BACKGROUND The Sierra Madre Occidental of Chihuahua in Northern Mexico is inhabited by indigenous Raramuris, mestizos, and other ethnic groups. The territory consists of canyons and ravines with pine, oak and pine-oak forests in the higher plateaus. A great diversity of potentially edible mushrooms is found in forests of the Municipalities of Bocoyna and Urique. Their residents are the only con...

An ETAAS method was validated to quantify total Cr and Cr(VI) in mushrooms and the underlying soils. The method includes a sample pretreatment for total Cr dissolution using a wet acid digestion procedure and a selective alkaline extraction for Cr(VI). The limits of detection were, expressed in microg/L, 0.15 and 0.17 for total Cr and Cr(VI), respectively. The linearity ranges under the optimiz...

Molecular approaches have become an important tool for mycologists studying fungal systematics, molecular evolution, population genetics or plant-fungus interactions. For this purpose the analysis of restriction fragment length polymorphisms (RFLPs), PCR-based techniques like amplification of polymorphic sequences by one random primer (RAPDs) or amplification of defined genomic regions are appl...

Invasive alien species are species introduced deliberately or unintentionally to areas outside their natural habitats. They can cause a significant irreversible environmental and socio-economic impact at genetic, species and ecosystem levels, and as claimed by Moore (2000), ‘throughout the world, exotic aliens are wreaking havoc’. The control of these invasive alien species has been discussed a...

Madagascar is known for its high diversity and endemism of fauna flora. Fungi, however, have been largely overlooked in evolution studies on the island, whether fungi exhibit same patterns as animals plants has yet to be further examined. We collected fungal sporocarps ectomycorrhizal (EcM) roots during three opportunistic surveys five forests generated a dataset Internal Transcribed Spacer (IT...

Article 23.1 of the Code (Turland & al. in Regnum Veg. 159. 2018) rules that a specific epithet may have one three forms: “an adjective, noun genitive, or word apposition”. Of these three, “a apposition” is likely to be least clear modern reader, partly because declining familiarity with Latin among botanists, but also they often do not stand out as being this category. Upon taking closer look,...
