Te Lipetsk region is an area of the forest-steppe zone, which has a rather long history of mycobiota studies primarily devoted to diversity and phenology of macromycetes [6–12]. Moreover, the purposeful research of aphyllophoroid fungi has been recently initiated in this region [13]. To date, the mycobiota of the region Published by Polish Botanical Society 1 of 15 Volobuev et al. / Aphyllophoroid fungi in forest-steppe communities of the Lipetsk region includes 204 species of aphyllophoroid basidiomycetes, of which 14 species are listed in the regional Red data book [14]. Te aim of our study was to widen knowledge on the species diversity and substrate preferences of aphyllophoroid basidiomycetes in forest-steppe communities of the Lipetsk region. Because most of the territory of the Lipetsk region has been disturbed over the last century, natural forest-steppe communities have been preserved only as local fragments with nature conservation status. Most of these fragments are included in the Galichya Gora Nature Reserve, which is the core of a network of regional protected areas. It occupies an area of 2.3 km2 and consists of six separate parts (Fig. 1). Fig. 1 Te locations of territories surveyed. (A) Lipetsk region, Russia. (B) Areas studied: 1 – Mo- rozova Gora protected area; 2 – Plyushchan protected area; 3 – Te Oleniy Nature Park; 4 – Voronov Kamen protected area; 5 – Vorgolskoye protected area. Te landscape of the territory is quite heterogeneous. It includes upland steppe and forest zones based on Devonian limestone outcrops (Fig. 2, Fig. 3), rugged by the Bystraya Sosna River valley, its feeders and gullies, and partially by the Don River valley. Te reserve is covered with deciduous forest communities formed by Quercus robur, Tilia cordata, and Acer platanoides as dominant species with Betula pendula and Populus tremula as primary species, and undergrowth, which are typical for the Central Russian Upland [15]. Besides the Galichya Gora Nature Reserve, the Oleniy Nature Park was explored and should be mentioned as one of the largest and youngest protected areas in the Lipetsk region. Material and methods Our results are based on feld trips to a number of protected areas in the Lipetsk region with forest-steppe vegetation in the Galichya Gora Nature Reserve and the Oleniy Nature Park in September 2016. Material was collected from fve areas according to the classical route method (Fig. 1). © The Author(s) 2018 Published by Polish Botanical Society Acta Mycol 53(2):1112 2 of 15 Volobuev et al. / Aphyllophoroid fungi in forest-steppe communities of the Lipetsk region Fig. 2 Dead foor maple forest with lime trees in the Voronov Kamen protected area. Photo by S. Volobuev. Te Morozova Gora protected area is located on the east side of the Don River valley and covers approximately 3 km2. Te major part of it is a plain (600 m at its widest), which becomes narrower and forms a valley while going from the north to the south. Te vegetation comprises fragments of upland oak and birch forests, foodplain willow forests, meadows, and stipe-herb steppe fragments. Te Plyushchan protected area was originally a forest plot on the west side of the Don River valley, rugged by the twisting Plyushchan River from the south to the east, which surrounds the limestone-clif valley sides. Te vegetation cover mostly consists of oak and birch forests, foodplain willow forests, herb-rich steppe fragments, and pine plantings. Two areas – the Voronov Kamen and the Vorgolskoye – lie on the right side of the Vorgol River. Its valley has a canyon-like appearance and limestone-clif outcrops are quite usual along the riverside. Te typical vegetation cover types for these areas are upland lime tree and oak forests and fragments of foodplain willow forests [10]. Te Oleniy Nature Park is protected separately from the Galichya Gora Reserve and is located near the villages of Nikolskoye and Sukhodol in the Krasninskiy District of the Lipetsk region. It covers over 12 km2 and most of the territory is occupied by agricultural land, interlaced with gullies and ravines, where diferent meadow and steppe associations have formed. In addition, ravine oak and birch forests, blackthorn bushes, and shelter belts are widely represented. Some admixtures of garden trees are also found [10]. © The Author(s) 2018 Published by Polish Botanical Society Acta Mycol 53(2):1112 3 of 15 Volobuev et al. / Aphyllophoroid fungi in forest-steppe communities of the Lipetsk region Fig. 3 Limestone-clif outcrops on the bank of the Vorgol River.

Thus, the objective of this study was to secure resources for the wood decay fungi in Korea. We investigated wood decay fungi in Yeoninsan Provincial Park, Korea, and the collected specimens were identified based on ITS sequence analysis. Two species were unrecorded species in Korea: Postia hirsuta (Polyporales, Basidiomycota) and Hyphodontia reticulata (Hymenochaetales, Basidiomycota). Another species was previously reported without detailed description: Ceriporia alachuana (Polyporales, Basidiomycota). Here, we provided additional detailed microscopic features and phylogenetic analysis of these species.

