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...

Lichens were investigated in Brazil a small area along the Roosevelt River Amazonas; 25 species are first reports for Brazil, and 190 additional records Amazonas state. As many as 24 described that new to science: Allographa lineatipruinosa, variopruinata, Arthonia xanthopycnidiata, Astrothelium aurantioseptemseptatum, bulbosum, coloratum, inspersonovemseptatum, insulare, laureroides, marjolein...

suns. The extension of the Andromeda nebula beyond the photographic limits is presumably typical of what may be found for other such objects. Comparisons with the surface brightness of the galaxy are still hampered by uncertainties in the data for our own system. There may be no part of the galaxy which, seen from outside, would be as bright as the central portion of M 31. In the latter system ...

This study examines the richness of phytoplanktonic species found in one aquifers Lagunas de Zempoala National Park. The samples were carried out monthly from September 2018 to February 2019. During this period, 26 integrated seven divisions, 20 families and classes recognized, among which Bacillariophyceae class stands with greatest diversity (eight species). Staurastrum bulbosum was most freq...

Intergenomic translocations between wheat, Hordeum chilense and Hordeum vulgare have been obtained in tritordeum background. Advanced lines from the crosses between three disomic chromosome addition lines for chromosome 2Hv, 3Hv, and 4Hv of barley (Hordeum vulgare) in Triticum aestivum cv. Chinese Spring (CS) and hexaploid tritordeum (2n = 6x = 42, AABBHchHch) were analyzed. Multicolor FISH usi...
