Although in temperate Mexico [ 34 , 44 , 59 , 60 , 64 , 69 , 72 , 73 , 74 , 75 ], Burkina Faso [ 41 ], and Hungary [ 27 ] most of the vendors in markets are women Figure 3 A, 3 B. Even though men could accompany them, women establish prices and bargain with customers.
In temperate regions of Mexico there is a market for hallucinogenic species used for recreational purposes. In Mexican tropical regions, where wild mushroom sale in markets is marginal [ 65 ], men are in charge of taking customers foraging for hallucinogenic species.
In some places, even ceremonies for tourists are led by shamans of either sex [ 76 ]. Open image in new window Figure 3 Women and children selling mushrooms and sharing traditional mycological knowledge. Traditional practices are conserved in local markets where women usually barter the mushrooms that they do not sell during the day for other products.
By engaging in trading, women make the most of the energy spent in collecting and optimize their income, while the remaining mushrooms are used as food [ 69 ]. Barter also has a remarkable social function as a means of constructing and strengthening social bonds [ 65 , 73 ].
Women often manage the income resulting from mushroom sale [ 44 ].
Thus, mushrooms are a natural resource that allows women to gain some money, become economically independent, acquire essentials goods, and complement their diet [ 36 , 43 ]. Markets provide a space in which local knowledge is shared and transmitted [ 11 , 44 ]. Mushroom vendors coax potential buyers into getting the different varieties they offer by sharing recipes, telling stories, and indicating the proper procedures to ensure safe consumption.
Thus, women as vendors permit urban residents to reincorporate wild mushrooms as a dietary choice. It is constructed from a base of inherited knowledge modified by processes of enrichment innovation, experimentation , loss transculturation, acculturation , and transformation syncretism [ 77 , 78 ].
Rural women are particularly vulnerable in the face of global phenomena such as national policies, economical and ecological crises, food shortage, migration, urbanization, marginalization, transculturation, acculturation, environmental transformation, deforestation, and pollution [ 79 ]. Local knowledge serves them as an instrument to deal with these situations.
Because local practices are developed through a continuous interaction with the environment, they also tend to be the least destructive means of appropriation. National and international conservation programs currently integrate local knowledge as a strategy to both preserve the environment and promote local identities.
When women are the primary collectors or sellers of mushrooms, they also become the main teachers of local mycological knowledge. In Poland, sex differences in knowledge transmission are slight, although fathers are most mentioned as the first teachers, and boys learn at a younger age than girls [ 38 ].
During the first years in which children learn about mushrooms, mothers often encourage them to foray for them [ 36 , 60 ]. They bring their children along and teach them the names of the mushrooms they find.
Then the wives understand and cook them… their kids explain how. Women are open to other sources of knowledge exchange such as workshops, forums, mushrooms fairs, technical seminars, and training courses. Women not only transmit their inherited knowledge, they also generate new knowledge by experimentation and appropriation. In Mexico, there is evidence that women have experimented with the consumption of species not previously recognized as edible in their communities.
This is accomplished through an intense observation of the biology and ecology of the suspected edible species. When these species share characteristics with other edible species, they are gathered, cooked, and served to a dog several times.
If the dog survives, they taste it themselves in small quantities. When they are sure the mushroom is harmless, they serve it to their families. Also, we have observed in Tlaxcala, Mexico, the novel use of Lyophyllum sp. While soaking this edible mushroom, women discovered it softened their skin. Dugan [ 51 ] has documented one of the most interesting chapters in mycology history. Challenges women face during the mushroom appropriation process Although mushrooms are considered a free access resource in temperate regions [ 22 ], collectors are currently being limited in their access to the forests or are required to pay a fee.
Each time we go we will have to pay… but sometimes we do not sell much.
In some places of Burundi, women claim rights on portions of land where edible Termitomyces fungi fruit [ 80 ]. Indiscriminate logging has destroyed forests making it more expensive to obtain mushrooms. It would take three or four hours if we walked. In several regions a decrease in wild mushroom production has been documented. In Europe acid rain and forest soil nitrification have modified mushroom communities leading to local extinctions of several species like Cantharellus cibarius [ 81 ].
