I. Peronosporales and Erysiphales. Acta Mycol. 40 (2): 223-250, 2005 . The present paper begins a new series of studies investigating the occurrence of phytopathogenic micromycetes in Central Poland. Fungi of the orders Peronosporaies and Elysiphales are discussed in part one . Relevant knowledge on the subject is surveyed, and a list of published records (46 taxa) as well as the findings collected by the present authors (99 taxa) is provided. The list comprises 2 species new for biota of Poland - Microsphaera deutziae Bunkina and Microsphaera elevata Burrill, 10 rare and many common fungal species that had not been previously recorded in this area as well as 21 plant taxa, mostly species of deliberate or accidental anthropogenic origin, that are new hosts of the parasites formerly listed in Poland. Key words: parasitic fungi, Peronosporales, Erysiphales, distribution, Central Poland INTRODUCTION The species belonging to Peronosporales and Erysiphales in Poland have been studied welL Monographs (Kochman and Majewski 1970; Salata 1985) provide data on the morphology, ecology and distribution of 200 and 112 representatives, respectively. The studies are based on analyses of herbarium materials as well as on the records repo rted in 380 Polish sources published between 1830 and 1983. Extensive research projects on the occurrence of fungi in Poland, including phytopathogenic micromycetes, were carried out in the most important protected areas: national parks and nature reserves. Consequently, the mycoflora has been examined quite well in the following na tional parks: Kampinoski N. P. (Maj ewski 1967), Bialowieski N. P. (Majewski 1971; Falinski and Mulenko eds 1992-1996), Ojcowski and Pieninski N. P. (Kucmicrz 1973,1977), Poleski N. P. (Mulenko 1989), projected Jurajski N. P. (R uszkiewicz 2000a), Slowinski N. P. (Ad amska and Blaszkowski 2000; Adamska 2001), and Tatrzanski N. P. (Mulenko, K 0 z low s k a and S a I a t a 2004 and the literature cited therein). Areas such as the Notec valley (M i ch al sk i 1965,1982), the Wyryna Lubelska Upland (R om as ze- 224 M. Ruszkicw icz-Michalska, M. Michalski wska-Salata 1977) and the Bug valley (Dani lkiew icz 1987) have also been investigated in relative depth. Although research on fungi in areas particularly strongly affected by human activity and subjected to constant anthropopressure, that is in urbanised and industrial areas, developed at the same time, projects investigating fungi in such areas are exceptionally rare (Lawrynowicz 1982; Kr e i se l and Amelang 2001; Lawrynowicz, Buj ak iewi cz and Mulenko 2004; Mi l evoj 2004). The occurrence of microscopic plant pathogens has been examined only in few major Polish towns and cities: Olsztyn, Plock, Szczecin, Swinoujscie and Torun (D y n owska 1994;Dynowska, F iedorowicz and Kub iak 1999; Holownia and Kostrzewska 1991; Madej 1971,1972), Sometimes fragmentary data on rare or new species observed in urbanised areas can also be found in other sources (R 0m asze wska -S ala ta, Salata and Mulenko 1982; Wolczanska and Mul e nko 2002; Ru szk iewic z - Michalska and Mulenko 2003) . The presence of the dive rsificd flora, including many exotic plant species, both introduced accidentally and cultivated, is an important feature of urban and industrial areas (0 e m m e II 1980); it is, however, elabo rated on by few researchers studying botanical gardens, arboreta and allotment gardens (Zaleski and Madej 1964; Madej 1969, 1971a; Kalinowska-Kucharska 1998; ｐｩｾｴ･ｫ＠ 2000a, 2003; Mul enko and Wojdyl o 2002). Numerous recent physiographic or mycosociological studies contribute to the knowledge on species richness and the distribution of microscopic parasitic fungi in Poland. As a result, 39 species of downy mildews and 4 taxa of powdery mildews have \ ( Fig. I. D istribution of th e localities offungaJspecies in Central Poland based on the literature data. Phytopathogenic micromycetes 225 been added to the list of these fungi known in Poland (M a j c w ski and R us z k i e wicz - Michalska 2005, unpub!'; Ruszkiewicz-Michalska 2005). Although these reports are numerous (P i ｾ＠ t e k 2000, 2004; A dam s k a 2002; W a I c zan s k a and Mulenko 2002; Ruszkiewicz-Michalska and Michalska-Hejduk 2003), only few of them provide findings that are consistent, complete, and deal with areas of Poland that have not been examined before. An inclusive app roach is adopted by, for instance, Kalinowska-Kucharska and Kadlubowska (1993), Romaszewska - Salata and Wolczaiiska (1997), Dynowska et a!. (1999) and Czerniawska (2001). While the mycoflora of macromycetes in L6di, as one of the few Polish urban agglomerations, has been examined in relative depth (Lawrynowicz 1982,1990; Stasinska 1994; Lawrynowicz, Kalucka and Sumorok 2001), the occurrence of microscopic fungal pathogens in the area of the city and the L6di voivodeship, situated in the heart of Central Poland (Papiiiska 1993), has been poorly studied. A list of published records comprises 46 fungal taxa collected in 19 localities (Fig. 1). The findings are based on two groups of sources: