Sharma, P.D.2025-04-192025-04-1919733057364https://dl.bhu.ac.in/ir/handle/123456789/108784The mycoflora recorded on the decaying shoots of Setaria glauca, from their early senescence onwards, has been analysed qualitatively. On the basis of time of appearance and sporing and duration periods of fungi, three patterns of colonization have been recognized. The group I members, designated as primary colonists appear on shoots just after their senescence during August. This group includes six dematiaceous hyphomycetes and two sphaeropsidales. These are followed by group II members during the late rainy season, and group III members that appear only for a short period during winter. The dominant forms of group II are, 15 dematiaceous and 3 tuberculariaceous hyphomycetes, 2 sphaeropsidales, and 1 ascomycete, whereas those representing group III are, 27 dematiaceous, 2 moniliaceous and I tuberculariaceous hyphomycetes, 5 sphaeropsidales, 1 melanconiales, and 3 mycelia sterilia.These studies also showed that about 94 per cent of the total mycoflora is constituted by the deuteromycetes of which 12 are sphaeropsidales, 1 melanconiales, 78 moniliales, and 3 mycelia sterilia. The moniliales are represented by 3 species of moniliaceae, 69 of dematiaceae, and 6 of tuberculariaceae. The phycomycete stage was absent, the three mucorales being discovered only by inoculation at an advanced stage of decay. The deuteromycetes, particularly dematiaceous hyphomycetes, have been found to play the most important role in this phase of decomposition. © 1973 OXFORD UNIVERSITY PRESS.Articlehttps://doi.org/10.1093/oxfordjournals.aob.a084673
