Annulohypoxylon (Hypoxylaceae) species from Argentina Darwiniana
Sir,Esteban B; Kuhnert,Eric; HladkiI,Adriana I; Romero,Andrea I.
Eleven Annulohypoxylon species are recognized for Argentina. Annulohypoxylon purpureonitens and A. purpureopigmentum are recorded for the first time in the Southern Cone, while A. stygium and A. nitens represent new reports for Northwestern Argentina. Furthermore, the asexual states of A. purpureopigmentum and A. subeffusum are described for the first time. In addition, a comparative table, a key to the Argentinean species, photographs, and a distributional map of these species in South America are provided.

Cannonia australis: Ascomycota, Xylariaceae) found in equatorial Brazil Darwiniana
Trierveiler-Pereira,Larissa; Agra,Leandro A. N. N.; Capdet,Mariana; Romero,Andrea I..
Cannonia is a xylarioid genus originally described from the southern hemisphere (Argentina and Australia) growing on dead parts of palms. To date, the genus is considered monospecific and the only species recognized is C. australis. During collection trips in the State of Maranhão, Brazil, specimens of C. australis were gathered on the inflorescence rachis and floral pedicels of a Syagrus species (Arecaceae). Description and line drawings are provided, this being the first record from Brazil.

Etiología de la muerte descendente del mezquite (Prosopis laevigata L.) en la reserva de la biosfera del Valle de Zapotitlán, México Agrociencia
De La Torre-Almaráz,Rodolfo; Cota-Trujillo,F. Maribel; García-Rojas,J. Lilia; Campos,Jorge E.; San-Martín,Felipe.
En 2001, plantas de mezquite (Prosopis laevigata L.) con muerte descendente de ramas, fueron observadas en la reserva de la Biosfera de Tehuacán-Cuicatlán, Puebla (18° 15' N y 97° 25' O). Sobre las ramas con daños se desarrolló un hongo de color pardo claro que produjo conidióforos y conidios hialinos, verdosos, elipsoides con un extremo truncado. En el estroma pul vinado y aglomerado hubo masas de peritecios negros conspicuos y globosos. Las ascosporas son pardo-oscuro, unicelulares, elipsoides desiguales, con extremos redondeados y un tubo germinativo a lo largo de la espora. Las perisporas fueron dehiscentes en tratamiento con KOH (10 %) y la epispora lisa y enrollada. El hongo fue identificado como Hypoxylon diatrypeoides Rehm y su anamorfo como una...

Novedades para el género Rosellinia (Ascomycota-Xylariaceae) en el noroeste de la República Argentina Boletín de la Sociedad
Sir,Esteban B; Perera,Teresa C; Romero,Andrea I; Hladki,Adriana I.
Se reporta por primera vez a Rosellinia canzacotoana en el Cono Sur de América y a Rosellinia arcuata para la Argentina. Rosellinia necatrix se cita creciendo sobre árboles en descomposición de la flora autóctona de la Argentina. Se realiza una revisión de tres holotipos de Spegazzini: Rosellinia australis, Rosellinia bonaerensis, Rosellinia smilacina, detallando su estado nomenclatural y taxonómico actual. También se presenta una clave dicotómica de las especies con aspecto rosellinoide del Noroeste del país y un mapa de distribución.

Phylogenetic and taxonomic revision of Lopadostoma Naturalis
Jaklitsch, W.M.; Fournier, J.; Rogers, J.D.; Voglmayr, H..
The genus Lopadostoma (Xylariaceae, Xylariales) is revised. Most species formerly assigned to Lopadostoma do not belong to the genus. Twelve species are herein recognised, of which two are only known from morphology. Ten species, of which six (L. americanum, L. fagi, L. insulare, L. lechatii, L. meridionale and L. quercicola) are newly described, are characterised by both morphology and DNA phylogeny using LSU, ITS and rpb2 sequences. Morphologically, ecologically and phylogenetically Lopadostoma is a well-defined genus comprising exclusively species with pustular pseudostroma development in bark of angiospermous trees. Phaeosperma ailanthi, Phaeosperma dryophilum and Sphaeria linosperma are combined in Lopadostoma. Lopadostoma gastrinum is neotypified and...

Phylogeny of Discosia and Seimatosporium, and introduction of Adisciso and Immersidiscosia genera nova Naturalis
Tanaka, K.; Endo, M.; Hirayama, K.; Okane, I.; Hosoya, T.; Sato, T..
Discosia (teleomorph unknown) and Seimatosporium (teleomorph Discostroma) are saprobic or plant pathogenic, coelomycetous genera of so-called ‘pestalotioid fungi’ within the Amphisphaeriaceae (Xylariales). They share several morphological features and their generic circumscriptions appear unclear. We investigated the phylogenies of both genera on the basis of SSU, LSU and ITS nrDNA and β-tubulin gene sequences. Discosia was not monophyletic and was separated into two distinct lineages. Discosia eucalypti deviated from Discosia clade and was transferred to a new genus, Immersidiscosia, characterised by deeply immersed, pycnidioid conidiomata that are intraepidermal to subepidermal in origin, with a conidiomatal beak having periphyses. Subdividing Discosia...

Resolution of morphology-based taxonomic delusions: Acrocordiella, Basiseptospora, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria Naturalis
Jaklitsch, W.M.; Gardiennet, A.; Voglmayr, H..
Fresh material, type studies and molecular phylogeny were used to clarify phylogenetic relationships of the nine genera Acrocordiella, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria. At first sight, some of these genera do not seem to have much in common, but all were found to belong to the Xylariales, based on their generic types. Thus, the most peculiar finding is the phylogenetic affinity of the genera Acrocordiella, Requienella and Strickeria, which had been classified in the Dothideomycetes or Eurotiomycetes, to the Xylariales. Acrocordiella and Requienella are closely related but distinct genera of the Requienellaceae. Although their ascospores are similar to those of Lepteutypa,...

Taxonomic and phylogenetic re-evaluation of Microdochium, Monographella and Idriella Naturalis
Hernández-Restrepo, M.; Groenewald , J.Z.; Crous, P.W..
Based on morphology and DNA sequence data the taxonomic relationships of Microdochium, Monographella and Idriella were reassessed. Microdochium is morphologically and phylogenetically circumscribed, and the sexual genus Monographella treated as synonym on the basis that Microdochium has more species, is more commonly encountered, and more frequently used in literature. An epitype is designated for Microdochium phragmites, and several well-known species are redefined based on their morphology and DNA sequence data (LSU, ITS, BTUB and RPB2). Furthermore, the revision of Microdochium led to six new combinations (M. albescens, M. consociatum, M. fusariisporum, M. maydis, M. opuntiae and M. stevensonii) and six new species (M. citrinidiscum, M. colombiense, M....

The phylogenetic position of Rhopalostroma as inferred from a polythetic approach Naturalis
Stadler, M.; Fournier, J.; Gardt, S.; Peršoh, D..
The xylariaceous genus Rhopalostroma comprises a small conglomerate of stromatic, angiospermassociated pyrenomycetes, which have so far exclusively been reported from the palaeotropics, above all from tropical Africa and South Asia. Morphological and chemotaxonomic studies had suggested their close relationship to the genera Daldinia and Hypoxylon. However, those results were mainly based on herbarium specimens, and no molecular phylogenetic data were available on Rhopalostroma. During a foray in Côte d’Ivoire, fresh material of R. angolense was collected, cultured and studied by microscopic methods and by secondary metabolite profiling using high performance liquid chromatography coupled with diode array and mass spectrometric detection. In addition, ITS...
