Publication Placement of the genus Angelina within Rhytismatales and observations of Angelina rufescens(Mycological Society of America, 2014) Karakehian, Jason; Lobuglio, Katherine; Pfister, DonaldAngelina rufescens is placed within the core clade of Rhytismatales (Leotiomycetes, Pezizomycotina, Ascomycota) based on analysis of LSU and mtSSU rDNA. The only species in the genus, it produces distinctive ascomata that reoccur annually on wood and on the remains of its own previous fructifications, forming dense conglomerations of interlocking longitudinally elongated apothecia with gray hymenia. Known collections and references of A. rufescens indicate that it is endemic to eastern and central United States. Morphological and cultural characters are described with notes on ascomata development. No mitospores were observed in field collections or in culture. Lectotypes are designated for Hysterium rufescens and its synonym Ascobolus conglomeratus. Angelina rufescens is illustrated here for the first time in the taxonomic literature.Publication Clarification of Peziza fimeti with notes on P. varia collections on dung(Mycotaxon, Ltd., 2013) Medardi, Gianfranco; Lantieri, Angela; Pfister, Donald; Lobuglio, Katherine; Cacialli, GabrieleThe smooth-spored species inhabiting dung, mainly of the Peziza fimeti group, were studied morphologically and through ITS sequence comparison. The results established that Peziza varia is also able to fruit on dung, clarifying a long-standing situation regarding two conflicting interpretations given in P. fimeti literature.Publication Placement of Medeolaria farlowii in the Leotiomycetes, and comments on sampling within the class(Springer Science + Business Media, 2009) Lobuglio, Katherine; Pfister, DonaldMedeolaria farlowii, an ascomycetous parasite of Medeola virginiana, has been included as the only member of the family Medeolariaceae and order Medeolariales. Its assignment within the Ascomycota has been problematic due to the lack of distinctive ascomatal form and ascus morphology. Asci are formed in a loosely organized hymenium on hypertrophic portions of Medeola virginiana stems. Phylogenetic analyses of nuclear 5.8S, large subunit, and small subunit rDNA gene sequences place M. farlowii in the Leotiomycetes with parsimony, Bayesian, and maximum likelihood analyses, but its position within this class remains unresolved. In general, limited taxon and gene sampling in the Leotiomycetes hampers placement of taxa within this class. A survey of available sequence data in the Leotiomycetes is given, and the implication for phylogenetic studies within the class is discussed. Medeolaria farlowii should be treated as a monotypic genus in the monotypic order Medeolariales, class Leotiomycetes.Publication Morphological and molecular study of Peziza emileia and P. howsei, two distinct taxa(Springer Science + Business Media, 2014) Medardi, Gianfranco; Lobuglio, Katherine; Pfister, Donald; Lantieri, AngelaPeziza emileia Cooke and P. howsei Roze & Boud. are compared here; they are morphologically very similar, but the internal transcribed spacer (ITS) sequence is unique for each of the two species. Furthermore, since the holotype of P. emileia deposited in Kew (K) contains an unidentified fungus and the holotype of P. howsei in Paris (PC) no longer exists, we provide lectotypification and epitypification for both taxa.Publication The Genus Strobiloscypha: A New Species And An Unresolved Phylogenetic Placement(Mycological Society of Montenegro and Montenegrin Mycological Center, 2013) Peric, Branislav; Lobuglio, Katherine; Pfister, DonaldA new species of the genus Strobiloscypha, S. cupressina, is described from collections made in Montenegro. This species, like the other species in the genus, S. keliae, occurs on rotting leaves and cones of Cupressaceae. The genus had been assigned to the Sarcosomataceae but molecular phylogenetic analysis shows that it falls outside that family with no resolved placement elsewhere. Morphologically it is perhaps most close to the Chorioactidaceae.Publication Systemic Infection of Medeola virginiana (Liliaceae) by the Fungus Medeolaria farlowii (Ascomycota: Leotiomycetes)(Institute of Microbiology, Academia Sinica, 2013) Lobuglio, Katherine; Pfister, DonaldPrimers were designed to specifically amplify ITS rDNA regions of the fungus Medeolaria farlowii. The fungus was shown to be present not only in stem lesions but in apparently uninfected leaves, stems and rhizomes of the host plant, Medeola virginiana. Since the plant reproduces clonally it is likely that the infection is carried in populations of the host plant through systemic infection of vegetative plant parts. The growth patterns of the plant are reviewed and examples are given of long-term perpetuation of the fungus in populations of the plant.
