Plant and fungus systematics and taxonomy constitute foundational disciplines that underpin our understanding of biodiversity. Historically grounded in morphological and anatomical studies, these ...

Three species which contain both gyrophoric and lecanoric acids and possess perithecioid ascomata are recognized in the genus Diploschistes. D. badius and D. gyrophoricus are described as new, while D ...

The argument is made that species should be comparable with respect to the numbers of genotypes they include, regardless of whether their reproduction is exclusively sexual or not. Specifically, this ...

Our research focuses on understanding the nature of plant speciation and diversification using a variety of approaches. We use molecular phylogenetics to test ideas of species relationships, taxonomy, ...
