Howe: American Species of Alectoria

. . . nigris.' Ad corticem arborum in Monterey Californiae 

 (Menzies). Specimen nullum vidi, et sine analysi dubium est an 

 hujus sit loci species Tuckermaniana. Apothecia ' appendiculata ' 

 nigra genus aliud indigitare videntur." 



In 1872 (Gen. Lich. 9), Tuckerman writes " C. calif omica, 

 Tuckerm." . . . "a tree-lichen, discovered by Menzies, and look- 

 ing often rather like a discoloured, small form of Ramalina cali- 

 caris, but in fact comparable, as respects the thallus, with Cetra- 

 ria aculeata, and, especially as respects the apothecia, with C. 

 tristis, proves also to agree with the latter in its spermogones and 

 spermatia; and constitutes therefore a very interesting addition 

 to our scanty material for the final determination of the place of 

 C. tristis/' 



After ten years, in 1882 (Synop. 29), Tuckerman again lists 

 the species, describing it as follows : " thallus tufted, fruticulose, 

 erect, cartilagineous, subfistulous, compressed-terete, at length 

 deeply- and canaliculate-lacunose dichotomously much- and 

 spread-branched ; greenish olivaceous, fuscescent, dull ; apo- 

 thecia sub-terminal, middling-sized, appendiculate, the disk dark- 

 green, becoming convex and black, and excluding the toothed 

 margin. Spores ellipsoid ~ mic. — Spermogones immersed-papil- 

 lae-form; spermatia oblong, thickened at each end -0^ mic." It 

 will be noticed that the most important additions are the words 

 " compressed-terete." He writes also " Fences, Oregon, Hall. 

 British Columbia, Macoun. Most naturally associable with the 

 genus which shall include C. aculeata; but agreeing in the spermo- 

 gones and their contents with C. tristis/' 



In 1888, Nylander received from Dr. J. W. Eckfeldt* actual 

 material collected on Pinus contorta in Oregon and described it 

 as a new species (Enum. Lich. Freti. Behringii, Bull. Soc. Linn. 

 Normandie, Caen 1: (4) 270) of Alectoria as A. cetrariza. His 

 specific name curiously enough hinted at Tuckerman's original 

 generic distribution, as we now realize that he was renaming the 

 Menzies' plant, though, so far as we know, he did not recognize 

 it as the plant fitting Tuckerman's description which he had 

 quoted. Nylander described it as follows : " Thallus castaneo-
