Lecanora species (Lecanoraceae, Ascomycota) containing atranorin in Europe.
Xanthomendoza galericulata, a new sorediate
lichen species, with notes on similar spccies in North America.
Undersurface black, lustrous, smooth to rugose or papillate only at some points; marginal zone brown, usually light brown or beige under the sorediate
lobes, lustrous, 1-6 mm wide, naked, with sharp to more often attenuated limit, smooth, rugose, or papillate; rhizines black, simple, sometimes joining adjacent rhizines when touching the substrate, 0.2-0.5 x 0.05-0.10 mm, few, distributed in groups.
New records of sorediate
species of Parmotrema with protocetraric acid (Ascomycota, Parmeliaceae) from southern South America.
Piercey-Normore (2006) similarly found a large number of Trebouxia genotypes in the sorediate
Evernia mesomorpha collected from mixed deciduous--coniferous forest in Canada.
A new perspective on the sorediate
Punctelia (Parmeliaceae) species of North America.
This is a sorediate
, lobate, yellowish-orange species of exposed calcareous substrates, particularly in southwestern North America.
islandica is not sorediate
. Its phylogenetic relationships are unknown to date but it probably belongs to the "supergroup" Cladonia of Stenroos et al.
Apothecia immersed when young, then sessile, scattered, 0.5-1.55 mm diam.; disc dark scarlet to cinnabar-red with the color penetrating into the margin, epruinose, thalline margin thin, appearing almost granular to sorediate
, evanescent with age.
Photobiont chlorococcoid; thallus green, granulose-leprose, entirely sorediate
; apothecia [+ or -] round, blue-gray, pruinose; spores 3-(5) septate.
A characteristic species with scyphose podetia coarsely sorediate
in the upper part, sometimes considered a chemotype of C.
This species has been recorded from China by Guo (1999), but his records need confirmation, especially because there is a another, very similar, sorediate
, species C.
