Fungi play an important role in litter decomposition in forest ecosystems and are considered an undersampled group in the Amazon biome. This study aims to describe the composition, richness and frequency of species of conidial fungi associated with palm trees in an area of the Amapá National Forest, State of Amapá, Brazil. Palm leaf litter was collected from July 2009 to June 2010, incubated in moist chambers and examined for the presence of fungi. One hundred and seven species of conidial fungi were identified, in 79 genera and 25 families. As for the relative frequency of the species, the majority (94.4%) was sporadic and occurred on leaflets. We report new records for South America (Chaetopsis intermedia, Chaetochalara laevis and Thysanophora verrucosa) and Brazil (Chloridium phaeosporum, Helminthosporiella stilbacea and Zygosporium geminatum), and 83 for the State of Amapá, while 15 are also new for the Brazilian Amazon. This study significantly increases the knowledge about the distribution of the fungal species in the Amazon biome, and emphasizes the importance of the conservation of these organisms particularly in view of the large number of sporadic species recorded.

“…The investigation on conidial fungi associated with the decomposition of palm leaves in the Amazon rainforest has been restricted to three areas, namely the National Forest of Caxiuanã [274,387,[477][478][479][480][481] and the Combu Island [482,483] in Pará, and the National Forest of Amapá in Amapá [264,387,479,481]. Several Arecaceae hosts have been sampled, including members of Astrocaryum, Attalea, Bactris, Euterpe, Geonoma, Maximiliana, Oenocarpus, Socratea, and Syagrus.…”

Over the past three decades, a wealth of studies has shown that palm trees (Arecaceae) are a diverse habitat with intense fungal colonisation, making them an important substratum to explore fungal diversity. Palm trees are perennial, monocotyledonous plants mainly restricted to the tropics that include economically important crops and highly valued ornamental plants worldwide. The extensive research conducted in Southeast Asia and Australasia indicates that palm fungi are undoubtedly a taxonomically diverse assemblage from which a remarkable number of new species is continuously being reported. Despite this wealth of data, no recent comprehensive review on palm fungi exists to date. In this regard, we present here a historical account and discussion of the research on the palm fungi to reflect on their importance as a diverse and understudied assemblage. The taxonomic structure of palm fungi is also outlined, along with comments on the need for further studies to place them within modern DNA sequence-based classifications. Palm trees can be considered model plants for studying fungal biodiversity and, therefore, the key role of palm fungi in biodiversity surveys is discussed. The close association and intrinsic relationship between palm hosts and palm fungi, coupled with a high fungal diversity, suggest that the diversity of palm fungi is still far from being fully understood. The figures suggested in the literature for the diversity of palm fungi have been revisited and updated here. As a result, it is estimated that there are about 76,000 species of palm fungi worldwide, of which more than 2500 are currently known. This review emphasises that research on palm fungi may provide answers to a number of current fungal biodiversity challenges.

Three asexual fungi are described and illustrated from the Brazilian Amazon:Vesiculophora diversiseptata as a new genus and species; and Anapleurothecium clavatum and Podosporium simile as new species. Vesiculophora diversiseptata is characterized by its conidiophores becoming scorpioid after successive subacroauxic extensions and monoblastic conidiogenous cells that produce heteroseptate, brown phragmoconidia; A. clavatum is distinguished by its ellipsoidal to clavate, 3-euseptate, brown conidia; and P. simile is characterized by its synnematous conidiomata with monotretic conidiogenous cells and brown, 3–11-eusepatate, mainly obclavate, verrucose conidia. Additionally, Pleurothecium leptospermi is transferred to Anapleurothecium.
