We introduce 15 new species of Penicillium isolated from a diverse range of locations, including Canada, Costa Rica, Germany, Italy, New Zealand, Tanzania, USA and the Dry Valleys of Antarctica, from a variety of habitats, including leaf surfaces in tropical rain forests, soil eaten by chimpanzees, infrabuccal pockets of carpenter ants, intestinal contents of caterpillars and soil. The new species are classified in sections Aspergilloides (1), Canescentia (2), Charlesia (1), Exilicaulis (3), Lanata-Divaricata (7) and Stolkia (1). Each is characterised and described using classical morphology, LC-MS based extrolite analyses and multigene phylogenies based on ITS, BenA and CaM. Significant extrolites detected include andrastin, pulvilloric acid, penitrem A and citrinin amongst many others.

Background: Bacillus species produce antimicrobial lipopeptides (LPs) and methyl jasmonate (MeJA) induces resistance in harvested fruits against postharvest pathogens. However, there is limited evidence of the combined efficacy of Bacillus LPs and MeJA to suppress postharvest diseases.
Results: This study presents the combined effect of Bacillus LPs and MeJA to suppress P.

Sugar beet roots in Idaho are held under ambient conditions in outdoor storage piles which can lead to fungal growth and rot and substantial sucrose loss. Thus the incidence, distribution, and pathogenicity of fungi associated with fungal growth on the surface of sugar beet roots on top of outdoor piles was investigated. The surface fungal growth on sugar beet roots held on top of 14 Idaho outdoor piles [tarped ventilated (TV) piles and piles with no tarps or ventilation (NTV) at 7 locations] was assessed in 2018-19 and 2019-20.

The histone acetylation modification is a conservative post-translational epigenetic regulation in fungi. It includes acetylation and deacetylation at the lysine residues of histone, which are catalyzed by histone acetyltransferase (HAT) and deacetylase (HDAC), respectively. The histone acetylation modification plays crucial roles in fungal growth and development, environmental stress response, secondary metabolite (SM) biosynthesis, and pathogenicity.

The increasing demand for sustainable alternatives to conventional antifungal agents has prompted extensive research into the antifungal properties of plant essential oils (EOs). This study investigates the use of EOs mixture (Origanum vulgare, Moringa oleifera, and Cinnamomum verum) for controlling fungal deterioration in wall paintings at the archaeological Youssef Kamal Palace in Nag Hammadi, Egypt. Fungal isolates were collected from deteriorated wall paintings and identified using phenotypic and genotypic analyses.
