Abstract Schizothecium encompasses species whose morphological features make them easily confused with Podospora and Cercophora. This study, carried out between September 2008 and October 2010, set out to characterize Schizothecium species from wildlife dung and determine their ecological attributes. Dung from Cape buffalo, zebra, giraffe, hippopotamus, impala, Jackson’s hartebeest, sable antelope and waterbuck was incubated in a moist chamber culture. Morphological features of sporulating ascomycetes were used to characterize and identify the species. Five species, Schizothecium conicum, S. curvuloides var. curvuloides, S. dakotense, S. dubium and S. glutinans were isolated and described. Schizothecium dakotense, S. dubium and S. glutinans are new records. Schizothecium curvuloides var. curvuloides and S. dakotense were fairly common.

Abstract Strains of Colletotrichum were isolated from the fruits of chili, coffee, longan, mango, papaya and rose apple, collected from orchards and markets in Laos and Thailand. Isolates were identified using morphological characters, colony growth rate, and confirmed with DNA sequence data analysis of combined multi-gene loci. Pathogenicity testing of ten strains representing five species of Colletotrichum was carried out on Capsicum sp. (chili), Carica papaya (papaya), Citrus reticulata (orange), Eugenia javanica (rose apple), Mangifera indica (mango) and Psidium guajava (guava) using a wound drop technique. Pathogenicity and potential for cross infectivity of Colletotrichum asianum, C. cordylinicola, C. fructicola, C. saimense and C. simmondsii were tested on the hosts. The Colletotrichum strains belonging to different species tested were generally shown to infect a wide host range.

Abstract In our studies to document the diversity and distribution of coprophilous ascomycetes in Kenya, we collected several species in Chaetomium. This genus, comprises a large group of saprobic ascomycetes growing on dung and other cellulose-rich substrates. In the present study we collected wild animal dung from different ecosystems in Kenya. The dung substrate was laboratory cultured using a moist chamber method. Five taxa, Chaetomium convolutum, C. globosum, C. muelleri, C. seminis-citrulli a new record and Chaetomium sp., probably a novel species, are examined, described and illustrated. Chaetomium convolutum and C. globosum are the most common taxa in the dung studied. Chaetomium seems to have a preference of growing on browser animal dung.
