Se presenta la dinamica temporal de conidioforos de Zygosporium Mont. recolectados con una metodologia volumetrica no viable en la atmosfera de La Habana, durante el ano 2015. El muestreo sistematico se realizo con un captador volumetrico tipo Hirst (Lanzoni VPPS 2000). Se analizo el comportamiento anual e intradiario de Zygosporium en el aire, su densidad relativa (DR) y frecuencia relativa (FR), asi como la relacion entre la concentracion y las variables meteorologicas. Se detectaron conidioforos vesiculares y setosos de Zygosporium con una DR=0,007% y FR=3,16%, por lo que este genero puede clasificarse como raro en la atmosfera de La Habana. La concentracion diaria mostro correlacion positiva con la temperatura maxima diaria y negativa con la precipitacion del dia anterior, y los mayores valores de FR y DR se detectaron durante la estacion poco lluviosa. Ello evidencia que la aparicion de estas estructuras conidiogenas en el aire esta relacionada con condiciones de sequedad ambiental. Palabras claves : aeromicobiota, aeromicologia, atmosfera, registro Abstract It is presented the temporal dynamics of Zygosporium Mont. conidiophores, collected with a non-viable volumetric methodology in the atmosphere of Havana during 2015. Systematic sampling was performed with a volumetric sampler type Hirst (Lanzoni VPPS 2000). Annual and intra-day behavior, the relative density (DR) and relative frequency (FR), as well as the relationship of the concentration with the different meteorological variables were analyzed. Vesicular and setose conidiophores of Zygosporium were detected with DR = 0,007% and FR = 3,16%, so the genus can be classified as rare in the atmosphere of Havana. Daily concentrations correlated positively with the maximum daily temperature and negatively with precipitation of the previous day, and the highest values of FR and DR were obtained during the dry season, showing that the appearance of these conidiogenous structures in the air is related with conditions of environmental dryness.

Se informa la presencia de tres especies del genero Stachybotrys ( S. echinatus , S. chartarum y S. nephrospora ) en el aire de la zona occidental de Cuba, que se aislaron entre el 2007 – 2018 y se identificaron segun sus caracteristicas morfologicas distintivas. El resultado contribuye al conocimiento de la diversidad de la aeromicobiota en Cuba. Palabras claves : aeromicobiota, atmosfera, diversidad, hongos ABSTRACT The presence of three species of the Stachybotrys genus ( S. echinatus , S. chartarum and S. nephrospora ) is reported in the air of the western Cuba, which were isolated between 2007 – 2018 and were identified according to their distinctive morphological characteristics. The result contributes to the knowledge of the airborne fungi diversity in Cuba. Key words : aeromycobiota, atmosphere, diversity, fungi PDF
