  journal={Mycological Progress},
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.

Filobasidiella lutea: parasitism of Hypochnicium vellereum

The purpose of this paper is to confirm the connection between F lutea and its host, document variability in some morphological features, and extend the geographic range.

Filobasidiella arachnophila sp. nov.

A new species of Filobasidiella Kwon-Chung was isolated from a dead spider and appears to be nonpathogenic and differs from previously described species in being homothallic and in lacking a yeast-like phase of growth.

On the taxonomy of the entomogenous fungus Filobasidiella arachnophila

The carbohydrate profile of two strains revealed basidiomycetous affinities, but the vast majority of the mycelial cells are monokaryotic, demonstrating that F. arachnophila is not a typical basidiology, and therefore the accommodation in Filobasidiella is maintained.

Morphogenesis of Filobasidiella neoformans, the sexual state of Cryptococcus neoformans.

It is shown that a dikaryotic mycelium with clamp connections is formed after conjugation of two yeast cells of opposi...

Haustoria of the Mycoparasitic Heterobasidiomycete Christiansenia pallida

The cellular interaction of Christiansenia pallida and Phanerochaete cremea was restudied by transmission electron microscopy and several micropores are produced between the haustorial filament and the host cell.


The status of the generic name Syzygospora is reviewed and the holomorph name is applied to a group of Basidiomycetes. Nine species are accepted in the genus. Three are proposed as new species (S.

Direct cytoplasm-cytoplasm connection: an unusual host-parasite interaction of the tremelloid mycoparasiteTetragoniomyces uliginosus

Among basidiomycetes, direct connection between the parasite and host protoplasts represents a hitherto unknown type of parasitic interaction.

The life-history of Christiansenia pallida, a dimorphic, mycoparasitic heterobasidiomycete

Higher taxa of basidiomycetes: an 18S rRNA gene perspective

In order to identify monophyletic groups and evaluate competing class level systems of classification, the 18S rRNA gene from nine basidiomycetes is sequenced.
