 Title    3',3"'-Binaringenin, a New Biflavonoid from Pilotrichella cuspidata (Meteoriaceae, Musci)  
 Abstract    From Pilotrichella cuspidata the new biflavonoid 3',3"'-binaringenin was isolated. Its struc­ ture was elucidated spectroscopically.

 Title    A M yricetin Tetram ethyl Ether from the L eaf and Stem Surfaces o f Tillandsia usneoides  
 Abstract    Myricetin-3,7,3',4'-tetramethyl ether has been isolated as an aglycone from the acetone wash of Tillandsia usneoides. It is thus shown to be deposited externally, on leaf and stem surfaces. We suggest that the previously re­ ported lipophilic flavonoids from this and other species are also exudate constituents.

 Title    Degradation of Pentachlorophenol by Mycena avenacea TA 8480 - Identification of Initial Dechlorinated Metabolites  
 Abstract    Cultures o f the basidiomycete M ycena avenacea TA 8480 were shown to m etabolize penta­ chlorophenol (PCP), 2,3,5,6-tetrachloro-/7-hydroquinone (TeCHQ), and 2,3,5,6-tetrachloro-/?-benzoquinone (TeCBQ). The first metabolite o f the PCP degradation pathway was identified as TeCBQ which in a second reaction is reduced to the hydroquinone TeCHQ. Subsequently dechlorination o f TeCHQ yielded 3,5,6-trichloro-2-hydroxy-/?-benzoquinone (TCOHBQ). The specific degradation rate for PCP was 1.4 mg x g dry m ycelia-1 x day-1. The initial de­ chlorination rate o f TeCHQ was 5.9 mg x g dry m ycelia"1 x h o u r '1. N one o f the com pounds supported growth o f the fungus.
