Abstract

As a result of the systematic research into the mycobiota of Macedonia, data on 30 species of the genus Boletus L. have been provided. Eight species (B. dupainii, B. ferrugineus, B. fragrans, B. impolitus, B. pulchrotinctus, B. rhodopurpureus, B. rubellus and B. torosus) are new for Macedonia. This paper presents the first complete survey of Boletus species with a discussion on their ecology and distribution in the country. Key words: mycobiota, genus Boletus, ecology, distribution, Macedonia

INTRODUCTION

To date, 30 species from the genus Boletus L. have been recorded in the Republic of Macedonia. Thus far some of these species have been individually published in several scientific papers as follows: Boletus aereus (KARADELEV et al., 2002b), B. appendiculatus (SYLEJMANI, 1980; TORTIĆ, 1988; KARADELEV et al., 2003b; KARADELEV & RUSEVSKA, 2004), B. armeniacus (KARADELEV et al., 2003a), B. badius (KARADELEV, 2000b; KARADELEV & RUSEVSKA, 2004; KARADELEV et al., 2004), B. calopus (SYLEJMANI, 1980; TORTIĆ, 1988; KARADELEV & RUSEVSKA, 2002; KARADELEV et al., 2003b; KARADELEV et al., 2003a; KARADELEV et al., 2004; KARADELEV & RUSEVSKA, 2004), B. chrysenteron (TORTIĆ, 1968, 1988; SYLEJMANI, 1980; KARADELEV, 2000b; KARADELEV & RUSEVSKA, 2000; KARADELEV et al., 2002 a, b; KARADELEV & RUSEVSKA, 2002; KARADELEV et al., 2003a; KARADELEV & RUSEVSKA, 2004; RUSEVSKA & KARADELEV, 2004), B. edulis (TORTIĆ, 1968, 1988; SYLEJMANI, 1980; KARADELEV & POPOVSKI, 1995; KARADELEV & RUSEVSKA, 2000; KARADELEV, 2000b; KARADELEV et al., 2002 a, b; KARADELEV et al., 2003a; KARADELEV et al., 2003b; KARADELEV & RUSEVSKA, 2004), B. erythropus (TORTIĆ, 1968, 1988; KARADELEV & POPOVSKI, 1995; KARADELEV et al., 2002 a, b; KARADELEV & RUSEVSKA, 2002; KARADELEV et al., 2003a; KARADELEV & RUSEVSKA, 2004), B. fechtneri (TORTIĆ, 1968, 1988; KARADELEV et al., 2002b; KARADELEV et al., 2003a; KARADELEV & RUSEVSKA, 2004), B. luridus (PILÁT & LINDTNER, 1939; TORTIĆ, 1988; KARADELEV, 2000b; KARADELEV et al., 2002 a, b; KARADELEV et al., 2003a; KARADELEV et al., 2003b; KARADELEV et al., 2004), B. pinophilus (KARADELEV & RUSEVSKA, 2002; KARADELEV et al., 2003a), B. porosporus (TORTIĆ, 1988) B. pseudoregius (KARADELEV et al.,

MATERIALS AND METHODS This survey includes citation of the published data as well as all the unpublished records on species of the genus Boletus collected in Macedonia up till now. The sources of this list include all the previously published papers, exsiccates deposited in different collections, research notes of the present authors, other individual collectors, and data from field research trips organised by Macedonian Mycological Society (MMS), Biology Students’ Research Society (BSRS), students’ field research trips, etc. Part of the specimens collected in Macedonia has been deposited in the following collections: Botanical Department, Faculty of Science in Zagreb (ZA), National History Museum in Belgrade (BEO), and National Museum Prague (PRM). The data from the collection SKO and from the personal fungarium of M. Karadelev have been included in the National Collection of Fungi - FUNGI MACEDONICI (MAK), housed at the Institute of Biology, Faculty of Natural Science, Ss Cyril and Methodius University in Skopje. For identification of the species the following keys and identification guides have been consulted: KÜHNER & ROMAGNESI (1953), PILÁT (1959, 1969), SINGER (1962), MOSER (1983), ALLESIO (1985), KREISEL (1987), BREITENBACH & KRÄNZLIN (1991), HANSEN & KNUDSEN (1992), FERNÁNDEZ (1997), KRIEGLSTEINER (2000), HORAK (2005). The nomenclature has been made according to Index Fungorum 2005. The synonyms are also specified. The species are reported alphabetically, with citation of previous publications and collections in which the collected material has been deposited. The species distribution data are presented as follows: geographical distribution, altitude, forest association, date and source. The survey incorporates data published or collected by 31 October, 2006.

