Abstract:
The abundance and distribution of rhizomorphs of Armillaria spp. in the soil were quantified in undisturbed stands and in stands defoliated 1 and 5 years previously by insects. Although the species of Armillaria was not determined, similar mixed oak forests in south central Pennsylvania contain North American biological species VII (Armillariabulbosa Barla.). Several analysis techniques were tested for sensitivity to differences in distribution of rhizomorphs. Rhizomorph distribution within the 0.04-ha study plots was uniform in the undisturbed stands, but was significantly greater near dead trees in the defoliated stands. Total rhizomorph abundance was greater on plots defoliated 5 years before sampling than on more recently defoliated plots, and it was least on undefoliated plots. Rhizomorph density near dead trees was highly correlated with overall rhizomorph density. Greater rhizomorph abundance near recently dead trees or stumps may have important implications for management decisions in the presence of gypsy moth (Lymantriadispar L.) infestations.

Abstract:
Antagonistic Effects ofTrichodermaSpecies in Biocontrol ofArmillaria Melleain Fruit Trees in IranRoot and butt rot caused by species ofArmillariais one of the most serious diseases of fruit and forest trees in Iran. In this study, antagonistic effects ofTrichodermain biocontrol ofArmillariawere investigated.Armillaria melleawas isolated from infected roots and butts of cherry and almond trees and identified with pairing tests method.Trichodermaspecies were recovered from rhizomorphs and around soil ofArmillariainfected roots.Trichodermaspecies identified wereT. virens(nine isolates) andT. harzianum(three isolates).Trichodermadiscs were placed onto cultures ofArmillariato study antagonistic effects. All isolates ofTrichodermacolonizedArmillariacolonies within 5-7 days. Volatile compounds ofTrichodermaisolates inhibitedArmillariacolony growth and rhizomorph formation. Mechanisms of biocontrol were investigated by light and scanning electron microscopy, these included penetration ofTrichodermahyphae in rhizomorphs, colonization of rhizomorphs byTrichodermamycelia, colonization of apex meristemic center and apical buds of rhizomorphs, sporulation ofTrichodermain outer and inner surface of rhizomorphs, degeneration and lysis of rhizomorph tissue, and discharge of rhizomorph content.

Abstract:
Abstract A comparative experiment was carried out in growth chambers to determine the effects of elevated CO2 concentrations (either 760 ppm or 1,140 ppm) versus ambient CO2 conditions on the growth of Armillaria ostoyae (Romagn.) Herink rhizomorphs, which is the infectious organ of a fungal pathogen affecting many forest trees. We found that one out of three isolates in the experiment differed significantly in rhizomorph production, which was measured as rhizomorph dry mass/100 days of growth. Rhizomorph production was also affected by the tree species used as a food source in the inoculum preparation, with beech wood being significantly different from oak and hazel. Under higher CO2 regimes the production of rhizomorphs was consistently lower for all three isolates compared to ambient CO2 concentrations. For one isolate (no. 11) the growth differences were significant between 380 ppm and both elevated CO2 concentrations (760 ppm and 1,140 ppm), while for the other two (no. 30 and 32) significance was observed only between 380 ppm and 760 ppm. No statistically significant differences have been noted between 760 ppm and 1,140 ppm CO2 for these two isolates. it was concluded that elevated concentrations of CO2 inhibited A. ostoyae rhizomorph growth and therefore have the potential to lessen the pathogenicity of the fungus.

Abstract:
Lycophyte trees, up to 50 m in height, were the tallest in the Carboniferous coal swamp forests. The similarity in their shoot and root morphology led to the hypothesis that their rooting (stigmarian) systems were modified leafy shoot systems, distinct from the roots of all other plants. Each consists of a branching main axis covered on all sides by lateral structures in a phyllotactic arrangement; unbranched microphylls developed from shoot axes, and largely unbranched stigmarian rootlets developed from rhizomorphs axes. Here, we reexamined the morphology of extinct stigmarian systems preserved as compression fossils and in coal balls from the Carboniferous period. Contrary to the long-standing view of stigmarian systems, where shoot-like rhizomorph axes developed largely unbranched, root-hairless rootlets, here we report that stigmarian rootlets were highly branched, developed at a density of ∼25,600 terminal rootlets per meter of rhizomorph, and were covered in root hairs. Furthermore, we show that this architecture is conserved among their only extant relatives, herbaceous plants in the Isoetes genus. Therefore, despite the difference in stature and the time that has elapsed, we conclude that both extant and extinct rhizomorphic lycopsids have the same rootlet system architecture.

