Pleurotus approximans Pk. — Orient on Baccharis halimijolia; determined by 

 Prof. Dearness. 



Pleurotus niger Schw. — "Note 1 179. Pleurctus niger from Roy Latham, New 

 York. This would have been of much interest to me years ago, 

 when I was working on agarics. I could never understand why 

 I never found Pleurotus niger while the similar little Pleurotus 

 striatulus was so frequent. Pleurotus niger is truly a black 

 plant with black gills and globose, hyaline 4 mic. spores. The 

 gill margins have large white cystidia (or crystals perhaps)."