DISCUSSION AND CONCLUSIONS

A total of 30 species of the genus Boletus have been registered. Among them, eight species are new for the mycobiota of the Republic of Macedonia. Boletus aereus is found in oak forests as well as in Pinus plantings. According to HORAK (2005), Boletus aereus forms mycorrhiza with broadleaved trees, particularly Quercus and Castanea, and grows mainly in deciduous forests. To date, one finding only has been published in KARADELEV et al., 2002b, while the data from five localities have been published in the present paper for the first time. This species has been included in the Preliminary Red List of Macromycetes of Macedonia (KARADELEV, 2000a). Boletus appendiculatus grows in deciduous and mixed forests. In Macedonia it is found in deciduous forests (oak and beech) and Abieti-Fagetum. According to HORAK (2005), this species forms mycorrhiza with deciduous trees, especially Fagus and Quercus, and KRIEGELSTEINER (2000) also cited coniferous trees (Picea abies, Pinus sylvestris) as mycorrhizal partners. Two localities are known (SYLEJMANI, 1980; TORTIĆ, 1988; KARADELEV et al., 2003; KARADELEV & RUSEVSKA, 2004) and three localities are new for Macedonia. As maintained by KARADELEV et al. (2003a), Boletus armeniacus has been registered at one locality (Pelister Mt.), in Digitali viridiflorae-Pinetum peuces. HORAK (2005) cited broadleaved trees (Quercus, Fagus, Castanea, Corylus, Tilia) and Pinus and Abies from conifers, as mycorrhizal partners. The distribution of this species in the Republic of Macedonia has not been sufficiently investigated, but most likely it forms mycorrhyza with Pinus peuce.