Abstract:
Cantharellus cibarius is a widely distributed, popular, edible fungus with high nutritional and economic value. However, significant challenges persist in the microbial ecology and artificial cultivation of C. cibarius. Based on the 16S rRNA sequencing data, this study analyzed bacterial community structures and diversity of fruit bodies and rhizomorph parts of C. cibarius and mycosphere samples (collected in the Wudang District, Guiyang, Guizhou Province, China). It explored the composition and function of the core bacterial taxa. The analyzed results showed that the rhizomorph bacterial community structure was similar to mycosphere, but differed from the fruit bodies. Members of the Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium complex had the highest abundance in the fruit bodies. However, they were either absent or low in abundance in the rhizomorphs and mycosphere. At the same time, members of the Burkholderia-Caballeronia-Paraburkholderia complex were abundant in the fruit bodies and rhizomorphs parts of C. cibarius, as well as mycosphere. Through functional annotation of core bacterial taxa, we found that there was an apparent trend of potential functional differentiation of related bacterial communities in the fruit body and rhizomorph: potential functional groups of core bacterial taxa in the fruit bodies centered on nitrogen fixation, nitrogen metabolism, and degradation of aromatic compounds, while those in rhizomorphs focused on aerobic chemoheterotrophy, chemoheterotrophy, defense against soil pathogens, decomposition of complex organic compounds, and uptake of insoluble inorganic compounds. The analysis of functional groups of bacteria with different structures is of great significance to understand that bacteria promote the growth and development of C. cibarius.

Abstract:
Abundance of rhizomorphs of Armillaria was characterized in 1995-1996 in 32 plots located in sugar maple (Acer saccharum Marsh.) stands in the Susquehannock State Forest (Pennsylvania, U.S.A.). All of the plots were thinned, and half of the plots were limed in 1985 when the plots were established. Frequency and abundance of Armillaria rhizomorphs in soil samples, on dead wood food bases (stumps, snags, fallen logs), and on the root collar of living sugar maples were determined in each plot. Rhizomorph vigor was evaluated by measuring their ability to colonize fresh striped maple (Acer pennsylvanicum L.) stem sections in the soil, or potato tubers in the laboratory. Isolates of Armillaria were obtained from rhizomorphs in the soil samples and species were determined by somatic incompatibility tests. Armillaria calvescens Bérubé & Dessureault was the major species present, representing about 66% of the isolates. Armillaria gemina Bérubé & Dessureault and Armillaria mellea (Vahl:Fr.) Kummer were also identified in the plots. Frequency of rhizomorphs in the soil, on food bases, abundance of rhizomorphs on root collars, as well as the proportion of rhizomorphs per plot that regenerated and (or) colonized fresh substrates were all correlated. However, abundance of ectotrophic rhizomorphs on the root collar was only weakly correlated with the other components of rhizomorph abundance and vigor. Frequency of the rhizomorphs as well as their ability to colonize fresh substrates were greater in plots either limed or with a high proportion of the basal area in sugar maple prior to thinning. By contrast, abundance of ectotrophic rhizomorphs on root collars was not affected by these factors.

Full text
Abstract:
Amaurodon aquicoeruleussp. nov. from Australia is characterised by rough, subglobose, bright blue spores and blue subiculum hyphae when mounted in water or KOH. No other species of Amaurodon with blue spores in water have been reported. Amaurodon aquicoeruleus has a green hymenium and superficially resembles A. viridis.Amaurodon aquicoeruleus possesses thin rhizomorphs that are formed by runner hyphae with clamp connections and by other, simple septate hyphae. This contrasts with the consistently clamp-bearing basidia and hyphae of the trama and subiculum. Rhizomorph formation is similar to the boletoid rhizomorph type but atypical of the closely related genus Tomentella. Discrete masses of structurally undamaged, mature basidiospores on the hymenium and at the fruit body margin of A. aquicoeruleus may be deposited by grazing insects.

Abstract:
Interaction between Armillaria species and seven other fungi were tested in vitro. Tree antagonistic (Trichoderma viride, Trichotecium roseum and Penicillium sp.) and four decaying (Hypholoma fasciculare? Hypholoma capnoides, Phlebiopsis gigantea, and Pleurotus ostreatus) fungi were chosen for this study. The best results were noted for Trichoderma viride, because fungus was able to kill both mycelia and rhizomorphs of Armillaria species, while Hypholoma spp. inhibited both growth of Armillaria colonies and rhizomorph production.

