    Abstract
    Fungal taxonomy has undergone a transformation in recent decades, propelled by the advent of molecular methodologies that have fundamentally reshaped traditional morphology-based species delineation. This paper examines the progression of fungal classification systems, with a focused discussion on integrative taxonomic frameworks, including Genealogical Concordance Phylogenetic Species Recognition (GCPSR) and coalescent-based methods. These molecular advancements have revealed extensive cryptic diversity, as exemplified by revisions within the Colletotrichum gloeosporioides species complex. While DNA barcoding—particularly through the Internal Transcribed Spacer (ITS) region—has accelerated species discovery, the potential for taxonomic inflation highlights the need for robust multilocus and population-genetic analyses. The conceptualization of “new” fungal species is critically evaluated through an eco-evolutionary lens, emphasizing the imperative for a multidisciplinary synthesis of molecular, morphological, and ecological data. Furthermore, this paper emphasizes the importance of equitable global access to molecular technologies and infrastructural resources, particularly in biodiverse yet under-resourced regions such as India. Such inclusivity is vital to fostering broader engagement in fungal systematics and ensuring more comprehensive biodiversity assessment and conservation efforts.
