We studied the density of ascocarps (mushrooms) of morels (Morchella) and pixie cups (Geopyxis carbonaria) as a function of postfire duff (forest floor organic layer) depth in the first 4 y after a wildfire. The great majority of ascocarps of both species appeared in the first summer (2004) after an Aug 2003 fire in predominantly pine-spruce montane stands in Kootenay National Park, British Columbia. The spatial distribution of the ascocarps of both species was strongly biased toward (i… Expand
Observations on post-fire black morel ascocarp development in an Israeli burnt forest site and their preferred micro-sites
TLDR
Observations enhance understanding the ecological principles underlying the distribution and abundance of morel ascocarp development in natural habitats; such an understanding could contribute to conservation and management ofMorel fruiting in the wild. Expand
Post-fire morel (Morchella) mushroom abundance, spatial structure, and harvest sustainability
Abstract Morel mushrooms are globally distributed, socially and economically important reproductive structures produced by fungi of the genus Morchella . Morels are highly prized edible mushrooms andExpand
Controlled surface fire for improving yields of Morchella importuna
TLDR
Investigation of fire treatment on the occurrence and yield of the morel Morchella importuna in semi-artificial, field-based setups found that surface fires increased the suitability of soils for the growth and productivity of ascocarps of M. importuna if sufficient burning material is used. Expand
Isotopic evidence indicates saprotrophy in post-fire Morchella in Oregon and Alaska
TLDR
It is concluded that morels fruiting in post-fire environments in the study assimilated old carbon and were saprotrophic. Expand
Phylogenetic diversity of true morels (Morchella), the main edible non-timber product from native Patagonian forests of Argentina.
TLDR
The phylogenetic analyses suggested that the third species from Patagonia was nested within the species-rich Elata Subclade and represents a new species-level lineage (informally designated Mel-37) within Elata Clade. Expand
Pyrophilous fungi detected after wildfires in the Great Smoky Mountains National Park expand known species ranges and biodiversity estimates
TLDR
Most pyrophilous fungi identified in this study are either cosmopolitan or have a Northern Hemisphere distribution, but cryptic endemic lineages were detected in Anthracobia and Sphaerosporella. Expand
Truffles and Morels: Two Different Evolutionary Strategies of Fungal-Plant Interactions in the Pezizales
TLDR
This chapter describes and compares the two groups of mushrooms and takes a look at the evidence as to whether there are real trophic differences from those traditionally held and if things are not quite as simple as the authors' forebears would have had us believe. Expand
Soil bacterial and fungal response to wildfires in the Canadian boreal forest across a burn severity gradient
Abstract Global fire regimes are changing, with increases in wildfire frequency and severity expected for many North American forests over the next 100 years. Fires can result in dramatic changes toExpand
Soil Bacterial and Fungal Response to Wildfires in the Canadian Boreal Forest Across a Burn Severity Gradient
TLDR
It is found that fire occurrence, along with vegetation community, moisture regime, pH, total carbon, and soil texture are all significant predictors of soil microbial community composition, and that accounting for burn severity improves understanding of their response to fires, with potentially important implications for ecosystem function. Expand
Wildfire severity reduces richness and alters composition of soil fungal communities in boreal forests of western Canada.
TLDR
This study used an extreme wildfire event in boreal forests of Canada's Northwest Territories to test drivers of fungal communities and assess relationships with plant communities, and found soil pH and fire severity and interactions between these drivers were important for fungal community structure.

The postfire discomycete Geopyxis carbonaria (Ascomycota) is a biotrophic root associate with Norway spruce (Picea abies) in nature
TLDR
The hypothesis that the postfire discomycete Geopyxis carbonaria has a biotrophic association with roots of Norway spruce in nature was tested by isolation of fungal strains from fresh, brown, smooth mycorrhiza‐like root tips of NorwaySpruce collected from below the depth of detrimental heat penetration in a postfire site.

Biotrophic associations between lodgepole pine seedlings and postfire ascomycetes (Pezizales) in monoxenic culture
TLDR
Twenty-two species of postfire ascomycetes belonging to the order Pezizales were screened for biotrophic interactions with roots of lodgepole pine, and the only confirmed mutualistic species was Sphaerosporella brunnea, which formed ectendomycorrhizae. Expand
Seedbed variation from the interior through the edge of a large wildfire in Alberta
Despite the importance of seedbeds in the life histories of many plant species, there has been little study of the seedbeds created by wildfire in fire-prone vegetation types such as the borealExpand
Ecology of the 2004 morel harvest in the Rocky Mountain Forest District of British Columbia
TLDR
Several plant species had high importance in morel habitat, and were also associated with above-average morel abundance: Chamerion angustifolium (L.) Holub, Arnica cordifolia Hook. Expand
High-elevation gray morels and other Morchella species harvested as non-timber forest products in Idaho and Montana

Spatial and temporal patterns of morel fruiting.
TLDR
The spatial pattern of M. esculenta fruiting appears to be associated with vegetation pattern, whereas the onset and abundance of fruiting are determined by the interaction of spring temperatures with availability of supporting precipitation. Expand
Productivity and diversity of morel mushrooms in healthy, burned, and insect-damaged forests of northeastern Oregon
Abstract Large commercial crops of morels are harvested annually from montane coniferous forests of the northwestern United States. Although some morels fruit annually in nondisturbed forests, othersExpand
Field observations on growth and development of Morchella rotunda and Mitrophora semilibera in relation to forest soil temperature
TLDR
Field data correlate the initial extent of springtime reheating of soil with ascocarp maturation and suggest that mycelial muffs may be storage and resistance structures formed as early as the summer preceding the spring fruiting, which suggests morels are biennial. Expand

Synthesis of two types of association between Morchella esculenta and Picea abies under controlled culture conditions
TLDR
Morels can grove as saprophytes, but in association with trees, they form sclerotia around mature roots and ectomycorrhizas with rootlets, which apparently helps the fungus for mycorrhization. Expand
