“…Sordariomycetes also was the most recovered class from aquatic environments from Mexico and the other classes like Saccharomycetes, Eurotiomycetes. Leotiomycetes, Dothideomycetes, Sordariomycetes, Tremellomycetes and Chytridiomycetes also were observed in this study (Valderrama et al 2016). Microbotryomycetes are Basidiomycete yeasts common to aquatic environments like mangroves.…”

“…Members of this Phylum generally decompose cellulose selectively over lignin (Osono 2007) and dominate the fungal community and are highly active (production of extracellular enzymes) in the early stages of litter decomposition (Zhang et al 2018). Aquatic ascomycetes play important roles in wood and leaf litter degradation since basidiomycetes are found in lower quantities (Valderrama et al 2016). Ascomycetes appear to be better able to withstand the conditions prevailing in aquatic habitats, far more than basidiomycetes (Jones and Choeyklin 2007).…”

“…Besides, the metabolic versatility of this microorganisms allows them to exploit many different niches which renders them as significant components of these ecosystems, acting as decomposers, mutualists, and pathogens (Schmit and Mueller 2007). However, despite the diversity of approximately 1.5 million species (Hawksworth, D L 2004), we have identified a minority of these species (Schmit and Mueller 2007) and even less in marine habitats (Valderrama et al 2016).…”

Leaf decomposition is the primary process in release nutrients in the dynamic mangrove habitat, supporting the ecosystem food webs. On most environments, fungi are an essential part of this process. However, due to the peculiarities of mangrove forests, this group is currently neglected. Thus, this study tests the hypothesis that fungal community display an specific succession pattern in different mangrove species. A molecular approach was employed to investigate the dynamics of the fungal community during the decomposition of three common plant species (Rhizophora mangle, Laguncularia racemosa, and Avicennia schaueriana) from the mangrove habitat located at the southeast of Brazil. Plant material was the primary driver of fungi communities but time also was marginally significant for the process, and evident changes in the fungal community during the decomposition process were observed. The five most abundant classes common to all the three plant species were Saccharomycetes, Sordariomycetes, Tremellomycetes, Eurotiomycetes, and Dothideomycetes, all belonging to the Phylum Ascomycota. Microbotryomycetes class were shared only by A. schaueriana and L. racemosa, while Agaricomycetes class were shared by L. racemosa and R. mangle. The class Glomeromycetes were shared by A. schaueriana and R. mangle. The analysis of the core microbiome showed that Saccharomycetes was the most abundant class. In the variable community, Sordariomycetes was the most abundant one, mainly in the Laguncularia racemosa plant. The results presented in this work shows a specialization of the fungal community regarding plant material during mangrove litter decomposition.

“…Those were registered in the Pacific ocean. 7 Members of this phylum are zoosporic fungi that use a monocentric thallus as anucleate filamentous rhizoids to anchor the substrate absorb their nutrients. They are saprophytes, pathogens and can degrade chitin, cellulose, and keratin.…”

“…1 The studied fungi were isolated from coastal water and foam, sand beach, detritus, mangrove wood, and rhizosphere. [2][3][4][5][6][7][8][9][10][11][12][13] Gonzalez et al, 3 reported the last checklist of marine fungi in México, where it contained sixtyone ascomycetes and one basidiomycete, all of them isolated by culture. Since then, only ten papers on marine fungi in México have been published.…”

Marine fungi are essential as recyclers of organic matter in the ocean, as well their secondary metabolites are now studied as potential drugs for different diseases. Despite Mexico having an extensive coastline, few resources have been allocated to the research of this group. Through a thorough review of scientific literature between 2001 and February 2021, a systematic listing of marine fungi on Mexico's marine waters was constructed. In this work, two orders, forty-nine genera, and thirteen species are recorded, of which 50 are new records. The most frequent phylum was Ascomycota (92%; 50 genera), followed Chytridiomycota (4%; 2 genera) and Basidiomycota (4%; 2 genera). Most of them have been reported in the Gulf of Mexico, followed by the Pacific Ocean, Gulf of California and, the Caribbean. A new halophile species isolated from deep sediment in the Gulf of California (Aspergillus loretoensis) is also reported.

Leaf decomposition is the primary process in release of nutrients in the dynamic mangrove habitat, supporting the ecosystem food webs. On most environments, fungi are an essential part of this process. However, due to the peculiarities of mangrove forests, this group is currently neglected. Thus, this study tests the hypothesis that fungal communities display a specific succession pattern in different mangrove species and this due to differences in their ecological role. A molecular approach was employed to investigate the dynamics of the fungal community during the decomposition of three common plant species (Rhizophora mangle, Laguncularia racemosa, and Avicennia schaueriana) from a mangrove habitat located at the southeast of Brazil.

In the variable community, Sordariomycetes was the most abundant one, mainly in the Laguncularia racemosa plant. The results presented in this work shows a specialization of the fungal community regarding plant material during litter decomposition which might be related to the different chemical composition and rate of degradation.
