SUMMARY:

: Fungi are key elements in maintaining the environments on our planet, due to their essential role in decomposition and nutrient cycling in ecosystems. Brazil has a wide mycological diversity and has two biomes (Cerrado and Atlantic Forest) that are considered biodiversity hotspots. The country has been suffering intense losses due to deforestation and the increase in human-altered areas, threatening the species found in these habitats. The genus Cyathus Haller, present in the Nidulariaceae family, is characterized by having a shape similar to a cone or an inverted bell, with disc-shaped structures arranged internally. It is widely distributed in Brazil, occurring in almost all biomes. Previously, it was believed that the species of this group did not occur in certain regions, however, this occurred due to the lack of specialists and incorrect identification of specimens of other genera. In this scenario, this study sought to collect samples from strategic locations to increase data on this group and reevaluate samples at the genus level or with incomplete data, in addition to understanding the diversity of the genus through the analysis of materials deposited in biological collections. The most current morphological characters proposed in recent articles were used to describe and delimit the analyzed materials. From the analysis of 114 materials, it was possible to observe an increase in the number of species deposited in the UFRN-FUNGOS and UFSC-FLOR collection, from materials that were only at the genus level or unidentified. Some of these species had only a single known record or no records for some regions of Brazil. With this, it was possible to expand knowledge of the group in regions with scarcity of information, such as Acre, Ceará, Paraíba, Roraima, Rio Grande do Norte and Santa Catarina. A new record of the species Cyathus badius, for the country of Cameroon. In addition, 3 possible new species were identified. With the studies, it was possible to establish a standard for better conservation of these specimens in the collections, with the aim of promoting better herborization conditions of the deposited materials.
