“…These fungi have been considered by other researchers to be early successional fungi found in nursery-grown conifers and following fire (Wilcox et al 1974(Wilcox et al , 1983Wilcox 1984, 1985;Mikola 1965;Lahio 1965;Danielson 1982Danielson , 1984Scales andPeterson 1991, Visser 1995). This correlates well with the production of abundant ascocarps of known biotrophic fungal genera such as Morchella (Buscot and Kottke 1990), Gyromitra, Sphaerosporella, and Tricharina present at our research sites throughout the summer of 1989.

Ectomycorrhiza formation, survivability, and physiognomic characteristics were assessed for conifer seedlings encountered 1 and 2 years postfire in the Huck burn site near Grand Teton National Park. Pinus contorta Dougl. ex Loud. germinated and was abundant throughout the first growing season. Abies lasiocarpa (Hook.) Nutt. germinated during May and June but was rarely encountered by September. First-year survivorship of P. contorta seedlings was about 50% for east-facing burn and edge and west-facing burn treatments. Mortality was higher in the west-facing edge treatment at about 64%. Pinus contorta seedlings collected in July and August had allocated approximately 75% more biomass to epicotyl production than to hypocotyl production, whereas by September seedlings had allocated 30-50% of their biomass to hypocotyls, regardless of site or treatment. Few or no ectomycorrhizae were formed until September. By September 100% of surviving seedlings were ectomycorrhizal. The number of ectomycorrhizae was positively correlated with the number of primary needles and the root/shoot ratio. These results highlight the importance of mycorrhizae to conifer seedling survival during the initial growing season and point to alteration of carbon allocation as a primary mechanism affecting seedling survival.Résumé : La formation des ectomycorhizes, leur capacité de survivre et leurs caractéristiques physionomiques ont été évaluées chez des semis de conifère présents 1 et 2 ans après feu dans le site brûlé de Huck près du parc national Grand Teton. Pinus contorta Dougl. ex. Loud. germait et était abondant pendant toute la première saison de croissance. Abies lasiocarpa (Hook.) Nutt. germait en mai et en juin mais a rarement été rencontré en septembre. La survie des semis de P. contorta était d'environ 50% la première année dans les zones brûlées exposées à l'est, dans le pourtour des zones brûlées et dans les zones brûlées exposées à l'ouest. La mortalité était plus forte, atteignant environ 64%, dans les zones brûlées exposées à l'ouest. Les semis de P. contorta prélevés en juillet et août avaient alloué environ 75% plus de biomasse à la production de l'épicotyle qu'à la production de l'hypocotyle, tandis qu'en septembre les semis avaient alloué 30 à 50% de leur biomasse à l'hypocotyle, quelque soit le site ou le traitement. Peu ou pas d'ectomycorhizes ont été observés avant le mois de septembre. En septembre, 100% des semis qui avaient survécu étaient mycorhizés. Le nombre d'ectomycorhizes était positivement corrélé avec le nombre d'aiguilles primaires et avec le ratio racine/tige. Ces résultats font ressortir l'importance des mycorhizes pour la survie des semis de conifère pendant la saison initiale de croissance et indiquent que le changement dans l'allocation du carbone est le principal mécanisme qui affecte la survie des semis.

“…Buscot and Kottke (1990, 1993) and Dahlstrom et al (2000) reported morels could form ectomycorrhizae with Pinaceae plants. Stark et al (2009) speculated morels were associated with orchids, based on evidence obtained through PCR-amplification directly from root-extracted DNA and cloning of the PCR products.…”

Morels, a group of the world’s most prized edible and medicinal mushrooms, are of very important economic and scientific value. Here, we review recent research progress in the genus Morchella, and focus on its taxonomy, species diversity and distribution, ecological diversity, phylogeny and biogeography, artificial cultivation, and genome. We also discuss the potential issues remaining in the current research and suggest some future directions for study.

“…Although recent studies suggest that morels can be mycorrhizal (Buscot 1992(Buscot , 1993Buscot and Kottke 1990;Dahlstrom et al 2000), mycologists have until recently classified them as saprobes, which acquire nutrients by breaking down decayed organic matter (Ower 1982). Understanding the distinction between saprobic and mycorrhizal life strategies is critical to establishing appropriate management regimes (Pilz et al 1999).…”

The Forest Service of the U.S. Department of Agriculture is dedicated to the principle of multiple use management of the Nation's forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research, cooperation with the States and private forest owners, and management of the national forests and national grasslands, it strives-as directed by Congress-to provide increasingly greater service to a growing Nation.The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, sex, religion, age, disability, political beliefs, sexual orientation, or marital or family status. This exploratory study examined aspects of the social organization of the commercial wild morel industry in western Montana during 2001. We talked with 18 key informants (7 buyers and 11 pickers) and observed social interactions at one buying station near the Kootenai National Forest and three buying stations near the Bitterroot National Forest. The key informant and observational data permitted us to construct a picture of social interactions at field buying stations, buyer strategies for attracting pickers, changes in prices over the course of a season, and the ways in which various participants in the wild morel harvest construct their livelihoods. In the discussion, we contrast our findings with the results of a recently published study on nontimber forest product harvesters in the Eastern United States. We end the report with a discussion of management implications for managers and scientists.
