Purpose: We aimed to show the increasing incidence of invasive fungal infections due to Volvariella Volvacea in patients with immunosuppression.
Methods: We present a case of an invasive fungal infection caused by Volvariella volvacea, and summarize the clinical and pathological features based on this case and a review of the literature.
Results: A total of seven patients with IFIs due to Volvariella Volvacea have been reported in the literature. The majority of cases have been obtained between 2019 and 2022. Including our case, they all had acquired immunosuppression. The lung and brain were the most commonly affected organs. All eight of these patients received antifungal therapy, but five still died one to seven months after occurrences of IFIs.
Conclusion: The incidence of invasive fungal infections due to Volvariella Volvacea is increasing in recent years. It mainly occurred in patients with immunosuppression, especially in patients with malignant hematological cancers, and increased mortality.

Manganese is one of the trace elements necessary for organisms to maintain normal biological activities and is also a cofactor for manganese superoxide dismutase (Mn-SOD) and manganese peroxidase (MnP). In order to find a simple and effective method to rejuvenate the degenerated strains, we explored the effect of the exogenous addition of MnSO on the antioxidant vigour and productivity of degenerated strains of . The results showed that the exogenous MnSO had no significant effect on the non-degenerated strain T0, but it could effectively increase the mycelial growth rate, mycelial biomass, and LBL decolouring ability of the degenerated strains T10 and T19, and reduce the production cycle and increased the biological efficiency of T10; it helped the severely degenerated T19 to regrow its fruiting body; and it also significantly increased the viability of the matrix-degrading enzymes such as EG, Lac, Xyl, etc.

Degradation of Volvariella volvacea is associated with the accumulation of reactive oxygen species (ROS), and glutathione peroxidase (GPX) is one of the key antioxidant enzyme. The purpose of this research is to uncover the importance of the gpx gene in the degradation and revitalization of V. volvacea.

In the present study, a homogeneous polysaccharide (HVP-2) was isolated and purified from (Chinese mushroom) Volvariella volvacea. The structural characteristics and protective effect of HVP-2 were investigated. The results showed that HVP-2 was composed of mannose, glucose, galactose and arabinose in a molar ratio (mol%) of 59.
