Checklist of the agaricoid and similar morphology mycobiota of Paraíba State, Brazil

- (Checklist of the agaric mycobiota and similar morphology of Paraíba State, Brazil). Brazil has a rich biodiversity, but many species remain to be discovered, studied and cataloged. In the Paraíba State, taxonomy studies on agaric fungi are still infrequent. Thus, this present work carried out a bibliographic review of fungal species belonging to orders Agaricales, Boletales, Cantharellales, Gomphales and Russulales from the Paraíba State previously described or mentioned, because the knowledge about the fungal diversity in the region still remain disaggregated and poorly known. Thus, we organize and present information about the geographic distribution of the taxa in this checklist format. For the compilation of the results, for each species we present the published herbarium numbers and their respective citations. As results, we found 79 taxa belonging 41 genera, 22 families and five orders occurring in areas of the Atlantic Forest and Caatinga. So, this review is extremely important for the dissemination of the valuation of the State’s biodiversity providing information about our Brazilian biomes.

The objective of this work is to perform a bibliographic overview of agaric fungi of Paraíba State, for improve the current status of knowledge of this group of fungi in this region.This knowledge is essential for instruct and raise awareness about the importance of the biological conservation in ecosystems and the self-sustainability (Lodge et al. 1995, Straatsma et al. 2001).

Materials & Methods
The Paraíba State (figure 1) is localized at the Northeastern region of Brazil and occupies an area of 56,372 km², corresponding to less than 1% of the national territory (Francisco et al. 2015).The geographical relief is diversified, with parts with humid, subhumid and semiarid climates.
For the elaboration of the map, we use Google Earth™.For the species compilation we performed a bibliographic survey in which the species are presented with their citation and region of the State where the materials were collected, including respective herbarium voucher's deposit.When the authors did not inform herbarium number, we consulted the INCT-Virtual Herbarium of Flora and Fungi website (https://specieslink.net/).If we do not find the herbarium code and number, we inform the collection number and the herbarium acronym where supposedly the material is deposited [e.g., Singer B 3341 (BAFC, LIL), M.A. Neves 412 (FLOR), A.N.M. Furtado 32 (FLOR) and other].Taxonomic position of the generic names is based in He et al. (2019), Kalichman et al. (2020) and Wijayawardene et al. (2020).Epithets and species authority are based in Mycobank (Crous et al. 2004, Robert et al. 2113).Herbaria codes follow Thiers (continuously updated), except for UFRN-Fungos (Departamento de Botânica e Zoologia, Universidade Federal do Rio Grande do Norte).
After survey of 30 works (including article, books and books chapters) we found 79 taxa belonging to 41 genera, 22 families and five orders (figure 2, table 1), collected from eight areas belonging six municipalities:    1).Most of these specimens are deposited at JPB, but also in the herbaria of BAFC, F, FLOR, LIL, UFRN-Fungos and URM.In João Pessoa were recorded at least two well delimited areas, UFPB Campus I and Jardim Botânico Benjamin Maranhão.All species published by Singer (1961Singer ( , 1965Singer ( , 1966Singer ( , 1973aSinger ( , 1973bSinger ( , 1976Singer ( , 1977) ) were delimited only with the city's name (table 1), and no exact locality was able to be informed.In Mataraca, it was recorded a mining currently named 'Tronox'.
Regarding to genera, Marasmius was the genus with the most species recorded for the state.We found 10 species cited or described (table 1).The genus comprises about 600 worldwide known species, most of them saprophytic (He et al. 2019, Wijayawardene et al. 2020), and recent studies referred 49 taxa, mostly from Atlantic Forest of Southeastern Brazil (e.g.Oliveira et al. 2014Oliveira et al. , 2020aOliveira et al. , 2020b)).The genus is considered a key component in the tropical mycobiota, due to the importance in decomposing leaf litter in forest by the networks of rhizomorphs that facilitate the trap litter (Lodge & Cantrell 1995), and plays an important role in the nutrient cycle (Braga-Neto et al. 2008).

General remarks and conclusion
In Paraíba State, Magnago et al. (2013) cited 22 names of agaricoid species from the semiarid and Magnago et al. (2015) 18 species from the Atlantic Forest.However, some names published by them need to be re-analyzed for a more accurate identification.As an example, we can mention the material identified as Coprinus xerophilus Bogart by Magnago et al. (2013) which currently corresponds to C. calyptratus Peck (Gomes & Wartchow 2018).Thus, most of the names reported may be a misapplication of European species names and need to be revised.For this reason, we have included all information as possible of the collection data for each name.
Taxonomic knowledge about agaricoid fungi in Brazil is still little understood, requiring more specific researches and focus in this group of macrofungi, and also among other diverse groups of the Kingdom Fungi.
In order to increase the knowledge about the high biodiversity of macrofungi belonging to this group in the Paraíba State, it is essential to have as a basis the research and revision of information on studies already carried out, making a survey of species already found and cataloged.We did not find studies published on ecological aspects of agaricoid fungi from Paraíba State.This is due to the lack of investment in research in the state, resulting in the scarcity of information of fungal species in the region.
