Morphological characteristics have historically been used to study and identify Thai macrofungi, with many species being associated with those found in Europe and America. However, the lack of comprehensive herbarium collections, accurate descriptions, and molecular data has raised doubts on some of these conclusions, making them unconfirmable. The challenge of accurate macrofungal identification underscores the need for integrating both molecular and morphological data. Therefore, this review article is a part of the research project series “Revision and Update Checklist of Thai Macrofungi”. A new, accurate checklist of thirty genera viz. Amanita, Armillaria, Auricularia, Cacaoporus, Calocybella, Collybiopsis, Coniolepiota, Crinipellis, Cyathus, Erythrophylloporus, Gloeocantharellus, Heimioporus, Hymenagaricus, Inocybe, Lentinus, Lepiota, Macrolepiota, Marasmiellus, Panus, Paramarasmius, Parasola, Pseudosperma, Pyrenopolyporus, Retiperidiolia, Rhodactina, Rostrupomyces, Rubinosporus, Sutorius, Tuber, and Tulostoma, were revised and updated based on detailed specimen collections, description, and molecular data gathered from Thai specimens. This article contributes to the understanding of macrofungal diversity in Thailand by providing updated information on various genera, incorporating both morphological and molecular data, and highlighting their ecological significance within the diverse ecosystems.
