Novel <I>Phaeoacremonium</I>
Persoonia 20, 2008: 87–102 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158508X324227 Novel Phaeoacremonium species associated with necrotic wood of Prunus trees U. Damm1,2, L. Mostert1, P.W. Crous1,2, P.H. Fourie1,3 Key words Abstract The genus Phaeoacremonium is associated with opportunistic human infections, as well as stunted growth and die-back of various woody hosts, especially grapevines. In this study, Phaeoacremonium species were Diaporthales isolated from necrotic woody tissue of Prunus spp. (plum, peach, nectarine and apricot) from different stone fruit molecular systematics growing areas in South Africa. Morphological and cultural characteristics as well as DNA sequence data (5.8S pathogenicity rDNA, ITS1, ITS2, -tubulin, actin and 18S rDNA) were used to identify known, and describe novel species. From Togninia β the total number of wood samples collected (257), 42 Phaeoacremonium isolates were obtained, from which 14 Togniniaceae species were identified. Phaeoacremonium scolyti was most frequently isolated, and present on all Prunus species sampled, followed by Togninia minima (anamorph: Pm. aleophilum) and Pm. australiense. Almost all taxa isolated represent new records on Prunus. Furthermore, Pm. australiense, Pm. iranianum, T. fraxinopennsylvanica and Pm. griseorubrum represent new records for South Africa, while Pm. griseorubrum, hitherto only known from humans, is newly reported from a plant host. Five species are newly described, two of which produce a Togninia sexual state. Togninia africana, T. griseo-olivacea and Pm. pallidum are newly described from Prunus armeniaca, while Pm. prunicolum and Pm. fuscum are described from Prunus salicina.

Taxonomy and Pathology of Togninia (Diaporthales) and Its Phaeoacremonium Anamorphs
STUDIES IN MYCOLOGY 54: 1–113. 2006. Taxonomy and Pathology of Togninia (Diaporthales) and its Phaeoacremonium Anamorphs Lizel Mostert1,2, Johannes Z. Groenewald1, Richard C. Summerbell1, Walter Gams1 and Pedro W. Crous1 1Centraalbureau voor Schimmelcultures, P.O. Box 85167, 3508 AD Utrecht, The Netherlands; 2Current address: Department of Plant Pathology, University of Stellenbosch, Private Bag X1, Stellenbosch 7602, South Africa *Correspondence: Lizel Mostert, [email protected] Abstract: The genus Togninia (Diaporthales, Togniniaceae) is here monographed along with its Phaeoacremonium (Pm.) anamorphs. Ten species of Togninia and 22 species of Phaeoacremonium are treated. Several new species of Togninia (T.) are described, namely T. argentinensis (anamorph Pm. argentinense), T. austroafricana (anamorph Pm. austroafricanum), T. krajdenii, T. parasitica, T. rubrigena and T. viticola. New species of Phaeoacremonium include Pm. novae-zealandiae (teleomorph T. novae-zealandiae), Pm. iranianum, Pm. sphinctrophorum and Pm. theobromatis. Species can be identified based on their cultural and morphological characters, supported by DNA data derived from partial sequences of the actin and β-tubulin genes. Phylogenies of the SSU and LSU rRNA genes were used to determine whether Togninia has more affinity with the Calosphaeriales or the Diaporthales. The results confirmed that Togninia had a higher affinity to the Diaporthales than the Calosphaeriales. Examination of type specimens revealed that T. cornicola, T. vasculosa, T. rhododendri, T. minima var. timidula and T. villosa, were not members of Togninia. The new combinations Calosphaeria cornicola, Calosphaeria rhododendri, Calosphaeria transversa, Calosphaeria tumidula, Calosphaeria vasculosa and Jattaea villosa are proposed. Species of Phaeoacremonium are known vascular plant pathogens causing wilting and dieback of woody plants. -

Réblová1* and K.A. Seifert2 1Department of Taxonomy, Institute of Botany of the Academy of Sciences, CZ – 252 43, Průhonice, Czech Republic; 2Biodiversity (Mycology and Botany), Agriculture and Agri- Food Canada, Ottawa, Ontario, K1A 0C6, Canada *Correspondence: Martina Réblová, [email protected] Abstract: Sterigmatobotrys macrocarpa is a conspicuous, lignicolous, dematiaceous hyphomycete with macronematous, penicillate conidiophores with branches or metulae arising from the apex of the stipe, terminating with cylindrical, elongated conidiogenous cells producing conidia in a holoblastic manner. The discovery of its teleomorph is documented here based on perithecial ascomata associated with fertile conidiophores of S. macrocarpa on a specimen collected in the Czech Republic; an identical anamorph developed from ascospores isolated in axenic culture. The teleomorph is morphologically similar to species of the genera Carpoligna and Chaetosphaeria, especially in its nonstromatic perithecia, hyaline, cylindrical to fusiform ascospores, unitunicate asci with a distinct apical annulus, and tapering paraphyses. Identical perithecia were later observed on a herbarium specimen of S. macrocarpa originating in New Zealand. Sterigmatobotrys includes two species, S. macrocarpa, a taxonomic synonym of the type species, S. elata, and S. uniseptata. Because no teleomorph was described in the protologue of Sterigmatobotrys, we apply Article 59.7 of the International Code of Botanical Nomenclature. We epitypify (teleotypify) both Sterigmatobotrys elata and S. macrocarpa to give the genus holomorphic status, and the name S. -