Sibounnavong, P., Cynthia, C.D., Kalaw, S.P., Reyes, R.G. and Soytong, K. (2008). Some species of macrofungi at Puncan, Carranglan, Nueva Ecija in the Philippines. Journal of Agricultural Technology 4(2): 105-115. Mushrooms and macrofungi were collected at Puncan, Carranglan, Nueva Ecija, Philippines in during dry season. There were identified into 7 species. With this, one species belong to Order Tulasnellales or Tremellales (Jelly Fungi), Family Auriculariaceae which is Auricularia fuscosuccinea. Another 4 species belong to Order Polyporales; Family Polyporaceae which are Gloeoporus dichrous (Fr.) Bres, Coltricia perennis (Fr.) Murr, Trametes versicolor (L.: Fries) Pilt and Phellinus pini (Fr.) Ames. Out of these, 2 species belong to Order Agaricales (Mushroom); Family Tricholomataceae which is Hobenbuebelia petaloides (Bull ex Fr.) Schulz and Family Cantharellaceae which is Cantharellus minor Pk. It is noticed that our survey were done in dry season, high temperature and low humidity which found that the climate and whether are not favorable for mushroom and other fungi growing. Since then, it is indicated that the species found in this season are rarely fresh but their specimens mostly dried. Key words: Auricularia, Gloeoporus, Coltricia, Trametes, Phellinus, Hobenbuebelia, Cantharellus Introduction Mushrooms and macrofungi need moisture to develop. There is an optimum period of mushroom season when the most of mushrooms and macro fungi come to appear.

  • 9B Taxonomy to Genus
    Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org.

  • A Checklist of Clavarioid Fungi (Agaricomycetes) Recorded in Brazil
    A checklist of clavarioid fungi (Agaricomycetes) recorded in Brazil ANGELINA DE MEIRAS-OTTONI*, LIDIA SILVA ARAUJO-NETA & TATIANA BAPTISTA GIBERTONI Departamento de Micologia, Universidade Federal de Pernambuco, Av. Nelson Chaves s/n, Recife 50670-420 Brazil *CORRESPONDENCE TO: [email protected] ABSTRACT — Based on an intensive search of literature about clavarioid fungi (Agaricomycetes: Basidiomycota) in Brazil and revision of material deposited in Herbaria PACA and URM, a list of 195 taxa was compiled. These are distributed into six orders (Agaricales, Cantharellales, Gomphales, Hymenochaetales, Polyporales and Russulales) and 12 families (Aphelariaceae, Auriscalpiaceae, Clavariaceae, Clavulinaceae, Gomphaceae, Hymenochaetaceae, Lachnocladiaceae, Lentariaceae, Lepidostromataceae, Physalacriaceae, Pterulaceae, and Typhulaceae). Among the 22 Brazilian states with occurrence of clavarioid fungi, Rio Grande do Sul, Paraná and Amazonas have the higher number of species, but most of them are represented by a single record, which reinforces the need of more inventories and taxonomic studies about the group. KEY WORDS — diversity, taxonomy, tropical forest Introduction The clavarioid fungi are a polyphyletic group, characterized by coralloid, simple or branched basidiomata, with variable color and consistency. They include 30 genera with about 800 species, distributed in Agaricales, Cantharellales, Gomphales, Hymenochaetales, Polyporales and Russulales (Corner 1970; Petersen 1988; Kirk et al. 2008). These fungi are usually humicolous or lignicolous, but some can be symbionts – ectomycorrhizal, lichens or pathogens, being found in temperate, subtropical and tropical forests (Corner 1950, 1970; Petersen 1988; Nelsen et al. 2007; Henkel et al. 2012). Some species are edible, while some are poisonous (Toledo & Petersen 1989; Henkel et al. 2005, 2011). Studies about clavarioid fungi in Brazil are still scarce (Fidalgo & Fidalgo 1970; Rick 1959; De Lamônica-Freire 1979; Sulzbacher et al.

