Four new species and two new Chinese records of the genus Oncopodiella are reported. The new species are O. obovata, O. diospyricola, O. obliqua and O. fusiformis. New records for China are O. trigonella and O. robusta. The six species were all collected on saprobic substrata. A key to all known species of Oncopodiella is proposed. Specimens of the...

Oncopodiella possesses macronematous, mononematous, subhyaline to pale brown conidiophores, polyblastic, sympodial conidiogenous cells with cylindrical denticles and dematiaceous, muriform, corniculate conidia in various shapes (trigonous, turbinate, subglobose, ellipsoidal, obovoid, pyriform and fusiform or irregular) with hyaline or subhyaline horned, protruding cells (Rifai 1965;Ellis 1971;Zhao and Zhang 2005b;Magyar and Révay 2009 Notes: Attempts to preserve the living culture were unsuccessful since few conidia germinated, with no growth after reaching 1-2 mm diam. ...
... It was reported mainly from Europe including Belgium, Great Britain, France, Hungary, Italy, Lithuania and Spain, and also from Asia in Iran and China. This species frequently occurs on bark, dead branches, leaves and plant debris and is encountered in rainwater, honey and water-filled tree holes and is reported as air spores in an Italian vineyard (Rifai 1965;Kirk 1983;Révay 2003, 2004;Zhao and Zhang 2005b;Gharizadeh et al. 2007;Magyar and Révay 2009;Magyar et al. , 2016Rambelli et al. 2010;Kutorga et al. 2013; Hernández-Restrepo Notes: Chaetothyriales belongs to Chaetothyriomycetidae in Eurotiomycetes and comprises ten families .

Freshwater fungi comprises a highly diverse group of organisms occurring in freshwater habitats throughout the world. During a survey of freshwater fungi on submerged wood in streams and lakes, a wide range of sexual and asexual species were collected mainly from karst regions in China and Thailand. Phylogenetic inferences using partial gene regions of LSU, ITS, SSU, TEF1α, and RPB2 sequences revealed that most of these fungi belonged to Dothideomycetes and Sordariomycetes and a few were related to Eurotiomycetes. Based on the morphology and multi-gene phylogeny, we introduce four new genera, viz. Aquabispora, Neocirrenalia, Ocellisimilis and Uvarisporella, and 47 new species, viz. Acrodictys chishuiensis, A. effusa, A. pyriformis, Actinocladium aquaticum, Annulatascus tratensis, Aquabispora setosa, Aqualignicola setosa, Aquimassariosphaeria vermiformis, Ceratosphaeria flava, Chaetosphaeria polygonalis, Conlarium muriforme, Digitodesmium chishuiense, Ellisembia aquirostrata, Fuscosporella atrobrunnea, Halobyssothecium aquifusiforme, H. caohaiense, Hongkongmyces aquisetosus, Kirschsteiniothelia dushanensis, Monilochaetes alsophilae, Mycoenterolobium macrosporum, Myrmecridium splendidum, Neohelicascus griseoflavus, Neohelicomyces denticulatus, Neohelicosporium fluviatile, Neokalmusia aquibrunnea, Neomassariosphaeria aquimucosa, Neomyrmecridium naviculare, Neospadicoides biseptata, Ocellisimilis clavata, Ophioceras thailandense, Paragaeumannomyces aquaticus, Phialoturbella aquilunata, Pleurohelicosporium hyalinum, Pseudodactylaria denticulata, P. longidenticulata, P. uniseptata, Pseudohalonectria aurantiaca, Rhamphoriopsis aquimicrospora, Setoseptoria bambusae, Shrungabeeja fluviatilis, Sporidesmium tratense, S. versicolor, Sporoschisma atroviride, Stanjehughesia aquatica, Thysanorea amniculi, Uvarisporella aquatica and Xylolentia aseptata, with an illustrated account, discussion of their taxonomic placement and comparison with morphological similar taxa. Seven new combinations are introduced, viz. Aquabispora grandispora (≡ Boerlagiomyces grandisporus), A. websteri (≡ Boerlagiomyces websteri), Ceratosphaeria suthepensis (≡ Pseudohalonectria suthepensis), Gamsomyces aquaticus (≡ Pseudobactrodesmium aquaticum), G. malabaricus (≡ Gangliostilbe malabarica), Neocirrenalia nigrospora (≡ Cirrenalia nigrospora), and Rhamphoriopsis glauca (≡ Chloridium glaucum). Ten new geographical records are reported in China and Thailand and nine species are first reported from freshwater habitats. Reference specimens are provided for Diplocladiella scalaroides and Neocirrenalia nigrospora (≡ Cirrenalia nigrospora). Systematic placement of the previously introduced genera Actinocladium, Aqualignicola, and Diplocladiella is first elucidated based on the reference specimens and new collections. Species recollected from China and Thailand are also described and illustrated. The overall trees of freshwater Dothideomycetes and Sordariomycetes collected in this study are provided respectively and genera or family/order trees are constructed for selected taxa.

