“…As far as we know, of the 10 most abundant phylotypes detected in the cave only Kraurogymnocarpa trochleospora has not been associated with arthropods. It was isolated from soils in Indonesia, USA and Monaco (Udagawa and Uchiyama 2001).…”

Aims: To determine the major components of the fungal population present in Lascaux Cave, France. The ceiling, walls, sediments and soil were colonized by Fusarium solani in 2001 and later, in 2006, black stains appeared. However, the origin of the successive fungal invasions is unknown as well as the ecology of the cave. Methods and Results: The primers nu‐SSU‐0817F and nu‐SSU‐1536R were used for the direct amplification of fungal 18S‐rDNA sequences from 11 samples. A total of 607 clones were retrieved. Eight out of the ten most abundant phylotypes corresponded to fungi associated with arthropods and represented about 50% of the clones. Conclusions: Entomophilous fungi play an important role in the cave and arthropods contribute to the dispersion of spores and fungal development. Significance and Impact of the Study: Choosing appropriate targets for control of fungal dispersal is dependent on knowing the causes of fungal colonization. A control of the arthropod populations seems to be a need in order to protect the rock art paintings in Lascaux Cave.

“…There are estimated to be as many as eight Psilocybe hallucinogenic species containing psychoactive alkaloids, such as psilocybin and psilocin. K. trochleospora (Pseudoarachniotus trochleosporu) is usually isolated from soils with high organic content and have high cellulolytic activity (Udagawa and Uchiyama 2001).…”

Diversity of soil fungal communities of Cerrado and its closely surrounding agriculture fields

et al. 2008

Cerrado is a savanna-like region that covers a large area of Brazil. Despite its biological importance, the Cerrado has been the focus of few microbial diversity studies. A molecular approach was chosen to characterize the soil fungal communities in four areas of the Cerrado biome: a native Cerrado, a riverbank forest, an area converted to a soybean plantation, and an area converted to pasture. Global diversity of fungal communities in each area was assessed through Ribosomal intergenic spacer analysis which revealed remarkable differences among the areas studied. Sequencing of approximately 200 clones containing 18S rDNA sequences from each library was performed and, according to the genetic distance between sequences, these were assigned to operational taxonomic units (OTUs). A total of 75, 85, 85, and 70 OTUs were identified for the native Cerrado, riverbank forest, pasture, and soybean plantation, respectively. Analysis of sequences using a similarity cutoff value of 1% showed that the number of OTUs for the native Cerrado area was reduced by 35%; for the soybean plantation, a reduction by more than 50% was observed, indicating a reduction in fungal biodiversity associated with anthropogenic activity. This is the first study demonstrating the anthropogenic impact on Cerrado soil fungal diversity.

“…Only one species of Gymnoascus forms bivalvate ascospores, G. ruber, whose ascospores are smooth, unlike Kraurogymnocarpa . The original authors did not perform a molecular analysis, but stated in their paper that such studies may supply more evidence on their relationships ( Udagawa & Uchiyama 2001 ). Sigler et al (2002) sequenced the SSU region of an ex-type culture of Kraurogymnocarpa trochleospora and showed that it was distinct from five species of five different genera of Gymnoascaceae , all of which are now placed in Gymnoascus ( Sole et al 2002 ).…”

A new species, Gymnoascus verrucosus sp. nov., isolated from soil from Kalyan railway station, Maharashtra, India, is described and illustrated. The distinctive morphological features of this taxon are its verruculose ascospores (ornamentation visible only under SEM) and its deer antler-shaped short peridial appendages. The small peridial appendages originate from open mesh-like gymnothecial ascomata made up of thick-walled, smooth peridial hyphae. The characteristic morphology of the fungus is not formed in culture where it has very restricted growth and forms arthroconidia. Phylogenetic analysis of different rDNA gene sequences (ITS, LSU, and SSU) demonstrates its placement in Gymnoascaceae and reveal its phylogenetic relatedness to other species of Gymnoascus, especially G. petalosporus and G. boliviensis. The generic concept of Gymnoascus is consequently now broadened to include species with verruculose ascospores. A key to the accepted 19 species is also provided.
