Abstract
Trichoderma form-species are among of the important antagonists of plant pathogenic fungi and also induce resistance in field crops. Therefore their isolation and identification could be helpful for applying them in biological control. They isolate by pour soil diluted suspension on Dawet, Peptone – Rose Bengal, or modified Potato- Dextrose-Agar mediums. Species can identify based on colony characteristics, growth characteristics and morphological characteristics of conidiophores, phialids, and conidia. Eighty-five isolates of Trichoderma from 25 soil samples, from 8 regions of the Fars province sugar beet fields, isolated and purified with this method. With studied their characteristics eight form-species of Trichoderma identified with names: T. asperellum, T. atroviride, T. brevicompactum, T. harzianum, T. longibrachiatum, T. spirale, T. tomentosum and T. virens . Methods of isolation, identification and morphological characteristics of these fungi described.

Amirmijani, A. M. 2019. Important characters in identification of
Cladosporium spp.
Plant Pathology Science 8(1):50-59. DOI: 10.2982/PPS.8.1.50.
The genus Cladosporium is one of the largest genera of fungi. Its species live in different ways: as plant pathogens, as saprobes in the soil or on decaying plant materials, or as hyperparasitic on other fungi. Morphological characteristics of conidia such as shape, formation and surface ornamentation, the features of conidiophores including shape, ramification and conidiogenous loci, and sequencing data from different regions of DNA are very important for identification of Cladosporium species. In this article the important morphological characteristics and genomic regions which are useful for identification of closely related or cryptic species of this genus, are illustrated.
