Differential sensitivities to the cell wall stress caused by Congo red (CR) have been observed in many fungal species. In this study, the tolerances and sensitivities to CR was studied with an assorted collection of fungal species from three phylogenetic classes: Sordariomycetes, Dothideomycetes, and Eurotiomycetes, three orders, and eight families. These grouped into different ecological niches, such as insect pathogens, plant pathogens, saprotrophs, and mycoparasitics. The saprotroph Aspergillus niger and the mycoparasite Trichoderma atroviride stood out as the most resistant species to cell wall stress caused by CR, followed by the plant pathogenic fungi, a mycoparasite, and other saprotrophs. The insect pathogens had low tolerance to CR. The insect pathogens Metarhizium acridum and Cordyceps fumosorosea were the most sensitive to CR. In conclusion, Congo red tolerance may reflect ecological niche, accordingly, the tolerances of the fungal species to Congo red were closely aligned with their ecology.

在许多真菌物种中观察到对由刚果红 (CR) 引起的细胞壁应力的不同敏感性。在这项研究中，对 CR 的耐受性和敏感性研究了来自三个系统发育类别的各种真菌物种：Sordariomycetes、Dothideomycetes 和 Eurotiomycetes，三个目和八个科。这些分为不同的生态位，如昆虫病原体、植物病原体、腐生菌和真菌寄生。腐生菌Aspergillus niger和支原体Trichoderma atroviride作为对 CR 引起的细胞壁应激最具抵抗力的物种脱颖而出，其次是植物病原真菌、支原体和其他腐生菌。昆虫病原体对CR的耐受性低。昆虫病原体绿僵菌和冬虫夏草对 CR 最敏感。总之，刚果红耐受性可能反映了生态位，因此，真菌物种对刚果红的耐受性与其生态密切相关。
