Introduction
Turkey has a very diverse flora, and the higher plants have been well studied. However, the
mycobiota has not been extensively investigated and most studies deal with macromycetes
especially agaricoid fungi. During the past two decades research on micromycetes (including
hyphomycetes) in the country has intensified (Hüseyinov & Selçuk 1999, Braun et al. 2000,
Hüseyin & Selçuk 2001, Hüseyin et al. 2003, 2005, Mel’nik et al. 2004, Selçuk et al. 2009, 2010,
2014). A new hyphomycete species was found during a trip to Kervansaray Mountain, Kırşehir
Province, Central Anatolian Peninsula. This mountain lies in the Irano-Turanian phytogeographic
region (Hamzaoğlu 1996). The fungus belongs to the genus Manoharachariella, which was
described by Bagyanarayana et al. (2009). They described the type species, M. lignicola, on an
unidentified dead twig from Visakhapatnam, Andhra Pradesh, India. A second species was
described as M. indica by Rajeshkumar & Singh (2012).
Materials & Methods
Samples were collected during a mycological excursion to the Kervansaray Mountain in
Boztepe District, Kırşehir Province of Turkey in 2012. Dead twigs were observed and
photographed using an Olympus SZX 16 binocular stereomicroscope with an Olympus DP26 Digi-
CAM camera. The collections were examined in distilled water and for microphotographs a Leica
DM 3000 (Axio imager 2 equipped with Nomarski differential interference contrast optics)
microscope was used. Identification was carried out through comparison with current taxonomic
works of hyphomycetous fungi under consideration. The examined specimen is deposited at the
Ahi Evran University, Arts and Sciences Faculty, Department of Biology, in Kırşehir Province of
Turkey.

Discussion
The genus Manoharachariella Bagyan., N.K. Raj & Kunwar and its type species M.
lignicola Bagyan., N.K. Raj & Kunwar was described from Andhra Pradesh, India (Bagyanarayana
et al. 2009). Rajeshkumar & Singh (2012) described a second species, M. indica Rajeshkumar &
S.K. Singh from eastern Ghats, India. Conidia of M. lignicola are doliiform, obpyriform,
ellipsoidal, apiculate, dictyoseptate, smooth, tiered, 42.5–50.5 × 25–32 µm with several
longitudinal septa (Bagyanarayana et al. 2009). Conidia of M. indica are doliiform, obpyriform,
ellipsoidal or irregular, apiculate, dictyoseptate, 84–110(–120) × 31–44 µm with 10–13
longitudinal septa (Rajeshkumar & Singh 2012).
Manoharachariella elsadii differs from M. lignicola and M. indica by smaller conidia, number of
conidial septa, and size of conidiophores.

Refined families of Dothideomycetes: orders and families incertae sedis in Dothideomycetes
Article
Full-text available
  • Dec 2020
  • FUNGAL DIVERS
Numerous new taxa and classifications of Dothideomycetes have been published following the last monograph of families of Dothideomycetes in 2013. A recent publication by Honsanan et al. in 2020 expanded information of families in Dothideomycetidae and Pleosporomycetidae with modern classifications. In this paper, we provide a refined updated document on orders and families incertae sedis of Dothideomycetes. Each family is provided with an updated description, notes, including figures to represent the morphology, a list of accepted genera, and economic and ecological significances. We also provide phylogenetic trees for each order. In this study, 31 orders which consist 50 families are assigned as orders incertae sedis in Dothideomycetes, and 41 families are treated as families incertae sedis due to lack of molecular or morphological evidence. The new order, Catinellales, and four new families, Catinellaceae, Morenoinaceae Neobuelliellaceae and Thyrinulaceae are introduced. Seven genera (Neobuelliella, Pseudomicrothyrium, Flagellostrigula, Swinscowia, Macroconstrictolumina, Pseudobogoriella, and Schummia) are introduced. Seven new species (Acrospermum urticae, Bogoriella complexoluminata, Dothiorella ostryae, Dyfrolomyces distoseptatus, Macroconstrictolumina megalateralis, Patellaria microspora, and Pseudomicrothyrium thailandicum) are introduced base on morphology and phylogeny, together with two new records/reports and five new collections from different families. Ninety new combinations are also provided in this paper.

