Sažetak

The mycoflora of Gorski kotar (a mountainous region in Croatia between Karlovac and Rijeka) was investigated from autumn, 1962, to autumn, 1965. The territory explored includes part of the Risnjak National Park. A total of 282 species of higher fungi was determined, 180 of them not noted previously for this region. The fungi were collected in definite forest associations wherever possible, chiefly Blechno-Abie- tetum and Fagetum abietetosum, but many were found in mixed woods, at the edges of woods and in meadows.
The list of fungi is given in the Croatian text. For the Agaricales the nomenclature is chiefly according to Moser (1955), but follows Pilat (1936—1942) for the Polyporaceae. A few species are taken in a wider sense (Leccinum aurantiacum, Hygrophorus eburneus, Lyophyllum aggregatum, Russula Mariae, R. violacea). The localities are self-evident but, where no locality is given, the fungus was found in the neighbourhood of Crni Lug, a village at the foot of the mountain Risnjak, where most of the investigations were carried out. The forest associations are shown by abbreviations, as indicated in the Croatian text; “miješana šuma7’ means mixed forest (Fagus, Betula, Populus, Abies, Picea), “rub šume” = edge of wood, “livada” = meadow. The genus of the tree is given for the wood-destroying fungi. The months when the fungus was found are indicated by Roman numerals. There finally appears the surname initial of the authors who published records, and, if necessary, the date of publication — see bibliography for further details. The highest altitude is given for those species found towards the top of the Risnjak mountain (1528 m).
Several fungi differ in some details from the published descriptions, or are rarer and less well known. These species are discussed whilst a short description is given for some, of which the following are more noteworthy:
Boletus purpureus Fr. The cap is at first grey brown, similar in colour to B. calopus, but becomes dark red (purple) on scratching. The mature specimens had a dark red cap, the exact colour of B. regius. The stem is yellowish-red above, dark red (purple) below, covered with a fine dark red (sometimes yellow) net. The flesh is yellow, blueing considerably on exposure, as does also the surface of the stem and pores when cut or bruised. This fungus grew chiefly on acid soil in fir forest, although B. purpureus is usually stated to occur on calcareous soil in leafy woods.
Hygrocybe citrinovirens (Lange) J. Schaeff. corresponds closely to the diagnosis of Lange, except for the cap being very acutely conical. The spores, being few and deformed, were consequently not measured.
H. intermedia (Pass.) Fayod had the cap less scaly-fibrous than in the descriptions. The spores were very variable in size and shape, as can be seen from the measurements given in the Croatian text.
Gymnopilus penetrans (Fr.) Murr. The cap is sometimes covered (when young) with fine hairs that closely adhere to the surface, which later become radially ingrown fibers. Some specimens had the remains of a cortina on the stem, and could therefore be considered as the var. hybridus, but did not differ otherwise from the others. The flesh is more yellow than is given in the published descriptions. On the gill margins are many elongated cystidia, which are slightly swollen in the middle and the top. Romagnesi (1962) described the cystidia as “bottle shaped” whilst Moser gave them as “bladder-like”. The spores are very faintly verrucose.
These specimens correspond best with the description of Romagnesi except for the cystidia, the colour of the flesh and the spore ornamention.
Voucher material is deposited in the herbarium of the Institute of botany, Zagreb. Only a few (mostly more common) species were not collected yet, or the material has been destroyed by larvae.
A list of fungi found in these parts by my colleague, Dr. Vrtar, and not previously published, is appended.
