Abstract:
During a survey of culturable microfungi from the bark of sugar maple (Acer saccharum), Atrocalyx glutinosus and Nigrograna rubescens, two novel species of Pleosporales (Dothideomycetes) were isolated from several locations in eastern Ontario, Canada. Formal species descriptions are presented based on unique colony phenotypes and micromorphological characteristics and supported using multi-locus molecular phylogenetic comparisons with similar species. Both A. glutinosus and N. rubescens produce pycnidial asexual morphs in culture. As their names imply, under specific culture conditions, A. glutinosus excretes large amounts of the glutinous polysaccharide pullulan and N. rubescens produces a dark red naphthoquinone pigment that diffuses in the culture medium.

摘要:
在一项来自糖枫(Acersaccharum)树皮的可培养微真菌的调查中,谷黄花萼和芥子,从安大略省东部的几个地方分离出了两种新的侧孢菌(Dothideomcetes),加拿大。正式物种描述是根据独特的菌落表型和微形态特征提出的,并使用与相似物种的多位点分子系统发育比较来支持。谷氨酸曲霉和冬凌草均在培养中产生比氏无性形态。正如他们的名字所暗示的,在特定的培养条件下,A.glutinosus分泌大量的糯性多糖普鲁兰和冬凌草产生深红色萘醌色素,在培养基中扩散。引文:MackJN,SprouleA,防护罩SW,SeifertKA,史密斯M,OveryDP(2024)。两种新的从宏碁树皮中分离出的侧孢菌。真菌系统学和进化13:1-14。doi:10.3114/fuse.2024.13.01。
