“…Based on the key provided by Decock et al (2003), C. eugeniae appears to represent a new species. Further collections of this complex are required to confirm the synonymy of the genera Cyphellophora with Pseudomicrodochium and Kumbhayama (Decock et al 2003, Crous et al 2007b), which were originally distinguished based on the absence of conidial pigmentation. The ITS sequence of C. eugeniae has 89 % similarity to that of Cyphellophora hylomeconis (GenBank accession EU035415).…”

The recently generated molecular phylogeny for the kingdom Fungi, on which a new classification scheme is based, still suffers from an under representation of numerous apparently asexual genera of microfungi. In an attempt to populate the Fungal Tree of Life, fresh samples of 10 obscure genera of hyphomycetes were collected. These fungi were subsequently established in culture, and subjected to DNA sequence analysis of the ITS and LSU nrRNA genes to resolve species and generic questions related to these obscure genera. Brycekendrickomyces (Herpotrichiellaceae) is introduced as a new genus similar to, but distinct from Haplographium and Lauriomyces. Chalastospora is shown to be a genus in the Pleosporales, with two new species, C. ellipsoidea and C. obclavata, to which Alternaria malorum is added as an additional taxon under its oldest epithet, C. gossypii. Cyphellophora eugeniae is newly described in Cyphellophora (Herpotrichiellaceae), and distinguished from other taxa in the genus. Dictyosporium is placed in the Pleosporales, with one new species, D. streliziae. The genus Edenia, which was recently introduced for a sterile endophytic fungus isolated in Mexico, is shown to be a hyphomycete (Pleosporales) forming a pyronellea-like synanamorph in culture. Thedgonia is shown not to represent an anamorph of Mycosphaerella, but to belong to the Helotiales. Trochophora, however, clustered basal to the Pseudocercospora complex in the Mycosphaerellaceae, as did Verrucisporota. Vonarxia, a rather forgotten genus of hyphomycetes, is shown to belong to the Herpotrichiellaceae and Xenostigmina is confirmed as synanamorph of Mycopappus, and is shown to be allied to Seifertia in the Pleosporales. Dichotomous keys are provided for species in the various genera treated. Furthermore, several families are shown to be polyphyletic within some orders, especially in the Capnodiales, Chaetothyriales and Pleosporales.

“…Cyphellophora de Vries currently encompasses dematiaceous anamorphs that form intercalary or terminal phialides bearing flaring, thin or conspicuous collarettes; in some species the collarettes are more deeply pigmented than the body of the phialide (de Vries 1962;Walz and de Hoog 1987;de Hoog et al 2000b;DeCock et al 2003). The members of this genus resemble Phialophora in features of their conidiogenous cells, but they are distinguished by their larger, fusiform to sigmoid, 1-4 septate conidia (de Vries 1962;de Hoog et al 2000b;DeCock et al 2003).…”

“…Barr form phialidic synanamorphs with flaring, dark collarettes in abundance on some media (Untereiner 1995;Untereiner et al 1995), and one of us (M.R.) obtained a phialophora-like anamorph resembling P. americana from collections identified as Capronia svrcekiana Réblová. Of the additional members of the family producing phialophora-like anamorphs or synanamorphs, only species of Cladophialophora are closely related to the P. verrucosa complex (Untereiner and Naveau 1999;de Hoog et al 2000b;DeCock et al 2003).…”

