Abstract Several interesting Ustilaginaceae yeast morphs were isolated during ongoing surveys of phylloplane-associated fungi in Louisiana (USA) and Guyana. Here we describe Farysia magdalena sp. nov., a phylloplane yeast isolated in southern Louisiana, based on phylogenetic analyses, assimilation profiles and morphological characters, and discuss the yeast morphs in this genus. Additionally, we describe the anamorphic stage of Anthracocystis heteropogonicola, isolated from plant phylloplanes from the Americas. This is the first report of this fungus in the Western Hemisphere and the first description of the yeast morph for a species of Anthracocystis. Keywords Dimorphic fungi . Farysia thuemenii .

Introduction The phylloplane is rich in microbes including fungi and yeasts. Many anamorphic basidiomycete yeast species belonging to disparate genera in Agaricostilbomycetes, Cystobasidiomycetes, Exobasidiomycetes, Microbotryomycetes (Pucciniomycotina), Tremellomycetes (Agaricomycotina), and Ustilaginomycetes (Ustilaginomycotina), are commonly isolated from plant leaves (e.g., Swann and Taylor 1995; Kurtzman et al. 2011; Albu 2012; Begerow et al. 2014; He et al. 2019). The last of these, Tomás Allen Rush and Sebastian Albu contributed equally to this work. Section Editor: Dominik Begerow * Tomás Allen Rush [email protected] * M. Catherine Aime [email protected] 1

Ustilaginomycetes, contains numerous dimorphic fungi that, in addition to a saprobic anamorphic yeast haplophase, also have a plant pathogenic dikaryophase (e.g., Sugita et al. 2003; Stoll et al. 2005; Begerow et al. 2006, 2014; Riess et al. 2016; Kijpornyongpan et al. 2018). Ustilaginomycetes are divided into four orders, Uleiellales, Urocystidales, Ustilaginales, and Violaceomycetales, of which Ustilaginales contain some of the best characterized of these, including classic exemplars of the syndromic group known as “smut fungi”—obligate plant pathogens that produce characteristic darkly pigmented teliospores (e.g., Stoll et al. 2005; Begerow et al. 1997, 2000, 2006, 2014; Albu et al. 2015; Riess et al. 2016; Kijpornyongpan et al. 2018).
