Karadelev2 THE FIRST RECORD OF VELUTICEPS BERKELEYI (BASIDIOMYCETES) IN THE MEDITERRANEAN ДОГАНХ.Х., КАРАДЕЛЕВМ. ПЕРВАЯ НАХОДКА VELUTICEPS BERKELEYI (BASIDIOMYCETES) Â СРЕДИЗЕМНОМОРЬЕ The genus Veluticeps (Cooke) Pat. is a striking and distinctive group of wood-decay fun- gi that is associated with brown-rotted wood. Previously, Hjortstam et Tellerнa (1990) ex- panded the concept of Veluticeps to include Columnocystis Pouzar. Nakasone (1990) accep- ted these as synonymous and presents seven species descriptions. Later, Nakasone (2004) worked on a revision of the current status of Veluticeps in the world, and as a result of this work a key to the accepted species of Veluticeps and related taxa was provided. She transfer- red some species such as Veluticeps philippinensis Bres., V. tabacina (Cooke) Burt and V. heimii Malenзon to the genus Pileodon, whereas Campylomyces and only eight species remained in Veluticeps. Currently, the genus Veluticeps includes two groups based on the presence or absence of hyphal pegs. Veluticeps sensu stricto is limited by taxa with hyphal pegs, namely, V. berkeleyi and V. australiensis. Veluticeps sensu lato essentially equivalent to the former genus Columnocystis includes taxa that lack hyphal pegs, namely, Veluticeps abietina (Pers.) Hjortstam et Tellerнa, V. africana (Boidin, Lanq. et Gilles) Hjortstam et Tel- lerнa, V. ambigua (Peck) Hjortstam et Tellerнa, V. fimbriata (Ellis et Everh.) Nakasone, V. fusispora (G. Cunn.) Hjortstam et Ryvarden and V. pimeriensis (Gilbertson) Hjortstam et Tellerнa. Most of the species from the genus have a restricted geographical range and are qu- ite rare except for V. berkeleyi which has a wider distribution. Nevertheless, there is no data for the occurrence of V. berkeleyi in the Mediterranean. V. berkeleyi is widespread in Arizona and causes a brown cubical heartrot on Ponderosa pine. This fungus does not fruit on living trees, but its basidiocarps develop abundantly on stumps and logs on the ground (Gilbertson, 1974). According to Nakasone (1990), the spe- cies is distributed in western United States of America, Mexico, Cuba, Guatemala, Taiwan, and Japan. In Northern and Central America the species is found on pine trees, especially on Pinus ponderosa while in Taiwan and Japan it is associated with a brown cubical rot of yel- low cypress (Chamaecyparis obtusa var. formosana). The species Veluticeps pini Pat. from Indochina is conspecific with V. berkeleyi (Nakasone, 2004). The cultural morphology of V. berkeleyi is described by Gilbertson et al. (1968). Martin and Gilbertson (1973) reported that V. berkeleyi has a tetrapolar (or bifactorial) incompatibility system. The materials were collected during the implementation of the bilateral project (2002—2005) between the Institute of Biology, the Faculty of Natural Science and Mathe- 1 Biology Department, Science Faculty, Selзuk University, 42031 Campus / Konya, Turkey.

In Turkey, the materials were collected in October 2003 on a stump of Juniperus excelsa M. Bieb. and in May 2005 on a stump of J. foetidissima Willd. that are new hosts of the fun- gus (Fig. 1). Thin, freehand sections of basidiocarps were mounted in 3 % KOH and Melzer’s rea- gent and examined with light microscope «Olympus». Identification was made by referring to Nakasone’s key (Nakasone, 2004). Part of the collection was forwarded to Dr. Karen Na- kasone for a critical review and confirmation. All the material is stored at mycocollections: Mushroom Application and Research Cen- tre of Selзuk University, Turkey and Macedonian National Collection at the Institute of Bio- logy, Faculty of Natural Science and Mathematics, Republic of Macedonia. The obtained data were incorporated into the databases (KONYA and MACFUNGI). The author name of the taxon was checked according to Kirk, Ansell (1992) and http://www.indexfungorum.org/Names/Names.asp.

Bot. 10 (46) : 333, 1868; Veluticeps fusca C. J. Humphrey et Long, Ann. Mo. bot. Gdn 13 (3) : 329, 1926. Basidiocarps perennial, up to 15 Ч 5 cm, effused-reflexed to resupinate, up to 3 mm thick (Fig. 2). Hymenial surface brownish, appearing finely hydnaceous from abundant ste- rile hyphal fascicles (Fig. 3), sometimes deeply cracked, black in KOH. Hyphal pegs pre- sent as aggregation of tramal cystidia projecting up to 100 mkm beyond hymenium, up to 7 mkm diam., originating in the subicular-subhymenial interface. Tramal cystidia long cla- vate to cylindrical, up to 250 Ч 8—9 mkm, tapering to 2—3.5 mkm diam. at the base, with a basal clamp, sometimes with secondary septa, apex obtuse and rounded or slightly tapering, 382 Fig. 2. Basidiocarp of Veluticeps berkeleyi. brownish yellow to dark brown throughout, often encrusted with colourless, granular crys- tals or with brownish yellow mucilaginous or resinous materials (Fig. 4). Context brown, fibrous. Hyphal system monomitic although appearing dimitic, with nodose-septate gene- rative and sclerified hyphae. Sclerified hyphae 2—4 mkm diam. with rare clamp connec- tions, rarely branched, walls thick, light to dark brown, smooth. Basidia narrowly clavate, 4-sterigmate, 65—100 Ч 7—8 mkm, gradually tapering, with a basal clamp connection, walls thin, light brown, smooth, sterigmata usually collapsed. Basidiospores cylindrical, hyaline, smooth, 10.6—11 Ч (2.2)3.3—4 mkm, Melzer’s negative, acyanophilous (Fig. 5). The hyphal system of Veluticeps is subject to different interpretations. It has been desc- ribed as dimitic, composed of generative hyphae and thick-walled skeletal hyphae (Welden, Fig. 3. Finely hydnaceous hyphal fascicles of Veluticeps berkeleyi. 383 Fig. 4.

