The 17 species currently included in this genus are delimited by conidial shape, size, number of septa, and pigmentation (Castañeda et al. 2001, Ma et al. 2011).

A new genus and species, Arthrotaeniolella aquatica, and a new species, Pseudospiropes piatanensis, collected on submerged decaying plant materials in the Brazilian semiarid region, are described and illustrated. Arthrotaeniolella aquatica is characterized by distinct, sinuate, slender, branched, hyaline or subhyaline to pale dirty brown conidiophores that produce cylindrical to sub-oblong, unicellular to euseptate, dark brown conidia formed by thallic-arthric disarticulation of the branches. Pseudospiropes piatanensis is distinguished by a polyblastic conidiogenous cell that produces fusiform to lunate, 10–15-distoseptate, pale brown conidia.
... Its decomposition plays an important role in the nutrient cycling, and provides a rich habitat for saprophytic fungi. However, the conidial fungi associated with dead branches are poorly known in China, and presently only a few studies have been devoted to them (e.g., Wu & Zhuang 2005; Zhang et al. 2009, 2012; Ma et al. 2011; Ren et al. 2012; Zhao et al. 2012; Xia et al. 2014). ...
Two new anamorphic fungi, Sporidesmiella nanlingensis sp. nov. and S. bawanglingensis sp. nov. are described and illustrated from specimens collected on dead branches in southern China. Sporidesmiella nanlingensis is characterized by terminal, annellidic conidiogenous cells with solitary, clavate to cuneiform, smooth, 4-distoseptate, 15–20 × 6–6.5 μm conidia with a rounded papilla at the apex. S. bawanglingensis differs from other described Sporidesmiella species in producing comparatively smaller, obclavate to fusiform, 5-distoseptate and smooth conidia. The novelties are morphologically compared with similar taxa.
... Pseudospiropes xishuangbannicus is most similar to P. linderae Jian Ma et al. in conidial shape. However, the conidia of P. linderae are smaller and have fewer septa (14-17 × 5.5-6.5 µm, 3-distoseptate; Ma et al. 2011b). Markovsk., Mycotaxon 87: 181, 2003. ...

This is a continuity of a series of taxonomic papers where materials are examined, described and novel combinations are proposed where necessary to improve our traditional species concepts and provide updates on their classification. In addition to extensive morphological descriptions and appropriate asexual and sexual connections, DNA sequence data are also analysed from concatenated datasets (rDNA, TEF-α, RBP2 and β-Tubulin) to infer phylogenetic relationships and substantiate systematic position of taxa within appropriate ranks. Wherever new species or combinations are being proposed, we apply an integrative approach (morphological and molecular data as well as ecological features wherever applicable). Notes on 125 fungal taxa are compiled in this paper, including eight new genera, 101 new species, two new combinations, one neotype, four reference specimens, new host or distribution records for eight species and one alternative morphs. The new genera introduced in this paper are Alloarthopyrenia, Arundellina, Camarosporioides, Neomassaria, Neomassarina, Neotruncatella, Paracapsulospora and Pseudophaeosphaeria.

In a survey of saprobic conidial fungi from southern China, a new species, Blastophragma beilschmiediae, is proposed. It is characterized by simple mononematous conidiophores with integrated apical polyblastic conidiogenous cells and solitary, acrogenous, 9–13-distoseptate conidia produced on sympodially proliferating conidiogenous cells. Beltraniomyces lignicola, Diplococcium dendrocalami, and Teratosperma cornigerum are newly recorded from China. Notes, illustrations and descriptions based on natural substrates are presented for all species.
We are studying the freshwater lignicolous fungi along a north-south latitudinal gradient in Asia. In this paper, fresh collections of Minimelanolocus from submerged wood in streams in Yunnan Province, China are characterised based on morphology and molecular phylogeny based on three rDNA regions: 18S (SSU), ITS1-5.8S-ITS2 (ITS) and 28S nuclear rDNA (LSU). The phylogenetic analysis of combined LSU and SSU sequence data and a separate analysis of ITS placed the isolates within the family Herpotrichiellaceae, order Chaetothyriales. An updated phylogenetic backbone tree for Chaetothyriales is provided with available ex-type and additional isolates. One of the isolates collected was identified as Minimelanolocus obscurus based on morphology and molecular data. Minimelanolocus aquaticus, M. asiaticus, M. curvatus and M. melanicus are described as new species considering the interspecific ITS variability and morphology. The phylogenetic placement of Minimelanolocus in Chaetothyriales is novel and provides new sequence data for the genus as a distinct lineage in Chaetothyriales. The conidial characters of all the known species in the genus are summarized. Descriptions and illustrations are provided for the five species of Minimelanolocus with notes on their taxonomy and phylogeny.
Two microfungi from a forest in Portugal are described and illustrated. The new
species Minimelanolocus manifestus is distinguished by polyblastic, integrated, sympodial
conidiogenous cells, and solitary, cymbiform, (2–)3-septate, smooth conidia with pale brown
middle cells and subhyaline end cells. A new combination Vermiculariopsiella pediculata is
proposed for Gyrothrix pediculata.
