“…It is a cosmopolitan genus which has been reported in Australia , Brunei (Ho et al 2001), Chile (Shearer 1993), China (Tsui et al 2000, Cai et al 2002, France , Lesser Antilles (Zhang et al 2015), North America (Shearer 1993), Philippines (Cai et al 2003), South Africa and Thailand ). This paper is part of a study on the taxonomy and diversity of microfungi on substrates in freshwater, along a north-south latitudinal gradient from China through to New Zealand (Hyde et al 2016). The aim of this study is to introduce two new species of Helicascus, with descriptions and illustrations.…”

Two new Helicascus species H. chiangraiensis and H. uniseptatus from submerged wood in aquatic habitats in northern Thailand are introduced in this paper based on morphology and molecular analysis of DNA sequence data. Descriptions and illustrations of H. chiangraiensis and H. uniseptatus are provided. Helicascus chiangraiensis is characterized by its unilocular ascostromata, verrucose-walled ascospores with 2-4 large refractive guttules. Helicascus uniseptatus is characterized by its unilocular, small ascostromata, and uniseptate, smooth-walled ascospores lacking a mucilaginous sheath. Phylogenetic analysis based on combined ITS, LSU and TEF1α sequence data placed these species in Morosphaeriaceae (Pleosporales).

“…An extended sampling of lignicolous fungi from diverse aquatic ecosystems may reveal the diversity and dynamics of composition of these ecosystems. Habitat destruction and anthropogenic activities as well as global warming may impact on the diversity of fungal species and, therefore, aquatic fungi also are useful as ecological indicators (Hyde et al 2016). An understanding of the taxonomy of poorly studied taxa in aquatic environments will contribute to the knowledge of global biodiversity estimates and to updating regional checklists.…”

Helminthosporium species from submerged wood in streams in Yunnan Province, China were studied based on morphology and DNA sequence data. Descriptions and illustrations of Helminthosporium velutinum and a new species H. aquaticum are provided. A combined phylogenetic tree, based on SSU, ITS and LSU sequence data, place the species in Massarinaceae, Pleosporales. The polyphyletic nature of Helminthosporium species within Massarinaceae is shown based on ITS sequence data available in GenBank.

“…In this sense, it is known that macrofungi can be used as indicators of forest health (Laganà et al 2002), soil fertility (Kranabetter et al 2009), environmental pollution (Kubrová & Borovička 2015) and nature value (Marchetti 2004). Moreover, macrofungi have been documented to be affected by habitat loss (Halme et al 2013), forest fragmentation (Nordén et al 2013) and climate change (Boddy et al 2014;Hyde et al 2016).…”

A series of functional variables, including biomass and hymenial area, were obtained for more than 4800 individual macrofungal sporocarps and correlated with a set of ecological parameters characterizing soil, climate and forest structure in four different forest types of Costa Rica. The idea behind this project was to document macrofungi over a three-year period with the objective of generating a dataset intended to document sporocarp variability and association with forest characteristics. In the context of climate change, habitat degradation and tropical forest fragmentation, studying fungi from an ecological perspective can provide crucial elements of analysis to weigh their relevance in tropical systems and to understand the potential threats to fungal populations. Our results showed high variability in the functional variables over the period of study, but suggest that such variability is partially induced by macroclimatic events in which forests with a higher percentage of mycorrhizal fungi seemed to be more sensitive. Overall, the ratio of hymenial area/biomass and pileus diameter were found to be significantly correlated with several ecological parameters in the studied forest types. However, the association of the former with ecological reproductive strategies makes such variable a good parameter to use for the monitoring of fungal dynamics in the studied tropical forests. The potential application of the latter in the framework of climate change and forest degradation studies is relevant since fungi are essential organisms in tropical ecosystems.
