NEW DATA ON MACROMYCETE SPECIES ( BASIDIOMYCOTA ) IN MACEDONIA

A study of mycodiversity in Macedonia is underway. The interest in macrofungi studies in Macedonia has been growing in the past 20 years. According to the research conducted up to now, approximately 2,500 macromycetes species have been recorded in the country. A half of this number is a result of the field and taxonomic work in the Mycological Laboratory in the last decade. This work represents a contribution to the Macedonian mycobiota with some rare fungi species.


EXPERIMENTAL SECTION
The data sources used are as follows: exsiccatae and notes from our own studies, the Macedonian Collection of Fungi (MCF), the database (MAK FUNGI), as well as specimens from other collectors.
The determination of the species was performed during the field research and in the Mycological Laboratory of the Institute of Biology at the Faculty of Natural Science in Skopje, microscopically, by using reagents (Melzers reagent, KOH, Cotton blue, Congo Red, sulphovanillin etc.).Certain species were identified while still in a fresh condition, and the others were to undergo further laboratory analyses.Part of the samples was preserved and deposited in MCF, while all indispensable data about the species were stored in the MACFUNGI database.The identification of the species was carried out using Jülich [15], Allesio [16], Breitenbach & Kranzlin [17,18], Hansen & Knudsen [19], Fernández [20], Krieglsteiner [21,22], Horak [23], Galli [24] and Knudsen & Vesterholt [25].The species names follow Index Fungorum (Kirk, 2016) and MycoBank (Stalpers & Cock, 2016).The species are reported in alphabetical order.All important data pertaining to geographical distribution, altitude, forest association, and data source are provided under each species.The species distribution map was generated in ArcGIS 10.1 based on Digital Elevation Model (ASTERGDEM) (http://asterweb.jpl.nasa.gov/gdem.asp,09.2012).

RESULTS AND DISCUSSION
A list of 15 taxa with important data (localities, associations and/or substrates) and distribution maps is presented.
The following eight species: Amanita verna var.decipiens, Arrhenia griseopallida, Lachnella alboviolascens, Leucocoprinus birnbaumii, Marasmius buxi, Neolentinus schaefferi, Phaeogalera dissimulans and Rubroboletus rubrosanguineus are were found only on single localities, while the other on two or four localities (Figures 1 and 2).Some of the species are more or less specific to the substrate.Marasmius buxi grows on fallen leaves of Buxus sempervirens.This fungus was collected from one locality, although its host is not so rare in the country.According to the host distribution we expected to find M. buxi on more localities.Pholiota populnea occurs on dead or living poplar wood and more rarely also on other hardwoods.It was found on four localities and according to the data available up to now it is a rare species.
Three very rare boletoid species should be pointed out.Xerocomus ichnusanus is a rare thermophilic species distributed in the southern part of Europe, connected mainly to oak forests, but also with other deciduous trees.Our collections originate from oak forest and azonal vegetation with willows and poplars.
Rubroboletus rubrosanguineus is a very rare species, found in the beech forest, on German Mountain.Xerocomus persicolor forms mycorrhiza with oak and beech.It was found only on one locality, in mixed oak and beech forest.
