TL;DR: Lycogala exiguum is noted for the first time in the state of Santa Catarina, Cribraria languescem in the South and CribRaria vulgaris in Brazil.
Abstract: A survey on Myxomycetes was made in the woods of Lagoa do Peri and Lagoa da Conceicao in 1990, considering the absence of reports of this kind for the city of Florianopolis, when the following species were registered: Lycogala exiguum Morg. (Enteridiaceae); Cribraria languescem Rex, C. vulgaris Schr. (Cribrariaceae); Arcyria cinerea (Bull.) Pers. Hemitrichia serpula (Scop.) Rost., H. calyculata (Speg.) Fair and Hemitrichia sp (Trichiaceae); Stemonitis fusca Roth, and S. smithii Macbr. (Stemonitaceae). Exicates are deposited at the herbarium UFP. Lycogala exiguum is noted for the first time in the state of Santa Catarina, Cribraria languescem in the South and Cribraria vulgaris in Brazil. The survey raises up the number of registers refered to the state of Santa Catarina to 47 species. A review of the studies on this group of organisms in Santa Catarina is given as well as the area where each species occur in this state and in different regions of Brazil.

TL;DR: In this paper, the behavior of a spinor charged particle in background conical spacetimes was studied and the self-potentials that arise from the non-trivial topology of the spacelike sections of these spacetomes were considered as external electrostatic potentials.
