INTRODUCTION
Genera of phytopathogenic hyphomyceteous fungi with
relationship to Mycosphaerellaceae, such as Cercospora
Fresen., Cercosporella Sacc., Passalora Fr., Ramularia
Unger etc., show high morphological diversity in contrast
to their teleomorphs (Kirschner 2009) and cause typical
leaf spot, necrosis and chlorosis in a broad host range,
including many cultivars. Some species may develop
almost without symptoms (e.g., Cercosporella hypoestis
Hansf.), attack stems, or cause foot-rot (e.g., Ramulispora
herpotrichoides (Fron) v. Arx). A few species are
hyperparasitic (e.g. Ramularia coleosporii Sacc.). They
also have the potential to be used as biocontrol agents of
weeds (Braun et al. 2016).
Yedigöller National Park, which has seven lakes and
numerous streams, is situated in the Bolu Province in
Türkiye. According to Emberger’s climate classification,
the region is of the type having a semi-arid, upper, cold
winters Mediterranean climate of daily and seasonal
photoperiodism. This indicates that summer precipitation
is little in this region; vegetation is under the effect of the
summer drought, and the precipitation regime is Eastern
Mediterranean precipitation regime Type 1.
The research area mainly consists of mixed forest
vegetation. At lower elevations, it is covered by Fagus
orientalis Lipsky, Carpinus orientalis Mill. subsp.
orientalis, some Quercus L. species, Cornus mas L., Corylus
colurna L., Sorbus aucuparia L., Sambucus nigra L., Acer
campestre L., Acer platanoides L., Alnus glutinosa (L.)
Gaertn. Regions at upper elevations are covered with

Gymnospermae, such as Abies nordmanniana (Steven)
Spach, Pinus nigra J.F.Arnold, Pinus sylvestris L., and Taxus
baccata L. Under parts of forest-covered shrubs such as
Rhododendron ponticum L., Daphne pontica L., and
Juniperus oxycedrus L. The research area has some
marshy habitats; the aquatic plants are growing in the
lake (like Lemna L. sp., and Potamageton L. sp.), and
marsh plants are growing in near the lake (like Carex L.
ssp., Lythrum L. sp., and Typha L. sp.).
The purpose of the current study is to determine the
phytopathogenic hyphomycetes of Yedigöller National
Park and make a contribution to mycobiota of Türkiye.
MATERIALS AND METHODS
Specimens of fungi were collected from Yedigöller
National Park in Bolu Province of Türkiye between 2018
and 2021. The Flora of Türkiye and the East Aegean
Islands was used to identify the host plants (Davis 1965
85). A Leica DM E light microscope was used to examine
and measure the preparations prepared from the host
tissue. A Leica EZ4D stereo microscope was used for
close-up photos of infected host surfaces. Taxa were
identified using relevant literature (Vassilevskiy and
Karakulin 1950, Esfandiari 1951, Chupp 1954, Vimba
1970, Şvartsman et al. 1975, Deighton 1976, Ellis and Ellis
1987, Braun 1995, 1998, Braun and Melnik 1997, Braun
and Crous 2005, Bakalova and Borisova 2010, Pirnia et al.
2010, Bensch et al. 2012, Crous et al. 2013, Świderska-
Burek 2015, Heydari et al. 2017).
For scanning electron microscopy (SEM), infected leaves
bearing conidiophores and/or conidia were mounted on
stubs with double-sided tapes. They were coated with
gold in Polaron SC 502 Sputter Coater and examined with
Jeol JSM 6060 SEM at 5‒10 kV in the Gazi University,
Faculty of Science.
RESULTS AND DISCUSSION
During our study in Yedigöller National Park on
determining the microfungi on vascular plants, we
collected several phytopathogenic hyphomycetes species
that cause foliar spots. Some of the microfungus species
determined in this study, such as Cercospora datiscicola
Esfand, Cercospora mercurialis Pass., Filiella pastinacae
(P. Karst.) Videira & Crous, Pseudocercospora
sambucigena U. Braun, Crous & K. Schub., Ramularia
linaria Baudyš & Picb. and Ramularia sphaeroidea Sacc.,
were the first records for Türkiye. The list of microfungi
with their descriptions (for new records only), host plants,
localities, habitats, collection dates, and voucher
numbers were presented below according to the
systematics given in Index Fungorum (Kirk 2023).