Boletus badius is a common species; it grows in coniferous forests, rarely in hardwood. Few localities are known for the Republic of Macedonia (KARADELEV 2000b, KARADELEV & RUSEVSKA, 2004; KARADELEV et al., 2004), two are new (the surroundings of Bogdanci and Jablanica Mt.), in oak, beech and pine forests, between 150 and 1700 m altitude. Boletus calopus grows in deciduous and conifer forests. It forms mycorrhiza with Fagus and Picea in particular (HORAK, 2005). In Macedonia it has been found growing in beech, oak forest, and molika pine associations. This widespread species is known from several localities, mostly from the western and southern parts of the country. Boletus chrysenteron is a common species, grows in hardwood and coniferous forests. In the Republic of Macedonia it is a widespread species, known from many localities, thirteen are new, between 150 and 1900 m altitude. It has been noted in different associations: beech, oak, molika pine forests, in pine plantings, etc. Boletus dupainii is a rare species, and, as indicated by HORAK (2005), it forms mycorrhiza with deciduous trees (Quercus, Fagus), sometimes with conifers. In Macedonia it has been noted at one locality (Jablanica Mt.), in oak forest; therefore, a conclusion of its distribution cannot be drawn. This is a new species for the mycobiota of Macedonia. Boletus edulis in Macedonia is found in hardwood and coniferous forests, between 150 and 1700 m altitude. Several localities are known (TORTIĆ, 1968; SYLEJMANI, 1980; TORTIĆ, 1988; KARADELEV & POPOVSKI, 1995; KARADELEV & RUSEVSKA, 2000; KARADELEV, 2000b; KARADELEV et al., 2002 a, b; KARADELEV et al., 2003a; KARADELEV et al., 2003b; KARADELEV & RUSEVSKA, 2004). According to the current data, it is a widespread and the most common species from the genus. Boletus erythropus is observed in various associations (deciduous, conifer, molika pine, fir and spruce forests). This species is common in our country, found in more than ten localities, where six are new. As per HORAK (2005), Boletus fechtneri is mycorrhizal with broadleaved trees, especially Fagus, but in Macedonia TORTIĆ (1988) cited it for Gentiano luteae-Pinetum peuces abietetosum. In Macedonia it is registered at five localities and according to data available so far, it is a rare species and has been included in the Preliminary Red List of Macromycetes of Macedonia (KARADELEV, 2000a). Boletus ferrugineus is associated with coniferous trees (HORAK, 2005). In the Republic of Macedonia it has been observed at two localities, (Kitka and Kožuf Mt.), in hornbeam-oak and beech forests and is a new species for the country. According to ALESSIO (1985), Boletus fragrans is a rare species and grows in deciduous forests. This is a new species for Macedonia, recorded at two localities in beech and oak forest, ca. 700 and 1600 m altitude. Boletus impolitus forms mycorrhiza with broadleaved trees, especially Quercus. It has been observed at two localities (Katlanovo, Skopska Crna Gora) in oak forests, published in this paper for the first time. Boletus luridus in Macedonia is found in many localities throughout the country, mostly in oak and beech forests, but also in Digitali viridiflorae-Pinetum peuces

(KARADELEV et al., 2003a) and Fraxinetum angustifoliae-pelise (KARADELEV et al., 2004) between 100 and 1700 m altitude. Boletus pinophilus grows in coniferous forests. KRIEGELSTEINER (2000) cited Pinus sylvestris and Picea abies as mycorrhizal partners. In Macedonia it is noted in the following associations: Abieti-Piceetum scardicum, and molika pine associations (Digitali viridiflorae-Pinetum peuces, Gentiano luteae-Pinetum peuces abietetosum) with a possibility of mycorrhiza with Pinus peuce. In Macedonia it is noted in five localities; the data concerning Kozjak, Skopska Crna Gora and Šar Planina Mt. are new. According to HANSEN & KNUDSEN (1992), Boletus porosporus grows in hardwood forests. In the Republic of Macedonia this species is known from Šar Planina Mt. (TORTIĆ, 1988, published as Xerocomus truncatus, after the revision by Pouzar). Two localities (Pelister Mt. and the vicinity of Skopje), are new. It has been registered at 800 and 1300 m altitude, in beech forest and meadow. Boletus pseudoregius forms mycorrhiza with broadleaved trees, especially Fagus, Quercus. In Macedonia it is found on two localities, in beech and oak forest, at ca. 800 and 1200 m altitude. According to KRIEGELSTEINER (2000), this species is predilected to warm habitats. According to ALLESIO (1985), Boletus pulchrotinctus grows in deciduous forests, and is rare. In Macedonia it is found on one locality (Vodno Mt.) in oak forest at ca. 800 m altitude. This is a new species for the mycobiota of Macedonia. Boletus pulverulentus is found in beech and oak forest. It is not common but widespread from lowlands to mountain regions, and according to KARADELEV (2000a) it is included in the Preliminary Red List of Macromycetes of Macedonia. Our data are from 1000 to 1500 m altitude. According to KARADELEV et al. (2004), in Macedonia Boletus purpureus has been found only at one locality (Jakupica Mt.) in oak forest; therefore, a conclusion of its distribution cannot be drawn. Boletus queletii according to current data is not rare in Macedonia. It is found in oak and beech forests but also in parks. One locality is known from KARADELEV, 2000b, KARADELEV et al., 2003b and KARADELEV & RUSEVSKA, 2004, while eleven localities are new. Boletus radicans grows in deciduous forests. Our data are from beech forest. One locality (Pelister Mt.) is new. In Macedonia, Boletus regius is found in oak and beech forests and according to Horak (2005), it forms mycorrhiza mainly with Quercus and Fagus. One locality (Jakupica Mt.) has been published by SYLEJMANI (1980) and TORTIĆ (1988), whereas seven localities are new. This species is incorporated in the Preliminary Red List of Macromycetes of Macedonia (KARADELEV, 2000a). Boletus reticulatus is a widespread species and grows in hardwood forests, especially Fagus and Quercus. In Macedonia it has been recorded in deciduous forests (oak and beech). Up to date, only one datum related to Šar Planina Mt. has been published in KARADELEV et al., 2002a. Therefore, ten localities are new for this species.

