Grasses are cosmopolitan yet an important component in ecology. The current human population readily relies on grasses as many Poaceae species provide staple carbohydrate sources and staple feed to livestock. Ecologically grass plays a vital role as a pioneer inhabitant as well as sustaining immense biodiversity within the community. Fungi play a p...

In plant pathology, the correct naming of a species is essential for determining the causal agents of disease. Species names not only serve the general purpose of concise communication, but also are critical for effective plant quarantine, preventing the introduction of new pathogens into a territory. Many phytopathogenic genera have multiple speci...

Grasslands are major primary producers and function as major components of important watersheds. Although a concise definition of grasslands cannot be given using a physiognomic or structural approach, grasslands can be described as vegetation communities experiencing periodical droughts and with canopies dominated by grasses and grass-like plants....

Thailand is rich in fungal diversity and new taxa are continuously introduced. In the last decade there has been a vast improvement on the taxonomy, phylogeny and classification of fungi, including in Thailand. Earlier studies were solely based on morphology while modern research uses morphology and molecular phylogeny. There is a huge gap between...

Fungi are an understudied, biotechnologically valuable group of organisms. Due to the immense range of habitats that fungi inhabit, and the consequent need to compete against a diverse array of other fungi, bacteria, and animals, fungi have developed numerous survival mechanisms. The unique attributes of fungi thus herald great promise for their ap...

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10–15 years, and continues to accelerate.
