Porotrichiim cavifolium Broth, sp. n. Dioicum; robustiusculum, viride, 

 aetate lutescenti-viride, nitidiusculum ; caulis primarius elongatus, caules secun- 

 darii inter se remoti, usque ad 5 cm. longi, brevistipitati, densiuscule foliosi, 

 dense pinnatim ramosi ramis patentibus, infimis usque ad 2 cm. longi, dein 

 descrescentibus, vix complanatis, subpinnatim ramulosis vel simplicibus; folia 

 concavo, stipitis erecto-patentia accrescentia, caulina patentia, oblongo-ligu- 

 lata, obtusissima, apiculata, superne argute et inaequaliter serrata, nervo longe 

 infra apicem folii evanido, cellulis superioribus hexagono-rhombeis, dein sensim 

 longioribus, alaribus sat numerosis, ovalibus, minutis, ramea conformia, sed 

 minora. Caetera ignota. 



Paraguay, sine loco designato (Alfred Russell Wallace, in Herb. Mitten). 



Species ob folia concavo speciebus nonnullus americanis Porolrichodendri, 

 ex. gr. P. superbo similis, sed foliis obtusissimis, superne argute et inaequaliter 

 serratis, cellulis superioribus laxioribus facillime dignoscenda. 



Porothamnium parvirete Broth, sp. n. Dioicum ; gracile, viride, vix nitidius- 

 culum; caulis primarius elongatus, caules secundarii inter se remoti, usque ad 

 5 cm. longi, brevistipitati, densiuscula foliosi, obtusi, raro flagelliformi-attenuati, 

 dense pinnatim ramosi, ramis patentibus, usque ad cm. longis, complanatis, 

 subpinnatim ramulosis vel simplicibus; folio stipitis destructa, caulina sicca 

 indistincte plicatula, humida patentia oblongo-ligulata, obtusissima apiculata, 

 margine inferiore inflexo, superne argute et inaequaliter serrata, nervo longe infra 

 apicem folii evanido, cellulis superioribus minutis, rhombeis, dein sensim longi- 

 oribus, oblongo-hexagonis, basilaribus linearibus, apice papillose exstante, ramea 

 conformia, sed minora. Caetera ignota. 



Paraguay, sine loco designato (Herb. Mitten). 



Species P. porrectulo (C. Miill.) habitu simillima, sed ab hac ut etiam a 

 caeteris speciebus generi cellulis folii superioribus minutis dignoscenda. 



LICHENS OF THE MT. MONADNOCK REGION, N. H.— No. Sf 



Thomas Durfee 



These lichens were determined by the late Dr. H. E. Hasse. All the speci- 

 mens are fertile. 



Genus: Lecanora 

 Section: Aspicilia 



141. Lecanora calcarea (L.) Sommerf. Two specimens, both fertile. 



142. L. cinerea Ach. Eleven specimens, all fertile. 



143. L. laevata (Ach.) Nyl. Two specimens, both fertile. 



* These mosses were sent to Dr. Brotherus to be determined because the collections at the 

 New York Botanical Gardens are not particularly rich in mosses from Paraguay, and there are 

 over 30 species of the genus from S. A. described by various authors, principally Hampe and C. 

 Miiller, which were lacking in Mitten's Herbarium. Specimens of P. cavifolium Broth, n. sp. 

 were probably sent to Alfred Russell Wallace with orchids, as it was his custom to send to his 

 father-in-law, William Mitten, all mosses received in this way.
