Ultrastructure of sclerotia of Aspergillus alliaceus
Transactions of the British Mycological Society, 1982The sclerotium of Aspergillus alliaceus consists of a pseudoparenchymatous medulla of isodiametric elements, 10–15 μm diam, and a rind of three to four layers of ellipsoidal elements, 3–4 × 5–8 μm, with thinner walls. Wall thickness increases considerably during sclerotium development, reaching 2–3 μm in the medulla and 0.5–1 μm in the rind. The outer

Mycoparasitism of Sclerotia of Sclerotium Cepivorum.
Australasian Plant Pathology, 1989Four fungal species were recorded in vitro as potential mycoparasites of sclerotia of Sclerotium cepivorum, the causal agent of onion white rot. Parasitised sclerotia appeared shrunken and decayed and failed to germinate. Light and scanning electron microscopy revealed colonisation of the internal structure of the sclerotium by the mycoparasites.

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 ...

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 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.

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.

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 ...

Testing the viability of fungal sclerotia
Annals of Applied Biology, 1970SUMMARYSimple methods for producing, handling and testing the viability of sclerotia were used on five fungi, three of which produced sclerotia freely in sand‐maizemeal cultures; the other two did not, and were grown on agar. After air drying, which did not affect viability, sclerotia were buried in the field in bags of nylon fabric.

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.

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
