Hirsutane-Type Sesquiterpenes with Uncommon Modifications from Three Basidiomycetes
2010
From three basidiomycetes, Xeromphalina sp., Stereum sp., and Pleurocybella porrigens, six triquinane sesquiterpenes with unprecendented modifications and a rearranged sesquiterpene related to coriolin C have been isolated. Their isolation, structure elucidation, and biological evaluation are described.
Sterelactones: New Isolactarane Type Sesquiterpenoids with Antifungal Activity from Stereum sp. IBWF 01060
2008
Four members of a new family of tetracyclic sesquiterenoids possessing the isolactarane skeleton have been isolated from mycelial cultures of Stereum sp. IBWF 01060. Their structure elucidation and their antifungal activity against several plant pathogens as well as other microorganisms are reported.
Sintesi dei dati ecologici e distributivi sul genere Sterum Pers. in Sicilia
2009
Il genere Stereum include basidiomiceti lignicoli saprotrofi o parassiti su legno di latifoglie e conifere (1). I basidiomi crescono su vari substrati legnosi di differenti dimensioni quali rami caduti, tronchi, ceppaie e radici affioranti. La diversità del genere Stereum Pers. in Sicilia è al momento stimabile in cinque taxa: Stereum gausapatum (Fr.) Fr., S. hirsutum (Willd.) Gray, S. rugosum (Pers.) Fr., S. sanguinolentum (Alb. & Schwein.) Fr. (2, 3, 4, 5) e S. subtomentosum Pouzar. I taxa afferenti al genere Stereum possono essere distinti in due gruppi sulla base della colorazione assunta dall’imenio in seguito a taglio o sfregamento: a) imenio arrossante (S. rugosum, S. sanguinolentum …