In Japan nematode plagues have destroyed populations of Tricholoma matsutake, one of the most valued edible mushrooms [ 82 ]. Very little [grows], there is not as much as before. They attribute this to logging, damage by livestock, change in rain patterns, and competition. There are dangers that are inherent to gathering activities in the forest. While gatherers recognize these, they are not an impediment to them. Mushroom collectors, as independent workers, face these dangers without social health benefits.
They have few solutions for these trials. Nonetheless, they persist in mushroom gathering because they value this activity as a source of income and as part of their cultural identity Figure 3 D. The most important tools they have to face these challenges are their local knowledge and their skills.
These allow them to adapt to changing environmental and social conditions. Conclusions The unique nature of local mycological knowledge distinguishes it from both ethnobotanical and ethnozoological knowledge. This knowledge is based upon fungal biology, ecology, and metabolism, and impacts both management and perception. In rural areas, women are usually unemployed, dedicating themselves to household and subsistence activities. Mushrooms provide a source of income and nourishment, contributing to the food security of this vulnerable group.
The literature indicates that, in many regions of the world, they are the principal mushroom collectors. They also play a central role on mushroom processing both for self-consumption and sale. All students are expected to be in attendance unless prior arrangements have been made with Dr Cooper.
Due to extenuating circumstances, the examination dates may be changed at the discretion of Dr. Examinations are to be taken without assistance from other students.
If you are aware of any student cheating or having a copy of the current exam, please contact the instructor. Academic dishonesty in any form will not be tolerated in this course. Penalties for such action will be enforced see Academic Dishonesty above. At all times, students are expected to exhibit behavior appropriate for young or even older adults.
Such behavior is delimited by University policy. Inappropriate behavior, including disrespect for Dr. Cooper, is subject to expulsion from one or more lecture sessions without the opportunity to begin or complete the assigned exercises.
In cases of extremely inappropriate behavior, Dr. Cooper will recommend more severe sanctions including dismissal from the University.

For single spore cultures, actively growing Pd plates mm X 15 mm of over three weeks old were flooded with 2 ml of sterile water and gently swirled to release the spores conidia. The spore suspension was vortexed for one minute to avoid clumping of spores. About 1 ml of sterile water was added in the process to help to spread the spores uniformly.
The plate was viewed under a dissecting microscope and concentration of the spore suspension was adjusted so that each plate had 20—30 spores. Once the spores germinated, an agar plug was cut containing hyphae from the single germinating spore without damaging growing hyphae and then plated on a regular SDA plate to culture.
For hyphal tip culture, we used the protocols described by Kanematsu et. We plated spore suspension on regular SDA plates as described above but when spores geminated and mycelia mats were formed they were gently overlaid with sterile Whatman cellulose filter paper soaked in SDB.
The plates were then cultured for an additional two weeks until the fungal hyphae penetrated the filter paper and started growing on the upper surface. At that point the filter paper was removed and its upper surface was scraped gently and hyphal segments were suspended in sterile water.
The method produced hyphal segments ranging from 4—8 cells in length that were appropriate for the hyphal tip culture. The hyphal segment suspension was then plated on SDA plates adjusting the concentration so that each plate had uniform distribution of 20—30 hyphal segments. Finally agar plugs grown from individual hyphal segments were cultured in separate plates to obtain a pure culture.
All Pd isolates from Pennsylvania, one from Vermont and one from Indiana used in this study were isolated and cultured in our laboratory. In addition, we obtained five isolates of Geomyces sp. Robert A. About 0.
The sequences obtained were trimmed for plasmid and primer sequences and assembled using de novo assembly in Geneious version 8. All cloning and sequence analysis was based on the dsRNA from the LB isolate cultured from a little brown bat from Pennsylvania. The amplicons were cloned followed by sequence determination using Sanger sequencing. The membranes were UV-cross-linked in a Stratalinker at J. Hybridization and washings were carried out as described by Li et al. Virus purification Virus particles were purified following methods described by Sanderlin and Ghabrial [ 41 ] with some modifications.
Eight g of lyophilized mycelia of Pd isolate BB was ground to powder in the presence of liquid nitrogen. The homogenates were mixed with extraction buffer 0.
The virus containing supernatant was then subjected to two cycles of differential centrifugations low speed at rpm for 15 min and ultracentrifuge at 35, for 1.
