Abstract A description is provided for Microsporum distortum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded on man, monkey, dog and horse. Some human infections have been in children with a history of contact with cats with skin lesions but these animals were not examined by culture. Rats, guineapigs, rabbits and cats have been experimentally infected. DISEASE: Ringworm (dermatophytosis tinea). Similar to M. canis infections. Infected hairs fluoresce pale to bright green under Wood's light and are encrusted with ectothrix sheaths of small spores in a mosaic arrangement. In man, the scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Most reported infections have been in children under 7 years old. Scalp lesions have been reported only in children, and usually consist of scaling patches of alopecia, with some erythema at the margin. Skin lesions are usually small, circular, with erythematous borders and dry, scaling centres. In animals scaling patches of alopecia are the usual symptom. GEOGRAPHICAL DISTRIBUTION: Australia (New South Wales), New Zealand (apparently restricted to Otago), U.S.A. (Iowa, Ga). All cases reported from U.S.A. have been in pet monkeys probably recently imported from Central America, and in humans and dogs which had been in contact with the monkeys.

Abstract A description is provided for Phacidiopycnis tl jberivora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Solanum tuberosum, Alnus, Beta, Escallonia, Eucalyptus, Hoya, Humulus, Medicago, Olearia, Ribes, Syringa, Vaccinium and probably several other plants. DISEASE: Stem-end hard rot or progressive dry rot, or corky rot of potatoes (11, 671; Foster & Macleod, 1932). Symptoms are variable; on mature tubers lesions vary in size from pin heads to those involving the whole tuber. With the progress of infection lesions become sunken, circular with a well defined margin. When immature tubers become infected they become mummified (Foster & Macleod, 1932). GEOGRAPHICAL DISTRIBUTION: Asia (India); Australasia and Oceania (Australia, New South Wales, New Zealand); Europe (UK); North America (Canada, Alberta, Vancouver, British Columbia; USA, Washington). TRANSMISSION: No specific studies reported. Probably by conidia discharged during alternating dry and wet conditions; penetration of tubers through wounds and abrasions.
