Lumi-ergometrine – structural identification and occurrence in sclerotia

Mycotoxin Research, 2011
The 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, 1977
Germination 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 ...

Dating of Sclerotia Grains in Andosol Profiles

2021
Sclerotia 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 ...

Antibiotics in sclerotia and mycelium of Rhizoctonia species

Transactions of the British Mycological Society, 1985
The sclerotia and mycelium of a number of species of Rhizoctonia were found to contain materials having antibiotic properties. Those of R. cerealis, R. oryzae-sativae and R. tuliparum were particularly effective. Most antibiotic-producing species were binucleate. Chromatographic evidence indicated that the antibiotics produced by R. cerealis, R.

The Ontogeny of the Sclerotia of Pyronema Domesticum

Mycologia, 1962
Pyronema 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.
