“…Species from Hebeloma form ectomycorrhizal associations with both angiosperms and gymnosperms in early development in disrupted habitats and mature forests (Nara et al, 2003). Garibay-Orijel et al (2013) reported that Hebeloma species possess a significant ecological importance in Pinus montezumae ecosystems because the genus was best manifested in spore banks from existing ectomycorrhizal fungi communities in the Trans-Mexican Volcanic Belt. Obase et al (2007) reported that H. mesophaeum was an important fungal species involved in the settlement of Pinus maximowiczii, Salix hultenii var.…”

“…We highlight the fact that the DNA sequences from S. brevipes and T. terrestris mycorrhizae found in peat moss and peat moss/vermiculite treatments in this study have greater similarities with Holarctic and Nearctic sequences than with sequences of mushroom vouchers from the TVB in central Mexico. Even when these species are known to form spore banks, they are not present in the spore banks in the TVB in central Mexico, while S. brunnea does (Garibay-Orijel et al 2013). This shows that the origin of the inoculum of S. brevipes and T. terrestris was not a contamination of the nursery from local air, as happened in the case of S. brunnea.…”

Sphagnum peat moss is one of the most commonly used substrates for forest plant and houseplant production. It is extracted from peat bogs in the circumboreal region and exported worldwide. Commercial peat moss is pasteurized, and is therefore believed to be free of viable ectomycorrhizal propagules. We used a bioassay with Pinus montezumae to demonstrate that commercial peat moss carries viable ectomycorrhizal spores, able to form mycorrhizae. Ectomycorrhizal fungi on seedling root-tips were sequenced for phylogenetic analyses using the ITS rDNA barcode region. We found three species: Suillus brevipes, Sphaerosporella brunnea, and Thelephora terrestris. S. brevipes and T. terrestris were found as viable inoculum transported in the peat moss, while S. brunnea was a greenhouse contaminant. S. brevipes and T. terrestris have biological characteristics (such as heat resistant and long living spores) that facilitate their survival to the extraction, transport, and storage processes of peat moss. This allows them to colonize nursery seedlings and to become potential invasive species in plantation areas. S. brevipes and T. terrestris are two of the most introduced fungi by anthropic activities; it has been argued that the vehicle for the introductions are their pine symbionts. This is the first time it has been demonstrated that peat moss is an important vehicle for the introduction of these fungi; a fact potentially related to the pattern of introduction of these ectomycorrhizal species from the northern hemisphere to elsewhere in the world.

“…Following incubation, 20 μL of dilution solution was added and the mixture incubated at ambient temperature for 30 min. 28 The ribosomal internal transcribed spacer (ITS) region was amplified with the primers and ITS1F and ITS4, 29 following the protocol of Izzo et al 30 The quality of the PCR products was reviewed by electrophoresis in 1% agarose gels. Good quality products were selected and cleaned using a mixture of 1 μL of ultrapure water and 1 μL of ExoSAP-IT (USB-Affimetrix) for each 3.5 μL of PCR product.…”

The present study conducted a genetic characterization and determined growth rate and biomass production in solid and liquid media, using strains obtained from wild edible sporomes of Lyophyllum that grow in high mountains. Vegetative isolation was used to obtain a total of four strains, which were divided into two clades within the section Difformia: Lyophyllum sp. and Lyophyllum aff. shimeji. Growth rate and biomass production were influenced by both the culture media and the strains. In a potato dextrose agar medium, the strains presented a higher growth rate, while in a malt extract-peptone and yeast agar medium, the growth rate was lower, but with a higher biomass production that was equal to that in the malt extract-peptone and yeast liquid medium.
