The samples of 4 mushroom species from the genus Leccinum ((Leccinum pseudoscabrum (Kallenb.) Šutara, scabrum (Bull.) Gray, duriusculum (Schulzer ex Kalchbr.) Singer, and albostipitatum den Bakker & Noordel) were picked 6 forested areas Slovakia in 2020 (Čačín – Jelšovec, Hliník Hronom, Kurima Taraš, Mníšek nad Popradom, Snina Štefekovo, Žákylské pleso).

We have recorded from single neurons in the retinorecipient layers of the superior colliculus of the cat. We distinguished several functionally distinct groups of collicular neurons on the basis of their velocity response profiles to photic stimuli. The first group was constituted by cells responding only to photic stimuli moving at slow-to-moderate velocities across their receptive fields (pre...

The genus Pseudovirgaria, based on P. hyperparasitica, was recently introduced for a mycoparasite of rust sori of various species of Frommeëlla, Pucciniastrum and Phragmidium in Korea. In the present study, an older name introduced by Saccardo based on European material, Rhinotrichum griseum, is shown to resemble P. hyperparasitica. Morphological study and ITS barcodes from fresh collections of...

The U.S. public's current knowledge about politics is compared with levels of knowledge in the 1940s and 1950s. Fourteen questions asked by Gallup on various surveys from 1945 to 1957 were included on a larger survey of political knowledge conducted by telephone in 1989 with a randomly selected sample of 610 adult U.S. residents. On 8 of the 14 items, the percentage answering correctly in 1989 ...

The distribution of terminal fields of retinocollicular fibers was studied in squirrel monkeys with the autoradiographic technique. The terminals were aggregated into patches which were separated by intervening gaps. The ipsilateral patches were particularly distinct. The patches as well as th gaps ranged in size from 50 to 200 microns. In the most posterior aspect of the contralateral superior...

In the present study, the composition of bio-elements (K, Na, Mg, Ca, Fe, Cu, Zn) and toxic elements (Ag, Cd) in seven edible mushrooms from the rural and woodland region of Morąg (north-eastern Poland) and the rural and industrial region of the Tarnobrzeska Upland (south-eastern Poland) were investigated using a validated method. The species examined were Boletus edulis, Cantharellus cibarius,...

Mercury content has been determined separately in the caps, stalks and whole fruiting bodies of thirteen species of popular wild edible mushrooms of the genus Boletus, Xerocomus, Leccinum, Suillus, Tricholoma, Rozites, Sarcodon and Cantharellus collected from Augustowska Forest, which is located in an unpolluted region in the northeastern part of Poland. The mushroom samples were collected in t...
