... The species within this group are generally characterized by having distinct, macronematous, mononematous, simple, single and usually unbranched erect conidiophores; conidiogenous cells are polytretic, integrated, both terminal and intercalary, determinate with conidiogenous loci at the apex and laterally below. The conidia are solitary, variously shaped (ellipsoidal, oblong, obovoid, obclavate, globose, clavate, or cuneate), unicellular or multicellular, euseptate, smooth or verruculose, subhyaline to brown or black, and dry (Xia et al. 2013;Ma et al. 2016;Qiao et al. 2019). The teleomorph stage of Spadicoides is unknown. ...
... The Index Fungorum (2021) lists around 58 taxa under the genus Spadicoides; nevertheless, many names are believed to be synonyms. To date, this large genus in terms of the number of species comprises around 42 accepted species (Xia et al. 2013;Ma et al. 2014Ma et al. , 2016 across the globe; mostly saprophytic in nature which are commonly found on a wide variety of cellulosic substrates i.e. rotten leaves, wood, branches, bark and decaying twigs of numerous trees and shrubs or on diverse dead non-woody herbaceous plant materials in both freshwater and terrestrial habitats or occasionally overgrowing carpophores of fungi (Corticiaceae, Hymenochaetaceae). The synoptic notes on relevant morphological characters of Spadicoides species have been extensively reviewed and provided by numerous researchers (Holubova-Jechova 1982;Goh and Hyde 1996;Ma et al. 2016;Xu et al. 2017). ...
Spadicoides obovata occurring on the decaying leaf litter in Berinag forest, Pithoragarh, Uttarakhand, India is described and illustrated. This rare newly recorded fungal species from India is characterized by single, straight or slightly curved, obovoid conidia with usually up to 2 septa appearing as thick dark bands, borne over the simple, erect, and proliferating conidiophores. Apart from it, the conidiogenous cells generally formed by terminal or subterminal cells, with several minute pores serve as another conspicuous feature. Notes, illustrations, descriptions based on natural substrates and comparisons with other related species based on morphological traits are provided in this paper. This represents the first report of S. obovata from India.
... Thirty-one Spadicoides species were revised, of which 21 species were accepted. Presently, 55 epithets are listed in Index Fungorum (December 2018), and most of the species are reported from terrestrial habitats (Subramanian and Vittal 1974;Kuthubutheen and Nawawi 1991a;Wong et al. 2002;Li 2010;Xia et al. 2014;.

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. Acrodictys aquatica, Cylindrotrichum aquaticum, and 9 new records, viz. Chaetomium globosum, Chaetosphaeria cubensis, Ch. myriocarpa, Cordana abramovii, Co. terrestris, Cuspidatispora xiphiago, Sporidesmiella hyalosperma, Stachybotrys chartarum,S. chlorohalonata. A comprehensive classification of the freshwater Sordariomycetes is presented based on updated literature. Phylogenetic inferences based on DNA sequence analyses of a combined LSU, SSU, RPB2 and TEF1α dataset comprising species of freshwater Sordariomycetes are provided. Detailed information including their habitats distribution, diversity, holotype, specimens collected and classification are provided.
... Castañeda (Castañeda-Ruíz 1988) was not discussed by Goh and Hyde (1996), but was included in the key to species of Spadicoides by Ma et al. (2014). Since then, 17 additional species have been described in the genus (Goh and Hyde 1998;Dulymamode et al. 1999;Zhou et al. 1999;Ho et al. 2002; Section Editor: Roland Kirschner Wong et al. 2002;Cai et al. 2004;Li 2010;Li et al. 2010;Ma et al. 2010Ma et al. , 2012Ma et al. , 2014Whitton et al. 2012;Xia et al. 2013;Heredia et al. 2015).

Hyde in conidial shape, but differs from S. bawanglingensis (conidia 98-166 × 8. 5-12 μm, 9-12euseptate) in having smaller conidia with fewer septa, and from S. bambusicola (conidia 5-7.5 μm wide) by its narrower, rostrate conidia. ...
Spadicoides lushanensis sp. nov., S. multiseptata sp. nov. and S. rostrata sp. nov. are described and illustrated from specimens collected on dead branches of unidentified plants in Lushan Mountain, China. Spadicoides lushanensis is characterized by obclavate, rostrate, pale brown, 40–65 × 4.5–5.5 μm, smooth, 6–8-euseptate conidia. Spadicoides multiseptata is easily distinguished by obclavate, smooth, 11–15-euseptate, 65–115 × 11.5–13 μm, brown to pale brown conidia with a subacute apex.

A dichotomous key to Spadicoides species is provided.
... Decaying wood in the tropical and subtropical forests of southern China supports a high level of fungal diversity, and several wood-inhabiting macrofungi and microfungi have been recently discovered there ( Gao et al. 2015;Ma et al. 2011Ma et al. , 2014Ma et al. , 2015Ma et al. , 2016Ren et al. 2012;Xia et al. 2014a, b, c; Zhang et al. 2008Zhang et al. , 2011). During our ongoing surveys of saprobic fungi associated with woody debris in Guangxi and Hainan provinces, two interesting hyphomycetes were collected on dead branches. ...
Podosporium bacilliforme is described and illustrated from specimens collected on dead branches in Guangxi Province. The fungus is characterized by black synnematal conidiomata and monotretic clavate conidiogenous cells producing solitary elongatebacilliform phragmoconidia.

... Note: Spadicoides (Hughes 1958) is distinguished by differentiated erect, straight or flexuous, unbranched conidiophores with polytretic, terminal and/ or intercalary conidiogenous cells that produce solitary, cylindrical, globose, obclavate to irregular, euseptate, pigmented conidia. Thus far, 36 species have been accepted in the genus (Xia et al. 2013). Only one species is similar to S. sylvatica, S. yunnanensis L.G. Ma & X.G. ...

Spadicoides sylvatica is distinguished by its ovate to obclavate, 3–4-septate, smooth, golden brown to brown conidia. Sporidesmiella mammillata is characterized by conidia that are solitary acrogenous, obclavate to fusiform, sub-rostrate, 4–7-distoseptate, smooth, and golden brown.
Specimens of Linkosia longirostrata, Spadicoides klotzschii, and S. sylvatica were collected on dead branches of unidentified plants and identified as new records from China.
