The term 'infrequent' is not strictly defined and is subject to personal experience. If there is any difficulty to decide whether 'infrequent' or 'abundant' should be used, enter both. But generally, if only a few sclerotia for one or several systems can be found, this is regarded as ’infrequent’. The frequency at least of those of Cenococcum appears to be influenced either by the soil type or by strain-specific differences.
