Fungi associated with decomposing leaf litter of cashew (Anacardium occidentale)

Abstract

The biodiversity of microfungi associated with decomposing leaf litter of Anacardium occidentale and the pattern of fungal colonization was investigated. Fungi colonizing decomposing litter were induced to sporulate by a moist chamber incubation technique. A total of 77 species belonging to 57 genera were recorded. Depending on the first appearance of the fungi and their persistence, three main groups of fungal colonizers were identified: (1) fungi that occurred initially during early stages of decomposition and disappeared as decomposition progressed; (2) fungi that showed less initial activity but gradually increased their activity and declined in the final stages; (3) fungi that appeared in the late stages of decomposition.

Succession of Microfungi on Leaf Litter of Acacia catechu in Datia, Madhya Pradesh, India

“…After 120 days of decomposition, the numbers of fungal species decreased and were replaced by new colonizers. Findings in present work are similar to that of [32][33][34]19,35,36,20,37,25,24,38 . Occurrence of fungi during succession study on senescent leaves of Mangletia garretti for 56 days recorded 22 fungal taxa with the fungal community composition differing at each stage of succession.…”

Fungi associated with leaf litter of para rubber (Hevea brasiliensis)

“…2., Talaromyces flavus, Cladosporium britanicum, Drechslera heavae and Fusarium semitectum, were recorded only from samples of newly fallen leaves, suggesting that they may be carried over from the phyllophane. Their occurrence on the surfaces of green foliage has been reported previously (Subramanian and Vittal 1980) and they are primary saprobes, which are ever-present inhabitants of aerial plant surfaces (Shanthi and Vittal 2010). Some species of fungi were recorded only on middle stage decaying leaves; for example, Phaeoisariopsis sp.2, Pyriculariopsis parasitica and Scoleobasidium sp.1.…”

“…chemical and physical composition, temperature and aeration during the decomposition process. Succession studies are unclear as to which factor has the greater influence over decomposition rate and fungal diversity (Kannangara and Deshappriya 2005;Osono 2005;Shanthi and Vittal 2010). Promputtha et al (2002) have recorded fungal succession on the leaves of Magnolia garrettii.…”

Oribatid mite communities on the bark of dead wood vary with log type, surrounding forest and regional factors

“…Generally, fungal feeders dominated among oribatid mites suggesting that the most important food resource for oribatid mites on the bark of dead wood are fungi. The results further suggest that fungal feeding species separate into those relying on basidiomycete fungi, e.g., C. femoralis, C. areolatus, C. coriaceus, L. coracinus and Cepheus dentatus, typically occurring in sporocarps of basidiomycetes (Maraun et al, 2014) and from those predominantly feeding on ascomycete fungi, e.g., C. borealis, Eupelops hirtus and Oribatella calcarata, dominating in the litter layer of forests (Visser and Parkinson, 1975;Shanthi and Vittal, 2010).…”
