Catenulifera, typified by C. rhodogena (=Scopulariopsis rhodogena), was established to accommodate the anamorphs of Hyphodiscus (Ascomycota, Helotiales) and to delimit these taxa from members of Phialophora section Catenulatae. Catenulifera rhodogena has been inferred as monophyletic, but its relationship to ascomycetes with poorly differentiated phialidic(More)
The systematics of the ascomycete genera Apiorhynchostoma, Endoxyla and Pseudovalsaria are reevaluated based on the comparison of cultural characteristics, teleomorph morphology and DNA sequence data. Analyses of sequences of the internal transcribed spacer (ITS) of the ribosomal DNA operon and the large subunit (LSU) of the nuclear ribosomal DNA gene(More)
The aqueous extract of the stem bark of Tetrapleura tetraptera Schum et Thonn., Guibourtia ehie Leonard and the root extract of Taverniera abyssinica A. Rich. were used for the treatment of gastrointestinal related clinical problems in African ethnomedicine. HCl/EtOH-induced ulceration was used in fasted rat stomach to investigate the anti-ulcerative(More)
Xerombrophila, a new member of the Helotiales, is erected for a previously undescribed species that macroscopically resembles genera such as Phaeohelotium or Pezicula. The new species, for which we propose the name X. crystallifera, is characterized by a strong gelatinization of the medullary excipulum as well as the covering layer of the ectal excipulum,(More)
Baudoinia was described to accommodate a single species, B. compniacensis. Known as the 'whiskey fungus', this species is the predominant member of a ubiquitous microbial community known colloquially as 'warehouse staining' that develops on outdoor surfaces subject to periodic exposure to ethanolic vapours near distilleries and bakeries. Here we examine 19(More)
A room temperature aqueous extract of the roots of Taverniera abyssinica antagonized the contractile responses of the guinea-pig ileum to acetylcholine and histamine. The extract also relaxed the smooth muscle of the rabbit duodenum, abolished the pendular contractions and antagonized the effects of acetylcholine and histamine on this tissue. The results(More)
During a study of the microfungi on decaying leaves collected in México we encountered a fungus sharing features of the anamorph genera Heliocephala and Holubovaniella. This hyphomycete resembled Hol. elegans in possessing obclavate to fusiform, three-septate, rostrate phragmoconidia, but it can be distinguished by its much shorter, branched, determinate(More)
Colipila, a new member of the Helotiales, is erected for two previously undescribed lignicolous species resembling Dasyscyphella and Lachnum by macroscopy. Species of Colipila are characterized by their long, entirely smooth, hyaline, thin-walled, multiseptate, subulate to basally fusoid hairs that tend to be curved on the stipe and lower flanks, and(More)
