The organic solvent extraction of Armillaria mellea showed different highly
intrinsic fluorescent compounds either in rhizomorph or in hyphae (F , F , F ,
MF , MF and MF ). The characterization of ultraviolet and fluoro-spectrophotometry
of these compounds has been exhibited. Thin layer chromatography
and fluorescent spectrum of hyphae and rhizomorph indicated an additional
compound (FH) in hyphae. The compound probably plays a role in differentiation
from hyphae to rhizomorph
