Abstract:
The order Sordariales includes the polyphyletic family Lasiosphaeriaceae, which comprises approximately 30 genera characterized by its paraphysate ascomata, asci with apical apparati, and mostly two-celled ascospores, which have a dark apical cell and a hyaline lower cell, frequently ornamented with mucilaginous appendages. To produce a more natural classification of this family, we carried out a phylogenetic analysis based on sequences of the internal transcribed spacer region (ITS), the nuclear rDNA large subunit (LSU), and fragments of ribosomal polymerase II subunit 2 (rpb2) and β-tubulin (tub2) genes of several isolates from soil and of reference strains of the Sordariales. As a result, Lasiosphaeriaceae s. str. has been circumscribed for the clade including the type species of the genus Lasiosphaeria and, consequently, its description emended. In addition, the new families Diplogelasinosporaceae, Naviculisporaceae, and Schizotheciaceae are introduced to accommodate those taxa located far from the Lasiosphaeriaceae s. str. Moreover, we propose the erection of the new genera Areotheca, Lundqvistomyces, Naviculispora, Pseudoechria, Pseudoschizothecium, and Rhypophila based on morphological and sequence data. New combinations for several species of the genera Cladorrhinum, Jugulospora, Podospora, Schizothecium, and Triangularia are proposed, their descriptions are emended, and dichotomous keys are provided to discriminate among their species.

Abstract:
During research on the biological diversity of coprophagous Scarabaeoidea in the Polish Carpathians, a particular morphotype of epizoic fungus was found on several species of coprophages of the Onthophagus genus. The fungus occurs on the mesosternum and legs of the beetles. Detailed morphological observations and genetic analyses proved this epizoic fungus to be distinct from any other known species, it is new to science. It is very characteristic in terms of morphological features, as it grows in the form of thallus closely adhered to the insect exoskeleton with only the outermost layer of cells viable. The shape of thallus itself is determined by its location on insect’s body. Only vegetative structures and conidial reproduction were observed. In the presented study, we describe and establish this newly found morphotype in the rank of new monotypic genus and document its distinctness with eleven barcode sequences. Three gene based, LSU plus SSU plus ITS, phylogenetic positioning places the new genus firmly nested within Lasiosphaeriaceae (Sordariales) with Zygospermella insignis (Mouton) Cain as its closest relative. No epizoic colonization of dung beetles was described in Lasiosphaeriaceae to date nor Lasiosphaeriaceae species with similar morphology. The potential role of the described epizoic fungus in the living environment of the Onthophagus dung beetles is discussed.

Abstract:
Pseudohalonectria lignicola and five new species of Pseudohalonectria are described and illustrated from submerged wood in freshwater. Species are similar in overall morphology and produce bright yellow to brown perithecia, asci with thimble-shaped apical apparatuses and that separate from ascogenous hyphae at maturity, long, septate paraphyses attached to ascogenous hyphae, and hyaline to lightly pigmented phragmosporous ascospores. An anamorphic state was found for only one species. Pseudohalonectria has features common to both the Sordariales and Diaporthales, but is best placed in the Sordariales. Species are inhibitory to other filamentous fungi and yeasts in paired culture, and form soft-rot cavities in balsa and beech wood.

Abstract:
Investigations into the fungi occurring on wood submerged in freshwater ecosystems have revealed a unique, but characteristic group of fungi. In this paper a new pyrenomycete, Tamsiniella labiosa gen. et sp.nov., is described and illustrated with light, scanning, and transmission electron micrographs. The genus has remarkable short stipitate cylindrical asci with an internal refractive apical ring that are apically truncate and have an external thickening. Ascospores are ellipsoidal-fusiform and surrounded by a mucilaginous sheath. At the transmission electron microscope level, the annulus part of the ascus apical apparatus is differentiated from the inner ascus wall layer and is composed of horizontally oriented, electron-dense fibrillar material. A narrow plug is present in the centre of the apical ring. An electron-dense amorphous region occurs between the outer ascus wall layer and the annulus part of the apical apparatus. The outer ascus wall layer is lacking at the apex. The ultrastructure of the ascus apex differs from those described in the Lasiosphaeriaceae, Sordariaceae, and Xylariaceae.Key words: aquatic fungi, Myelosperma, new genus, transmission electron microscope.

Abstract:
Las relaciones de orquídeas-hongos han sido estudiadas principalmente en orquídeas terrestres. El trabajo aquí presentado trata sobre la diversidad y signifi cado biológico de los hongos asociados a la orquídea epifi ta endémica Laelia speciosa. Se registró la presencia fungal en semillas, protocormos y plántulas durante la germinación y primeros estadíos de desarrollo in vitro de L. speciosa mediante evidencia molecular. Las secuencias de ITS confi rmaron la presencia de hongos en raíces, cápsulas, semillas y también en plántulas cultivadas in vitro. Ninguno de los hongos encontrados formó pelotones característicos por lo que no se asume que sean hongos micorrízicos. Se identifi caron 18 taxa de hongos pertenecientes a ocho géneros (Alternaria, Curvularia, Cylindrocarpon, Fusarium, Myrmecridium, Neonectria, Penicillium y Tetracladium) y especies desconocidas de Atractiellales, Helotiales, Hypocreales, Lasiosphaeriaceae, Nectriaceae, Sordariomycetes y Tricholomataceae. De éstos, se infi rió la biología de nueve parásitos, cuatro saprobios y dos endófi tos. Uno de los hongos, perteneciente a una especie de Helotiales coloniza todos los tejidos de la orquídea, incluyendo semillas y plántulas cultivadas in vitro; por tanto, aun si todas las precauciones son tomadas, es difícil obtener “cultivos axénicos”de L. speciosa. Existe una considerable diversidad de hongos endófi tos dentro de los órganos de L. speciosa a través de todo su ciclo de vida.

