Resumen

Se describe Cortinarius watsoneae, especie nueva del subgénero Myxacium, sección Myxacium, encontrada en bosques mixtos de pino en los estados del Golfo de Norte América. Las setas se caracterizan por los colores griseo violáceo a violeta de las láminas juveniles y por sus basidiosporas relativamente grandes en comparación con las de C. mucosus. La secuencia ITS es 97% similar a aquellas de las especies más cercanas dentro de la sección Myxacium que son C. collinitus y C. mucosus. El nombre para esta especie nueva es en honor a Geraldine Watson.
