Mycologia 



Type locality: Sheopore, East Indies, Wallick, January, 1821. 



Original description : " thallo pendulo, elongato, filiformi, 

 tereti-compresso, subdichotomo, implexo, pallide virenti, hinc 

 canaliculato, ad angulos compresso, ramulis ultimis setaceis, flexu- 

 oso-curvatis, apice nigricantibus ; gemmis in thalli canaliculo pul- 

 veraceis, concoloribus ; apotheciis minutis, convexis, fuscis, 

 immarginatis," Hook. Jour. Bot. 6 : 188. 1847. 



Diagnosis : Thallus pendulous, pliant, sulpho-virescent, 

 branches subterete, dull, tortulous. 



Description : Thallus pendulous, pliant, branches subterete to 

 compressed, tortulous, sulpho-virescent (more or less washed with 

 brown) ; cortex dull, sparingly striate (in the type longitudinally 

 split) ; primary branches subremotely dichotomous, more or less 

 tortulous (max. length 20 cm.) ; secondary branches dichotomous, 

 somewhat tortulous ; fibrils capillaceous, terete. Apothecia not 

 observed. 



Substrata : On trees. 



Geographical distribution : Shores and islands of the strait 

 of Georgia, British Columbia and Puget sound, Washington; 

 also atypical examples examined from Silverton, Oregon, and 

 Goldendale, Washington. 



Observations : This plant is poorly represented in our area. 

 Though Taylor's original description included the apothecia, the 

 type is sterile, and according to Hue the apothecia are unknown. 

 Mr. G. K. Merrill described our virescent examples as belonging 

 to a new species, differentiating it from virens on the ground of 

 its tortulous branches. As a tortulous condition is characteristic 

 of a number of the pendulous Alectorias, as well as being true of 

 the type of virens, our examples, if recognized as distinct, must be 

 referred to this species of Taylor with which they are closely 

 comparable. Seeming intergrades, • however, occur with jubata 

 through implexa, and only more material not now available can 

 decide its true relationship. I cannot help doubting in this light 

 Miiller's attributed affinity.
