Rodents consume and subsequently disperse fungi through their feces on every continent except Antarctica. This study examines the fungal taxa consumed by the Hastings River mouse (Pseudomys oralis), an endangered Australian endemic rodent from the family Muridae.

Nivicolous Trichiales from the austral Andes: unexpected diversity including two new species Mycologia (IF 2.149) Pub Date : 2020-07-10 Anna Ronikier; Iván García-Cunchillos; Paulina Janik; Carlos Lado
Nivicolous myxomycetes are a group of amoebozoan protists dependent on long-lasting snow cover worldwide. Recent fine-scale analysis of species diversity from the austral Andes revealed high intraspecific variability of most taxa, suggesting independent evolutionary processes and significant differences in species compositions between the Northern (NH) and Southern (SH) Hemispheres. The present study

Seven new species of Graphilbum from conifers in Norway, Poland, and Russia. Mycologia (IF 2.149) Pub Date : 2020-07-07 Robert Jankowiak,Halvor Solheim,Piotr Bilański,Seonju Marincowitz,Michael J Wingfield
ABSTRACT During surveys of insect-associated mycobiomes in Norway, Poland, and Russia, isolates with affinity to Graphilbum (Ophiostomatales, Ascomycota) were recovered. In this study, eight known Graphilbum species as well as the newly collected isolates were compared based on morphology and DNA sequence data for four gene regions. The results revealed seven new species, described here as G. acuminatum

Four mycangium types and four genera of ambrosia fungi suggest a complex history of fungus farming in the ambrosia beetle tribe Xyloterini. Mycologia (IF 2.149) Pub Date : 2020-06-18 Chase G Mayers,Thomas C Harrington,Douglas L Mcnew,Richard A Roeper,Peter H W Biedermann,Hayato Masuya,Craig C Bateman
ABSTRACT Ambrosia beetles farm fungal cultivars (ambrosia fungi) and carry propagules of the fungal mutualists in storage organs called mycangia, which occur in various body parts and vary greatly in size and complexity. The evolution of ambrosia fungi is closely tied to the evolution and development of the mycangia that carry them. The understudied ambrosia beetle tribe Xyloterini included lineages

Ophiocordyceps desmidiospora, a basal lineage within the "Zombie-Ant Fungi" clade. Mycologia (IF 2.149) Pub Date : 2020-06-02 Stephen J Saltamachia,João P M Araújo
ABSTRACT The genus Ophiocordyceps contains the most diverse assemblage of fungi that attack ants worldwide and are remarkably well adapted to the specific ecologies of their hosts. Desmidiospora myrmecophila Thaxt. is closely related to other ant-pathogenic species within Ophiocordyceps, possibly specific to queens, but the sheer infrequency of encounters and previously unsuccessful attempts to culture

Taxonomic revision of species of Kuehneola and Phragmidium on Rosa, including two new species from China. Mycologia (IF 2.149) Pub Date : 2020-05-29 Yun Liu,Ying-Mei Liang,Yoshitaka Ono
Kuehneola japonica and K. warburgiana are the only species of genus Kuehneola that parasitize plants belonging to genus Rosa (Rosaceae). Systematic revision of the genus Phragmidium and related genera by molecular phylogenetic analyses using nuc rDNA internal transcribed spacer (5.8S-ITS2 = ITS2) and nuc rDNA 28S (28S) sequences indicated that K. japonica and K. warburgiana belong to a group of Phragmidium

First description of the sexual stage of Venturia effusa, causal agent of pecan scab. Mycologia (IF 2.149) Pub Date : 2020-05-29 Nikki D Charlton,Mihwa Yi,Clive H Bock,Minling Zhang,Carolyn A Young
ABSTRACT Pecan scab, caused by Venturia effusa, is the most prevalent disease of pecan in the southeastern United States. Recent characterization of the mating type (MAT) distribution of V. effusa revealed that the MAT idiomorphs are in equilibrium at various spatial scales, indicative of regular sexual recombination. However, the occurrence of the sexual stage of V. effusa has never been observed
