“…For example, strains of C. europaea were reported from environmental samples from humid environments (i.e., bathrooms, washing machines) [60], [61], C. reptans was originally isolated from food [24], a strain of C. laciniata was isolated from a bathroom surface, and the ex-type strain of C. oxyspora was isolated from decaying leaf [19]. Cyphellophora suttonii was also detected in soil samples, although this strain has never been sequenced [12]. Other Cyphellophora that have not been involved in human infections are frequently isolated from plants or nutrient-poor substrates, and two species ( C. olivacea and C. oxyspora ) were originally classified in the Phialophora sect.…”

“…de Vries [6], encompasses dematiaceous fungi with septate, branched hyphae, intercalary, terminal or lateral phialides with indistinct or funnel-shaped collarettes, and septate, hyaline or pale brown conidia ranging in shape from oblong to fusiform or vermiform. Of the twelve members of the genus described to date, five were isolated samples of animal origin (i.e., nails and skin) [4], [6], [8], [9], [10], [11], whereas the other species occur in soil [12], on plants [13], [14], or as plant endophytes [7], [15]. Based on the analysis of small subunit nuclear ribosomal DNA (nuc18S rDNA) sequences, five species of Cyphellophora formed a strongly supported monophyletic clade that was sister to representatives of the Herpotrichiellaceae [13].…”

Novel Evolutionary Lineages Revealed in the Chaetothyriales (Fungi) Based on Multigene Phylogenetic Analyses and Comparison of ITS Secondary Structure

Cyphellophora and Phialophora (Chaetothyriales, Pezizomycota) comprise species known from skin infections of humans and animals and from a variety of environmental sources. These fungi were studied based on the comparison of cultural and morphological features and phylogenetic analyses of five nuclear loci, i.e., internal transcribed spacer rDNA operon (ITS), large and small subunit nuclear ribosomal DNA (nuc28S rDNA, nuc18S rDNA), β-tubulin, DNA replication licensing factor (mcm7) and second largest subunit of RNA polymerase II (rpb2). Phylogenetic results were supported by comparative analysis of ITS1 and ITS2 secondary structure of representatives of the Chaetothyriales and the identification of substitutions among the taxa analyzed. Base pairs with non-conserved, co-evolving nucleotides that maintain base pairing in the RNA transcript and unique evolutionary motifs in the ITS2 that characterize whole clades or individual taxa were mapped on predicted secondary structure models. Morphological characteristics, structural data and phylogenetic analyses of three datasets, i.e., ITS, ITS-β-tubulin and 28S-18S-rpb2-mcm7, define a robust clade containing eight species of Cyphellophora (including the type) and six species of Phialophora. These taxa are now accommodated in the Cyphellophoraceae, a novel evolutionary lineage within the Chaetothyriales. Cyphellophora is emended and expanded to encompass species with both septate and nonseptate conidia formed on discrete, intercalary, terminal or lateral phialides. Six new combinations in Cyphellophora are proposed and a dichotomous key to species accepted in the genus is provided. Cyphellophora eugeniae and C. hylomeconis, which grouped in the Chaetothyriaceae, represent another novel lineage and are introduced as the type species of separate genera.

“…In our study, one new Cyphellophora species, C. chlamydospora, was proposed and C. suttonii is reported for the first time from Europe, isolated from garden soil in Catalonia. The latter species was originally described as an agent of subcutaneous phaeohyphomycosis in a dog in USA (Ajello et al 1980) and was later reported from a human infection in the same country (Perfect and Schell 1996) and from soil in Brazil (Nunes et al 1999). However, the identity of the strains from human and soil have not been confirmed molecularly.…”

New and interesting chaetothyrialean fungi from Spain

In the course of taxonomic studies on saprobic microfungi from Spain, several slow-growing, dematiaceous hyphomycetes were isolated from soil, submerged plant material and river sediments. Sixteen of these strains were identified as members of the ascomycete order Chaetothyriales on the basis of morphology and DNA sequence analyses of the internal transcribed spacer region and partial large subunit ribosomal RNA gene. These included three novel species (Cladophialophora pseudocarrionii, Cyphellophora chlamydospora, and Rhinocladiella amoena) and five interesting, little-known or clinically-relevant species (Cyphellophora suttonii, Exophiala aquamarina, E. lacus, E. radicis, and Rhinocladiella similis). In addition, Exophiala oligosperma, an emerging opportunistic fungus, was found for the first time in an aquatic freshwater environment (river sediments). Cladophialophora pseudocarrionii resembles C. carrionii in the branching pattern of its conidial chains, but differs from the latter species in its inability to grow at 30 °C. Cyphellophora chlamydospora differs from other species of the genus in the absence of conidiation, producing only chlamydospores in vitro. Rhinocladiella amoena shows branched conidiophores similar to those of R. anceps, R. atrovirens, R. basitona and R. similis, but differs from them in conidial shape and size. The ex-type strain of Phialophora livistonae, included in the phylogenetic study, clustered with high statistical support with members of the genus Cyphellophora and is transferred to this genus.

These fungi were studied based on the comparison of cultural and morphological features and phylogenetic analyses of five nuclear loci, i.e., internal transcribed spacer rDNA operon (ITS), large and small subunit nuclear ribosomal DNA (nuc28S rDNA, nuc18S rDNA), b-tubulin, DNA replication licensing factor (mcm7) and second largest subunit of RNA polymerase II (rpb2). Phylogenetic results were supported by comparative analysis of ITS1 and ITS2 secondary structure of representatives of the Chaetothyriales and the identification of substitutions among the taxa analyzed. Base pairs with non-conserved, co-evolving nucleotides that maintain base pairing in the RNA transcript and unique evolutionary motifs in the ITS2 that characterize whole clades or individual taxa were mapped on predicted secondary structure models.

Occorrence of Pseudomicrodochium suttonii in Brazil

Abstract: Pseudomicrodochium suttonii was isolated from the soil of Derby Square, a leisure area in Recife city, Pernambuco, Brazil. For the isolation, suspensions were made in distilled sterile water. According to the literature, this is probably the first occurrence reported in South America.
