“…The third species, A. benjaminii, is closely allied with A. perpusillus, and like the latter lacks antheridia and the whole diminutive thallus; these 2 species are the only ones not associated with the Limnichidae. The 3 new species described here bring to 93 the number of Laboulbeniales reported from Ecuador (Rossi, 2009;Rossi, 2010;Rossi and Santamaría, 2010;Rossi, 2011;Rossi and Santamaría, 2012;Barragán et al, 2013;Goldmann et al, 2013;Rossi et al, 2013). This figure is relatively high: as to the American continent, higher numbers of Laboulbeniales have only been recorded in 3 much larger states (Argentina, Brazil, and United States).…”

“…Laboulbenia triarthronis is the first species of Laboulbenia reported on Coleoptera Leiodidae. The beetles of this family of insects are the hosts of the other 14 genera in the Laboulbeniales , 4 of which are found only on Leiodidae (Benjamin 1955 ; Rossi and Santamaria 2012 ; Haelewaters and Rossi 2017 ).…”

This article is the 13th contribution in the Fungal Diversity Notes series, wherein 125 taxa from four phyla, ten classes, 31 orders, 69 families, 92 genera and three genera incertae sedis are treated, demonstrating worldwide and geographic distribution. Fungal taxa described and illustrated in the present study include three new genera, 69 new species, one new combination, one reference specimen and 51 new records on new hosts and new geographical distributions. Three new genera, Cylindrotorula ( Torulaceae ), Scolecoleotia ( Leotiales genus incertae sedis ) and Xenovaginatispora ( Lindomycetaceae ) are introduced based on distinct phylogenetic lineages and unique morphologies. Newly described species are Aspergillus lannaensis , Cercophora dulciaquae , Cladophialophora aquatica , Coprinellus punjabensis , Cortinarius alutarius , C. mammillatus , C. quercoflocculosus , Coryneum fagi , Cruentomycena uttarakhandina , Cryptocoryneum rosae , Cyathus uniperidiolus , Cylindrotorula indica , Diaporthe chamaeropicola , Didymella azollae , Diplodia alanphillipsii , Dothiora coronicola , Efibula rodriguezarmasiae , Erysiphe salicicola , Fusarium queenslandicum , Geastrum gorgonicum , G. hansagiense , Helicosporium sexualis , Helminthosporium chiangraiensis , Hongkongmyces kokensis , Hydrophilomyces hydraenae , Hygrocybe boertmannii , Hyphoderma australosetigerum , Hyphodontia yunnanensis , Khaleijomyces umikazeana , Laboulbenia divisa , Laboulbenia triarthronis , Laccaria populina , Lactarius pallidozonarius , Lepidosphaeria strobelii , Longipedicellata megafusiformis , Lophiotrema lincangensis , Marasmius benghalensis , M. jinfoshanensis , M. subtropicus , Mariannaea camelliae , Melanographium smilaxii , Microbotryum polycnemoides , Mimeomyces digitatus , Minutisphaera thailandensis , Mortierella solitaria , ...

“…Members of the order are most often microscopical, typically measuring 100–1,000 μm in length (Santamaria, ; Weir & Blackwell, ). The order is one of the largest within the Ascomycota, with more than 2,000 described species in around 140 genera (Rossi & Santamaria, ). The expected species richness is considerably higher, 15,000–75,000 species based on the number of suitable hosts and the high host specificity displayed by many representatives of the order (Weir & Hammond, ).…”

We have developed a reliable technique for extracting DNA from single microscopic fungal thalli, including efficient cell disruption and transfer of cell content for subsequent polymerase chain reaction (PCR). The technique was primarily developed for members of the ascomycete order Laboulbeniales, which are minute fungi with tough cell walls that are exceedingly difficult to disrupt with standard extraction techniques. Our method makes routine amplification of DNA from single thalli possible, even from small species or poorly developed individuals. DNA release is accomplished in an entirely mechanical manner using an arbor press fitted with custom‐made components. This approach has eliminated additional treatment such as laborious freeze‐thaw cycles, enzymes, or lysing agents. The overall PCR success rate of 89% is comparable to or better than alternative protocols that make use of substantially larger amounts of fungal tissue. From 97% of the successful PCRs a total of 156 sequences from four gene regions were produced. Being able to restrict DNA extractions to a single thallus is critical to all genetic studies requiring data at the level of individual, e.g. population genetics. As all researchers working with minute uncultivable organisms in many respects face the same problems (effective handling of the material, small quantities of DNA etc.), the methodology described here has a potential to be widely applicable. Necessary custom‐made components can be manufactured at fairly low cost by any precision‐tool workshop using our detail drawings.
