ABSTRACT

 

Tsay, J. G., and Hsieh, W. H. 1993. Some new recorded Diaporthe fungi from Taiwan. J. Chia-Yi Ins. Agr.(Taiwan, R.O.C.) 34: 81-92.

Altogether thirty-seven specimens belong to Diaporthe were collected from July, 1990 to December, 1991. Six Diaporthe fungi new records from Taiwan are described. These are Diaporthe arctii (Lasch) Nitschke, D. conorum (Desmazieres) Niessl, D. eres Nitschke, D. nomurai Hara, D. pustulata (Desmazieres) Saccardo, and D. spiculosa (Albertini et Schweinitz) Nitschke.

(Key words: Diaprothe, Taiwan)

 

INTRODUCTION

 

The Diaporthaceae form their perithecia immersed in a stroma with only their long beaks protruding. The ascus has an apical refractive ring. The ascospores are hyaline and two-celled. The largest genus in this family is Diaporthe. There are a direct correlation between ascigerous and conidial stages. The imperfect stage of Diaporthe species all belong to the form-genus Phomopsis (1).

According to the List of Plant Diseases in Taiwan(2), Diaporthe citri, D. pomigena, D. vexans and 12 species of Phomopsis were recorded in Taiwan. Two monographs of Diaporthe had been published in other countries(2,4). The purpose of this study deals with the general survey of Diaporthe in Taiwan. The delimited works are based on the Kobayashi(2) and Wehmeyer(4).

 

MATERIALS AND METHODS

 

The materials were collected from various location in Taiwan from July, 1990 to December, 1991(Table 1). All collections were made with the dead twigs by keeping them in paper bags at room temperature. Measurements of conidia, perithecia, asci, and ascospores were made over twenty replications as possible for the fungus on twig. All specimens were drawed under 150 X and 600 X magnification of Olympus microscope with the aid of micrometer and Olympus drawing tube. Herbarium packets were labeled with host species, fungal species, collector, collection date, collection area. All specimens collected have been deposited at the mycology laboratory of Department of Plant Pathology, National Chung Hsing University.
