Herre, A. W. C. T., The Lichens of Mt. Rose, Nevada. 

 (The Bot. Gaz. LV. p. 392-396. 1913.) 



This paper contains the enumeration of the species of lichens 

 found on this peak. The most noticeable features of the liehen 

 flora of the mountain are the utter absence of barkdwelling species 

 or those of dead or decorticated wood, and the equally conspicuous 

 absence of earth lichens. 



The enumeration contains one new name: Acarospora thermo- 

 phila n. sp. (this plant was mistakenly called A. thamnina in Bot. 

 Ga2., LI, p. 290, 1911), and a füll description of ^. thamnina (Tuck.) 

 Herre {Lecanora thamnina Tuck.; L. cervina b. thamnina Tuck.).

 p. 496—500. 2 Textfig. 1913.) 



The material has been collected in various localities, mostly on 

 the coast of Alaska, by F. ß. McKechnie. The enumeration 

 does not contain new names, only two new combinations: Lobaria 

 {Sticta) oregana (Tuck.) and Platysma {Cetraria) glaucum var. steno- 

 phyllum (Tuck.) The two illustrations are very valuable as the^^ 

 represent the t^^pe oi ^&\\2iX&\oi Liehen cuciülata [Cetraria ciicnllata 

 [Beil.] Ach.) and the type of Linneus of Liehen nivalis {Cetraria 

 nivalis [L.] Ach). Jongmans.

This paper contains the Synonym}^ and description of the genus 

 Evernia and an enumeration of the species found in North and 

 Middle America. To each species remarks are given on the t5^pe 

 and its history, further one finds a copy ot the original description, 

 a complete new description, the geographical distribution, many 

 remarks on figures and synonymy and observations on variability etc. 



FoUowing species and varieties are mentioned in this paper. 

 Evernia vulpina (L.) Ach., E. prunastri (L.) Ach. and var. thavnnodes 

 Flotow, E. divaricata (L.) Ach., E. fiirfuracea (L.) Mann with var. 

 ceratea (Ach.) Nyl. and E. trulla (Ach.) Mont. The author distinguishes 

 three sections: Letharia Th. Fr. with E. vulpina, Archevernia Th. 

 Fr. with the other species with exception of E. tndla, which is 

 considered as belonging to a new section Euevernia. 



The plates show copies of Dillenius' figures of E. prunastri, 

 E. divaricata and E. furfuracea, figures of Retzius' type oi Liehen 

 arenarius {E. divaricata) and of Acharian types of E. furfuracea 

 and varieties. E. furfuracea var ceratea is illustrated by a specimen 

 collected in Colorado and E. trulla by a specimen in the U. S. 

 National Herbarium. Jongmans.
