Tropical Australian Freshwater Fungi XIII. A new species of Anthostomella and its sporodochial Geniculosporium anamorph

Authors:

Abstract

Submerged wood collected in creeks in north Queensland, Australia yielded a new species of Anthostomella. A sporodochial Geniculosporium anamorph was associated with the ascomata on the wood surface. Single, ascospore isolations formed colonies typical of the Xylariaceae and conidia identical to those produced on the wood surface. Anthostomella species were previously unknown from submerged wood. Anthostomella aquatica sp. nov. and its anamorph, Geniculosporium sporodochiale sp. nov., are described in this paper. The fungus has also been collected on submerged wood at other sites in north Queensland, Brunei, Hong Kong and South Africa.
... A nodulisporium-like asexual morph was produced in culture of Anthostomella trachycarpi S.M. Francis and a virgariella-like asexual morph, which is also a form of nodulisporium-like asexual morph from culture of Anthostomella baileyi S.M. Francis (Francis et al. 1980). Hyde and Goh (1998) described Geniculosporium sporodochiale K.D. Hyde & Goh, as the asexual morph of the freshwater species Anthostomella aquatica K.D. Hyde & Goh. This indicates that Anthostomella is polyphyletic and should comprise several genera in Xylariaceae, as taxa have asexual morphs typical of genera in both Hypoxyloideae and Xylarioideae. ...

Anthostomella has long been regarded as a large, but polyphyletic genus in the family Xylariaceae, but species in this group generally lack phylogenetic data. In this study, 14 anthostomella-like taxa collected from Italy, were studied using both morphology and molecular data. Single ascospore isolates were obtained and the asexual morphs of five taxa established. The phylogenetic relationships of the xylariaceous taxa were inferred using combined ITS, RPB2, β tubulin and LSU gene regions.We introduce new sequence data for 24 with included the 14 new anthostomella-like taxa. The subfamilies Hypoxyloideae and Xylarioideae within Xylariaceae were recognized as the two major clades with high bootstrap support. Within the two clades 21 subclades were resolved and the anthostomella-like taxa clustered in five of these subclades indicating that the genus is polyphyletic. Anthostomella sensu stricto comprised A. forlicesenica, A. formosa, A. helicofissa, A. rubicola and A. obesa. The A. formosa and A. rubicola collections morphologically closely resemble the type specimens and therefore we designate reference specimens. Three new species Anthostomella helicofissa, A. forlicesenica and A. obesa are also introduced. Four distinct lineages of anthostomella-like taxa correspondent to four new genera, Anthocanalis, Brunneiperidium, Lunatiannulus and Pyriformiascoma, which are also introduced, while one clustered in Astrocystis and is introduced as a new species. Keys to the new anthostomella-like genera and species examined in this study are provided

A comprehensive account of fungal classification from freshwater habitats is outlined and discussed in the present review based on literature of biodiversity studies and recent morpho-phylogenetic analyses. A total of 3,870 freshwater fungal species are listed with additional details on the isolation source, habitat, geographical distribution, and molecular data. The Ascomycota (2,968 species, 1,018 genera) dominated the freshwater fungal taxa wherein Sordariomycetes (823 species, 298 genera) had the largest number, followed by Dothideomycetes (677 species, 229 genera), Eurotiomycetes (276 species, 49 genera), and Leotiomycetes (260 species, 83 genera). Other phyla included in the updated classification of freshwater fungi are: Chytridiomycota (333 species, 97 genera), Rozellomycota (221 species, 105 genera), Basidiomycota (218 species, 100 genera), Blastocladiomycota (47 species, 10 genera), Monoblepharomycota (29 species, 6 genera), Mucoromycota (19 species, 10 genera), Aphelidiomycota (15 species, 3 genera), Entomophthoromycota (6 species, 4 genera), Mortierellomycota (5 species, 3 genera), Olpidiomycota (4 species, 1 genus), Zoopagomycota (3 species, 2 genera), and Sanchytriomycota (2 species, 2 genera). The freshwater fungi belong to 1,361 genera, 386 families and 145 orders. The Pleosporales and Laboulbeniaceae are the largest freshwater fungal order and family comprised of 391 and 185 species, respectively. The most speciose genera are Chitonomyces (87, Laboulbeniomycetes), Verrucaria (50, Eurotiomycetes), Rhizophydium (52, Rhizophydiomycetes), Penicillium (47, Eurotiomycetes), and Candida (42, Saccharomycetes).

Sordariomycetes is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi mainly characterized by perithecial ascomata and inoperculate unitunicate asci. Freshwater Sordariomycetes play an important role in ecosystems and some of them have the potential to produce bioactive compounds. This study documents and reviews the freshwater Sordariomycetes, which is one of the largest and important groups of fungi in aquatic habitats. Based on evidence from DNA sequence data and morphology, we introduce a new order Distoseptisporales, two new families, viz. Ceratosphaeriaceae and Triadelphiaceae, three new genera, viz. Aquafiliformis, Dematiosporium and Neospadicoides, 47 new species, viz. Acrodictys fluminicola, Aquafiliformis lignicola, Aquapteridospora fusiformis, Arthrinium aquaticum, Ascosacculus fusiformis, Atractospora aquatica, Barbatosphaeria lignicola, Ceratosphaeria aquatica, C. lignicola, Chaetosphaeria aquatica, Ch. catenulata, Ch. guttulata, Ch. submersa, Codinaea yunnanensis, Conioscypha aquatica, C. submersa, Cordana aquatica, C. lignicola, Cosmospora aquatica, Cylindrotrichum submersum, Dematiosporium aquaticum, Dictyochaeta cangshanensis, D. ellipsoidea, D. lignicola, D. submersa, Distoseptispora appendiculata, D. lignicola, D. neorostrata, D. obclavata, Hypoxylon lignicola, Lepteutypa aquatica, Myrmecridium aquaticum, Neospadicoides aquatica, N. lignicola, N. yunnanensis, Ophioceras submersum, Peroneutypa lignicola, Phaeoisaria filiformis, Pseudostanjehughesia lignicola, Rhodoveronaea aquatica, Seiridium aquaticum, Sporidesmiella aquatica, Sporidesmium lageniforme, S. lignicola, Tainosphaeria lunata, T. obclavata, Wongia aquatica, two new combinations, viz.

This is the first in a series of papers on lignicolous freshwater fungi from China. In this paper, eight fresh collections of taxa of Dictyosporiaceae from submerged wood in freshwater are characterized based on morphological characters and phylogenetic analyses of combined ITS, LSU and TEF1α sequence data. A new monotypic genus Aquadictyospora, with A. lignicola as the type species is introduced based on its distinct morphology and evidences from molecular phylogeny. In addition, detailed description and illustration of Pseudodictyosporium wauense from the fresh collection are provided and it is a new record for China.

In this essay, we focus on the micro-xylariaceous genera (with inconspicuous ascomata and asexual morphs) in the Xylariomycetidae, with special emphasis on Xylariaceae. Are micro-xylariaceous less diverse than macro-xylariaceous genera (with conspicuous stromata) genera? This paper also reviews their taxonomic significance and current systematic relationship and evaluates different characters used in their taxonomic placement. So far, only a few micro-xylariaceous taxa have been studied in detail in comparison with the stromatic macroscopic xylariaceous taxa and the reasons for this are discussed. It is hoped that further sampling and study of different substrata and habitats, with greater emphasis on sequence data, may lead to the discovery of many more micro-xylariaceous genera.
