Pyrenomycetes of the great smoky mountains national park v annulohypoxylon and hypoxylon xylariaceae
Fungal Diversity, 2007Co-Authors: Larissa N. Vasilyeva, Jack D Rogers, Andrew N. MillerAbstract:As part of an inventory of the Pyrenomycetes of the Great Smoky Mountains National Park (GSMNP) (Vasilyeva and Stephenson, 2004, 2005, 2006; Vasilyeva et al., 2007), specimens of Annulohypoxylon Y.-M. Ju, J.D. Rogers & H.-M. Hsieh and Hypoxylon Bull. were collected throughout the park from late March to early May 2002, and in different periods in 2004-2006. These specimens are deposited in BPI, ILLS, WSP and VLA (the Institute of Biology and Soil Science, Vladivostok, Russia). Collectors are abbreviated as follows: ANM, Andrew N. Miller; JDR, Jack D. Rogers; and LNV, Larissa N. Vasilyeva. Images and an interactive key to most species can be found at: http://mycology.sinica.edu.tw/Xylariaceae. Prior to the study reported herein, eight species were recorded from the GSMNP under the generic name Hypoxylon (Petersen, 1979). Most of them have been collected in the Park recently. However, some fungi previously identified as Hypoxylon have been instated in different genera. Only two

algunas especies de hypoxylon Pyrenomycetes xylariaceae de mexico
Acta Botanica Mexicana, 1999Co-Authors: Felipe San Martin, Y M Ju, Jack D RogersAbstract:An artificial key to 41 species and 3 varieties of the genus Hypoxylon sensu stricto collected in Mexico so far, is presented; 31 species and one variety belong to section Hypoxylon whereas 10 species and 2 varieties correspond to section Annulata . Two taxa remain without specific epithet due the scarcity of the material or the lack of anamorphic data. The new variety Hypoxylon shearii var. minor is proposed. Data on distribution, substrates, collecting dates, and affinities with other species of the genus, are provided for most taxa.

pareutypella gen nov for two long ostiolate Pyrenomycetes from taiwan
Mycologia, 1995Co-Authors: Jack D RogersAbstract:Pareutypella is described as a new genus with two species P. sulcata and P. nematoceras. They have elongated ostioles, allantoid ascospores, sessile asci that detach at maturity from the ascogenous system, and hyphomycetous anamorphs with holoblastic conidi? ogenesis. The taxonomic affinities of these fungi are discussed.

The occurrence of Pyrenomycetes, Loculoascomycetes and their anamorphs in the plant communities of Babia Góra
Polish Botanical Society, 2014Co-Authors: Andrzej ChlebickiAbstract:This paper includes a descriptions of fungi belonging to Pyrenomycetes, Loculoascomycetes,Coelomycetes and Hyphomycetes which were found on Mt. Babia Góra in the years 1983 -1988. Also presented ara comparative studies of thę mycoflora of the selected trees and comparative studies of the vertical ranges of fungi and vascular plants. The investigations show that Pyrenomycetes fungi depend on the plant communities in which they occur

Some mycogenous fungi from Poland
Polish Botanical Society, 2014Co-Authors: Andrzej Chlebicki, Alina SkirgiełłoAbstract:In the present paper the results of earlier studies on mycogenous fungi which were gathered occasionally are summarized. Fifieen specres. previously Pyrenomycetes s.l., have been found growing on other fungi Immothia hypoxylon and Lophiostoma polyporicola are new species to the Polish mycoflora. Sphaeronaemella Kulczyńskiana described by K. R o u p p e r t (1912) is considered to be Eleuteromyces subultus. Relatively high number of fungi inhabiting stromata of Diatrypella favacea is probably connected with its early colonization of the Polish area

convergence in ascospore discharge mechanism among pyrenomycete fungi based on 18s ribosomal rna gene sequence
Molecular Phylogenetics and Evolution, 1992Co-Authors: Mary L Berbee, John W TaylorAbstract:Fungi of the class Pyrenomycetes (Ascomycotina) form a morphological series ranging from those that shoot ascospores (sexual spores) forcibly from the ascus (spore sac) to fungi that ooze ascospores or have no obvious mechanism for ascospore release. Did forcible ascospore discharge evolve within these Pyrenomycetes, or has it been lost in the group? We determined the sequences of the 18S ribosomal RNA gene from three fungi and used these, along with six sequences from our previous work and three sequences from Gen-Bank, to infer the phylogeny of 12 ascomycetes with various ascospore discharge mechanisms. The 1720 base pairs of sequence data per fungus yielded 361 variable sites, 198 phylogenetically informative sites, and a single most parsimonious tree requiring 562 nucleotide changes. The tree shows that the capacity to shoot ascospores into the air has been lost or, less probably, gained repeatedly and independently. Species lacking forcible ascospore discharge are intercalated among three lineages of species with forcible discharge. In this tree, seven of the nine internal branches appeared in 95% or more of 500 bootstrap replicates. A tree uniting the fungi with forcible ascospore discharge into a monophyletic group required 45 additional steps and fit significantly less well with the data than the most parsimonious tree, based on a maximum likelihood test. Two of the fungi whose sequence we determined, Pseudallescheria boydii and Sporothrix schenekii, are not closely related to one another, even though both are human pathogens and both are from pyrenomycete lineages lacking forcible ascospore discharge. Using the well-resolved, most parsimonious tree, we inferred base substitution patterns in the 18S rRNA. The transition-to-transversion ratio was 1.9. Of all 12 possible substitutions, 29% were from U to C. At sites corresponding to yeast stem positions, A to G transitions were frequent, perhaps compensating for some of the U to C changes, and maintaining secondary structure base pairing (A to G: U to C = 3:4). In loop or bulge positions without secondary structure base pairing, U to C transitions were still frequent, but A to G transitions were rare (A to G: U to C = 1: 5).
