Metatrichia vesparium

From the myxomycete of the same genus, Metatrichia vesparium, vesparione (40), a naphtha[2,3-b]pyrandione derivative was isolated as a red pigment of its fruit bodies, and this compound exhibited antibiotic properties [21]. 

Fruits of Trichia floriformis, Metatrichia vesparium (Myxomycetes) [61], Tectona grandis (Verbenaceae) [46]. Biological effect cytotoxic [46]. 

From the slime mold Metatrichia vesparium (Myximycetes), a red pigment, vesparion (353), was isolated and its structure was established from spectroscopic data and by synthesis (87LA793). 

Fruit bodies of the slime mould Metatrichia vesparium contain homo trichione (386) as the major pigment along with the arcyriaflavins-B and -C (see Section 5.3), and minor amounts of vesparione (387) and trichione (280) 436, 438). The structure of homotrichione (386) followed from the spectroscopic data and by comparison with trichione...
