15-Deoxyoxalicine B (1) and decaturins A (2) and B (3) have been isolated from Penicillium decaturense and Penicillium thiersii, two previously undescribed species obtained as colonists of wood-decay fungi. The structures were determined by 2D NMR experiments and/or single-crystal X-ray diffraction analysis. These compounds are members of a rare structural class, and decaturins A and B feature ...

This supplement to the taxonomic monograph The Genera of Hyphomycetes summarises information on 23 accepted new genera and c. 160 species described in 2011. These include three dematiaceous genera (Funbolia, Noosia, Pyrigemmula, all related to Dothideomycetes), a bulbil-producing genus, Spiroplana (Pleosporales), and two endophytic genera, the sterile Periglandula (Clavicipitaceae), and the hya...

Cercosporoid fungi (former Cercospora s. lat.) represent one of the largest groups of hyphomycetes belonging to the Mycosphaerellaceae (Ascomycota). They include asexual morphs, asexual holomorphs or species with mycosphaerella-like sexual morphs. Most of them are leaf-spotting plant pathogens with special phytopathological relevance. The only monograph of Cercospora s. lat., published by Chupp...

Nine species of saprophytic hyphomycetes (anamorphic fungi), collected on plant debris from two different localities of southeast Florida, are recorded for the first time from the United States. They are: Anungitea fragilis, Beltraniella havanensis, Canalisporium caribense, Circinotrichum papakurae, Dictyosporium micronesicum, D. subramanianii, Dischloridium laeense, Gyrothrix verticillata and ...

The phylogenetic placement of the monotypic dematiaceous hyphomycete genus Xanthoriicola was investigated. Sequences of the nLSU region were obtained from 11 specimens of X. physciae, which formed a single clade supported both by parsimony (91 %), and maximum likelihood (100 %) bootstraps, and Bayesian Posterior Probabilities (1.0). The closest relatives in the parsimony analysis were species o...

The Eocene (~ 48.7 Ma, Ypresian-Lutetian) Princeton Chert of British Columbia, Canada, has long been recognized as a significant paleobotanical locality, and a diverse assemblage of anatomically preserved fossil plants has been extensively documented. Co-occurring fossil fungi also have been observed, but the full scope of their diversity has yet to be comprehensively assessed. Here, we present...
