Abstract

The 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 &amp; Bubák, Phyllosticta pleurospermi Died., Phyllosticta salicina Kabát &amp; Bubák, Phyllosticta senecionis-nemorensis Săvul. &amp; 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 &amp; 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. &amp; 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.) Ruszkiewicz-Michalska, comb. nov., Asteromella bacilloides (Dominik) Ruszkiewicz-Michalska, comb. nov., Asteromella prunellae (Ellis &amp; 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 &amp; 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 &amp; Aa and Asteromella mali (Briard) Boerema &amp; Dorenb.)], as dried specimens are scarce and deficient. Affinity of Asteromella confusa (Bubák) Petr. to Asteromella vs. Phoma is briefly disputed. New records and new data on the distribution of Asteromella species in Latvia, Poland, Slovakia, Switzerland and Ukraine are also provided. Three species are reported as new to Polish funga: Asteromella prunellae, Asteromella melampyrina and Asteromella moeszii.

Highlights

Sincere thanks are due to persons who invited me to survey Asteromella/Phyllosticta fungi at their research spaces
The aim of this study was to present the complete characteristics of Asteromella species recorded in Poland and to consider the identity of related Phyllosticta, Ascochyta and Depazea taxa deposited in reference collections in Poland
The first Polish data on fungi currently classified in the genus Asteromella date back to 1892, i.e., to Hennings’ [94] record of Phyllosticta saponariae (Fuckel) Sacc. [= Asteromella saponariae (Fuckel) Petr.]
