“…The analysis of data on synanamorphs associated (co-occurring) with Asteromella species in the type materials (Appendix 1) reveals that Asteromella fungi had been recorded either with Ramularia or Septoria morph. This is congruent with the earlier assumption of Aa and Vanev [5], as well as recent results of molecular studies that have proven Ramularia and Septoria to be different clades of Mycosphaerella s. l. [55,72]. The only exception is Asteromella (= Phyllosticta) buphthalmi, described by Allescher [86] as co-occurring with Ramularia buphthalmi.…”

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.

Cercosporoid diseases of Citrus

et al. 2015

Citrus leaves and fruits exhibiting disease symptoms ranging from greasy spot, yellow spot, small or large brown spot, black dot, and brown dot were sampled from Fujian, Guangdong, Guizhou, Hunan, Jiangxi, Yunnan, Zhejiang provinces and the Guangxi Zhuang Autonomous Region in China. In total 82 isolates representing various cercosporoid genera were isolated from these disease symptoms, which were supplemented with eight Citrus cercosporoid isolates collected from other countries. Based on a morphological and phylogenetic study using sequence data from the nuclear ribosomal DNA's ITS1-5.8S-ITS2 regions (ITS), and partial actin (act), b-tubulin (tub2), 28S nuclear ribosomal RNA (28S rDNA) and translation elongation factor 1-a (tef1) genes, these strains were placed in the following genera: Cercospora, Pallidocercospora, Passalora, Pseudocercospora, Verrucisporota and Zasmidium. All isolates tended to be sterile, except the Zasmidium isolates associated with citrus greasy spotlike symptoms, which subsequently were compared with phylogenetically similar isolates occurring on Citrus and other hosts elsewhere. From these results four Zasmidium species were recognized on Citrus, namely Z. indonesianum on Citrus in Indonesia, Z. fructicola and Z. fructigenum on Citrus in China and Z. citri-griseum, which appears to have a wide host range including Acacia, Citrus, Eucalyptus and Musa, as well as a global distribution.

“…Phylogenetic relationships of fungi of the genus Septoria have been the subject of an ongoing research of some Dutch researches Verkley et al 2013). Mycologists constantly ask the following questions: BWhat are Septoria?^and BWhich fungi belong to the genus Septoria?^The studies conducted by the above-mentioned authors showed that we can not clearly define the genus based solely on its morphology or host plants infected by these fungi.…”

“…Fungi of the genus Septoria (teleomorph Mycosphaerella) belong to the widespread pathogens of crops and wild plants in all regions of the world (Farr et al 1995;Verkley et al 2004Verkley et al , 2013Marcinkowska 2012;Zalewska et al 2015). Septoria spp.…”

“…Sexual status of this species is unknown and only a small number of species produce teleomorphs, which are classified to the genus Mycosphaerella Johanson (Dothideales) (Verkley et al 2004). Mycological studies carried out at the Department of Plant Protection indicated variation in the morphological features and growth conditions of Septoria carvi compared to other Septoria species colonizing various plants of the family Apiaceae Zalewska 2008Zalewska , 2012Zalewska , 2013Verkley et al 2013;Quaedvlieg et al 2013). Based on our preliminary research, it is difficult to determine the affiliation of the studied isolates, especially by the analysis of growth, development and morphological structures of S. carvi in different culture conditions (Zalewska 2012).…”

Genetic variability within Septoria carvi Syd.- a pathogen of caraway Carum carvi L

et al. 2017

Genetic variability within Septoria carvi isolates obtained from various organs of caraway cultivated in south-eastern and central Poland was studied using the RAPD-PCR technique. The tests were performed using randomly selected primers. The DNA profiles obtained using four primers proved useful in determining genetic variability among the genotypes of Septoria carvi isolates. The present study characterized the differences in the nucleotide sequence within the internal transcribed spacer region of rDNA (ITS1, 5.8S, ITS2) of selected S. carvi isolates and reference strains of Septoria spp. Moreover, eight isolates were sequenced for three loci: actin, calmodulin and translation elongation factor 1-alpha, and the obtained sequences were compared with the sequences of Septoria reference strains affecting other plants of the family Apiaceae. Phylogenetic analysis showed distinct differences of the tested isolates, which allowed to treat them Septoria carvi species affecting the above-ground organs of caraway Carum carvi L. This study is the first report on the genetic characteristics of the species S. carvi.
