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.

“…Basidiomata formation in ectomycorrhizal fungi is a complex phenomenon because a set of specific physical, nutritional and biotic factors is required, as well as the obligate dependency towards the host plant. In general, these conditions have been poorly studied in the case of edible ectomycorrhizal mushrooms (Kües and Liu, 2000;Wessels, 1993;Yamada et al, 2007).…”

“…Several studies have shown that environmental conditions are crucial to basidioma formation in ectomycorrhizal fungi, including temperature, carbon dioxide concentrations in the atmosphere, moisture, salinity (Kües and Liu, 2000;Wessels, 1993), fertilization regime (Debaud and Gay, 1987;Godbout and Fortin, 1990), relative humidity (Yamada et al, 2007), the contribution of host carbohydrates (Lamhamedi et al, 1994), and the abundance of ectomycorrhizal colonization of the fungal species of interest (Guerin-Laguette et al, 2013;2014;Pilz and Molina, 2001).…”

“…It has previously been reported that the factors influencing basidiomata formation in edible ectomycorrhizal mushrooms associated with their plant hosts are mainly temperature, fertilization regime (Debaud and Gay, 1987;Ellis et al, 1999), relative humidity (Yamada et al, 2007), the contribution of host carbohydrates and even electrical impulses (Ohga et al, 2001).…”

Type of Light and Formation of Basidiomata of Two Species of Edible Ectomycorrhizal Mushrooms Associated With Neo-Tropical Pines and the Description of Basidiomata Development

Ectomycorrhiza is a mutualistic symbiosis of paramount importance in the functioning of forest ecosystems. Therefore, inoculation with ectomycorrhizal fungi, particularly edible species, has gained enormous relevance in the production of forest trees with economic importance. However, due to technical difficulties for the cultivation of ectomycorrhizal basidiomata associated with their host trees, factors influencing basidiomata formation have not been fully understood. This study evaluated the effect of two light wavelengths on the production of basidiomata of two edible ectomycorrhizal mushroom species (Hebeloma leucosarx and Laccaria bicolor) associated with two neo-tropical trees, Pinus montezumae and Pinus greggii. The two fungal species evaluated are widely used as food and sold in traditional markets in México. In general, the type of light differentially influenced the basidioma formation of these fungi in association with host seedlings in greenhouse during six years. Increased basidioma formation of H. leucosarx was observed associated with trees growing in pots covered with yellow filters with a wavelength of ~590 nm compared with those covered with red filters with a wavelength of ~660 nm. Meanwhile, the opposite trend was observed in basidiomata of L. bicolor. The host tree species influenced the formation of basidiomata. Hebeloma leucosarx produced more basidiomata in association with P. montezumae than with P. greggii. In addition, a description of basidiomata formation from very young stages previous to senescence is provided for both mycobionts. To our knowledge, this is the first record of the effect of light wavelengths on the production of basidiomata of edible ectomycorrhizal mushrooms, demonstrating that this phenomenon is more complex than previously believed.

“…Gray is one of the well-known edible ectomycorrhizal (ECM) fungi with a worldwide distribution. Over the course of past decades, assessment of ECM fungal sporocarp production has been carried out, and some pot culture trials have been conducted to determine the golden edible ECM fungal growth, primordium, and basidiocarp formation (Yamada et al 2001(Yamada et al , 2007, which are greatly influenced by various factors such as fatty acids (Unestam and Sun 1995), wood ash (Hagerberg and Wallander 2002), surfactants or vegetable oil (GuerinLaguette et al 2003), and microbial interaction (Gamalero et al 2003). Among these factors, much attention has been devoted to the bioactive compounds that improve the process of mycelial growth (Unestam and Sun 1995).…”

Growth promotion of Suillus luteus by adenosine in vitro

In this work, adenosine has been shown to stimulate Suillus luteus mycelial growth, branching, and aggregates on solid substrate. Adenosine promoted S. luteus mycelial growth and branching, and the fungus responded significantly at a concentration as low as 0.01 mg/ml. The highest mycelial biomass and density of three strains were observed at 0.16 mg/ml in SNP-20, 0.08 mg/ml in SAF-501, and 0.16 mg/ml in PT-501. Adenosine enhanced mycelial aggregate at concentration of 0.02 mg/ml in SNP-20. The study suggests that adenosine promotes S. luteus mycelial growth, branching, and aggregation. Thus, it may be a good candidate as a biological elicitor of mycelial growth for S. luteus.
