Fungal diversity notes 111–252—taxonomic and phylogenetic contributions to fungal taxa

Taxonomic names are key links between various databases that store information on different organisms. Several global fungal nomenclural and taxonomic databases (notably Index Fungorum, Species Fungorum and MycoBank) can be sourced to find taxonomic details about fungi, while DNA sequence data can be sourced from NCBI, EBI and UNITE databases. Although the sequence data may be linked to a name, the quality of the metadata is variable and generally there is no corresponding link to images, descriptions or herbarium material. There is generally no way to establish the accuracy of the names in these genomic databases, other than whether the submission is from a reputable source. To tackle this problem, a new database (FacesofFungi), accessible at www.facesoffungi.org
 (FoF) has been established. This fungal database allows deposition of taxonomic data, phenotypic details and other useful data, which will enhance our current taxonomic understanding and ultimately enable mycologists to gain better and updated insights into the current fungal classification system. In addition, the database will also allow access to comprehensive metadata including descriptions of voucher and type specimens. This database is user-friendly, providing links and easy access between taxonomic ranks, with the classification system based primarily on molecular data (from the literature and via updated web-based phylogenetic trees), and to a lesser extent on morphological data when molecular data are unavailable. In FoF species are not only linked to the closest phylogenetic representatives, but also relevant data is provided, wherever available, on various applied aspects, such as ecological, industrial, quarantine and chemical uses. The data include the three main fungal groups (Ascomycota, Basidiomycota, Basal fungi) and fungus-like organisms. The FoF webpage is an output funded by the Mushroom Research Foundation which is an NGO with seven directors with mycological expertise. The webpage has 76 curators, and with the help of these specialists, FoF will provide an updated natural classification of the fungi, with illustrated accounts of species linked to molecular data. The present paper introduces the FoF database to the scientific community and briefly reviews some of the problems associated with classification and identification of the main fungal groups. The structure and use of the database is then explained. We would like to invite all mycologists to contribute to these web pages.

The Faces of Fungi database: fungal names linked with morphology, phylogeny and human impacts

Sooty moulds are a remarkable, but poorly understood group of fungi. They coat fruits and leaves superficially with black mycelia, which reduces photosynthesis rates of host plants. Few researchers have, however, tried to quantify their economic importance. Sooty moulds have been well-studied at the morphological level, but they are poorly represented in a natural classification based on phylogeny. Representatives are presently known in Antennulariellaceae, Capnodiaceae, Chaetothyriaceae, Coccodiniaceae, Euantennariaceae, Metacapnodiaceae and Trichomeriaceae and several miscellaneous genera. However, molecular data is available for only five families. Most sooty mould colonies comprise numerous species and thus it is hard to confirm relationships between genera or sexual and asexual states. Future studies need to obtain single spore isolates of species to test their phylogenetic affinities and linkages between morphs. Next generation sequencing has shown sooty mould colonies to contain many more fungal species than expected, but it is not clear which species are dominant or active in the communities. They are more common in tropical, subtropical and warm temperate regions and thus their prevalence in temperate regions is likely to increase with global warming. Sooty moulds are rarely parasitized by fungicolous taxa and these may have biocontrol potential. They apparently grow in extreme environments and may be xerophilic. This needs testing as xerophilic taxa may be of interest for industrial applications. Sooty moulds grow on sugars and appear to out-compete typical “weed” fungi and bacteria. They may produce antibiotics for this purpose and their biochemical potential for obtaining novel bioactive compounds for medical application is underexplored.

Colletotrichum is the causal agent of anthracnose and other diseases on leaves, stems and fruits of numerous plant species, including several important crops. Accurate species identification is critical to understand the epidemiology and to develop effective control of these diseases. Morphologically-based identification of Colletotrichum species has always been problematic, because there are few reliable characters and many of these characters are plastic, dependent upon methods and experimental conditions. Rapid progress in molecular phylogenetic methods is now making it possible to recognise stable and well-resolved clades within Colletotrichum. How these should be reflected in a classification system remains to be resolved. An important step in providing a stable taxonomy for the genus is to epitypify existing names, and in so doing link them to genetically defined clades. We recommend a polyphasic approach to the recognition and identification of species within Colletotrichum, matching genetic distinctness with informative morphological and biological characters. This paper reviews various approaches in the study of Colletotrichum complexes including morphology, pathogenicity, physiology, phylogenetics and secondary metabolite production. A backbone phylogenetic tree using ITS sequence data from 42 ex-type specimens has been generated. Phylogenetic analysis using ITS sequence data is a useful tool to give a preliminarily identification for Colletotrichum species or place them in species complexes. However, caution must be taken here as the majority of the ITS sequences deposited in GenBank are wrongly named. Multi-gene phylogenetic data provides much better understanding of the relationships within Colletotrichum and should be employed where possible. We propose that an ideal approach for Colletotrichum systematics should be based on a multi-gene phylogeny, with comparison made with type specimens, and a well-defined phylogenetic lineage should be in conjunction with recognisable polyphasic characters, such as morphology, physiology, pathogenicity, cultural characteristics and secondary metabolites. Finally a set of protocols and methodologies is provided as a guideline for future studies, epitypification and the description of new species.