Phialophora Medlar, as defined currently, is a genus encompassing melanized, anamorphic Ascomycota that produce one-celled conidia from phialides with distinct, darkened collarettes. The type species, Phialophora verrucosa Medlar, is closely related to Phialophora americana (Nannf.) S. Hughes, the anamorph of Capronia semiimmersa (Candoussau & Sulmont) Untereiner & Naveau (Herpotrichiellaceae, Chaetothyriales). To confirm that P. americana and P. verrucosa are distinct taxa, and to examine their phylogenetic relationships to species of Capronia and other representatives of the Chaetothyriales, we sequenced portions of the b-tubulin gene and nuclear ribosomal RNA cistron (ITS and LSU rDNA). We also compared isolates of P. americana grown on a number of media. Isolates of C. semiimmersa, Capronia svrcekiana Réblová, and P. americana produced phialides bearing deep, vase-shaped collarettes and formed a strongly supported clade that did not include P. verrucosa in a phylogeny inferred from the combined b-tubulin-ITS-LSU dataset. Capronia svrcekiana was found to be conspecific with C. semiimmersa based on the comparison of cultural, micromorphological, and molecular characters. In the LSU phylogeny, three recently described species of Phialophora (Phialophora europaea de Hoog et al., Phialophora reptans de Hoog, and Phialophora sessilis de Hoog) were grouped outside of the clade containing sampled members of the Herpotrichiellaceae. While the position of these species in the Chaetothyriales remained unresolved, it was evident that P. europaea, P. reptans, and P. sessilis are not members of the P. verrucosa complex.Résumé : Selon la définition courante, le genre Phialophora Medlar comprend des Ascomycota mélanisés anamorphes qui produisent des conidies unicellulaires à partir de phialides foncées avec collerettes. L'espèce type, le Phialophora verrucosa Medlar se rapproche du Phialophora americana (Nannf.) S. Hughes, l'anamorphe du Capronia semiimmersa (Candoussau & Sulmont) Untereiner & Naveau (Herpotrichiellaceae, Chaetothyriales). Pour confirmer que le P. americana et le P. verrucosa constituent des taxons distincts et afin d'examiner leurs relations phylogénétiques avec les espèces de Capronia et autres représentants des Chaetothyriales, les auteurs ont séquencé des portions du gène de la b-tubuline et du cistron de l'ARN ribosomal nucléique (ITS et LSU rADN). Ils ont également comparé des isolats du P. americana, cultivés sur plusieurs milieux. Les isolats des C. semiimmersa, Capronia svrcekiana Réblová et P. americana produisent des phialides qui portent des collerettes profondes en forme de vase et forment un clade fortement supporté qui n'inclut pas le P. verrucosa, selon une phylogénie déduite d'une combinaison des données de l'ensemble b-tubuline-ITS-LSU. On constate que le C. svrcekiana est conspécifique avec le C. semiimmersa, sur la base des caractères culturaux, micromorphologiques et moléculaires. Dans la phylogénie LSU, trois espèces de Philophora, récemment décrites (Phialophora europaea de Hoog et al....

How fungi respond to long‐term fertilization in Chinese Mollisols as sensitive indicators of soil fertility has received limited attention. To broaden our knowledge, we used high‐throughput pyrosequencing and quantitative PCR to explore the response of soil fungal community to long‐term chemical and organic fertilization strategies. Soils were collected in a 35‐year field experiment with four treatments: no fertilizer, chemical phosphorus, and potassium fertilizer (PK), chemical phosphorus, potassium, and nitrogen fertilizer (NPK), and chemical phosphorus and potassium fertilizer plus manure (MPK). All fertilization differently changed soil properties and fungal community. The MPK application benefited soil acidification alleviation and organic matter accumulation, as well as soybean yield. Moreover, the community richness indices (Chao1 and ACE) were higher under the MPK regimes, indicating the resilience of microbial diversity and stability. With regards to fungal community composition, the phylum Ascomycota was dominant in all samples, followed by Zygomycota, Basidiomycota, Chytridiomycota, and Glomeromycota. At each taxonomic level, the community composition dramatically differed under different fertilization strategies, leading to different soil quality. The NPK application caused a loss of Leotiomycetes but an increase in Eurotiomycetes, which might reduce the plant–fungal symbioses and increase nitrogen losses and greenhouse gas emissions. According to the linear discriminant analysis (LDA) coupled with effect size (LDA score > 3.0), the NPK application significantly increased the abundances of fungal taxa with known pathogenic traits, such as order Chaetothyriales, family Chaetothyriaceae and Pleosporaceae, and genera Corynespora, Bipolaris, and Cyphellophora. In contrast, these fungi were detected at low levels under the MPK regime. Soil organic matter and pH were the two most important contributors to fungal community composition.
