Coffee pulp is one of the most underutilised by-products from coffee processing. For coffee growers, disposing of this agro-industrial biomass has become one of the most difficult challenges. This study utilised this potential biomass as raw material for polyphenolic antifungal agents. First, the proportion of biomass was obtained from the Arabica green bean processing. The yield of by-products was recorded, and the high-potency biomass was serially extracted with organic solvents for the polyphenol fraction. Quantification of the polyphenols was performed by High Performance Liquid Chromatography (HPLC), then further confirmed by mass spectrometry modes of the liquid chromatography–quadrupole time-of-flight (QTOF). Then, the fraction was used to test antifungal activities against Alternaria brassicicola, Pestalotiopsis sp. and Paramyrothecium breviseta. The results illustrated that caffeic acid and epigallocatechin gallate represented in the polyphenol fraction actively inhibited these fungi with an inhibitory concentration (IC50) of 0.09, 0.31 and 0.14, respectively. This study is also the first report on the alternative use of natural biocontrol agent of P. breviseta, the pathogen causing leaf spot in the Arabica coffee.

Two species of sooty mould-like taxa, were obtained from living leaves of Coffea arabica plants collected in Chiang Mai Province, Thailand. Differences in phenotypic and phylogenetic characteristics based on combined large subunit nuclear ribosomal DNA and internal transcribed spacer sequences indicated that the two isolates represent two novel species (Phaeosaccardinula coffeicola and Trichomerium chiangmaiensis) within the order Chaetothyriales. Phaeosaccardinula coffeicola (Chaetothyriaceae) is distinguished morphologically from related species by its smaller asci and ascospores. Trichomerium chiangmaiensis (Trichomeriaceae) is morphologically distinguishable from its phylogenetically related species by its smaller conidial arms. Detailed taxonomic descriptions and illustrations of the new species are provided.

Grasses are cosmopolitan yet an important component in ecology. The current human population readily relies on grasses as many Poaceae species provide staple carbohydrate sources and staple feed to livestock. Ecologically grass plays a vital role as a pioneer inhabitant as well as sustaining immense biodiversity within the community. Fungi play a pivotal role in maintaining and shaping the grass communities. Fungi occur on grasses as commensals, saprobes, and pathogens. Each fungal community associated with grasses is responsible for the specific ecological property of the grass community, either in silviculture or polyculture. Hence, grass fungi drawn much attention from researchers. The taxonomy of grass fungi dates back to 1800s. However, up-to-date collective worldwide account for grass fungi is still lacking. In thi study, we compiled all the taxonomically valid data of Ascomycetous grass fungi in a checklist. The section Ascomycota comprises 3,165 fungal species among 207 families, 70 orders, and 11 classes. The majority of the species are represented by Dothideomycetes (1,367) and Sordariomycetes (944). This study is the first worldwide checklist of Ascomycetous grass fungi.

A novel taxon was found as epiphytic sooty molds on Syngonium podophyllum from Thailand. A new genus, Alloscorias gen. nov. is established to accommodate a novel taxon, named A. syngonii. The morphological characters of the species are observed in culture. Phylogenetic analyses of a combined dataset of LSU, ITS, TEF-1α and RPB2 sequence data together with morphological support that Alloscorias is a distinct genus within Readerielliopsidaceae (Capnodiales). Detailed descriptions and illustrations are provided in this paper.
