“…According to rRNA gene analysis, D. fagi is most closely related to Aureobasidium pullulans, a yeast that has previously been studied for biocontrol purposes (35,46). In our research we found that D. fagi may be useful for application on fresh-cut apples to control food-borne pathogens such as S. enterica serovar Poona and L. monocytogenes.…”

Fresh-cut apples contaminated with either Listeria monocytogenes or Salmonella enterica serovar Poona, using strains implicated in outbreaks, were treated with one of 17 antagonists originally selected for their ability to inhibit fungal postharvest decay on fruit. While most of the antagonists increased the growth of the food-borne pathogens, four of them, including Gluconobacter asaii (T1-D1), a Candida sp. (T4-E4), Discosphaerina fagi (ST1-C9), and Metschnikowia pulcherrima (T1-E2), proved effective in preventing the growth or survival of food-borne human pathogens on fresh-cut apple tissue. The contaminated apple tissue plugs were stored for up to 7 days at two different temperatures. The four antagonists survived or grew on the apple tissue at 10 or 25°C. These four antagonists reduced the Listeria monocytogenes populations and except for the Candida sp. (T4-E4), also reduced the S. enterica serovar Poona populations. The reduction was higher at 25°C than at 10°C, and the growth of the antagonists, as well as pathogens, increased at the higher temperature.

“…There have been few molecular studies on this genus. Lumbsch & Lindemuth (2001) used LSU and SSU gene data to analyze the major lineages of Dothideomycetes in which the Myriangium species were included in the order Myriangiales. Schoch et al (2006) used M. duriaei and four Elsinoe spp.…”

The family Myriangiaceae is relatively poorly known amongst the Dothideomycetes and includes genera which are saprobic, epiphytic and parasitic on the bark, leaves and branches of various plants. The family has not undergone any recent revision, however, molecular data has shown it to be a well-resolved family closely linked to Elsinoaceae in Myriangiales. Both morphological and molecular characters indicate that Elsinoaceae differs from Myriangiaceae. In Elsinoaceae, small numbers of asci form in locules in light coloured pseudostromata, which form typical scab-like blemishes on leaf or fruit surfaces. The coelomycetous, "Sphaceloma"-like asexual state of Elsinoaceae, form more frequently than the sexual state; conidiogenesis is phialidic and conidia are 1-celled and hyaline. In Myriangiaceae, locules with single asci are scattered in a superficial, coriaceous to sub-carbonaceous, black ascostromata and do not form scab-like blemishes. No asexual state is known. In this study, we revisit the family Myriangiaceae, and accept ten genera, providing descriptions and discussion on the generic types of Anhellia, Ascostratum, Butleria, Dictyocyclus, Diplotheca, Eurytheca, Hemimyriangium, Micularia, Myriangium and Zukaliopsis. The genera of Myriangiaceae are compared and contrasted. Myriangium duriaei is the type species of the family, while Diplotheca is similar and may possibly be congeneric. The placement of Anhellia in Myriangiaceae is supported by morphological and molecular data. Because of similarities with Myriangium, Ascostratum (A. insigne), Butleria (B. inaghatahani), Dictyocyclus (D. hydrangea), Eurytheca (E. trinitensis), Hemimyriangium (H. betulae), Micularia (M. merremiae) and Zukaliopsis (Z. amazonica) are placed in Myriangiaceae. Molecular sequence data from fresh collections is required to confirm the relationships and placement of the genera in this family.

“…Her subclasses were determined based on the morphological characteristics of the centrum, including the absence, presence and types of hamathecial tissues (Schoch et al 2009). Recent studies using multigene analysis, coupled with morphology, have provided the basis for classification of the Dothideomycetes (Liew et al 2000, Lumbsch & Lindemuth 2001, Spatafora et al 2006, Schoch et al 2009, Zhang et al 2012, Hyde et al 2013. Several recent publications on the genera of Dothideomycetes (Wu et al 2011, Liu et al 2012, Zhang et al 2012, Hyde et al 2013, Ariyawansa et al 2013, Li et al 2014, b, Tian et al 2014) have aimed to provide a natural classification of this large class.…”

The generic types of four genera with unclear placement in Dothideomycetes were re-examined. These genera were hitherto poorly illustrated or described. The type specimens of Cocconia (C. palmae), Dianesea (D. palmae), Endococcus (E. rugulosus) and Lineostroma (L. banksiae), were re-examined in order to determine their familial and higher level placements, according to their morphology and based on modern taxonomic concepts. A resume of the history along with descriptions and illustrations of these genera are provided. Endococcus and Lineostroma are placed in families Lichenotheliaceae and Didymosphaeriaceae, respectively, based on morphology. The placement of Cocconia within Parmulariaceae is confirmed. Dianesea is retained in Dothideomycetes genera incertae sedis as it is not typical of any existing family of Dothideomycetes. Fresh collections of these genera are needed for further study, so that they can be epitypified and molecular data is needed to validate their phylogeny and natural classification.
