Fungi associated with dead branches of Magnolia grandiflora: A case study from Qujing, China

Abstract

As a result of an ongoing survey of microfungi associated with garden and ornamental plants in Qijing, Yunnan, China, several saprobic fungal taxa were isolated from <i>Magnolia grandiflora</i>. Both morphological and combined SSU, LSU, ITS, <i>tef1</i>, and <i>rpb2</i> locus phylogenetic analyses (maximum-likelihood and Bayesian analyses) were carried out to identify the fungal taxa. Three new species are introduced in <i>Pleosporales, viz</i>., <i>Lonicericola qujingensis</i> (<i>Parabambusicolaceae</i>), <i>Phragmocamarosporium magnoliae</i>, and <i>Periacma qujingensis</i> (<i>Lentitheciaceae</i>). <i>Botryosphaeria dothidea, Diplodia mutila</i>, and <i>Diplodia seriata</i> (in <i>Botryosphaeriaceae</i>) are reported from <i>Magnolia grandiflora</i> for the first time in China. <i>Angustimassarina populi</i> (<i>Amorosiaceae</i>) is reported for the first time on <i>M. grandiflora</i> from China, and this is the first report of a member of this genus outside Europe. <i>Shearia formosa</i> is also reported for the first time on <i>M. grandiflora</i> from China.
