Presencia de Lophodermium australe en Pinus maestrensis
Main Article Content
Abstract
Lophodermium australe Dearness (Phacidiales: Hypodermataceae) se informa como especie nueva en la flora micológica cubana, que tiene como hospedero a Pinus maestrensis Bisse en la localidad «La Choricera» de la Sierra Maestra. A través del estudio estereoscópico y microscópico de las acículas de P. maestrensis Bisse, se encontraron cuerpos fructíferos con diferentes grados de desarrollo, y se observó el estado teleomórfico y anamórfico del hongo. Las características morfométricas de los ascocarpos, ascos, ascósporas y conidios se corresponden con las descritas por Minter y Millar para esta especie. Dada la importancia que tienen los pinos en el desarrollo forestal del país, por los antecedentes internacionales que informan especies del género Lophodermium Chev. como responsables de daños considerables, y por su alta frecuencia de aparición en plantaciones de Cuba, se determinó la especie y se analizó su posible relación con las condiciones edáficas del lugar.
