“…Then great effort has been made to classify, identify, and accurately grouping different species of Chaetomium , based on DNA sequencing [18]. Chaetomium and other members of the Chaetomiaceae were studied with 18S and 28S rDNA sequences individually [33, 34] (or in combination with tef and rbp2 genes [35] These studies have supported the monophyly of the Chaetomiaceae, occupying a sister relationship to other families of Sordariales, especially Lasiosphaeriacea. Some Chaetomium species are reported to be associated with Acremonium, Botryotrichum, Humicola, Paecilomyces , and Scopulariopsis [36].…”

Species of Chaetomiaceae family are ubiquitous filamentous fungi, that responsible for a wide range of opportunistic human infections. To date, it encompasses more than 300 species have been described in genus Chaetomium. It have been globally reported as being are capable of colonizing various substrates. Due to the lack of genetic studies on the species belonging to this genus in Sudan, This work aimed to investigate the environmental fungal occurrence within the family Chaetomiaceae by using morphological characters and molecular sequencing. A total of 260 environmental samples from soil, animal dung and water were collected from six different states in Sudan in two ecozones: .desert or semis desert ecozones (Dongola in Northern sudan, El-Obeid in western sudan ); a low rainfall woodland savanna ecozone (Gazira, El Geteina and Khartoum from central Sudan and AlQadarif in eastern Sudan). During a study of environmental fungi in Sudan , 119 isolates were identified as members of Chaetomiaceae after the ITS sequencing combined with an examination of the macro- and micromorphology. Out of 63 Chaetomium strains obtained from soil, animal dung and water samples , 25 were obtained from soil , 22 from animal dung and 16 from water. 56 additional strains isolated from other genus within the Chaetomiaceae family, such as (Amesia, Collariella, Ovatospora ,Subramaniula and Thielavia) were recorded for the first time in Sudan. In conclusion: Sequence-based identification of fungal isolates is often considered to be the most reliable and accurate identification method. Key words: Chaetomiaceae, Indoor species, Morphological diversity, Phylogeny.

“…Molecular phylogenetic studies of Chaetomium have been conducted by several authors (Lee and Hanlin 1999;Untereiner et al 2001;Greif et al 2009;Asgari and Zare 2011). However, because of the limited sampling in previous studies, the phylogenetic relationships among the majority of Chaetomium species remain unclear, and the current circumscriptions of these Chaetomium species lack phylogenetic evaluation.…”

Historically, the Chaetomium indicum group contained six species with similar ascus and ascospore morphology. Large morphological variation in their branched ascomatal hairs often resulted in ambiguous species delimitation. In this study, morphological characters and the maximum growth temperature (MGT) are evaluated in light of phylogenetic relationships. Multigene phylogenetic analyses with ribosomal internal transcribed spacer (ITS), partial ribosomal large subunits (28S rDNA), β-tubulin, the translation elongation factor 1α (TEF1-α), and the largest subunit of RNA polymerase ІІ (RPB1) recognize eight well-supported lineages within the monophyletic C. indicum group. The eight lineages correspond to five known species and three new species described in this paper (i.e., C. pratense, C. subfunicola, and C. ramosissimum). Chaetomium dolichotrichum is resurrected, as it appears to be a distinct species from C. funicola. Chaetomium cancroideum, though phylogenetically consistent with C. funicola, is retained as separate because of its distinct morphology. Both C. funicola and C.indicum are epitypified to stabilize the taxonomy.

Little is known about opportunistic fungi causing skin lesions in tropical countries such as Panama. We report an 83-year-old man from Chiriquí, Western Panama, with crusted skin lesions covering tumorous masses resembling Bowen's disease of the skin on the dorsum of his right hand. Fungal cultures were obtained on different nutrient media from disinfected superficial skin scrapings and fragments taken from a deep skin biopsy. Deep skin biopsy showed the presence of globose, dark fungal cells in the upper and lower dermis, sometimes in abscesses or giant cells, indicating chromoblastomycosis. All fungal fragments plated on nutrient media yielded colonies of Chaetomium funicola which was identified based on morphological observations and molecular sequence data of large ribosomal subunit rDNA. Treatment with fluconazole was ineffective. Further treatments could not be applied because of the patient's advanced age, low compliance, and limited resources in a rural, tropical environment. For the first time, C. funicola is confirmed as an opportunistic fungus causing superficial and deep cutaneous lesions. Up to now, the only known clinical record of this species is a tentative identification as an agent of deep mycosis.