    Karstenia 20: 1-15. 1980 On Fennoscandian polypores 7. The genus Pycnoporellus TUOMO NIEMELA NIEMELA, T. 1980: On Fennoscandian polypores 7. The genus Pycnoporellus. - Karstenia 20: 1-15. Descriptions are given of the two species of Pycnoporellus occurring in Fennoscandia, P. alboluteus (Ell. & Ev.) Kotl. & Pouz. and P. fulgens (Fr.) Donk. Their distributions in North Europe are mapped, and their world distributions reviewed. Their ecology, phenology, host relationships, and cultural and microscopical characters are discussed. Great variability exists in the microscopical characters of both species. P. alboluteus is very rare in North Europe, where it has been recorded from only two localities in northern Finland, on Picea abies and once on Alnus incana. P. fulgens is rare and south-eastern in distribution, being known from four Swedish localities and several localities in southern Finland and the adjacent U.S.S.R., mostly on Picea abies, but also on Pinus sylvestris, Populus tremula and Betula. Study of the types indicates that the names frpex woronowii Bres. and Lenzites sepiaria var. dentifera Peck are synonymous with P. alboluteus, and that Ochroporus lithuanicus BYonski (type selected), Polyporus aurantiacus Peck and P. fibrillosus Karst. are synonymous with P. fulgens. The taxonomic position of the genus Pycnopore/lus is discussed. Tuomo Niemela, Department of Botany, University of Helsinki, Unioninkatu 44, SF - 00170 Helsinki 17, Finland.

  • Medicinal Potential of Mycelium and Fruiting Bodies of an Arboreal
    www.nature.com/scientificreports OPEN Medicinal potential of mycelium and fruiting bodies of an arboreal mushroom Fomitopsis ofcinalis in therapy of lifestyle diseases Agata Fijałkowska1, Bożena Muszyńska1*, Katarzyna Sułkowska‑Ziaja1, Katarzyna Kała1, Anna Pawlik2, Dawid Stefaniuk2, Anna Matuszewska2, Kamil Piska3, Elżbieta Pękala3, Piotr Kaczmarczyk4, Jacek Piętka5 & Magdalena Jaszek2 Fomitopsis ofcinalis is a medicinal mushroom used in traditional European eighteenth and nineteenth century folk medicine. Fruiting bodies of F. ofcinalis were collected from the natural environment of Świętokrzyskie Province with the consent of the General Director for Environmental Protection in Warsaw. Mycelial cultures were obtained from fragments of F. ofcinalis fruiting bodies. The taxonomic position of the mushroom mycelium was confrmed using the PCR method. The presence of organic compounds was determined by HPLC–DAD analysis. Bioelements were determined by AF‑AAS. The biochemical composition of the tested mushroom material was confrmed with the FTIR method. Antioxidant properties were determined using the DPPH method, and the antiproliferative activity was assessed with the use of the MTT test. The presence of indole compounds (l‑tryptophan, 6‑methyl‑d,l‑tryptophan, melatonin, 5‑hydroxy‑l‑tryptophan), phenolic compounds (p‑hydroxybenzoic acid, gallic acid, catechin, phenylalanine), and sterols (ergosterol, ergosterol peroxide) as well as trace elements was confrmed in the mycelium and fruiting bodies of F. ofcinalis. Importantly, a high level of 5‑hydroxy‑l‑tryptophan in in vitro mycelium cultures (517.99 mg/100 g d.w) was recorded for the frst time. The tested mushroom extracts also showed antioxidant and antiproliferative efects on the A549 lung cancer cell line, the DU145 prostate cancer cell line, and the A375 melanoma cell line.

  • Piptoporus Betulinus, Fomitopsis Betulina)
    Birch Fungi – Razor Strop, Birch Bracket (Piptoporus betulinus, Fomitopsis betulina) Features - This distinctive fungus only grows on birches, looks like nothing else that grows on birches, and is very common. It is not an aggressive tree killer, but is instead primarily in the business of decomposing dead trees. Birch polypore is present throughout the range of the birches, which grow around the globe in the northern hemisphere. The white-to-brownish fruiting bodies are annual, emerging from the bark of birches in spring and summer, but they deteriorate slowly and are still visible through the winter, though by then they have blackened and are not so attractive. Global Uses – Otzi the Iceman, who lived 5300 years ago, carried two fragments of a fruiting body of Fomitopsis betulina (formerly Piptoporus betulinus). Some scientists believe that Ӧtzi might have used the fungus for medical purposes and, although the idea arouses some controversy, the long tradition of the use of F. betulina in folk medicine is a fact. Infusion from F. betulina fruiting bodies was popular, especially in Russia, Baltic countries, Hungary, Romania for its nutritional and calming properties. Fungal tea was used against various cancer types, as an immunoenhancing, anti-parasitic agent, and a remedy for gastrointestinal disorders. Antiseptic and anti-bleeding dressings made from fresh F. betulina fruiting body were applied to wounds and the powder obtained from dried ones was used as a painkiller. Was used as a razor strop to sharpen fine edged blades. Medicinal Potential – Chemical Constituents: A and C, 1,3-beta-D-glucopyranan, B ergosta-7,22-dien-3- ol, fungisterol, ergosterol, agaric acid, dehydrotumulosic acid, ungalinic acid, betulinic acid, and tumulosic acid.
