The Yungas of northwestern Argentina are located at the southern limit of a system of tropical and subtropical cloud montane forests extending on the oriental slope along the Andes in South America. Although they cover only less than 2% of the whole Argentinian surface, these mountain forests harbor over 50% of its biodiversity (flora and fauna) (B...

... Our findings increase the number of Capronia species known in Argentina to eight. Unlike the species recorded here from the southernmost forest of Argentina, the species previously mentioned for the country were collected at lower latitudes, in places with tropical to subtropical climate: C. coronata, C. nigerrima and C. pulcherrima in the Yungas (northwestern region of Argentina), the former also recorded from Misiones Province, and C. pilosella from Buenos Aires (Carmarán et al. 2002;Catania & Romero 2008;Gallo et al. 2014). All eight species in Argentina were found growing on wood or bark of standing trees or fallen branches, and no asexual morph was found associated with any of them. ...
Three new species belonging to Capronia are described from plants native to the Andean Patagonian forests, Argentina. The first record of C. chlorospora in South America is also reported. The identity of the three new species is based on detailed morpho-anatomical observations as well as analyses of ITS and LSU nuclear rDNA. A key to the Capronia species present in Argentina is provided.
The cellulolytic activity of fungi growing in the subtropical rainforest of Misiones (Argentina) represents a challenge in the technological development of the production of cellulosic bioethanol in the region using native sources. These fungi are promising to obtain sustainable enzyme cocktails using their enzymes. Cellulolytic ability of 22 white-rot fungi isolated from the subtropical rainforest of Misiones-Argentina in agar medium with two types of cellulosic substrates, carboxy-methylcellulose or crystalline cellulose, were comparatively analyzed, and the activity of two cellulolytic enzymes was evaluated in liquid medium. Although all isolates were able to grow and degrade both substrates in agar medium, and to produce total cellulase Filter paper (FPase) and endo-β-1,4-glucanase (EG) activities in broth, the isolate Irpex sp. LBM 034 showed the greatest enzymatic levels (FPase, 65.45 U L⁻¹; EG, 221.21 U L⁻¹). Therefore, the ITS sequence of this fungus was sequenced and analyzed through a phylogenetic analysis. These results indicate that the isolate LBM 034, corresponding to Irpex lacteus, has a promising cellulolytic ability and enzymes such as EG useful in sustainable saccharification of cellulosic materials in the region.
Twenty nine species of Ascomycetes collected in the guadual from Natural Reserve of “Montaña del Ocaso” at the municipality of Quimbaya in the Quindío Department from Colombia are studied. Of these, 15 species only grow on decayed debris of Guadua angustifolia, 10 were found on decay wood of trees and four are parasites of others ascomycetes fungi. Of the collected species, only Cookeina sulcipes has been mentioned for Quindío Department, the remaining species are cited for the first time to this Department, and of these, 19 are new records from Colombia.
