In this work, the phenotypic variation in the basidiomata of Thelephora sp. (Thelephoraceae) was examined, as well as some aspects of its ecology and habitat, using 24 specimens collected in the tropical forests of the Chamela Biological Station, Jalisco, Mexico. Our observations showed that this taxon has clavarioid basidiomata that can become resupinate during development and growth if they are in contact with rocks, litter or live plants, establishing in the latter only an epiphytic relationship. This tropical species may form groups of up to 139 basidiomata over an area of 32.2m2, and in both types of vegetation (tropical sub-evergreen and deciduous forest) were primarily located on steep (>20∼) South-facing slopes. It is found under closed canopy in both tropical forests, but its presence in sub-evergreen forests is greater than expected. La plasticidad fenot赤pica en hongos macrosc車picos ha sido poco estudiada en comparaci車n con la de plantas o animales y solo se conocen aspectos generales de estos cambios. En este trabajo se examin車 la variaci車n fenot赤pica en los basidiomas de una especie de Thelephora sp. (Thelephoraceae), as赤 como algunos aspectos de su ecolog赤a y h芍bitat a partir del estudio de 24 ejemplares recolectados en bosques tropicales de la Estaci車n de Biolog赤a de Chamela, Jalisco, M谷xico. Nuestras observaciones mostraron que este taxon presenta basidiomas en forma clavarioide, los cuales pueden modificarse a resupinados si en su proceso de desarrollo se interponen obstrucciones f赤sicas como rocas, restos vegetales o plantas vivas, estableciendo en estas 迆ltimas solo una relaci車n epif赤tica. Esta especie llega a formar conjuntos de hasta 139 basidiomas en un 芍rea de 32.2m2; con localizaci車n predominante en laderas orientadas hacia el sur, de pendientes mayores a 20∼, bajo doseles cerrados y con presencia mucho m芍s significativa de lo esperado en el bosque tropical subperennifolio. %K Thelephora %K basidioma %K plasticidad fenot赤pica %K bosque tropical %K Thelephora %K basidiome %K phenotypic plasticity %K tropical forest %U http://www.scielo.sa.cr/scielo.php?script=sci_arttext&pid=S0034-77442013000100029
