“…Later, it was reclassified as P. tracheiphila and considered a member of the subgenus Plenodomus due to the presence of thick-walled cells in the pycnidial scleroplectenchymatous tissues [7]. Many species in this subgenus have Leptosphaeria teleomorphs and/or Phialophora synanamorphs [8]. Although a molecular phylogenetic study has shown a relationship between P. tracheiphila and Leptosphaeria species [9], the teleomorph of the mal secco fungus has not yet been identified.…”

This chapter deals with major endemic and emerging fungal diseases of citrus as well as with exotic fungal pathogens potentially harmful for citrus industry in the Mediterranean region, with particular emphasis on diseases reported in Italy and Maghreb countries. The aim is to provide an update of both the taxonomy of the causal agents and their ecology based on a molecular approach, as a preliminary step towards developing or upgrading integrated and sustainable disease management strategies. Potential or actual problems related to the intensification of new plantings, introduction of new citrus cultivars and substitution of sour orange with other rootstocks, globalization of commerce and climate changes are discussed. Fungal pathogens causing vascular, foliar, fruit, trunk and root diseases in commercial citrus orchards are reported, including Plenodomus tracheiphilus, Colletotrichum spp., Alternaria spp., Mycosphaerellaceae, Botryosphaeriaceae, Guignardia citricarpa and lignicolous basidiomycetes. Diseases caused by Phytophthora spp. (oomycetes) are also included as these pathogens have many biological, ecological and epidemiological features in common with the true fungi (eumycetes).

“…The Canada thistle was originally not identified as a host of Ph. exigua (van der Aa 2000, Boerema et al 2004) but could later be confirmed as such (Bithell and Steward 2001, Waipara 2003, Bilder and Berestetsky 2006. Inoculation experiments showed that an artificial infection with the fungus is possible, but with inconsistent results between different isolates.…”

Plant pathogens as biocontrol agents of Cirsium arvense – an overestimated approach?

Cirsium arvense is one of the worst weeds in agriculture. As herbicides are not very effective and not accepted by organic farming and special habitats, possible biocontrol agents have been investigated since many decades. In particular plant pathogens of C. arvense have received considerable interest and have been promoted as “mycoherbicides” or “bioherbicides”. A total of 10 fungi and one bacterium have been proposed and tested as biocontrol agents against C. arvense. A variety of experiments analysed the noxious influence of spores or other parts of living fungi or bacteria on plants while others used fungal or bacterial products, usually toxins. Also combinations of spores with herbicides and combinations of several pathogens were tested. All approaches turned out to be inappropriate with regard to target plant specificity, effectiveness and application possibilities. As yet, none of the tested species or substances has achieved marketability, despite two patents on the use of Septoria cirsii and Phomopsis cirsii. We conclude that the potential of pathogens for biocontrol of C. arvense has largely been overestimated

“…The features that allow for discriminating Asteromella species from other similar genera are the fine details of the morphological structure of conidiophores and conidia. The most similar to Asteromella are small-spored Phoma s. l. (Phoma and Paraphoma [143]), distinguished by a more elliptical-or ovoidal-shaped conidia and the presence of two or more guttules. The homogenous shape of conidia of the Asteromella species is a stable character when compared to the diversely shaped spores observed in vivo in single conidiomata of Phoma section Pilosa, which have very similar conidiogenous cells [cf.…”

AbstractThe critical revision of 59 Asteromella species occurring in Poland is presented, based primarily on specimens from Poland, as well as selected herbarial materials from France, Germany, Italy, Latvia, Lithuania, Romania, Slovakia, Switzerland and Ukraine. Some exsiccata, including types of Asteromella carlinae Petr., Asteromella ludwigii Petr., Asteromella ovata Thüm., Asteromella petasitidis Petr., Depazea agrimoniae Lasch, Mycosphaerella agrimoniae Syd., Phyllosticta borszczowii Thüm., Phyllosticta cicutae Lind, Phyllosticta eupatoriicola Kabát & Bubák, Phyllosticta pleurospermi Died., Phyllosticta salicina Kabát & Bubák, Phyllosticta senecionis-nemorensis Săvul. & Sandu, Phyllosticta wandae Namysł. were also studied. Each species is accompanied by the information pertaining to host spectrum, morphology of conidiomata, conidiophores, conidiogenous cells and conidia, distribution in Poland and globally, as well as information on synanamorphs and teleomorph, if present. Two species, Asteromella moeszii Ruszkiewicz-Michalska & Mułenko spec. nov. on Pulmonaria obscura and Asteromella rupprechtii Ruszkiewicz-Michalska spec. nov. on Agrimonia eupatoria are described, based on Polish specimens. A new name, Asteromella huubii Ruszkiewicz-Michalska nom. nov., is proposed to replace Asteromella angelicae (Sacc.) Moesz ex Bat. & Peres. Nine Phyllosticta and two Depazea species were redisposed into Asteromella: Asteromella acetosae (Sacc.) Ruszkiewicz-Michalska, comb. nov., Asteromella adoxicola (Lasch) Ruszkiewicz-Michalska, comb. nov., Asteromella alnicola (C. Massal.) RuszkiewiczMichalska, comb. nov., Asteromella bacilloides (Dominik) Ruszkiewicz-Michalska, comb. nov., Asteromella prunellae (Ellis & Everh.) Ruszkiewicz-Michalska, comb. nov., Asteromella garbowskii (Gucevič) Ruszkiewicz-Michalska, comb. nov., Asteromella lysimachiae (Allesch.) Ruszkiewicz-Michalska, comb. nov., Asteromella populina (Fuckel) Ruszkiewicz-Michalska, comb. nov., Asteromella salicina (Kabát & Bubák) Ruszkiewicz-Michalska, comb. nov. Neotype of Asteromella bacilloides and a lectotype of Asteromella adoxicola are designated.Nine species reported in the literature are not confirmed to occur in Poland; this includes two species that need to be recollected [Asteromella scabiosae (Kalymb.) Vanev & Aa and Asteromella mali (Briard) Boerema & Dorenb.)], as dried specimens are scarce and deficient. Affinity of Asteromella confusa (Bubák) Petr. to Asteromella vs. Phoma is briefly disputed.
