“…Brazil has many species of Ingoldian fungi that are also reported from other tropical countries such as Malaysia (Nawawi 1985b) and Puerto Rico (Santos-Flores & Betancout-López 1997), and tropical to subtropical areas of India , Sudheep & Sridhar 2013. These countries share genera like Condylospora Nawawi (1976: 363), Flabellospora Alas.…”

Ingoldian fungi of Brazil: some new records and a review including a checklist and a key

Ingoldian fungi have a worldwide distribution, but the most species have been described from temperate regions. In Brazil, the studies of Ingoldian fungi started in the 1980’s in the Atlantic Forest, the state of São Paulo. Later studies extended to other biomes such as the Cerrado, Caatinga and Amazon. The aim of this study is to improve our understanding of the occurrence and distribution of Ingoldian fungi in Brazil. Here, we include and discuss several new records for Brazil associated with submerged leaves of Calophyllum brasiliense and provide a checklist, a key and illustrations for all species of the Ingoldian fungi recorded from Brazil, as well as distribution maps. Flagellospora stricta is a new record to the Americas; Dendrosporomyces prolifer and Geniculospora inflata to the Neotropics; Pyramidospora casuarinae and Triscelophorus monosporus are new records to the Caatinga. With the new additions of species associated with submerged leaves of C. brasiliense, a total of 85 taxa of Ingoldian fungi are now recorded in Brazil. Nineteen taxa are reported from the Amazon, 53 from the Atlantic Forest, 39 from the Caatinga and 21 from the Cerrado.

First records of Ingoldian fungi from the Brazilian Amazon

Ingoldian fungi play an important ecological role by active participation in the decomposition of submerged leaves in aquatic ecosystems. These fungi produce conidia that are filiform, tetraradiate, multiradiate, scolecoid or sigmoid, which aid in the adaptation and dispersal in freshwater habitats. Despite their important ecological role in freshwater there have been no taxonomic and distributional studies of these fungi in the Brazilian Amazon. The aim of this study was to report new records of Ingoldian fungi to Americas, Brazil and Brazilian Amazon region. The fungal specimens were obtained from natural foam, found on the surface of streams in the ''Reserva Ducke'' (municipality of Manaus) and the ''Balnea ´rio Marupiara'' (municipality of Presidente Figueiredo) in Amazonas state, Brazil. The foam samples were transferred to slides and completely evaporated at room temperature. Lactic acid was added to the slides and covered using a glass cover slip and sealed with nail polish. Seventeen taxa were recorded. All identified taxa are new records: one new to the Americas (Tricladium curvisporum Descals), three new to Brazil (Condylospora flexuosa Nawawi and Kuthub., C. spumigena Nawawi and Dwayaangam cornuta Descals), and 13 new to the Brazilian Amazon region. Our study provides baseline data on the species composition of Ingoldian fungi from the Brazilian Amazon region, thereby enhancing the knowledge of aquatic mycology in this biodiversity hotspot. Descriptions, illustrations, geographical distribution patterns and comments are presented for all observed species.

“…The question remains to understand the pattern of fungal assemblage and leaf litter decomposition in tree canopies in comparison to the stream ecosystem. There are a few detailed studies on leaf litter decomposition in the Indian streams (Raviraja et al 1996(Raviraja et al , 1998Sridhar et al 2011;Sudheep & Sridhar 2013). The primary objective of this study was to investigate the structure and function of aquatic hyphomycete assemblages in riparian tree holes and to compare it with that of a second-order stream in the south-west coast of India during monsoon season.…”

Fungal assemblage and leaf litter decomposition in riparian tree holes and in a coastal stream of the south-west India

2013

Assemblage of aquatic hyphomycetes and decomposition of banyan leaf litter (Ficus benghalensis) were assessed in riparian tree holes and in a tropical coastal stream during rainy season up to 8 weeks in southwest coast of India. Although fungal assemblage was similar, leaf decomposition and leaf chemical changes differed between tree holes and the stream. Out of the 18 aquatic hyphomycetes, 17 were common on leaf litter in tree holes and the stream. Anguillospora longissima, Flagellospora curvula, Lunulospora curvula, Triscelophorus acuminatus and T. konajensis were the top five species in tree holes and the stream. The species richness was the highest during the second week in tree holes (11 species) and the sixth week in the stream (14 species), while the conidial output was the highest in tree holes and the stream during sixth week. The daily decay coefficient (k) was significantly faster in streams than in tree holes. Mass loss of banyan leaves between tree holes and the stream was positively correlated with conidial output by the aquatic hyphomycetes. The estimated half-life (t 50) of leaf decomposition ranged between 70 days (stream) and 128 days (tree holes). Organic carbon in leaf litter gradually decreased, while nitrogen content decreased up to 1-2 weeks and then gradually increased over the incubation period. Ergosterol showed a gradual increase in tree hole litter, while it attained its peak in 4 weeks and declined thereafter in the stream litter. Loss of phosphorus concentration was rapid in the stream than in tree holes. Total phenolics concentration in leaves decreased rapidly in the stream than in tree holes. However, low dissolved oxygen in water and the slow release of phenolics from the leaf litter showed negative impact on the fungal activity and the rate of leaf decomposition in tree holes.
