APROXIMACIONES A LA ETNOMICOLOGÍA MAYA
Los pueblos mayas habitan una región biológicamente megadiversa y tradicionalmente hacen uso diversificado de sus recursos. Desde la etnomicología —disciplina que estudia la relación entre grupos humanos y hongos— se cuenta con amplia evidencia del conocimiento y uso de estos organismos entre tales grupos étnicos. Tal evidencia se extiende hasta tiempos prehispánicos con hongos piedra, códices y crónicas. Actualmente se tiene conocimiento de 134 especies comestibles —ya sean para autoconsumo o venta— y alrededor de 40 hongos medicinales en la región. Asociados con estos usos, existen conocimientos morfológicos, fenológicos, ecológicos y culinarios de los hongos, así como desarrollados esquemas de nomenclatura y clasificación, el reconocimiento de 36 especies consideradas tóxicas y la presencia de hongos en diferentes narrativas.
APPROACHES TO MAYAN ETHNOMYCOLOGY
The Mayan peoples inhabit a biologically megadiverse region and have traditionally made a diversified use of their resources. Ethnomycology —the discipline that studies the relationship between human groups and mushrooms— provides extensive evidence of the knowledge these ethnic groups have of mushrooms and their use. Evidence can be traced back to pre-Hispanic times with mushrooms carved in stone and their presence in codices and chronicles. In the region, 134 edible species —either for consumption or for trade— are currently known, as well as about 40 medicinal mushrooms. Morphological, phenological, ecological and culinary data as well as nomenclature and classification schemes are associated with these uses. The identification of 36 species considered toxic and the presence of mushrooms in different narratives is also part of this body of knowledge
Comparación de la disponibilidad de hongos comestibles en tierras altas y bajas de Chiapas y sus implicaciones en las estrategias tradicionales de aprovechamiento
Background and Aims: Wild edible mushroom traditional management strategies have been described for both highlands and lowlands in Mexico. It seems that, in the lowlands, the usage of this resource is lower than in the highlands. Ecological ethnomycology is concerned with understanding how certain ecological patterns in mushrooms influence traditional management strategies. In this study we present a comparison between the edible mushrooms’ fruit body availability in two distinct ecological units: The Highlands of Chiapas and the Lacandon Rainforest. Our hypothesis was that the fruit body availability is higher in both the highlands and preserved vegetation, which might explain a greater usage in these ecosystems, as well as the opportunistic usage of mushrooms in the lowlands.Methods: During 2009 and 2010, we monitored the fruit body abundance, biomass, spatial and temporal frequencies, as indicators of edible mushroom availability in rectangular transects in three sites per ecological setting (highlands/lowlands) both in preserved vegetation sites and agroecosystems in Chiapas, Mexico.Key results: In the highlands, a greater richness (35 ethnotaxa) and biomass production (12,345.2 g) was recorded, but the lowlands yielded a greater number of fruit bodies (3212) and a higher spatial and temporal frequency (76.6% and 40% respectively).Conclusions: In both ecological settings, edible mushroom availability allow their use; however, it has different ecological traits. This may explain why, in the highlands, people use a more diverse array of species and prefer those of greater biomass. Contrastingly, in the lowlands less species are used, but they are more abundant and have a greater spatial and temporal frequency. Our data demonstrate that the lowlands and agroecosystems are spaces with edible mushroom availability comparable to that of highland forests.Antecedentes y Objetivos: Las estrategias tradicionales de aprovechamiento de hongos silvestres comestibles han sido descritas de tierras altas y bajas en México. No obstante, al parecer en las tierras bajas el aprovechamiento de especies es menor que en las altas. La etnomicología ecológica se interesa en comprender cómo ciertos patrones ecológicos en los hongos pueden orientar las estrategias tradicionales de aprovechamiento. Este estudio presenta una comparación entre la disponibilidad de esporomas de hongos comestibles en dos condiciones ecológicas, Los Altos de Chiapas y la Selva Lacandona. Se plantea la hipótesis de que la disponibilidad de esporomas es mayor tanto en tierras altas como en sitios con vegetación conservada y, por tanto, esto podría explicar un mayor beneficio en dicho piso ecológico y el aprovechamiento oportunista en tierras bajas. Métodos: Durante 2009 y 2010 se monitoreó la abundancia, biomasa, frecuencia espacial y temporal como indicadores de disponibilidad, en transectos rectangulares en tres localidades de cada piso en Chiapas, México, en vegetación conservada y agroecosistemas. Resultados clave: En tierras altas existió una mayor riqueza (35 etnotaxones) y una mayor producción de biomasa (12,345.2 g), mientras que en tierras bajas se registró una mayor abundancia de esporomas (3212), frecuencia espacial (76.6%) y temporal (40%).Conclusiones: En ambos pisos ecológicos existe disponibilidad del recurso que permite su aprovechamiento; sin embargo, este se comporta diferente en términos ecológicos. Esto puede explicar porque en tierras altas las personas utilizan una mayor cantidad de especies y la preferencia por aquellas de mayor biomasa. Por el contrario, en tierras bajas se aprovecha un menor número de especies, pero más abundantes, y con mayor presencia espacial y temporal. Los datos aquí presentados muestran que las tierras bajas y los agroecosistemas son espacios con una disponibilidad de hongos tan importante como la de los bosques de tierras altas
Phlebopus beniensis (Singer & Digilo) Heinem. & Rammeloo (Boletinellaceae, Basidiomycota, Fungi): novo registro para o Estado de São Paulo, Brasil e notas etnomicológicas
