Sclerotia of the Gasteromycete Pisolithus tinctorius
Canadian Journal of Microbiology, 1980Hyphal masses, morphologically identified as the sclerotia of Pisolithus tinctorius, were found associated with root systems of containerized pine seedlings inoculated with this mycorrhizal fungus. The sclerotia are described and the results and method used for isolation are reported.

The development of sclerotia of certain fungi
Transactions of the British Mycological Society, 1954The development of sclerotia of six species of fungi was studied and three different methods of formation were distinguished. Sclerotial initials of Rhizoctonia solani develop by the increased branching and septation of the ordinary hyphae. The mature sclerotia are rather loosely constructed of brown barrel-shaped cells with dense contents ...

Large sclerotia of Sclerotium cepivorum
Transactions of the British Mycological Society, 1988Sclerotia of Sclerotium cepivorum much larger than typical infective sclerotia were common on naturally infected onions at Pukekohe, New Zealand, during one season but were rare in the next. They could not be recovered from soil one year after their most common occurrence. Similar large sclerotia were formed in culture on autoclaved wheat grains.

The respiration of sclerotia of Sclerotium rolfsii
Mycopathologia et Mycologia Applicata, 1967The respiration of sclerotia ofS. rolfsii was investigated using the Warburg constant-volume respirometer to measure oxygen uptake. The effects of age of sclerotia, pH, and temperature were studied. Sclerotia produced on prune agar were ideal for respirometric studies, being uniformly round and of approximately equal size.

Dating of Sclerotia Grains in Andosol Profiles
2021Sclerotia grains found from soils are not all active for germination but remain in soil. The age of sclerotia grains existing in soils is able to be estimated by 14C dating measurement. Sclerotia grains from surface A horizons and buried A horizons collected from Andosol profiles in central to northern Japan were found to have ages of 100–200 year BP ...

Lumi-ergometrine – structural identification and occurrence in sclerotia
Mycotoxin Research, 2011The fungus Claviceps purpurea grows on grasses and cereal grains and produces six predominant ergot alkaloids. These toxic substances undergo different transformation reactions during storage and cereal processing. One of these reactions is the addition of water to a double bond in the ergoline skeleton.

Germination Requirements of Claviceps Paspali Sclerotia
Mycologia, 1977Germination of Claviceps paspali sclerotia occurred over a wide range of storage and incubation temperatures. Cold, moist storage conditions greatly enhanced germination but were not obligatory. Highest percentage germination and most rapid germination occurred after storage in moist sand at 5 and 10 C for 2 mo followed by incubation at 20 C for 41-44 ...

Soil Biology and Biochemistry, 1983
Abstract The proportion of viable sclerotia of Sclerotium cepivorum placed in field plots in Burnaby, British Columbia, decreased with time ( P = 0.05). Sclerotia that had been air-dried for 48–72 hr had a lower percentage survival than those that had not been dried. Sclerotia placed on the soil surface decayed more rapidly than those buried at 15

The structure and histochemistry of sclerotia ofOphiocordyceps sinensis
Mycologia, 2008The structure and histochemistry of sclerotia of Ophiocordyceps sinensis (synonym: Cordyceps sinensis) are described. The remains of the caterpillar epidermis and sometimes setae of the caterpillar were attached to the pigmented layer that is external to the rind of the sclerotium.

The Ontogeny of the Sclerotia of Pyronema Domesticum
Mycologia, 1962Pyronema domesticum (Sow. ex Gray) Saccardo is a small, pyrophilous discomycete of the family Pezizaceae of the Pezizales. This organism occurs frequently on steam-sterilized soil and has been collected from greenhouses at Cornell University. This fungus is easily confused with P. omphalodes (Bull. ex St.-Amans) Fuckel [= P. confluens (Pers.