A polyphasic approach for studying Colletotrichum

Fungal diversity notes 1–110: taxonomic and phylogenetic contributions to fungal species

Pestalotiopsis is a taxonomically confused, pathogenic and chemically creative genus requiring a critical re-examination using a multi-gene phylogeny based on ex-type and ex-epitype cultures. In this study 40 isolates of Pestalotiopsis, comprised of 28 strains collected from living and dead plant material of various host plants from China were studied by means of morphology and analysis of ITS, β–tubulin and tef1 gene sequence data. Based on molecular and morphological data we describe 14 new species (Pestalotiopsis asiatica, P. chinensis, P. chrysea, P. clavata, P. diversiseta, P. ellipsospora, P. inflexa, P. intermedia, P. linearis, P. rosea, P. saprophyta, P. umberspora, P. unicolor and P. verruculosa) and three species are epitypified (P. adusta, P. clavispora and P. foedans). Of the 10 gene regions (ACT, β-tubulin, CAL, GPDH, GS, ITS, LSU, RPB 1, SSU and tef1) utilized to resolve cryptic Pestalotiopsis species, ITS, β–tubulin and tef1 proved to be the better markers. The other gene regions were less useful due to poor success in PCR amplification and/or in their ability to resolve species boundaries. As a single gene tef1 met the requirements for an ideal candidate and functions well for species delimitation due to its better species resolution and PCR success. Although β-tubulin showed fairly good differences among species, a combination of ITS, β-tubulin and tef1 gene data gave the best resolution as compared to single gene analysis. This work provides a backbone tree for 22 ex-type/epitypified species of Pestalotiopsis and can be used in future studies of the genus.

The phylogenetic relationships of Chalara and allied taxa are studied based on ribosomal DAN sequences. Partial 28S rDNA and 18S rDNA regions from 26 strains were sequenced in this study. These and related sequences from GenBank were analyzed using parsimony and Bayesian analyses. Most of the Chalara species clustered in a strongly supported monophyletic lineage representing Helotiales. However, a few Chalara species appeared closely related to Xylariales. The phylogenetic significance of morphological characters observed in Chalara species are evaluated based on our sequence analyses. Conidial septation, conidial width and conidiophore pigmentation are thought to be indicative in understanding their evolutionary relationships. Sterile setae, which traditionally have been used to delimitate Chaetochalara from Chalara, are phylogenetically insignificant.

We assessed the phylogenetic relationships of 19 isolates belonging to Acrophialophora and Taifanglania based on internal transcribed spacer (ITS), nuclear 18S subunit (nuc 18S) rDNA and β-tubulin sequences. Phylogenetic data showed that Acrophialophora and Taifanglania comprise a monophyletic clade, but did not support the distinction of two genera. Being the older and more frequently used name, Acrophialophora is adopted as the generic name and Taifanglania is treated as a synonym. The generic concept of Acrophialophora is emended to include the morphological characters formerly used to distinguish Taifanglania. Three new thermotolerant species isolated from soil samples in China are described and illustrated, (i) A. ellipsoidea, with solitary phialides tapering into thin necks and long chains of ellipsoidal to fusiform conidia, (ii) A. angustiphialis with single phialides terminal or lateral on hyphae, and long chains of ellipsoidal or fusiform conidia and, (iii) A. acuticonidiata with single phialides...

Polyphasic characterisation of Chaetomium species from soil and compost revealed high number of undescribed species

Myceliophthora guttulata sp. nov. is described and illustrated based on strains isolated from soil in China. This species is thermophilic with optimal growth temperature of 40–45 °C, and minimum growth temperature of 25 °C. Morphologically, this species is characterized by smooth, guttulate, pyriform to obovoid blastoconidia born directly on the side of hyphae, on long or short pedicels or in groups of 1–4 on ampulliform swellings. Phylogenetic analysis based on multi-locus alignment of internal transcribed spacer (ITS), elongation factor 1-alpha (EF1-α) and RNA polymerase II subunit (RPB2) regions showed that M. guttulata clustered within the genus Myceliophthora, and is closely related to four thermophilic species, i.e. M. fergusii, M. thermophila, M. heterothallic, and M. hinnulea.
