An action spectrum was determined for the photoinduced formation of perithecia in a homothallic strain of Nectria haematococca Berk. and Br. var. cucurbitae (Snyder and Hansen) Dingley. Dose-response curves for perithecial formation were obtained from 340 to 510 nanometers at 10-nanometer intervals. Radiation longer than 510 nanometers was not effective for inducing perithecial formation. The action spectrum indicated peaks of activity near 360, 440, and 480 nanometers with shoulders near 420 and 460 nanometers. Minima occurred near 350 nanometers, 390 to 410 nanometers, and 470 nanometers. The general shape of this action spectrum appears to be similar to those obtained for many different near ultraviolet-blue-sensitive organisms in which a flavoprotein molecule was postulated to be the photoreceptor.Previous research has shown that a photorequirement exists for proper development of asexual and sexual reproductive structures in several closely related strains of the fungus Nectria haematococca Berk. and Br. var. cucurbitae (Snyder and Hansen) Dingley (2,8,9,25,33 Baker (2) found that light intensity in particular had a marked effect on the production of the sexual (perithecia) stage. Of three intensities used, the optimal intensity for stimulating the production of perithecia in heterothallic strains was 190 to 195 ft-c.In a more comprehensive study of the light requirement, Curtis (8) found a broad optimal range of intensity for the production of perithecia from 50 to 250 ft-c. Darkness or higher intensities of irradiation greatly inhibited the formation of perithecial primordia and perithecia. In addition, a region of spectral sensitivity in the near UV-blue portion of the spectrum was found for two heterothallic strains and a homothallic strain.

Fuchsia species (Onagraceae) have been introduced into Indonesia as ornamental plants and are cultivated in gardens and parks of mountainous areas. A rust disease was found on leaves of Fuchsia macrostemma var. globosa at Cipanas, West Java, Indonesia in February 2010. There has been no previous report on the rust disease of Fuchsia species in Indonesia. Based on morphological characteristics of the causal rust fungus it was identified as Pucciniastrum epilobii. Its occurrence and morphology are reported.

“…These collections may be termed casual infections. It seems certain that many valid host records (e.g., Hirata 1966, Dingley 1969 fall into this latter category; e.g., Sphaerotlleca macl/faris (Fr.) laczewski on Rublls allstralis.…”

Powdery mildews from 66 host species were collected between 1972 and 1976, mainly from r.orthern New Zealand. Cleistothecia were found on the mildews from only foar h:>sts.It was possible to distinguish IS separate mildew entities on the basis of conidial characteristics. namely differences in gross morphology, presence or absence of cell inclusions as seen under polarised light, surface features as seen with a scanning electron microscope, and mode of conidial germination.Current taxonomic treatments of the Erysiphaceae nre reviewed and their relevance to the IS local entities is discussed.