This fungus was reported in Armenia (Braun and Melnik
1997, Crous and Braun 2003), and Iran (Esfandiari 1951,
Chupp 1953). Although the specimen of Cercospora
datiscicola collected from Yedigöller area is
morphologically similar to descriptions made by Braun
and Melnik (1997), Esfandiari (1951), and Chupp (1953),
it differed slightly, especially in terms of conidia size and
number of septa: 30–100 × 4–5 μm and (2)3–7(9) septate
(Braun and Melnik 1997); 3285 × 4–5 μm and 2–7 rarely
89 septate (Esfandiari 1951); 30–90 × 4–5 μm and 2–9

described conidia measuring 7–15 (18) × (5) 6–12.5 μm and
conidiophores measuring (15) 30–100 (150) × (2.5) 3–6 (7)
μm; and Ellis and Ellis (1987) described conidia measuring
8–12 μm diameter and conidiophores measuring 40–120 × 3
μm.

Fungi associated with leaf spot symptoms of plants in forest areas of Golestan province, Iran, were collected and examined based on morphological characteristics of conidiophores, conidia and conidiogenous loci. Ten taxa were identified. Among the taxa, Passalora cf. bacilligera and Pseudocladosporium hachijoens are new records for the mycobiota of Iran. Cercospora on Eruca sp. was morphologically different from other Cercospora hitherto been reported on Brassicaceae and compared with Cercospora species on this plant family. Cercospora pantoleuca was newly reported from Golestan province (North of Iran). Furthermore, Plantago major and Sambucus nigra were found to be new hosts for Cercospora pantoleuca and Ramularia sambucina in Iran, respectively.

Ramularia is a species-rich genus that harbours plant pathogens responsible for yield losses to many important crops, including barley, sugar beet and strawberry. Species of Ramularia are hyphomycetes with hyaline conidiophores and conidia with distinct, thickened, darkened, refractive conidiogenous loci and conidial hila, and Mycosphaerella sexual morphs. Because of its simple morphology and general lack of DNA data in public databases, several allied genera are frequently confused with Ramularia. In order to improve the delimitation of Ramularia from allied genera and the circumscription of species within the genus Ramularia, a polyphasic approach based on multilocus DNA sequences, morphological and cultural data were used in this study. A total of 420 isolates belonging to Ramularia and allied genera was targeted for the amplification and sequencing of six partial genes. Although Ramularia and Ramulariopsis proved to be monophyletic, Cercosporella and Pseudocercosporella were polyphyletic. Phacellium isolates clustered within the Ramularia clade and the genus is thus tentatively reduced to synonymy under Ramularia. Cercosporella and Pseudocercosporella isolates that were not congeneric with the ex-type strains of the type species of those genera were assigned to existing genera or to the newly introduced genera Teratoramularia and Xenoramularia, respectively. Teratoramularia is a genus with ramularia-like morphology belonging to the Teratosphaeriaceae, and Xenoramularia was introduced to accommodate hyphomycetous species closely related to Zymoseptoria. The genera Apseudocercosporella, Epicoleosporium, Filiella, Fusidiella, Neopseudocercosporella, and Mycosphaerelloides were also newly introduced to accommodate species non-congeneric with their purported types. A total of nine new combinations and 24 new species were introduced in this study.

The present paper is a continuation of a series of comprehensive taxonomic treatments of cercosporoid fungi (formerly Cercospora s. lat.), belonging to Mycosphaerellaceae (Ascomycota). This fifth contribution of this series proceeds with treatments of cercosporoid fungi on dicots and comprises species occurring on hosts belonging to the families Anacardiaceae and Annonaceae, which are described and illustrated in alphabetical order under the particular cercosporoid genera, supplemented by keys to the species concerned. A detailed introduction, a survey of currently recognised cercosporoid genera, a key to the genera concerned, and a discussion of taxonomically relevant characters were published in the first part of this series. The following taxonomic novelties are introduced: Passalora cotini sp. nov., P. guoana nom. nov., P. rhois-aromaticae sp. nov., and Pseudocercospora rhoicola.

The paper presents characteristics of cercosporoid fungal species from three genera, Cercospora, Passalora, and Pseudocercospora, occurring in Poland and deposited in Polish herbaria or to be expected due to the occurrence of their host plants in the Polish flora. The physiographic literature, but primarily own collections, as well as those gathered in the national herbaria, were the object of the revision. This monograph provides morphological descriptions, lists of hosts and distribution in Poland and worldwide as well as detailed illustrations for 41 species. Dichotomous keys for identification of fungi parasitizing hosts from different plant families were prepared within the individual fungal genera. The present study represents a compilation of 115 cercosporoid species, of which 63 are reported from Poland and another 6 were doubtful and excluded. The fungi parasitize 221 taxa of host plants from 131 genera and 47 families, out of which 158 taxa from 94 genera and 29 families have been actually found in Poland. Fourteen species described in this book belong to Cercospora apii s. l. Nine quarantine species are listed, from which only three have been published so far. This study will be helpful to mycologists, plant pathologist, and Polish plant protection services for identification purposes of the fungi concerned.