Pleurostomophora, an Anamorph of Pleurostoma (Calosphaeriales), a New Anamorph Genus Morphologically Similar to Phialophora

The close relationship among these three species was confirmed on the basis of sequence analysis of the 5.8S nuclear ribosomal RNA gene and its flanking internal transcribed spacers (ITS1 and ITS2). Furthermore, molecular data from partial 18S small subunit (SSU) DNA, revealed these three species were not phylogenetically closely related to the type of Phialophora, Ph. verrucosa, which was nested in the Chaetothyriales clade. A new anamorph genus, Pleurostomophora (P.), was therefore proposed to accom- modate these species. The formation of perithecia from single-ascospore isolates of Pleurostoma (Pl.) ootheca also showed it to have a homothallic mating system. Taxonomic novelties: Pleurostomophora D. Vijaykrishna, L.

Discovered and Re- Evaluation of Pleurophragmium
Fungal Diversity Teleomorph of Rhodoveronaea (Sordariomycetidae) discovered and re- evaluation of Pleurophragmium 1* Martina Réblová 1Department of Plant Taxonomy, Institute of Botany, Academy of Sciences, CZ-252 43 Průhonice, Czech Republic Réblová, M. (2009). Teleomorph of Rhodoveronaea (Sordariomycetidae) discovered and re-evolution of Pleurophragmium. Fungal Diversity 36: 129-139. An undescribed teleomorph was discovered for Rhodoveronaea (Sordariomycetidae), a previously known anamorph genus with the single species R. varioseptata characterized by pigmented, septate conidia and holoblastic-denticulate conidiogenesis. The teleomorph is a lignicolous perithecial ascomycete with nonstromatic, dark perithecia, consisting of a globose immersed venter and stout conical emerging neck; cylindrical long-stipitate asci, nonamyloid apical annulus and fusiform, septate, hyaline ascospores. The fertile conidiophores of R. varioseptata were associated with the perithecia on the natural substratum and they were also obtained in vitro. Because no teleomorph was designated in the protologue of Rhodoveronaea, the new Article 59.7 of the International Code of Botanical Nomenclature is applied in this case and Rhodoveronaea is expanded to holomorphic application by teleomorphic epitypification of the type species R. varioseptata. The name R. varioseptata is fully adopted for the discovered teleomorph. On the basis of detailed morphology, cultivation studies and phylogenetic analyses of ncLSU rDNA sequences, Rhodoveronaea is segregated from the morphologically similar genera Lentomitella and Ceratosphaeria; its relationship with Ceratosphaeria fragilis and C. rhenana is discussed. The relationship of Rhodoveronaea with the morphologically similar Dactylaria parvispora is investigated using morphological features and molecular sequence data. Phylogenetic findings based on ncLSU rDNA sequence data indicate that Dactylaria is polyphyletic. The genus Pleurophragmium is excluded from the synonymy of Dactylaria and is re-evaluated for P. -

A Fissitunicate Ascus Mechanism in the Calosphaeriaceae, and Novel Species of Jattaea and Calosphaeria on Prunus Wood
Persoonia 20, 2008: 39–52 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158508X313940 A fissitunicate ascus mechanism in the Calosphaeriaceae, and novel species of Jattaea and Calosphaeria on Prunus wood U. Damm1, P.W. Crous1,2, P.H. Fourie1,3 Key words Abstract During a survey of Prunus wood from South Africa, isolations were made of three presumably Calosphaeri- alean fungi that formed hyphomycetous, phialidic anamorphs in culture. In order to reveal the phylogenetic relation- apical ring ship of these fungi, they were characterised on a morphological and molecular (LSU and ITS rDNA) basis. Two ascospore discharge isolates that formed a teleomorph in culture are newly described as Calosphaeria africana sp. nov. Although asci of ascus dehiscence Calosphaeria are characterised by having non-amyloid apical rings, two functional wall layers were observed in asci beta-tubulin of C. africana, which has hitherto not been observed in any member of the Calosphaeriaceae. However, Calosphaer- Calosphaeria iaceae (Calosphaeriales, Sordariomycetes) are not closely related to other bitunicate fungi like Dothideomycetes, Calosphaeriaceae Chaetothyriales and bitunicate lichens. Possession of two separating wall layers is considered to be a result of both ITS inherited abilities and convergent evolution under a strong selection pressure of the environmental conditions that Jattaea favour an extension of the ascus. The other two species represented a separate lineage within Calosphaeriaceae, LSU and formed phialophora-like anamorphs. By obtaining the teleomorph in culture, one of them could be identified Phialophora as a species of Jattaea, described here as Jattaea prunicola sp. nov., while the second, which only produced the Prunus anamorph, is named as Jattaea mookgoponga sp. -
