Pure Culture Synthesis

In a special plant-growth room, isolates of Thelephora terrestris produced basidiocarps and formed typical ectomycorrhizae with seedlings of bristlecone, jack, sand, lodgepole, shortleaf, slash, sugar, Austrian, longleaf, cluster, ponderosa, red, pitch, eastern white, Scots, loblolly, and Virginia pines and Douglas fir. Atypical mycorrhizae (lacking mantle) were formed on seedlings of Norway spruce and jack, Japanese red, and Himalayan pines. The formation of atypical mycorrhizae was considered a result of differences in the symbiotic–parasitic nature of the fungal symbionts on different hosts. Pisolithus tinctorius formed typical mycorrhizae with seedlings of jack, sand, Japanese red, shortleaf, slash, Austrian, longleaf, cluster, red, pitch, eastern white, Scots, loblolly, and Virginia pines. Reisolation of specific fungal symbionts from mycorrhizae of several pine hosts was successful.Mycorrhizae formed by T. terrestris were macroscopically and microscopically different from those of P. tinctorius, but mycorrhizae formed by different isolates of T. terrestris were indistinguishable from each other, regardless of host. These results suggest that the fungal symbiont determines color and morphology of ectomycorrhizae.

En el vivero forestal de Junín de los Andes, Argentina (40º S, 71º W) se realizó un ensayo de inoculación micorrízica de presiembra en Octubre de 1988. Después de fumigar el suelo con Bromuro de metilo se formaron platabandas y se establecieron 30 parcelas de 1 m², separadas cada una por 30 cm, en un diseño de bloques al azar. La inoculación se realizó con inóculo sólido de Laccaria laccata, Hebeloma crustuliniforme, Thelephora terrestris y Pisolithus tinctorius, obtenido en medio Melin-Norkrans modificado. En cada bloque se usaron como controles 1 parcela con suelo de vivero y humus (1:1) y una con suelo de vivero solo. Después de la inoculación en la hilera se sembró semilla de Pinus ponderosa con una densidad de 0,5 kg/m². Tres meses más tarde se extrajeron 10 plantas al azar de cada parcela y se les midió el porcentaje de micorrización, el largo del tallo y raíz y sus respectivos pesos húmedos y secos. Los tratamientos T. terrestris y P. tinctorius fueron significativamente mejores en largo de tallo, proporción peso seco tallo/peso seco raíz e índice de calidad de las plantas. Ambos controles fueron significativamente mejores que el tratamiento L. laccata.

Phosphorus Levels

The objective of this study was to determine the different effects of three ectomycorrhizal fungi (Laccaria laccata, Hebeloma crustuliniforme, and Thelephora terrestris) on the growth and mineral nutrition of Pinus silvestris at different levels of soluble phosphorus. Even a low intensity of infection by Laccaria laccata stimulated Pinus silvestris growth greatly. The ability of this ectomycorrhizal fungus to increase Pinus silvestris growth seemed to be more related to its capacity to produce growth substances than to its capacity to stimulate phosphorus uptake. The poor efficiency of Hebeloma crustuliniforme compared with Laccaria laccata at any level of phosphorus could result from differences in diversion of carbohydrates from the host to fungal structures.

Para Determinar

En Chihuahua se han registrado cerca de 500 especies de hongos macromicetos, de las que 73 son consideradas comestibles a nivel mundial. El objetivo de la presente investigación fue determinar la composición proximal y mineral de cuatro especies de hongos ectomicorrícicos comestibles de la Sierra Tarahumara en Chihuahua. Se recolectaron carpóforos de Astraeus hygrometricus, Laccaria laccata, Amanita caesarea y Pisolithus tinctorius en dos localidades del municipio de Bocoyna. A éstos se les realizó un análisis proximal para determinar el porcentaje de humedad, proteínas, grasas totales, cenizas y carbohidratos totales, así mismo se realizó un análisis de composición mineral para determinar el porcentaje de nitrógeno total (N), fósforo (P), potasio (K), calcio (Ca), magnesio (Mg), sodio (Na), cobre (Cu), hierro (Fe), manganeso (Mn) y zinc (Zn). Los resultados muestran que P. tinctorius es la especie con mayor contenido de minerales, A. hygrometricus en contenido de carbohidratos, A. caesarea en contenido de grasas y L. laccata en proteínas. De los 10 distintos minerales que fueron determinados, A. caesarea presenta el contenido más elevado en N, P, K y Zn, mientras que A. hygrometricus tiene los valores más altos de Ca y Mn. Por su parte, L. laccata muestra los contenidos más altos en Mg, Na y Cu. Finalmente, P. tinctorius resultó con los valores más altos en Fe. En general, la composición proximal y mineral de estos hongos se encuentra dentro del rango establecido para hongos comestibles, por lo que son una buena alternativa alimenticia para los habitantes de la zona.

Pond Pine

Ectomycorrhizae were formed by pond pine after 4 months in monoxenic culture with Amanita muscaria, Cenococcum graniforme, Laccaria laccata, Pisolithus tinctorius, Suillus brevipes, S. cothurnatus, S. granulatus, S. hirtellus, and S. pictus. Phylloporus rhodoxanthus formed a fungal mantle but no Hartig net. Macroscopic characteristics which were used for distinguishing among species of fungi forming mycorrhizae in this study were type of branching, color of mycorrhizae, and production of rhizomorphic strands.

Temperature Optima

Geographically distinct isolates of the ectomycorrhizal fungi Pisolithus tinctorius, Cenococcum geophilum, Thelephora terrestris, and Suillus granulatus showed definite temperature optima for growth in pure culture. Temperatures promoting the greatest fungal growth varied interspecifically and intraspecifically over the temperature treatments of 16, 21, 27, 32, and 38 °C. Of the four fungal species, Pisolithus tinctorius exhibited the greatest growth at the higher temperature treatments, with growth optima for all isolates occurring between 21 and 32 °C. The maximum temperature for growth of Cenococcum geophilum was 27 °C, with optimal mycelial growth occurring between 16 and 27 °C, depending upon the particular isolate considered. Suillus granulatus showed greatest mycelial growth at 27 °C and below, with temperature optima for the different isolates ranging from 16 to 32 °C. The pure-culture growth of Thelephora terrestris was high relative to the other fungal species examined with growth optima between 21 and 27 °C. The degree of intraspecific variation of mycelial growth in response to temperature was high for all fungal species, indicating the existence of physiologically distinct genotypes. Attempts to relate fungal growth performance to geographic origin of isolate showed a trend for Pisolithus tinctorius. However, no such relationships were apparent for the other species.
