described previously (Phillips and Burdekin 1992;Panconesi and Vettori 1994;Mordue 1998). In addition to this result, in each of the experiments, both laboratory and field based, all the isolates caused necroses of greater length than those in the controls, confirming the potential role of this fungus as primary pathogen able to infect healthy plant material in conditions favourable to the pathogen (Gonthier and Nicolotti 2002;Sousa et al 2004).…”

“…According to the literature, Q. pyrenaica is not a normal host of P. funerea, which hitherto has been mainly recovered from conifer species (Mordue 1998). However, those isolates were recovered from dead leaves, and it is known that dead or dying tissues can be colonized by parasites (Sinclair et al 1993;Prospero et al 2006) or saprophytic fungal species other than those usually found in healthy tissues (Petrini et al 1989;Kowalski and Kehr 1996).…”

“…2004). Within those hosts, it was isolated mainly from conifers (M ordue 1998), although it has also been observed on several broadleaved genera, including Quercus (O sorno and D iez 2002; M artín‐ P into et al. 2004).…”

The fungal pathogen Pestalotiopsis funerea principally attacks conifer species, causing necrosis on infected tissues, and sometimes death of plants. The main objectives of this study were to determine optimal in vitro growth conditions for Spanish isolates of P. funerea and to evaluate the virulence of these isolates on Cupressus arizonica under field and laboratory conditions, with the goal of verifying possible correlations between these variables. Eight isolates of P. funerea derived from C. sempervirens, C. arizonica and Quercus pyrenaica were used in the assays. In the growth rate experiment, five culture media (PDA, MEA, WA, PCA and TAKAY medium) and six temperatures (5, 10, 15, 20, 25 and 30°C) were evaluated. In the pathogenicity tests, two different experiments were carried out: (i) laboratory inoculations used 30-mm-long twigs of C. arizonica; (ii) in field inoculations, twigs of C. arizonica were inoculated with mycelia through wounds. Four months after inoculation, length of the twigs affected by necrosis were measured. The results suggested that Spanish P. funerea isolates had optimum growth at 25°C on TAKAY medium. The fungus caused substantial necroses on C. arizonica twigs after inoculation in both excised twigs and on adult C. arizonica trees. A positive relationship between inoculations carried out under laboratory and field conditions was found. No clear relationships were found between cultural characteristics and pathogenicity for P. funerea.

“…In older cultures spermatia-like phialospores (Crowe, 2008) were produced, but sexual structures were absent. The pathological and morphological characteristics suggested that the fungus was Sclerotium cepivorum (Mordue, 1976), the causal agent of white rot of Allium species. One isolate from garlic was deposited in the PPIHAS Mycology Collection (WDCM824) under the accession number H-292.…”