Microfungi on Tectona grandis (teak) in Northern Thailand
Article
  • May 2016
To date there is virtually no information available concerning the fungi associated with Tectona grandis (teak) (Lamiaceae) in Thailand. In this study, samples of microfungi were collected from both asymptomatic stems and dead wood, and symptomatic branches, stem and leaves of T. grandis from 27 sites in six provinces (Chiang Mai, Chiang Rai, Phayao, Phitsanulok, Phrae and Uttaradit Provinces). Morphology and combined multi-gene phylogeny (CAL, GAPDH, ITS, LSU, RPB2, SSU, TEF1 and TUB) were used to identify taxa. A total of 270 collections, representing 28 fungal species residing in 12 families, 7 orders and 21 genera, with three species of uncertain taxonomic placement were identified. Of these, one family, three genera and 14 species are new to science. The new family, Pseudocoleodictyosporaceae is introduced based on its distinct lineage in the Dothideomycetes and its unique morphology as compared to Roussoellaceae and Torulaceae. The new genera are Neooccultibambusa, Pseudocoleodictyospora and Subglobosporium. The newly described species are Diaporthe neoraonikayaporum, D. tectonendophytica, D. tectonae, D. tectonigena, Hermatomyces tectonae, H. thailandica, Manoharachariella tectonae, Neooccultibambusa chiangraiensis, Pseudocoleodictyospora sukhothaiensis, Ps. tectonae, Ps. thailandica, Rhytidhysteron tectonae, Subglobosporium tectonae and Tubeufia tectonae. Fourteen species are known published taxa including Alternaria tillandsiae, Berkleasmium talaumae, Boerlagiomyces macrospora, Ceratocladium purpureogriseum, Fusarium solani, Helicoma siamense, Lasiodiplodia theobromae, Macrovalsaria megalospora, Paradictyoarthrinium diffractum, Phaeoacremonium italicum, Sphaeropsis eucalypticola, Stachybotrys levispora, St. renispora and Thaxteriellopsis lignicola. Epitypifications or reference specimens are designated for Boerlagiomyces macrospora and Macrovalsaria megalospora. Macrovalsaria megalospora is transferred from Botryosphaeriaceae to Dothideomycetes genus, incertae sedis based on taxonomy and phylogenetic analysis, which indicate it is distinct from Botryosphaeriaceae. All fungal species represent first reports on T. grandis in Thailand. New taxa and taxa incertae sedis, as well as known taxa which are established as reference specimens or epitypes, are presented with phylogenetic tree analyses, habitat, known distribution, material examined, full descriptions, notes and figures. Information is also provided for known taxa to add to the body of knowledge and to assist those wishing to study fungi occurring on T. grandis in future.

Hyphomycetous fungi in several forest ecosystems of Black sea provinces of Turkey
Article
Full-text available
  • Apr 2014
Hyphomycetous specimens were collected in forest ecosystems of the middle and east Black Sea coastal region. Sixty-nine taxa in 50 genera were recorded on various substrates including 20 plant families. Volutella were the common fungal genera. Fagaceae, Betulaceae, Buxaceae, Ulmaceae and Pinaceae are common host plant families. Introduction Hyphomycetes make up the majority of what are commonly called moulds, and some are regarded as the weeds of the fungal kingdom. In addition to growing on many natural substrates such as plant tissues, wood and bark, dung, insects and other arthropods, and other fungi including lichens, and in a diversity of ecological habitats, moulds are involved in food spoilage, contaminate many manufactured materials such as wood, paper and textiles, and are frequent visitors to the human indoor environment (Seifert et al. 2011). Hyphomycetous fungi comprise more than 1800 genera and 9000 worldwide species (Kirk et al. 2008). Hyphomycetes are a group of conidial fungi characterized by the formation of asexual spores (conidia) on conidiophores that are not contained in a fruiting body; i.e., without acrevuli or pycnidia, although some form sporodochia and synnemata (Ulloa & Hanlin 2012). The flora of Turkey is very diverse (about 10500 species and subspecies belonging to 1233 genera and 173 families) and many studies have been carried out dealing with higher plants. However, the mycobiota is insufficiently investigated, except for macromycetes (generally Agaricoid fungi). Turkey is characterised by high diversity of woody plants. It is rich in the Pyrus, Crataegus, Prunus, Cerasus and Amygdalus species and other members of Rosaceae, which are source of genetic diversity of most industrial fruit trees. Turkey's higher plants have been very well studied, whereas the mycobiota has not been extensively investigated and most studies on the fungi have dealt with macromycetes. Some information concerning micromycetes growing on higher plants was provided by Bremer et al. (1947, 1948, 1952). The list of plant diseases occuring in Turkey, including those caused by hyphomycetes, was provided by Karel (1958). Studies on Mycosphere 5 (2): 334–344 (2014) ISSN 2077 7019
