“…Field observations showing that the base of ascocarps adheres to roots or rhizomes of plants initially led to speculation that morels were parasitic (Robert, 1865;Condamy & Cornu, 1878;Roze, 1882Roze, , 1883 or ectomycorrhizal (Matruchot, 1909). Later, the abundant and rapid growth of the mycelium in pure culture on a wide range of synthetic culture media (Molliard, 1904;Fron, 1905;Melin & Gunhild, 1941;Brock, 1951;William, Trzcinski & William-Engels, 1956;Impens, 1972;Kaul, 1977;Wassom & Holden, 1977) indicated the potential of morel mycelium for saprophytism.…”

SUMMARYA histo-cytological study of Norway spruce [Picea abies (L.) Karst.] roots connected to ascocarps of Morchella rotunda (Pers.) Boudier revealed that hyphae of morel were associated with all parts of the root system. The main suberized roots were surrounded by a mycelial sheath. The finer rootlets were enveloped by a cottony mycelium and their absorbing root tips were found to be ectomycorrhizal. Morel hyphae also invaded the oldest parts of a heterobasidiomycete ectomycorrhiza.

“…This is unusual in view of the fact that Fron (1905) reported inulin to be a very good carbon source. M. esculenta has also been found parasitizing the rhizomes of Helianthus tuberosus (Roze, 1883), which are high in inulin content. It is possible that strain differences might ac?…”

“…Because of its high economic value, indoor cultivation of morel mushrooms has received considerable attention worldwide (Du et al, 2015). Outdoor cultivation of morel mushrooms was first performed in France and was reported by Roze (1882) in relation to Jerusalem artichokes (Liu et al, 2018). Successful indoor cultivation of morels was first reported in 1982 by Owwer (1982).…”

Morel mushroom (Morchella spp.) is a rare edible and medicinal fungus distributed worldwide. It is highly desired by the majority of consumers. Bacterial diseases have been commonly observed during artificial cultivation of Morchella sextelata. Bacterial pathogens spread rapidly and cause a wide range of infections, severely affecting the yield and quality of M. sextelata. In this study, two strains of bacterial pathogens, named M-B and M-5, were isolated, cultured, and purified from the tissues of the infected M. sextelata. Koch’s postulates were used to determine the pathogenicity of bacteria affecting M. sextelata, and the pathogens were identified through morphological observation, physiological and biochemical analyses, and 16S rRNA gene sequence analysis. Subsequently, the effect of temperature on the growth of pathogenic bacteria, the inhibitory effect of the bacteria on M. sextelata on plates, and the changes in mycelial morphology of M. sextelata mycelium were analyzed when M. sextelata mycelium was double-cultured with pathogenic bacteria on plates. The results revealed that M-B was Pseudomonas chlororaphis subsp. aureofaciens and M-5 was Bacillus subtilis. Strain M-B started to multiply at 10–15°C, and strain M-5 started at 15–20°C. On the plates, the pathogenic bacteria also produced significant inhibition of M. sextelata mycelium, and the observation of mycelial morphology under the scanning electron microscopy revealed that the inhibited mycelium underwent obvious drying and crumpling, and the healthy mycelium were more plump. Thus, this study clarified the pathogens, optimal growth environment, and characteristics of M. sextelata bacterial diseases, thereby providing valuable basic data for the disease prevention and control of Morchella production.