Boletus rhodopurpureus is found in oak forests, at four localities, from 850 to 1500 m altitude. HORAK (2005) cited Fagus and Quercus as its mycorrhizal partners. Boletus rhodoxanthus is registered in oak and beech forests, one locality (Šar Planina Mt.) has been published by PILÁT & LINDTNER (1939) and TORTIĆ (1988), five localities (mountains of Bigla, Kožuf, Pelister, Skopska Crna Gora and Galičica, between 800 and 1500 m altitude) are new. HORAK (2005) cites Fagus, Quercus and Castanea as mycorrhizal partners. This species is put in the Preliminary Red List of Macromycetes of Macedonia (KARADELEV, 2000a). Boletus rubellus grows in mixed hardwood forests, parks, gardens. It is a new species for the Republic of Macedonia, recorded at five localities (mountains of Kožuf, Pelister, Šar Planina and the surrounding area of Kavadarci and Prespa), between 1000 and 1700 m altitude, in pine-oak, beech forests, Digitali viridiflorae-Pinetum peuces with Fagus and in parks. Boletus satanas forms mycorrhiza with broadleaved trees. In Macedonia it is found in deciduous forests, but according to KARADELEV et al. (2004), it has also been noted in molika pine forest (Pelister Mt.). Five localities are new and this species is one of the six Boletus species in the Preliminary Red List of Macromycetes of Macedonia (KARADELEV, 2000a). Boletus subtomentosus is a widespread species; it grows in hardwood and coniferous forests. In the Republic of Macedonia it has been noted in five localities (TORTIĆ, 1988; KARADELEV & RUSEVSKA, 2002; KARADELEV et al., 2003a), and seven are new. It has been registered between 250 and 1500 m altitude, in hornbeam-oak and molika pine associations. HORAK (2005) cites Boletus torosus as mycorrhizal with broadleaved trees, sometimes with conifers, but according to BREITENBACH & KRÄNZLIN (1991), it primarily grows near Fagus. In Macedonia it has been found in oak and beech forests, at two localities (mountains Pelister and Kožuf) at ca. 800 and 1300 m altitude. It is a new species for the mycobiota of the country.

SUMMARY A total of 30 species of the genus Boletus L. have been recoreded. Eight species (B. dupainii, B. ferrugineus, B. fragrans, B. impolitus, B. pulchrotinctus, B. rhodopurpureus, B. rubellus and B. torosus) are new for the mycobiota of Macedonia. According to KARADELEV (2000a), six species are contained in the Preliminary Red List of Macromycetes of Macedonia as rare species (B. pulverulentus, B. rhodoxanthus) or species threatened due to excessive exploitation (B. aereus, B. fechtneri, B. regius and B. satanas).

ACKNOWLEDGEMENTS We are indebted to Prof. Gerhard Kost from Phillips University, Marburg, Germany for his assistance in determination of certain Boletus species, and to Matthias Theiss from Biedenkopf, Germany, for the photographic material provided. We also express gratitude to all the collectors of the mycological material.
