Inclusion of database outgroups reduces false positives in fungal metabarcoding taxonomic assignments Mycologia (IF 2.8) Pub Date : 2023-05-17 Clayton Rawson, Geoffrey Zahn
ABSTRACT Metabarcoding studies of fungal communities rely on curated databases for assigning taxonomy. Any host or other nonfungal environmental sequences that are amplified during polymerase chain reaction (PCR) are inherently assigned taxonomy by these same databases, possibly leading to ambiguous nonfungal amplicons being assigned to fungal taxa. Here, we investigated the effects of including nonfungal

Using fimbrin to quantify the endocytic subapical collar during polarized growth in three filamentous fungi Mycologia (IF 2.8) Pub Date : 2023-05-17 Joseph G. Vasselli, Ellen Kainer, Brian D. Shaw
ABSTRACT Filamentous fungi produce specialized cells called hyphae. These cells grow by polarized extension at their apex, which is maintained by the balance of endocytosis and exocytosis at the apex. Although endocytosis has been well characterized in other organisms, the details of endocytosis and its role in maintaining polarity during hyphal growth in filamentous fungi is comparatively sparsely

Comparative genomics and phylogenomic investigation of the class Geoglossomycetes provide insights into ecological specialization and the systematics of Pezizomycotina Mycologia (IF 2.8) Pub Date : 2023-05-11 Tina Melie, Stacy Pirro, Andrew N. Miller, Stacey D. Smith, Kyle S. Schutz, C. Alisha Quandt
ABSTRACT Despite their global presence and ubiquity, members of the class Geoglossomycetes (Pezizomycotina, Ascomycota) are understudied systematically and ecologically. These fungi have long been presumed saprobic due to their occurrence in or near leaf litter and soils. Additionally, they lack an apparent association with other organisms, reinforcing this perception. However, observations of sporocarps

Systemic infection of Bryoria (Lecanoromycetes, Ascomycota) by Athelia (Agaricomycetes, Basidiomycota) in western North America Mycologia (IF 2.8) Pub Date : 2023-04-27 Spencer Goyette, Viacheslav Spirin, Toby Spribille
ABSTRACT Bryoria (Parmeliaceae, Ascomycota) is one of the dominant genera of hair lichens in western North America and is characteristic of high-elevation conifer forest ecosystems. In areas where Bryoria is abundant, it is common to find thalli in which the thalline filaments become conglutinated, forming brittle dead zones. After sampling Bryoria thalli across western Canada and the northwestern

ABSTRACT Species in the genus Tuber are ascomycetous fungi that produce hypogeous fruiting bodies commonly called truffles. These fungi are ecologically relevant owing to the ectomycorrhizal symbiosis they establish with plants. One of the most speciose lineages within Tuber is the Rufum clade, which is widely distributed throughout Asia, Europe, and North America and is estimated to include more than

ABSTRACT The recent description of the putative fungal pathogen of greenheart trees, Xylaria karyophthora (Xylariaceae, Ascomycota), prompted a study of its secondary metabolism to access its ability to produce cytochalasans in culture. Solid-state fermentation of the ex-type strain on rice medium resulted in the isolation of a series of 19,20-epoxidated cytochalasins by means of preparative high-performance