Dictyosporium splendidum sp. nov. and Helminthosporium varium sp. nov., both found on decaying leaves of unidentified plants are described and illustrated. D. splendidum is characterized by conidia composed of two or three parallel rows of cell, tightly arranged in 3-planes or complanate, with a cylindrical or irregular, hyaline mucous appendage at each apical cell. H. varium is distinguished by its blastocatenate, long obclavate, subcylindrical, oblong or navicular, 1–4-septate, spacing verrucose or verruculose, gray-brown or brown conidia.
... However, D. elegans has larger conidia (50–80 × 24–31 µm) and D. toruloides differs by unequal sizes of rows and constricted septa of the conidia (Goh et al. 1999). The Brazilian material presented conidia with smaller dimensions than the original description (27–43 × 15–30 µm), but the other characteristics conform to Zhao & Zhang (2003). This is the second world record of the species and the first for the Americas. ...
... However, the great majority of Dictyosporium species have a still limited distribution in the world. Of all the 50 species described about 37 (74%) were only recorded once or twice, these may be considered rare, such as D. brahmaswaroopii (Zhuang 2001, Mehrotra 1990) and D. taishanense (Zhao & Zhang 2003). It is, however, more likely that there are too few mycologists studying the distribution of Dictyosporium and other microfungal taxa. ...
A new species of Dictyosporium found on decaying needle-like leaves of Araucaria angustifolia in Brazil is described and illustrated. The new species is characterized by conidia being cheiroid, complanate, with 15–27 cells arranged in 4–6 rows, each with 3–6 cells, and apical cells with hyaline 3–7-celled appendages. Dictyosporium brahmaswaroopii and D. taishanense are new records for the Americas.

Dictyosporium amoenum, a new asexual fungus collected on leaves of Calophyllum brasiliense in the Brazilian semiarid Caatinga region, is described and illustrated. It is distinguished by digitate complanate brown conidia composed of four parallel compact rows of cells, each row with a globose hyaline mucous apical appendage. Conidial illustrations and a table comparing all Dictyosporium species are provided.

Oncopodium elaeagni sp. nov. is described and illustrated from the bark of Elaeagnus angustifolia collected in Hungary and from pure Culture. This species has been collected exclusively from its host, on which it was common (in 85% of the total collections). The fungus has black, granular, shining sporodochia with caespitose, straight or flexuous, hyaline conidiophores and acrogenous, hemispherical or limoniform, brown, smooth, muriform conidia bearing 2-4 short, hyaline horns. It was present permanently on an Elaeagnus tree between 2003 and 2008 where the fun-us sporulated mostly from March to July. The fungus is dispersed by stemflow rainwater; an average of 13 spores/ml was detected in rainwater samples. Some conidial forms were common in culture but rare in bark samples.

... Previous investigations (Kirk 1983, Zhao & Zhang 2005 focused on substrates such as rotting wood and fallen twigs, where these species were considered to be rare, however, they proved to be common on living trees. Since these species are frequent on economically important plants as well, especially on apple and pear-trees, their role should be studied more profoundly, concerning their effects on their hosts or other fungi. ...

A new genus, Ramoacrodictys, is erected to accommodate one species, R. malabarica, formerly placed in Acrodictys, on the basis of examination of literature and a specimen collected on Bambusa sp. in China. Ramoacrodictys is mainly characterized by erect, macronematous, multi-branched conidiophores, monoblastic conidiogenous cells and production of gangliar conidia. R. malabarica is compared with closely related species.
Five saprobic hyphomycetes with branched conidial arms, Ceratosporium fuscescens, C. gracile, C. productum, C. verrucosum and Tetraploa aristata var. sacchari are first recorded from mainland China. Descriptions and illustrations are provided for each taxon and comments on closely related genera and species are included.