Ecological status.Thematerial was collected on a stump of J. excelsa from Mer- sin-Arslankцy district, situated in the southern Mediterranean part of Turkey. The forest ma- inly consists of Cedrus libani A. Rich. mixed with Abies cilicica (Ant. et Kotschy) Carr. subsp. isaurica Coode et Cullen and J. foetidissima, but in some places, there is pure Juniper forest (J. excelsa and J. foetidissima). In second locality, the material was collected on a stump of J. foetidissima in Ankara-Nallihan Karageyis Mountain, Bakacak district, situated in the west northern part of Turkey. The forest consists of pure J. excelsa and J. foetidissima (Fig. 1). Fig. 5.

  • 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.

Current Research in Environmental & Applied Mycology (Journal of Fungal Biology) 7(3), 187–192, Doi 10.5943/cream/7/3/5 Abstract Deviant form of wood-decaying basidiomycete Neolentinus lepideus was found in western Siberia, the rare sterile form N. lepideus f. ceratoides was found in the Novosibirsk Region. The description and an illustration of taxon is provided. The sterile form does not produce a hymenophore. It is formed under conditions of darkness on wood constructions in caves, grottos, mines, cellars, basements and under the floor. Sterile bodies of the fungus of horn appearance have a clavarioid morphotype. They are coral-like branched, with elongated rounded sprouts extending from the common trunk, which under normal conditions would have given a stipe. The caps with lamellar hymenophore, which would appear on normal fruiting bodies, are completely absent. Monstrose forms in Neolentinus species represents morphological modifications of fruiting bodies, associated with disturbance of normal morphogenesis under dark or shady conditions.

Sweet sorghum is a promising crop for a warming, drying African climate, and basic information is lacking on conversion pathways for its lignocellulosic residues (bagasse). Brown rot wood-decomposer fungi use carbohydrate-selective pathways that, when assessed on sorghum, a grass substrate, can yield information relevant to both plant biomass conversion and fungal biology. In testing sorghum decomposition by brown rot fungi (Gloeophyllum trabeum, Serpula lacrymans), we found that G. trabeum readily degraded sorghum, removing xylan prior to removing glucan. Serpula lacrymans, conversely, caused little decomposition.

  • Genera of Corticioid Fungi: Keys, Nomenclature and Taxonomy Article
    Studies in Fungi 5(1): 125–309 (2020) www.studiesinfungi.org ISSN 2465-4973 Article Doi 10.5943/sif/5/1/12 Genera of corticioid fungi: keys, nomenclature and taxonomy Gorjón SP BIOCONS – Department of Botany and Plant Physiology, University of Salamanca, 37007 Salamanca, Spain Gorjón SP 2020 – Genera of corticioid fungi: keys, nomenclature, and taxonomy. Studies in Fungi 5(1), 125–309, Doi 10.5943/sif/5/1/12 Abstract A review of the worldwide corticioid homobasidiomycetes genera is presented. A total of 620 genera are considered with comments on their taxonomy and nomenclature. Of them, about 420 are accepted and keyed out, described in detail with remarks on their taxonomy and systematics. Key words – Corticiaceae – Crust fungi – Diversity – Homobasidiomycetes Introduction Corticioid fungi are a diverse and heterogeneous group of fungi mainly referred to basidiomycete fungi in which basidiomes are generally resupinate. Basidiome construction is often simple, and in most cases, only generative hyphae are found. In more structured basidiomes, those with a reflexed margin or with a pileate surface, more or less sclerified hyphae are usually found. Even the basidiome structure is apparently not very complex, hymenophore configuration should be highly variable finding smooth surfaces or different variations to increase the spore production area such as rugose, tuberculate, aculeate, merulioid, folded, or poroid hymenial surfaces. It is often thought that corticioid fungi produce unattractive and little variable forms and, in most cases, they go unnoticed by most mycologists as ungraceful forms that ‘cover sticks and look like a paint stain’. Although the macroscopic variability compared to other fungi is, but not always, usually limited, under the microscope they surprise with a great diversity of forms of basidia, cystidia, spores and other microscopic elements (Hjortstam et al.

Biodiversity Data Journal 8: e51459. https://doi.org/10.3897/BDJ.8.e51459 Abstract Background Human activities are allowing the ever-increasing dispersal of taxa to beyond their native ranges. Understanding the patterns and implications of these distributional changes requires comprehensive information on the geography of introduced species. Current knowledge about the alien distribution of macrofungi is limited taxonomically and temporally, which severely hinders the study of human-mediated distribution changes for this taxonomic group.
