LICHENS OF THE VICINITY OF LOS 

 ANGELES.— IV. 

 By Dr. H. E. Hasse. 



Acolium Bolanderi, Tuckerm. On rocks. (In relation to 

 Acolium Bolandei'i, Tuckerm., Dr. Stizenberger wrote Sept. 

 27, 1894; — " a true Acolium Bolanderi, but here Tuckermann 

 committed a gross mistake as did before him Koerber and 

 Hepp (likewise Fee the elder) with similar structures. They 

 looked upon parasitic Hyphomycetes as Caliciaceae. We 

 have here before us a rust-fungus on the thallus of Binodina 

 angelica, Stiz. !!" — and again on Dec. 2, 1894; — ''Acolium 

 Bolanderi, Tuckerm., is a Uredo-like fungus and not a 

 lichen.")