Phlebopus is a genus of boletoid fungi that produces conspicous basidiomes with large dimensions. The genus is represented in Brazil by six species distributed in eight States, with P. beniensis being here newly reported from the State of São Paulo, Southeastern Brazil. Therefore, the aim of this study is to report the occurrence of this species in São Paulo State based on specimens from Southwestern region of the State, as well as to present ethnomycological notes, including the first report of the species edibility.Phlebopus é um gênero de fungos boletoides que produz basidiomas conspícuos, de grandes dimensões. O gênero está representado no Brasil por seis espécies distribuídas em oito Estados, porém, P. beniensis ainda não havia sido registrada para o Estado de São Paulo, Sudeste do Brasil. Sendo assim, o objetivo deste trabalho é registrar a ocorrência da espécie para o Estado de São Paulo com base em espécimes da região sudoeste do Estado, assim como apresentar notas etnomicológicas, incluindo o primeiro registro de comestibilidade da espéci
Knowledge and use of edible mushrooms in two municipalities of the Sierra Tarahumara, Chihuahua, Mexico
Background: The Sierra Madre Occidental of Chihuahua in Northern Mexico is inhabited by indigenous Raramuris,
mestizos, and other ethnic groups. The territory consists of canyons and ravines with pine, oak and pine-oak forests in the higher plateaus. A great diversity of potentially edible mushrooms is found in forests of the Municipalities of Bocoyna and Urique. Their residents are the only consumers of wild mushrooms in the Northern Mexico; they have a long tradition of collecting and eating these during the “rainy season.” However, despite the wide diversity of edible mushrooms that grow in these areas, residents have a selective preference. This paper aims to record evidence of the knowledge and use of wild potentially edible mushroom species by inhabitants of towns in the Sierra Tarahumara of Chihuahua, Mexico.
Method: Using a semi-structured technique, we surveyed 197 habitants from seven locations in Urique, Bocoyna, and the Cusarare area from 2010 to 2012. Known fungi, local nomenclature, species consumed, preparation methods, appreciation of taste, forms of preservation, criteria for differentiating toxic and edible fungi, other uses, economic aspects, and traditional teaching were recorded. To identify the recognized species, photographic stimuli of 22 local edible species and two toxic species were used.
Results: The respondents reported preference for five species: Amanita rubescens, Agaricus campestris, Ustilago
maydis, Hypomyces lactifluorum, and the Amanita caesarea complex. No apparent differences were found between ethnic groups in terms of preference, although mestizos used other species in Bocoyna (Boletus edulis and B. pinophilus). Some different uses of fungi are recognized by respondents, i.e. home decorations, medicine, as food in breeding rams, etc.
Conclusion: The studied population shows a great appreciation towards five species, mainly the A. caesarea
complex, and an apparent lack of knowledge of nearly 20 species which are used as food in other areas of Mexico. There are no apparent differences among Sierra inhabitants in terms of gender, occupation, or language regarding the recognition and consumption of species. The rejection of certain species is due mainly to fear of
poisoning and the traditional selective teaching of families in the mountain communities of the Sierra
Tarahumara
Cultural significance of wild mammals in mayan and mestizo communities of the Lacandon Rainforest, Chiapas, Mexico
Sociodemographic differences in the cultural significance of edible and toxic mushrooms among Tsotsil towns in the Highlands of Chiapas, Mexico
Abstract Background Mushrooms are important forest resources, mostly as food, despite the serious health threat posed by toxic species. In the Highlands of Chiapas, numerous wild mushroom intoxications have been registered. While Chiapas has been vastly studied from an ethnomycological perspective, no certainty exists as to how nomenclature systems differentiate edible and toxic species, which species are most culturally significant, and whether sociodemographic factors relate to how well-known they are in the Highlands of Chiapas. This paper evaluates which are the most culturally significant edible and toxic wild mushroom species in seven Tsotsil communities from this region and whether differences exist in their knowledge relating to different sociodemographic subsets (gender, schooling, and occupation). The hypothesis that there is a difference in the number of species that people mention, as well as the number of times each ethno-taxon is mentioned, between people from different social groups was tested. Methods With consent, 133 Tsotsil people from seven communities were interviewed. Interviews focused on local systematics and free listings of edible and toxic mushrooms. Qualitative and quantitative analyses were performed, including multivariate methods and non-parametric statistics. Results Twenty-five edible and 15 toxic taxa were mentioned. Some directly correspond to Linneanean species, while others are subdifferentiated or supradifferentiated. Only 62% of the interviewees named toxic mushrooms. The most frequently mentioned edible taxa were Amanita hayalyuy and A. jacksoniii, Agaricus spp., and Armillaria mellea. The most frequently mentioned toxic species were Amanita muscaria, Suillellus luridus, and Russula emetica. Significant differences in the number of mentioned edible ethnotaxa were found only among different occupations and schooling. The models including schooling interacting with either gender or occupation are better supported. Significant differences in the number of times toxic ethnotaxa are mentioned were found only between men and women. Conclusions The Tsotsil region of the Highlands of Chiapas is where the most average mushroom species are recognized state-wide. Schooling and occupation seem most determinant for people to know more or less species of mushrooms, while gender appears irrelevant. People with no studies and field-related occupations name more species. Identification criteria to distinguish edible from toxic species seem to rest not on detailed recognition of the second set but precise knowledge of the first
