Predmetnim istraživanjem utvrđivana je koncentracija Fe, Zn i Cu u deset samoniklih jestivih vrsta gljiva Parka prirode Medvednica. Sličnost između ispitivnih vrsta gljiva ustanovljena je klaster analizom na temelju koncentracije navedenih metala u plodnom tijelu gljiva. Analiza teških metala provedena je metodom XRF – rentgenske fluoroscentne spektrometrije. Najveća koncentracija Fe od 153.96 mg kg<sup>–1</sup> utvrđena je u Tricholoma portentosum, dok je najveća koncentracija Zn od 90.60 mg kg<sup>–1</sup> ustanovljena u vrsti Tricholoma terreum. Najveća koncentracija Cu utvrđena je u vrsti Macrolepiota procera (78.8 mg kg<sup>–1</sup>). Analizom teških metala u gljivama ustanovljene su značajne razlike (p<0.05; p<0.001) u koncentraciji Zn i Cu između saprofitskih i ektomikoriznih vrsta gljiva. Utvrđena je znatno veća koncentracija ispitivanih metala u klobuku u odnosu na stručak. Sve istraživane vrste gljiva isključene su kao mogući bioindikatori onečišćenja okoliša željezom. Klaster analiza provedena na temlju koncentracije teških metala u gljivama otkrila je veliku sličnost vrsta gljiva koje pripadaju istom rodu i djelomične sličnosti vrsta iste ekološke pripadnosti.

Handsome fungus beetle Lycoperdina succincta (Linnaeus, 1767) from the family Endomychidae is the first recorded from Kazakhstan (North Kazakhstan, Akmola, and North Kazakhstan regions and South-East Kazakhstan, Almaty region). The finds of L. succincta from the Almaty region of Kazakhstan are currently the southernmost localities for this species and a new record for Central Asia. Coprinus comatus (O.F. M&uuml;ller) Persoon, 1797, Tulostoma volvulatum I.G. Borshchov, 1865, Bovistella utriformis (Bulliard) Demoulin &amp; Rebriev, 2017 and Tricholoma terreum (Schaeffer) P. Kummer, 1871 for L. succincta were recorded from Lazakhstan also. A key to &nbsp;determining the &nbsp;known genera and species of Endomychidae from Kazakhstan is given.

Macrolepiota procera, commonly called the Parasol Mushroom, is a delicious mushroom collected from the nature and commonly consumed by the public in many regions of Turkey. This study was conducted to determine the optimum culture conditions (pH, temperature, carbon and nitrogen sources) for mycelial growth of M. procera. Three pH values (pH 5.0, 5.5 and 6.0), four incubation temperatures (15, 20, 25 and 30°C), seven carbon (C) sources (dextrose, glucose, lactose, maltose, mannitol, sucrose and xylose) and six nitrogen (N) sources ((NH4)2HPO4, NH4NO3 and Ca(NO3)2, malt extract, peptone and yeast extract) were investigated. In the second step of the study, the effect of seven pH values (4.0, 4.5, 5.0, 5.5, 6.0, 6.5 and 7.0) on the mycelial colony diameter was examined at 20 and 25°C since these temperatures gave the best mycelial growth in the previously conducted temperature experiment. The best mycelial growth was determined at pH 6.0. The optimum temperature for mycelial growth of M. procera was found as 25°C. The use of glucose as carbon source and yeast extract and peptone as nitrogen source in the culture medium gave the best results for mycelial growth. Determining of optimum culture conditions for mycelial growth of M. procera will provide important contributions to the fortcoming studies on it’s commercially cultivation in Turkey.

AbstractIt has been known since the 1970s that differences exist in the profile of element content in wild-growing mushroom species, although knowledge of the role of mushroom species/families as determinants in the accumulation of diverse element remains limited. The aim of this study was to determine the content of 63 mineral elements, divided into six separate groups in the fruit bodies of 17 wild-growing mushroom species. The mushrooms, growing in widely ranging types of soil composition, were collected in Poland in 2018. Lepista nuda and Paralepista gilva contained not only the highest content of essential major (531 and 14,800 mg kg−1, respectively of Ca and P) and trace elements (425 and 66.3 mg kg−1, respectively of Fe and B) but also a high content of trace elements with a detrimental health effect (1.39 and 7.29 mg kg−1, respectively of Tl and Ba). A high content of several elements (Al, B, Ba, Bi, Ca, Er, Fe, Mg, Mo, P, Sc, Ti or V) in L. nuda, Lepista personata, P. gilva and/or Tricholoma equestre fruit bodies belonging to the Tricholomataceae family suggests that such species may be characterised by the most effective accumulation of selected major or trace elements. On the other hand, mushrooms belonging to the Agaricaceae family (Agaricus arvensis, Coprinus comatus and Macrolepiota procera) were characterised by significant differences in the content of all determined elements jointly, which suggests that a higher content of one or several elements is mushroom species-dependent.

ABSTRACT The symbiosis between ectomycorrhizal fungi and trees is an essential part of forest ecology and depends entirely on the communication between the two partners for establishing and maintaining the relationship. The identification and characterization of differentially expressed genes is a step to identifying such signals and to understanding the regulation of this process. We determined the role of hydrophobins produced by Tricholoma terreum in mycorrhiza formation and hyphal development. A hydrophobin was purified from culture supernatant, and the corresponding gene was identified. The gene is expressed in aerial mycelium and in mycorrhiza. By using a heterologous antiserum directed against a hydrophobin found in the aerial mycelium of Schizophyllum commune, we detected a hydrophobin in the symbiosis between T. terreum and its native pine host Pinus sylvestris. The hydrophobin was found in aerial mycelium of the hyphal mantle and also in the Hartig net hyphae, which form the interface between both partners. Interestingly, this was not the case in the interaction of T. terreum with a host of low compatibility, the spruce Picea abies. The differential expression with respect to host was verified at the transcriptional level by competitive PCR. The differential protein accumulation pattern with respect to host compatibility seen by immunofluorescence staining can thus be attributed at least in part to transcriptional control of the hyd1 gene.
