Although microbiomes of various compost types have been studied, information is still fragmented and often not tailored to specific raw material combinations. In particular, little is known about the fungal communities involved in composting dairy plant wastewater sludge mixed with garden trimmings. This data paper contributes to filling that gap by providing a comprehensive taxonomic inventory.engThermophiliccooling and maturationgarden trimmingswastewater sludgemicrobiomedata paper10.3897/BDJ.14.e1748931314-2828
