Two new species of Ramichloridium-like hyphomycetes from senescent leaves of Night-scented Lily (Alocasia odora) in Taiwan

Abstract

Two new species of dematiaceous hyphomycetes isolated from senescent leaves of Night-scented Lily, Alocasia odora (plant family: Araceae) are described based on light and scanning electron microscopy as well as LSU rDNA sequence analysis. One of these species observed directly on the leaves and in vitro is placed in genus Parastenella because of morphological characteristics. The other species characterized in vitro only is accommodated in the genus Ramichloridium. Molecular data indicate a close relationship of both species with Ramichloridium musae within the Mycosphaerellaceae (Capnodiales, Dothideomycetidae, Dothideomycetes).

Periconiella species (anamorphic Mycosphaerellaceae) from Taiwan

“…The general topology of relevant taxa within the Mycosphaerellaceae, Capnodiales, elaborated in detail by Arzanlou et al (2007) and Crous et al (2009) and also shown by Kirschner and Chen (2010) has been confirmed. As these analyses show, several anamorph genera appear polyphyletic.…”

First record of Erysiphe magnifica on lotus, a host outside the Magnoliales

“…Certain microorganisms appear, however, to have evolved a general counter strategy in order to survive on such leaves independent of different degrees of self-cleaning of the host plants (Schreiber et al 2004). Other strongly water-repellent surfaces, such as the lower leaf surfaces of Alocasia species (Cerman 2007), have been reported as specific habitats of fungi other than Erysiphales (Kirschner and Chen 2010).…”
