“…Dentro de las especies fúngicas comestibles presentes en Chile, se encuentra la especie Grifola gargal (Figura 1), descrita por Singer (1969). La especie corresponde a un hongo nativo y endémico del cono sur de Sudamérica, presentes en los bosques andino patagónicos de Chile y Argentina, que crece sobre ramas y fustes caídos o en madera muerta en pie, preferentemente en especies del género Nothofagus, como roble (Nothofagus obliqua), coigüe de Chiloé (Nothofagus nitida), coigüe de Magallanes (Nothofagus betuloides) (MMA, 2021) o en especies como la tepa (Laurelia philipiana) (De Bruijn et al, 2008) o en tineo (Weinmania trichosperma) (Palma et al, 2021), reportándose además, fructificaciones en Populus nigra en Argentina (Pozzi et al, 2009). En Chile se distribuiría entre las regiones de Ñuble y Aysén (Sánchez Jardón et al, 2017).…”

Se estudió el comportamiento de dos cepas del hongo saprófito comestible Grifola gargal bajo condiciones de cultivo in vitro. Se analiza el crecimiento en diámetro (CD), velocidad media de crecimiento (VMC) y biomasa (B) de cultivos creciendo en los medios PDA (Papa Dextrosa Agar), BAF (Biotina Aneurina ácido Fólico), MYPA (Extracto de malta levadura agar peptona y PGYA (peptona-extracto de levadura-glucosa) y bajo 5 niveles de pH (4,0, 4,5, 5,0, 5,5 y 6,0). Los resultados indican interacciones estadísticamente significativas entre los factores medio de cultivo y pH para las tres variables medidas. Se observa que, tanto a nivel de cepas como de especie, el medio MYPA con pH 4,5 presenta los valores más altos para CD, VMC y B. Comparaciones entre valores promedios del CD, VCM y B, muestran alta correlación entre estos parámetros para las cepas estudiadas.

“…from fruiting bodies and ECM tips was studied. The aim was to develop methods of propagating edible wild mushrooms and inoculating native forest plots with them in order to promote sustainable mushroom collection as an alternative for the diversification of family farming [21]. As part of this project, we have been conducting research and collecting fruiting bodies for several years, specifically targeting edible ECM mushrooms from these forests.…”

Native Andean–Patagonian Nothofagus forests harbour a unique diversity of microorganisms with diverse ecological roles. Although ectomycorrhizal associations constitute an important fragment of the biota associated with these forests, the factors affecting such communities are largely unknown. We investigated the biodiversity, relative abundance, and composition of ectomycorrhizal fungal communities in relation to two host tree species and ages and the soil properties in six monospecific and mixed evergreen–deciduous Nothofagus forests. We used the internal transcribed spacer (ITS2) region by sequencing 9,600 ectomycorrhizae (ECM) root tips for the identification of fungi. In total, 1,125 fungal taxa at the genus level distributed over 131 orders were identified. The phyla Ascomycota (34.5%) and Basidiomycota (62.1%) were the most abundant, whereas Mucoromycota (3.1%), Chytridiomycota, Cryptomycota, Olpidiomycota, and Zoopagomycota occurred less frequently. The highest taxon diversity was found in old trees, whereas young trees often exhibited a lower diversity of the associated fungi. The fungal taxa were grouped into seven broad ecological categories, of which saprotrophic associations were most common, followed by pathotrophic, pathotrophic–saprotrophic–symbiotrophic, pathotrophic–saprotrophic, and symbiotrophic associations. We did not detect significant differences in the number of taxa in each category between young and old N. dombeyi and N. obliqua. Overall, the scale of the Illumina sequencing approach allowed us to detect a fungal taxa diversity that would not be possible to find through surveys of fruiting bodies alone and that have never been observed in Nothofagus forests before. Our findings suggest the impact of the proximity between sites, the similarity of the soil conditions, and anthropogenic use of the forests on the belowground fungal community’s diversity and composition. Furthermore, there were differences between above- and belowground occurrences of the edible mushrooms B. loyo and Ramaria spp. However, future research, including on EMC tips found beneath fairy rings could provide significantly better correlations with the occurrence of aboveground fruiting body.
