Haustorial branches are described and illustrated in Filobasidiella depauperata (Basidiomycota: Tremellales). Their close association with hyphae of Verticillium lecanii indicates that F. depauperata is mycoparasitic and not, as previously thought, entomopathogenic. A key to the taxa of the genus is included. 

Cryptococcus depauperatus, a close relative of the human-pathogen C. neoformans, associated with coffee leaf rust (Hemileia vastatrix) in Cameroon.

Morphological and molecular evidence was generated supporting the identification of the fungus on rust pustules as C. depauperatus, the first record of C.depauperatu from Africa and of its association with coffee leaf rust.

The biology of the Cryptococcus neoformans species complex.

Application of recent insights into the life cycle of C. neoformans and its different ways of engaging in sexual reproduction under laboratory conditions has just begun to affect research on the ecology and epidemiology of this human pathogenic fungus.

Systematics of the Genus Cryptococcus and Its Type Species C. neoformans

This revision implies that if one uses a modern phylogenetic genus concept, only those anamorphic species that belong to the Filobasidiella clade should be classified as Cryptococcus species, e.g., C. neoformans, C. gattii, and C. amylolentus.

Fungal evolution: major ecological adaptations and evolutionary transitions

A new scenario is proposed for fungal terrestralization, which considers icy environments as a transitory niche between water and emerged land and the importance of genome‐enabled inferences to envision plausible narratives and scenarios for important transitions is highlighted.

Networks Depicting the Fine-Scale Co-Occurrences of Fungi in Soil Horizons

This study analyzed how taxonomically and functionally diverse fungi showed correlated fine-scale distributions in soil and led to the working hypothesis that mycorrhizal, endophytic, saprotrophic, and pathogenic fungi could form compartmentalized networks of facilitative, antagonistic, and/or competitive interactions in belowground ecosystems.

Mechanisms of Homothallism in Fungi and Transitions between Heterothallism and Homothallism

The structural analyses of MAT sequences from homothallic and heterothallic Cochliobolus species support the hypothesis that heterothallism is the ancestral state in this genus, and there is evidence supporting both hypotheses.

Obligate sexual reproduction of a homothallic fungus closely related to the Cryptococcus pathogenic species complex

These findings support C. depauperatus as an obligately sexual, homothallic fungal species and provide additional insight into the repeated transitions between modes of sexual reproduction that have occurred throughout the fungal kingdom.

Yeasts

Fission yeasts grow lengthwise and divide by forming a cell septum that constricts mother cells into two equal-sized daughters, and sporulation The production of haploid spores when sexually reproductive yeasts conjugate and undergo meiosis.
