Ramalina alludens Nyl. 
Synonymy: Ramalina alludens Nyl., Recog. mono. Ram. 130 [32]. 1870.

Ramalina canaliculata Tayl * fide Mull. Arg. 
Type: In the Nylander herbarium, Universitetets Botaniska Institution, 
Helsingfors, fide author. 
Type locality: “Orizabae” Mexico. Fr. Muller. 
Original description: “Thallus osseo-pallidus, compressus, lineari-atten- 
uatus (latit. 1 millim. vel majis attenuatus, altit. circiter 9-12 centimetr.), 
canaliculatus, caespitose congestus, parum ramosus, apicibus longe accuminatis; 
apothecia carnea pallida vel carneo-glaucescentia, mediocria (latit. circiter 2-4 
millim.), calcaria, marginalia, receptaculo subtus laevi vel obsolete ruguloso et 
basi breviter constricto; sporae fusiformes curvulae (vel subrectae). longit. 
0.020-35 millim., crassit. 0.0045-0.0055 millim.” 1. c. 
Figure: PL XIII, /. 1. 
Observations: This species is apparently confined to Mexico. It seems 
probably indistinguishable from R. canaliculata Tayl. The title alludens it 
seems well to retain in view of the present binomial R. canaliculata (Fr.) Herre, 
though the Taylor name has a binomial priority over that of Fries. It would 
seem closely allied to R. linearis except for its fusiform spores. I have seen it 
from Oaxaca Mt., 9000 ft.

Type: In the Nylander herbarium, Universitetets Botaniska Institution,

Type locality: “California” ex hb. Lenorm, Caen. 
Original description: “Thallus stramineo-pallidus compressus sublineari- 
laciniatus subcanaliculatus, nonnihil nervoso-inaequalis vel sublaevis minor 
(altit. circiter 2 centimetr., latit. circiter 2 millim.), ramis utrinque attenuato- 
ramulosis (laciniolis patentibus attenuato-acutis) ; apothecia carneo-testacea 
(subpruinosa), terminalia vel subterminalia (latit. 1-4 millim.), demum convexa, 
receptaculo basi plicato contricto (plicis sub eodem sensim versus marginem ob- 
literate); sporae fusiformi-oblongae bistortae (scilicet utroque apice sensu 
contrario nonnihil tortae septoque saepius obliquo), longit. 0.012-16 millim., 
crassit. 0.006 millim.” 1. c. 
Figure: PL XII, f. 3. 
Observations: This Nylander species, distinct -on account of its spores, 
I have seen from Jamaica, as well as the Californian type. I can add nothing 
further to its history.
