    • Main Results:

    • Two new ceramides, (2S,3R,4E,8E)-N-hexadecanoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol and (2S,3R,4E,8E,9'Z,12'Z)-N-9',12'-octadecadienoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol, were isolated from Panellus serotinus.
    • Additional new ceramides, (2S,2'R,3R,4E,8E)-N-2'-hydroxypentadecanoyl-2-amino-9-methyl-4,8-octadecadiene-1,3-diol and (2S,2'R,3R,4E,8E)-N-2'-hydroxytetradecanoyl-2-amino-9-methyl-4,8-octadeca-diene-1,3-diol, were identified in Amanita pantherina.
    • The presence of known and new ceramide compounds was confirmed across the five investigated mushroom species.

    Conclusions:

    • The chemical investigation successfully identified and characterized novel ceramide structures from mushroom species.
    • This study contributes to the understanding of ceramide diversity in the fungal kingdom.
