“…Soft rot fungi are more common in hardwood, such as Eucalyptus spp., than in softwood which might be due to differences in the quality of the lignin (Hamed, 2013). Other genera, such as Scytalidium, Blastobotrys, Jaapia, or Mortierella, are also commonly found in decaying organic matter and produce enzymes that enhance the degradation of proteins in the wood of dead trees (Middelhoven & Kurtzman, 2007;Takahashi & Oda, 2008;Telleria, Dueñas, Melo, Salcedo, & Martín, 2015;Wagner et al, 2013).…”

Cryptococcosis is a fungal infection caused by members of the Cryptococcus gattii and C. neoformans species complexes. The C. gattii species complex has a strong environmental association with eucalypt hollows (particularly Eucalyptus camaldulensis), which may present a source of infection. It remains unclear whether a specific mycobiome is required to support its environmental survival and growth. Conventional detection of environmental Cryptococcus spp. involves culture on differential media, such as Guizotia abyssinica seed agar. Next‐generation sequencing (NGS)‐based culture‐independent identification aids in contextualising these species in the environmental mycobiome. Samples from 23 Australian tree hollows were subjected to both culture‐ and amplicon‐based metagenomic analysis to characterize the mycobiome and assess relationships between Cryptococcus spp. and other fungal taxa. The most abundant genera detected were Coniochaeta, Aspergillus, and Penicillium, all being commonly isolated from decaying wood. There was no correlation between the presence of Cryptococcus spp. in a tree hollow and the presence of any other fungal genus. Some differences in the abundance of numerous taxa were noted in a differential heat tree comparing samples with or without Cryptococcus‐NGS reads. The study expanded the known environmental niche of the C. gattii and C. neoformans species complexes in Australia with detections from a further five tree species. Discrepancies between the detection of Cryptococcus spp. using culture or NGS suggest that neither is superior per se and that, rather, these methodologies are complementary. The inherent biases of amplicon‐based metagenomics require cautious interpretation of data through consideration of its biological relevance.

“…All the strains were confirmed as belonging to this species, except four, which fermented galactose and did not produce purple colonies on DDM. These four strains were further analyzed by molecular methods that revealed that they were highly similar to the type strain of the recently described species Candida cretensis (Middelhoven & Kurtzman, 2007).…”

“…Candida cretensis is a new yeast species described from a single isolate from a decaying fungus (Middelhoven, 2004;Middelhoven & Kurtzman, 2007). This strain, CBS 9453 T , has been included in the Candida kruisii clade and cannot be distinguished phenotypically from C. kruisii, except for a delayed fermentation of cellobiose, which is not fermented by C. kruisii.…”

Four yeast strains were isolated from Spanish traditional fermented sausages (chorizo) spoiled by gas production. Using the classical identification procedures, they were identified as Debaryomyces hansenii. However, they fermented galactose and did not produce positive results in Debaryomyces differential medium (DDM), a growth medium highly specific for this species. Phylogenetic analysis showed identical sequences for the D1/D2 domain of the 26S rRNA gene and almost identical sequences for the 5.8S-ITS region with those of the recently described yeast species Candida cretensis. This result was confirmed by sequencing the gene encoding actin of the type and the new strains. Candida cretensis is a new species included in the so-called Candida kruisii clade that was described from a single strain, isolated from a decaying mushroom in Crete, Greece. The discovery of new strains of C. cretensis in fermented food expands its physiological and ecological diversity. With the description of these new strains isolated from food, three groups of strains can be distinguished within C. cretensis according to the restriction patterns of the intergenic spacer rRNA gene region and on the basis of some physiological properties that are of ecological relevance.

“…Smith & Y. Yamada (1990). Since then, the Trichomonascus clade has been expanded considerably by the description of seven novel Blastobotrys species (Middelhoven & Kurtzman, 2007;Kurtzman, 2007). In this paper, we report the isolation of four yeast strains representing haploid mating types of a novel Trichomonascus species, and propose a novel species with the name Trichomonascus apis sp.…”
