ПЕРВАЯ НАХОДКА VELUTICEPS BERKELEYI (BASIDIOMYCETES) В СРЕДИЗЕМНОМОРЬЕ The genus Veluticeps (Cooke) Pat. is a striking and distinctive group of wood-decay fungi that is associated with brown-rotted wood. Previously, Hjortstam et Tellerнa (1990) ex- panded the concept of Veluticeps to include Columnocystis Pouzar. Nakasone (1990) accepted 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 species 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 yellow 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- 1Biology 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 fungus (Fig. 1). Thin, freehand sections of basidiocarps were mounted in 3 % KOH and Melzer’s reagent 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 Nakasone for a critical review and confirmation. All the material is stored at mycocollections: Mushroom Application and Research Centre of Selзuk University, Turkey and Macedonian National Collection at the Institute of Biology, 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 <a href="/goto?url=http://www.indexfungorum.org/Names/Names.asp" target="_blank">http://www.indexfungorum.org/Names/Names.asp. </a>BASIDIOMYCOTA AGARICOMYCETES G L O E O P H Y L L A L E S G L O E O P H Y L L A C E A E Veluticeps berkeleyi Cooke, Bull.

Hymenial surface brownish, appearing finely hydnaceous from abundant ste- rile hyphal fascicles (Fig. 3), sometimes deeply cracked, black in KOH. Hyphal pegs present 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 clavate 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 crystals or with brownish yellow mucilaginous or resinous materials (Fig. 4). Context brown, fibrous. Hyphal system monomitic although appearing dimitic, with nodose-septate generative and sclerified hyphae. Sclerified hyphae 2—4 mkm diam. with rare clamp connections, 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 described as dimitic, composed of generative hyphae and thick-walled skeletal hyphae (Welden, Fig. 3. Finely hydnaceous hyphal fascicles of Veluticeps berkeleyi. 383 Fig. 4. Cystidia of Veluticeps berkeleyi. 1967; Hjortstam, Tellerнa, 1990) and monomitic with pseudoskeletal hyphae (Nakasone, 1990).

The forest mainly 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.

The spore dimensions of V. berkeleyi are as approximately (10)12—14.5 Ч 4—5 mkm, but our specimens have spores with the following dimensions: 10.6—11 Ч (2.2) 3.3—4 mkm. The research was financially supported by the Scientific and Technical Research Coun- cil of Turkey (TЬBЭTAK TOGTAG — MKD 2002 / 1 and TOVAG 106O496), the Macedonian Ministry of Science and Education, Scientific Research Projects (BAP 2002/231) Coordinating Office, Selзuk University. We are also indebted to Dr. Nakasone for her generous help, during the identification of the species and for providing helpful comments and corrections. REFERENCES G i l b e r t s o n R. L.

The fungus is associated with brown-rotted wood and causes a brown cubical heartrot on ponderosa pine in America and yellow cypress in Taiwan and Japan. Our specimens were collected from the southern Mediterranean and the west northern parts of Turkey, which is the first finding in the Mediterranean. The fungus was collected on stumps of Juniperus excelsa and J. foetidissima, which are new hosts. Our collections differ from others in having smaller spores. Key words: Veluticeps berkeleyi, wood-decay fungi, Juniperus excelsa, J. foetidissima, Turkey. 386
