“…The occurrence of cryptic species will also affect biodiversity assessments in a given habitat and therefore studies based only on morphology might underestimate diversity [65] . Indeed, several authors have suggested that next to the application of different media to culture rare species, the exact identification of cryptic diversity by molecular markers is an important factor that will counter underestimation of yeast diversity found in a given area [66] – [67] .…”

Species Accumulation Curves and Incidence-Based Species Richness Estimators to Appraise the Diversity of Cultivable Yeasts from Beech Forest Soils

BackgroundYeast-like fungi inhabit soils throughout all climatic zones in a great abundance. While recent estimations predicted a plethora of prokaryotic taxa in one gram of soil, similar data are lacking for fungi, especially yeasts.Methodology/Principal FindingsWe assessed the diversity of soil yeasts in different forests of central Germany using cultivation-based techniques with subsequent identification based on rDNA sequence data. Based on experiments using various pre-cultivation sample treatment and different cultivation media we obtained the highest number of yeasts by analysing mixed soil samples with a single nutrient-rich medium. Additionally, several species richness estimators were applied to incidence-based data of 165 samples. All of them predicted a similar range of yeast diversity, namely 14 to 16 species. Randomized species richness curves reached saturation in all applied estimators, thus indicating that the majority of species is detected after approximately 30 to 50 samples analysed.Conclusions/SignificanceIn this study we demonstrate that robust species identification as well as mathematical approaches are essential to reliably estimate the sampling effort needed to describe soil yeast communities. This approach has great potential for optimisation of cultivation techniques and allows high throughput analysis in the future.

“…Furthermore, most species of the genus produce extracellular starch-like compounds. Species forming the polyphyletic genus Cryptococcus are dispersed in the orders Tremellales, Trichosporonales, Filobasidiales and Cystofilobasidiales (Fell et al , 2000; Golubev et al , 2006).…”

Three strains were isolated from the nostrils of a koala and the surrounding environment in a Japanese zoological park. Sequence analysis of the nuclear rDNA internal transcribed spacer (ITS) region and the large subunit rDNA D1/D2 domains in addition to physiological and morphological studies indicated that the isolates represent a single novel species belonging to the basidiomycetous genus Cryptococcus (Tremellales, Tremellomycetes, Agaricomycotina). Phylogenetic analysis based on D1/D2 and ITS regions revealed that the novel species belongs to the Fuciformis clade. The name Cryptococcus yokohamensis sp. nov. is proposed to accommodate these isolates with strain JCM 16989T ( = TIMM 10001T = CBS 11776T = DSM 23671T) as the type strain.
