New species of Kellermania, Piptarthron, Planistroma, and Planistromella from members of the Agavaceae

TL;DRAbstract

Five new fungal species from hosts in the Agavaceae are described.Kellermania nolinifoliorum and Planistroma nolinae and its anamorph, Piptarthron crassisporum are from Nolina sp., Piptarthron dasylirionis is found on Dasylirion sp., and Planistromella torsifoliorum, the teleomorph of Kellermania uniseptata (=Alpakesa uniseptata), is from Yucca rupicola.INTRODUCTION: Piptarthron and Kellermania are coelomycete genera with dark-brown to black, thick-walled, immersed, ostiolate conidiomata, holoblastic, determinate conidiogenous cells that each form a single acrogenous, large, hyaline, thin-walled conidium which lacks appendages in Piptarthron and bears appendages in Kellermania.The species of Piptarthron are separated by the size, shape, and septation of the conidia, and the number of locules in the.conidiomata (3).The species of Kellermania are separated by the number of septa in the conidia, and the size and number of apical appendages (2, 5).The separation of the two genera on the ba