i) reports of the Departments of Plant Conservation published before World War II, and ii) 6 recent floristic studies dealing mostly with powdery mildews. MATERIALS AND METHODS For analysis of published data the following studies were used: Garbowski (1925, 1935), Garbowski and luraszk6wna (1933), Leszczenko (1937), Kadlubowska (1963), Kalinowska-Kucharska (1997,1998), joint publications by Kadlubowska and Kalinowska - Kucharska (1993, 1997) and Ruszkicwicz-Michalska and Mulenko (2003). As the result the list of 43 taxa of Erysiphales and 3 species of Peronosporales was obtained. Original findings from L6di and its vicinity (Figs 1, 2) come mostly from the present authors' studies (295 records) carried out in the years 1995-2005. In the area of Ladi 6 sampling sites have been distinguished (Fig. 2). Unpublished materials deposited in the Herbarium Universitatis Lodziensis collected by Dominika Franoszek (26 records), Ewa Kalinowska-Kucharska (9), AJeksandra Kotynia (3), Anna Marciniak (18) and a number of older exsiccata were also included in the analysis. Available herbarium materials documenting the findings given in sources published between 1963 and 2003 were also reviewed and verified. The fungal species were determined using the monographs written by K 0 c hman and Majewski (1970) and Braun (1987, 1995); hosts were identified according to Szafer, Kulczyiiski and Pawlowski (1986) and Rutkowski (2004). The nomenclature of host species follows the checklist of vascular plants of Poland (M ire k el al. 2002), while that of parasites follows Ihe checklist of microscopic fungi (M u len k a and M aj ews ki eds 2005 unpub!.). Host species observed in Poland for the first time are marked with an asterisk (*). The studied materials are deposited in the Herbarium Universitatis Lodziensis (LOD) in the collection parasitic fungi labelled as PF. 226 M. Ruszkiewicz-M icha lska, M.

RESULTS 27 species of the orders Peronosporaies and 81 taxa of Erysiphales are listed below. They constitute 11 % and 71 % of species of these groups occurring in Poland, respectively (Majewski and Ruszkiew i cz-Michals k a 2005 unpubl.). The list comprises two species new for biota of Poland - Microsphaera deulziae Bunkina and Microsphaera eievala Burrill, 10 rarc and many common fungal species; more than a half of them (62 taxa), however, had not been previously recorded in Central Poland. The majority of plant species that are new hosts of their parasites in Poland are taxa introduced and distributed by man consciously or accidentally. Most documented cases of a rapid transmission of phytopathogenic fungi takes place when a fungus or its host is an exotic species, and they have not coevolved (D e i g h ton 2003). Because of an insufficient number of findings from certain types of habi tats and areas subjected to increased human impact, the discussion on the expansion, invasion and hemerophoby of many taxa of parasitic fungi is frequently omitted in releva nt literature (R u sz k iewicz - Mic h alsk a and M i ch als ki 2005). It is thus necessary to fill in the gap in the knowledge on the occurrence of phytopathogenic micromycetes Phytopathogenic micromycetes 227 by providing localities of common species, given in, for example, unpublished master's theses. Although the findings given below are based on test studies, and not observations carried out regularly, they do provide information on the taxonomic diversity and spread of phytopathogenic micromycetes in urban areas. As studies by D Ynow s k a (1993,1994,1996) and Dynowska and Sucharzewska (2001) show, this type of findings help determine sensitivity of fungi to air pollution. The value of such data can also be assessed by their contribution to comprehensive studies such as checklists, and to studies monitoring changes occurring in artificial ecosystems. Parts II and III of the series of studies on phytopathogenic micromycetes in Central Poland will deal with successive groups of fungi: rusts, smuts and anamorphic fungi, including a final discussion and conclusion.

Notes. S ala t a (1985) using the description given by Kadlubowska, assumed that the fungus should be classified as L eveillu/ageralliaceamm Eliade, but because of the lack of the herbarial material he could not verify this record. Accordi ng to the newer taxonomy of powdery mildews (Braun 1995), the fungi reported on Gerallium spp. sub E. communis or E. polygoni should belong to the Erysiphe geralliaceanml. The majority of these records cannot be verified and that is why the morphology and distribution of the species is insufficiently known; this taxon appears to be nOt rare. Bra u n (I.e.) mentioned Poland among countries in which the taxon has been rcported only on G. pratellse and he presumably have made th is o n the basis of Kadtubowska's record. In Poland £. geraniacearum has been however recorded also (sub £. communis) by J ac ky (1900) from Pr6szk6w ncar Opole on Geranium molle and from Wierzbno near Warszawa by Bt onski (1896) on G. robeniallum, which has not been mentioned by Bra u n (1995) and Fa rr et al.
