Morchella (Morchellaceae, Pezizales, Ascomycota) es un género monofilético bien definido. Se caracteriza por poseer una gran plasticidad morfológica entre las especies que lo componen. Algunas están citadas como saprótrofas, mientras que otras como micorrícicas. Su distribución mundial es amplia, con más de 60 especies descriptas. El objetivo del p...

Sugarcane bagasse is a natural source of phenolic compounds. However, these compounds are bound to lignocellulose components, reducing their ability to function as good antioxidants. These linkages are hydrolyzed by enzymes like β-glucosidases, increasing free phenolics. Auricularia is a food-grade genus capable of producing β-glucosidases. The aim...

Five new lanostanoid triterpenes were isolated from the extract of R. microporus. Three of the metabolites (1–3) present a Δ8,9 skeleton with an uncommon keto functionality at C–1. Another compound (4) has an unprecedented rearranged skeleton in which methyl-19 was transposed to C–1, with conjugated double bonds at Δ1–10 and Δ8–9. All of the compou...

Six strains belonging to five species of Polyporus (P. arcularius, P. arcularioides, P. tricholoma, P. cfr. tricholoma, and P. varius), collected from an Atlantic Forest area in Misiones (Argentina), where species usually grow exposed to high temperatures and humidity, were identified by morphological and molecular analyses. P. tricholoma (BAFC 453...
Article
Full-text available
In the last decades, several phylogenetic studies have shown that Polyporus is polyphyletic; accordingly, several genera have been newly described or reinstated. Nevertheless, the phylogenetic position of many species in the genus remains highly contentious, particularly those traditionally included in the Polyporus infrageneric group Polyporus s.s...

Polyporus dictyopus, with a large number of heterotypic synonyms, has been traditionally considered a species complex, characterized by wide morphological variation and geographic distribution. Thus, neotropical specimens previously identified as P. dictyopus from Amazonia, Cerrado and Atlantic Forest biomes were studied based on detailed macro- an...

Macrofungi present in a recovered zone of Atlantic Forest (Misiones, Argentina). Atlantic Forest is an ecosystem historically managed without restrictions. Over the years, this situation led to a fragmentation of the forest environment with the consequent loss of habitats for all kinds of organisms in the region. The present work is a checklist of...

The extracellular production of ligninolytic enzymes by xylariaceous and diatrypaceous species from Argentina was investigated. Among them, a new species, Eutypa microasca, was evaluated. Its morphological characteristics (e.g.: very small asci) along with the molecular analyses, support the hypothesis of the new taxon. Ligninolytic enzyme producti...

En Argentina existen actualmente bases de datos de aves, mamíferos y plantas entre otros, pero existe un vacío en lo que respecta a la diversidad fúngica. Esto puede deberse a la limitada cultura micofaga en el país. En otros países como España, Finlandia, Noruega y Suecia, existen sitios online que albergan descripciones, imágenes, mapas de distri...

Culture filtrates from the white rot fungus Trametes trogii were used for the degradation of two azo dyes: Xylidine and Methyl Orange. These culture filtrates showed a great potential for decolorizing even high concentrations of both azo dyes, without the addition of redox mediators, possibly due to the synergistic action of their high contents of...

MIND.Funga comprises scientific concerns that lead us to develop research of short- and long- term, mainly from unexplored and threatened areas. For that, we use an integrative approach (systematics, phylogeny, taxonomy, ecology, metagenomics, etc.) in our studies with macro- and microfungi. In general, our research objects are wood associated fungi, as polypores (Hymenochaetales and Polyporales), which play an important role in the maintenance of natural ecosystems. We also have interest in the Cordyceps s.l. (Hypocreales), a fantastic group of entomopathogenic organisms, which mainly use insects to develop part of their life cycle. More recently, we are devoting ourselves to the recognition of fungal communities associated with plants (endophytes) and soil, in order to understand the ecology and real magnitude of fungal diversity in the ecosystems. Much of our studies are focused on systematics, based on molecular, morphological and ecological characters. Therefore, we use phylogenetic analysis to understand the evolutionary history of different lineages and for taxonomical species delimitation. On the other hand, we are interested in the fungi importance in ecological process, how fungi respond to climate changes and its conservation purposes. Our activities: 1) Research exploration of unique and endangered ecosystems (cloud forests, for example) in order to document also particular funga; 2) Fungi and plants inventories, recording the species distribution and its conservation status; 3) Resolution of taxonomical complexes and description of new taxa; 4) Recognition of fungal communities across vegetation types (plants and soil), monitoring over time those funga; 5) Publication and scientific diffusion of fungi novelties and curiosities.