Abstract:
Liming is an effective agricultural practice and is broadly used to ameliorate soil acidification in agricultural ecosystems. Our understanding of the impacts of lime application on the soil fungal community is scarce. In this study, we explored the responses of fungal communities to liming at two locations with decreasing soil pH in Oregon in the Pacific Northwest using high-throughput sequencing (Illumina MiSeq). Our results revealed that the location and liming did not significantly affect soil fungal diversity and richness, and the impact of soil depth on fungal diversity varied among locations. In contrast, location and soil depth had a strong effect on the structure and composition of soil fungal communities, whereas the impact of liming was much smaller, and location- and depth-dependent. Interestingly, families Lasiosphaeriaceae, Piskurozymaceae, and Sordariaceae predominated in the surface soil (0–7.5 cm) and were positively correlated with soil OM and aluminum, and negatively correlated with pH. The family Kickxellaceae which predominated in deeper soil (15–22.5 cm), had an opposite response to soil OM. Furthermore, some taxa in Ascomycota, such as Hypocreales, Peziza and Penicillium, were increased by liming at one of the locations (Moro). In conclusion, these findings suggest that fungal community structure and composition rather than fungal diversity responded to location, soil depth and liming. Compared to liming, location and depth had a stronger effect on the soil fungal community, but some specific fungal taxa shifted with lime application.

Abstract:
Las orquídeas mantienen en la naturaleza estrechas relaciones con hongos. Durante el trabajo con la reproducción in vitro de Laelia speciosa observamos al microscopio que semillas y plántulas presentan infestación de hongos en diversos tejidos. También se analizaron plantas adultas colectadas en el campo. Para identificar a los hongos e inferir el papel de su presencia en la planta secuenciamos su ADN. Se extrajo ADN de tejidos esterilizados superficialmente como raíz, hoja, cápsula y semillas; luego se amplificó la región del ITS ribosomal con los primers ITS1F e ITS4. Posteriormente se clonaron los fragmentos con TOPO TA4 y se secuenciaron usando la química de Big Dye terminator en un ABI 3100. En total se secuenciaron más de 150 clones positivos, de éstos el 50% correspondieron a secuencias de L. speciosa, aunque los primers empleados en teoría son específicos para hongos. El resto de las secuencias agrupadas en 97% de similitud correspondieron a 19 especies de hongos de los géneros Alternaria, Cylindrocarpon, Curvularia, Fusarium, Myrmecridium, Neonectria, Penicillium, y Tetracladium, así como a especies desconocidas de los Helotiales, Lasiosphaeriaceae, Nectriaceae, Pucciniomycotina, Sordariomycetes, y Tricholomataceae. Muchos de estos taxa están presentes en las semillas, lo que sugiere que estos hongos llegan a éstas vía placenta. En algunos casos, hongos parásitos, causan la muerte de las semillas y en otros casos, hongos micorrízicos, facilitan su germinación. La diversidad de hongos endófitos en L. speciosa es considerable y la biología de los organismos involucrados es diversa y va desde los parásitos y saprobios hasta los micorrízicos.

Abstract:
ABSTRACTMany agricultural soil management strategies have been shown to be effective in preventing soilborne diseases. However, their underlying mechanisms of action remain unknown. In this study, we used reductive soil disinfestation (RSD), also named anaerobic soil disinfestation (ASD) and biological soil disinfestation (BSD), as a representative method for disease management and cucumber damping-off diseased soil as a model system to identify the disease-suppressive agents in artificially managed soil. The results showed that RSD created a soil environment that was different from that of the diseased soil, where the pH level and the carbon content were greater. Heat treatment and pathogen or soil microbiota self- and cross-reinoculations resulted in the expansion of various soil microbial communities harbored by the two soil environments, as well as various disease incidences. Environmental factors were the primary determinant of the reassembled bacterial community, followed by initial microbiota, whereas initial microbiota was the key driver of the reassembled fungal community. The relative abundances of the bacterial orderSphingobacterialesand fungal order Sordariales, as well as their affiliated generaSphingobacterium, unclassified genus withinSphingobacteriaceae,Zopfiella, and unclassified genera within Lasiosphaeriaceae and Chaetomiaceae, were negatively correlated with disease incidence and positively associated with RSD-conditioned soil environment. Furthermore, we validated that both the microbial disease-suppressive agent and its adapted abiotic environment contributed to disease suppression. Our results elucidate the abiotic and biotic foundations of soilborne disease suppression under artificial management and highlight that the abiotic environment is as important as the microbial agents in disease suppression.IMPORTANCEMost defined systems have identified microbial elements as the primary factors determining disease suppression, but the involvement of the soil abiotic environment is less defined. The significance of this work is that the soil abiotic environment plays a critical role in the establishment of the soil microbial community and key microbial agents that directly contribute to the prevention of soilborne diseases. We highlight the importance of the soil abiotic environment in disease suppression. Furthermore, we provide a framework for the characterization of disease-suppressing agents in artificially managed soil. These results will gradually close the gap in knowledge on soil environment-microbe interactions.
