Mycology was a well-studied discipline in Australia and New Zealand, Europe, South Africa and the USA. In Asia (with the exception of Japan) and South America, the fungi were generally poorly known and studied, except for the result of forays from some American and European mycologists. However, in the last 20 years, the situation has changed. With...

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...

Inaccurate taxonomic placement of fossils can lead to the accumulation of errors in molecular clock studies and their generated evolutionary lineages. There are limited fossil data that can be used in divergence time estimations. Therefore, reliable morphological characterization and taxonomical identification of fossil fungi are extremely importan...

Fungi have been often neglected, despite the fact that they provided penicillin, lovastatin and many other important medicines. They are an understudied, but essential, fascinating and biotechnologically useful group of organisms. The study of fungi in northern Thailand has been carried out by us since 2005. These studies have been diverse, ranging...

The advantages and disadvantages of giving a valid name to a sequence of DNA detected from environmental specimens is presently a hot debate amongst the mycological community. The idea of using intracellular DNA (‘‘mgDNA’’) from environmental samples as holotypes seems at face value, to be a good idea, considering the expansion of knowledge among t...
