The higher fungi in the neighbourhood of Zagreb, II

Sažetak
This list is a continuation of the one published in 1964 by the same author. The fungi were collected mainly from 1963 to the spring of 1966; several species found earlier, but identified later, are also included. During 1963, owing to the favourable weather conditions, the fungi were growing in exceptionally large quantities, so that rich collections could be made. The following two years were poor in this respect, but nevertheless many species were collected.
As the species previously found in the region being investigated are indicated by the initials of the authors and the date of publication, it is easily seen that 164 species were not previously recorded, although some of them were noted in other regions of Croatia. Also, the present author either did not find some of species mentioned by other workers, or has found them elsewhere.
The nomenclature follows Domahskiet al. (1967) for the Polypo- raceae and similar families, and Moser for Ascomycetes (1963) and Agaricales (1955). For the later the names that could be found in Dennis et al. (1960) are added in brackets. Voucher specimens have been deposited in the herbarium ZA.
Some of the fungi found are, according to the literature, rather rare, i. e. Neohulgaria foliacea, Polyporus forquignonii, Piptoporus quercinus, Hygrocybe calyptraeformis and Cortinarius ionochlorus. As the description of the last seems to have been rarely published, it is added here.
The cap is olive-green, with ingrown striae, becoming almost scaly in the middle. The stipe is sulphur yellow, fibrillose, with a marginate bulb; mycelium at the base is concolorous; lamellae are violet when young, later becoming almost cinnamon brown. The flesh of the cap is greenish, but yellow in the stipe, with a peippery smell. Reactions with KOH and JJK are negative. Spores are verrucose, 9.5 — 12.5 X 5.5 —7 p. Found only twice, in the course of several years, as either one or two specimens, in the wood of Quercus pubescens and Ostrya carpinifolia.
Several fungi differ in one or more details from the descriptions.
Mycena tintinnabulum had all the characteristics of the species, but the cystidia (Fig. 4a) are different from those of the typical form (Fig. 4c). Somewhat similar cystidia has an American form (Fig. 4b) mentioned by Kühner (1938).
The species identified as Hebeloma edurum was found in same wood as mentioned above, but it grew also in cultivated pine wood. The stipe is whitish with fine brown squamulae in zones, broadening at the base into brownish, round or somewhat fusiform bulb, but is also often without bulb. Taste bitter, smell pleasant. Spore finely verrucose, 9.5 — 12.5 X X 5.5 — 7.5 p.
Cortinarius violaceus was found in frondose wood, and is according to Moser (letter) a separate variety.
Phlegmacium rufoolivaceus has violet lamellae when young, and perhaps represents the form with similar lamellae, mentioned by Kühner and Romagnesi (1955). This is also the opinion of Moser (letter).
A curious Clitocybe, found as only a single specimen in Maksimir Park (mostly Quercus, Carpinus, Fagus) is described (Fig. 3). The cap is brownish like leather, with thin edges, lamellae are very dense, decurrent, of a creamy colour with brownish edges, and can be quite easily separated from the cap. The stipe is somewhat excentric, striate, with what appears to be like a net of brown fibrillae. The flesh is thin, white, with a strong but not unpleasant smell. Spores are hyaline, (5.5) 6.5 —7.5 (8) X X 3.5 — 4 (4.5) p. They do not turn blue with JJK. It shows some similarities with C.cacabus sensu Ricken (1915), but this species has bigger spores and the cap is funnel-shaped. The spores are also somewhat similar in shape to those of C. inornata, but shorter, and, moreover, the lamellae in this species are not decurrent.
