Colletotrichum gloeosporioides: Biology, Pathogenicity and Management in India Colletotrichum is one of the major plant pathogen causing anthracnose, a disease on variety hosts from trees to grasses. In present article we studied taxonomy, biology pathogenicity gloeosporioides taxonomical descriptions based morphological, microscopic molecular approach carried out India are also discussed detail. Biology with respect its growth conditions detailed symptoms anthracnose presented.

Puccinia species (Pucciniaceae, Pucciniales) are plant pathogens worldwide and characterized by their host association, morphology, molecular data. In this study, two new of Puccinia, collected from grass Carex scaposa in Yunnan Province, China, were identified based on phylogeny morphology. They described as kunmingensis P. caricis-scaposae. is its exceptionally long pedicels caricis-scaposae represents the first inhabiting scaposa.

Caves offer distinct environmental conditions that foster fungal diversity, and to date, over 2,000 species have been recorded in cave ecosystems. During our surveys of fungi Yunnan Province, China, we isolated several intriguing strains. Detailed morphological characteristics combined multi-locus phylogeny internal transcribed spacer (ITS), RNA polymerase II subunit 2 (RPB2), translation elongation factor 1-alpha (TEF1-α) revealed four new isolates represent a (Trichoderma cavernicola) host...

A systemic study of fungal endophytes associated with different plant parts Cannabis sativa and their antifungal activity was investigated in the present study. total 281 segments, including 91 leaves, 93 stem 97 petioles samples, were screened for isolation endophytic fungi. Totally, 212 (77.65%) segments found colonised by Highest colonisation frequency observed (84.94%), then leaves (82.41%) lowest 59.79% petiole. Total eight genera belonging to 12 species isolated. Aspergillus is...