Abstract:
Yasuní National Park in Ecuador is one of the most biodiverse places on earth. The fungi in this tropical rainforest are also diverse but have received little research attention. This research paper focuses on an important group of fungi in the family Polyporaceae and examines the genera Polyporus, Atroporus, and Neodictyopus that form aerial melanized cord-like structures called rhizomorphs. Phylogenetic analyses, macro and micromorphological descriptions of basidiomata and rhizomorphs, as well as cultural characterization were completed to better understand these ecologically important fungi. Here we describe four new species: Atroporus yasuniensis, Atroporus tagaeri, Neodictyopus sylvaticus, and Polyporus taromenane, and a new variety Polyporus leprieurii var. yasuniensis. The information presented in this study adds important new knowledge about the unusual rhizomorph producing fungi found in Yasuní National Park, Ecuador and other tropical rainforests.

Abstract:
The internal structure of mature mycelial cords of Lycoperdon pyriforme, Mutinus caninus, Steccherinum fimbriatum, and Tricholomopsis platyphylla was studied using scanning electron microscopy. Although interspecific differences in the degree of internal differentiation were observed, linear mycelial organ structure in all four species was similar, in that they consisted of a cortex of fine hyphae surrounding a medulla containing large diameter "vessel" hyphae. Based on similarities between the internal structure of rhizomorphs of Armillaria mellea and the mycelial cords of the species considered in this study, the exclusive use of the term "rhizomorph," qualified by adjectives describing development at the growing front and the degree of internal differentiation, is proposed in describing all linear mycelial aggregates.

Abstract:
Two different types of rhizomorphs were produced by A. luteobubalina in vitro conditions - aerial and submerged. They differed in growth rate, amount of mucilage, extent of peripheral hyphae, degree of pigmentation and in the structure of inner cortex. Otherwise they had a similar internal structure comprising 4 radial zones, namely, peripheral hyphae, outer cortex, inner cortex and medulla. Two membrane permeant symplastic fluorescent tracers, carboxy-DFFDA and CMAC which ultimately sequestered in vacuoles, behaved in a similar fashion in aerial and submerged rhizomorphs regardless of whether pigment was present in the outer cortical cell walls or in the extracellular material. Rhizomorphs appeared to be mostly impermeable to these probes with exception of a few fluorescent patches that potentially connected peripheral hyphae to inner cortical cells. In contrast, the apoplastic tracer HPTS which was applied to fresh material and its localisation determined in semi-thin (dry) sections following anhydrous freeze substitution appeared to be impeded by the pigmentation in cell walls and/or the extracellular material in the outer cortical zone. Structures identified as air pores arose directly from the mycelium and grew upwards into the air. A cluster of rhizomorph apices is initiated immediately beneath the air pores. As air pores elongated they differentiated into a cylindrical structure. Mature air pores became pigmented as did also the surface mycelium of the colony. The pigmented surface layer extended into the base of air pores, where it was elevated into a mound by tissue inside the base of the air pore. Beneath the pigmented surface layer there was a region of loose hyphae with extensive gas space between them. This gas space extended into the base of the air pore and was continuous with the central gas canal of rhizomorphs. Oxygen is conducted through the air pores and their associated rhizomorph gas canals into the oxygen electrode chamber with a conductivity averaging 679??68x10-12 m3s-1. The time averaged oxygen concentration data from the oxygen electrode chamber were used to compare three different air pore diffusion models. It was found that the widely used pseudo-steady-state model overestimated the oxygen conductivity. Finally, a model developed on the basis of fundamental transport equations was used to calculate oxygen diffusivities. This model gave a better comparison with the experimental data.

Abstract:
Dans le sol, les racines absorbent des ions mineraux qu'elles transportent vers les parties aeriennes, ou qu'elles accumulent dans leur cortex. Il arrive que ces ions y cristallisent. Les structures rhizomorphes calcaires sont des vestiges de racines calcifiees, dont l'organisation est analogue a celle des microdiums. Elles se developpent dans de nombreux sols calcaires. L'analyse de leur organisation nous amene a emettre l'hypothese que leur formation resulte d'une redistribution sur place du caco::(3) du sol consecutive a l'absorption et a l'accumulation de ca**(2+) par les racines. Cette hypothese est confirmee par la mise en evidence experimentale de cristaux intracellulaires de caco::(3) dans les racines de colza (brassica napus l. ) cultivees en solution calcique riche en carbonate
