“…A series of sesquiterpene orsellinates has been isolated and characterized from cultures of Armillaria mellea and A . ostoyae (Donnelly et al, 1982(Donnelly et al, , 1984Medland et al, 1982), and orsellinic acid itself is reported to exhibit antibacterial and antifungal activity (Lennartz, 1947 ;Fujikawa et al, 1956 ;Cwielong, 1986). Although inhibition of other fungi by S. crispa may be due to the effects of these compounds, and growth of Heterobasidion annosum, which is strongly inhibited by S. crispa on agar plates, was reduced by purified ScI and ScII, the data available are insufficient for proof.…”

The basidiomycete fungus Sparassis crispa produced three antifungal compounds during submerged culture in 2 % malt broth. One compound appeared to be sparassol (methyl-2-hydroxy-4-methoxy-6-methylbenzoate), first characterized in 1924. The other two, termed ScI and ScII, exhibited considerably greater antifungal activity than did sparassol against Cladosporiurn cucurnerinurn, and were characterized as methyl-2,4-dihydroxy-6-methylbenzoate (methyl orsellinate) and an incompletely determined methyl-dihydroxy-methoxy-methylbenzoate, respectively. Both compounds were found in the decayed wood of trees, where their presence was diagnostic of S. crispa infection. The possible ecological role of these compounds is discussed.

We found that in the presence of host plant cells or some antagonistic fungi, the highly forest-pathogenic basidiomycete Awn7/0n'o ostoyae is strongly stimulated to produce a series of toxic secondary metabolites which are capable of inhibiting the growth of the antagonist or of killing the plant cells still before cell contact. The chemical structures of the metabolites have been identified, of which two of them are new compounds. The time dependence and sites of synthesis in the mycelium have been determined in order to lay the foundation for future studies concerning the induction mechanism for the synthesis of the toxins. Sekundäre Püzmetabolite und ihre biologische Aktivität, II. Vorkommen antibiotischer Verbindungen in Kulturen von Armillaria ostoyae, die in Gegenwart von antagonistischen Pilzen oder von Pflanzenzellen gebildet werdenZusammenfassung: Wir fanden, daß in dem stark pathogenen Basidiomyceten Armillaria ostoyae bereits vor der Infektion einer Wirtspflanze, aber auch in Gegenwart antagonistischer Pilze die Synthese einer Reihe toxischer Sekundärmetabolite stark stimuliert wird. Unter diesen Metaboliten wurden zwei neue Verbindungen identifiziert. Der Mechanismus der Induktion der Toxinsynthesen ist unbekannt. Um für diesbezügliche künftige Arbeiten die notwendigen Grundlagen zu schaffen, wurde der Zeitverlauf ihrer Bildung gemessen und die Bereiche im Mycel lokalisiert, in denen die Toxine vermehrt gebildet werden.
