“…(2014) proposed Cephalotrichum heliciforme as nomen novum for Trichurus spiralis Hasselbr. to avoid nomenclatural conflict with the recently described species Cephalotrichum spirale by Jiang et al. (2011) , which was characterised by the spiral pattern of roughness on the conidial surface.…”

“…Doratomyces ( Sturm 1829 ), typified by D. neesii , currently includes 22 species, five of them of uncertain application and shares morphological characteristics with Cephalotrichum . Since the application of Cephalotrichum was unclear to them, Morton & Smith (1963) considered the former as a possible synonym of Doratomyces whereas other authors, following the lectotypification of the genus by Hughes (1958) , considered Cephalotrichum as the correct name for this genus ( Carmichael et al., 1980 , Arx, 1981 , Abbott, 2000 , Jiang et al., 2011 , Seifert et al., 2011 , Beer et al., 2013 ). Cephalotrichum was sanctioned by Fries (1832) , and it is currently included in the proposed List of Protected Fungal Generic Names ( Kirk et al.…”

The taxonomy of the synnematous genera Cephalotrichum, Doratomyces and Trichurus, and other related genera Gamsia, Wardomyces and Wardomycopsis, has been controversial and relies mainly on morphological criteria. These are microascaceous saprobic fungi mostly found in air and soil and with a worldwide distribution. In order to clarify their taxonomy and to delineate generic boundaries within the Microascaceae, we studied 57 isolates that include clinical, environmental and all the available ex-type strains of a large set of species by means of morphological, physiological and molecular phylogenetic analyses using DNA sequence data of four loci (the ITS region, and fragments of rDNA LSU, translation elongation factor 1α and β-tubulin). The results demonstrate that Cephalotrichum, Doratomyces and Trichurus are congeneric and the genus Cephalotrichum is accepted here with Echinobotryum as a further synonym. The genera Acaulium and Fairmania, typified by A. albonigrescens and F. singularis, respectively, are distinct from Microascus and Scopulariopsis, Gamsia is distinct from Wardomyces, and Wardomycopsis is confirmed as a separate genus in the Microascaceae. Two new species of Cephalotrichum are described as C. brevistipitatum and C. hinnuleum. Nine new combinations are proposed, i.e. Acaulium acremonium, A. caviariforme, Cephalotrichum asperulum, C. columnare, C. cylindricum, C. dendrocephalum, C. gorgonifer, Gamsia columbina and Wardomyces giganteus. A neotype is designed for C. stemonitis. Lectotypes and epitypes are designated for A. acremonium, A. albonigrescens, C. gorgonifer, C. nanum and W. anomalus. Cephalotrichum cylindricum, C. microsporum, F. singularis and Gamsia columbina are also epitypified with new specimens. Descriptions of the phenotypic features and dichotomous keys for identification are provided for accepted species in the different genera.

“…C. stemonitis was identified in coyote and rat dung, the indoor air of a honeybee (Apis mellifera) overwintering facility, the cones of white spruce, sandy soil, decayed wood of white spruce, soil of elm woods, and agricultural soil [24]. Recently, there are 14 new species of Cephalotrichum were explained based on the isolation from soils in China [25]. Although Cephalotrichum species are not considered as human pathogens and also not known to produce mycotoxins, but C. gorgonifer was collected from human clinical samples and can survive at human body temperatures [13].…”

A New Species of Thelonectria and a New Record of Cephalotrichum hinnuleum from Gunwi and Ulleungdo in Korea

Three fungal strains belonging to the class Sordariomycetes were isolated from soils collected from Gyeongsangbuk-do in Korea. They were identified as Cephalotrichum hinnuleum (UD CT 1-3-3 and KNU-19GWF1) and Thelonectria chlamydospora sp. nov. (UD ST 1-2-1). T. chlamydospora sp. nov. was morphologically identical to T. truncata, but its specific macroconidial dimensions, lower number of septations, and chlamydospore diameter render it distinct from the strains of the genus Thelonectria. The strains UD CT 1-3-3 and KNU-19GWF1 were developed flat, velvety to felty, and golden gray to brown-gray after 14 days of incubation at 25 C on PDA. These strains were produced polyblastic conidiogenous cells and conidia were pale brown to brown, smooth, thin-walled, subglobose to ellipsoidal, arranged in chains, and the diameters of 6.7-9.0 Â 3.7-5.1 lm. The strains were also confirmed by using the multi-locus genes using internal transcribed spacer (ITS) regions, partial large subunit (LSU), translation elongation factor 1a (TEF1-a), b-tubulin (TUB2), and actin (ACT) genes. This is the discovery of T. chlamydospora sp. nov. and Cephalotrichum hinnuleum, a new record from Korea.

“…Recently, 14 new Cephalotrichum species were described based on isolates from soil from China ( Jiang and Zhang, 2008 , Jiang et al., 2011 ). The status of those species, only known from their holotypes, could not be thoroughly evaluated by Sandoval-Denis et al.…”

“…Their list of uncertain or excluded species included 43 Cephalotrichum spp., and seven Doratomyces spp. These included 14 new Cephalotrichum species described recently from China, mostly based on morphology characters alone ( Jiang and Zhang, 2008 , Jiang et al., 2011 ). We were fortunate to obtain herbarium material of these latter species for study, allowing us to evaluate them in the broader context of the Cephalotrichum taxonomy established by Sandoval-Denis et al.…”

A recent taxonomic revision of Microascaceae with an emphasis on synnematous fungi enabled re-identification of previously isolated indoor strains of Cephalotrichum. All available Cephalotrichum strains from the culture collection of the Westerdijk Institute were studied, 20 originating from the built environment. Phylogenetic relationships were inferred from DNA sequence data from the internal transcribed spacer 1 and 2 and intervening 5.8S nrDNA (ITS), and parts of β-tubulin (tub2) and translation elongation factor 1-α (tef1) genes. Additionally, herbarium material of 14 Cephalotrichum species described from soil in China was studied, and the taxonomy of C. album, not considered in recent revisions, was reevaluated. Sixteen phylogenetic species in Cephalotrichum are distinguished, five described as new species: C. domesticum, C. lignatile, C. telluricum, C. tenuissimum and C. transvaalense. Five Cephalotrichum species occur in the built environment: C. domesticum, C. gorgonifer (formerly known as Trichurus spiralis), C. microsporum, C. purpureofuscum, and C. verrucisporum. Based on the number of isolates, C. gorgonifer (nine strains) is the most common indoor species. The study of the Chinese herbarium material resulted in the acceptance of three additional Cephalotrichum species: C. casteneum, C. ellipsoideum, and C. spirale. Four species are considered nomena dubia (C. cylindrosporum, C. macrosporum, C. ovoideum, and C. robustum), five are placed in synonymy with other Cephalotrichum species (C. acutisporum, C. inflatum, C. longicollum, C. oblongum, C. terricola) and one species, C. verrucipes, is probably a synonym of Penicillium clavigerum. Cephalotrichum columnare, former Doratomyces columnaris, is transferred to Kernia. Cephalotrichum album, formerly known as Doratomyces putredinis, is transferred to Acaulium and redescribed.
