Freshwater Dothideomycetes
Bibliographic record
Abstract
Abstract Freshwater Dothideomycetes are a highly diverse group of fungi, which are mostly saprobic in freshwater habitats worldwide. They are important decomposers of submerged woody debris and leaves in water. In this paper, we outline the genera of freshwater Dothideomycetes with notes and keys to species. Based on multigene analyses and morphology, we introduce nine new genera, viz . Aquimassariosphaeria , Aquatospora , Aquihelicascus , Fusiformiseptata , Neohelicascus , Neojahnula , Pseudojahnula , Purpureofaciens , Submersispora ; 33 new species, viz . Acrocalymma bipolare , Aquimassariosphaeria kunmingensis , Aquatospora cylindrica , Aquihelicascus songkhlaensis , A. yunnanensis , Ascagilis submersa , A. thailandensis , Bambusicola aquatica , Caryospora submersa , Dictyocheirospora thailandica , Fusiformiseptata crocea , Helicosporium thailandense , Hongkongmyces aquaticus , Lentistoma aquaticum , Lentithecium kunmingense , Lindgomyces aquaticus , Longipedicellata aquatica , Neohelicascus submersus , Neohelicomyces dehongensis , N. thailandicus , Neohelicosporium submersum , Nigrograna aquatica , Occultibambusa kunmingensis , Parabambusicola aquatica , Pseudoasteromassaria aquatica , Pseudoastrosphaeriella aquatica , Pseudoxylomyces aquaticus , Purpureofaciens aquatica , Roussoella aquatica , Shrungabeeja aquatica , Submersispora variabilis , Tetraploa puzheheiensis , T. yunnanensis ; 16 new combinations, viz. Aquimassariosphaeria typhicola , Aquihelicascus thalassioideus , Ascagilis guttulaspora , A. queenslandica , A. seychellensis , A. sunyatsenii , Ernakulamia xishuangbannaensis , Neohelicascus aquaticus , N. chiangraiensis , N. egyptiacus , N. elaterascus , N. gallicus , N. unilocularis , N. uniseptatus , Neojahnula australiensis , Pseudojahnula potamophila ; 17 new geographical and habitat records, viz. Aliquandostipite khaoyaiensis , Aquastroma magniostiolata , Caryospora aquatica , C. quercus , Dendryphiella vinosa , Ernakulamia cochinensis , Fissuroma neoaggregatum , Helicotruncatum palmigenum , Jahnula rostrata , Neoroussoella bambusae , N. leucaenae , Occultibambusa pustula , Paramonodictys solitarius , Pleopunctum pseudoellipsoideum , Pseudocapulatispora longiappendiculata , Seriascoma didymosporum , Shrungabeeja vadirajensis and ten new collections from China and Thailand, viz. Amniculicola guttulata , Aquaphila albicans , Berkleasmium latisporum , Clohesyomyces aquaticus , Dictyocheirospora rotunda , Flabellascoma fusiforme , Pseudoastrosphaeriella bambusae , Pseudoxylomyces elegans , Tubeufia aquatica and T. cylindrothecia . Dendryphiella phitsanulokensis and Tubeufia roseohelicospora are synonymized with D. vinosa and T. tectonae , respectively. Six orders, 43 families and 145 genera which belong to freshwater Dothideomycetes are reviewed. Of these, 46 genera occur exclusively in freshwater habitats. A world map illustrates the distribution of freshwater Dothideomycetes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
