Dendriscosticta<br />
Peltigerales Lobariaceae<br />
5<br />
Dendriscosticta is more or less a northern Hemisphere genus newly described by<br />
Moncada et. al in 2013. This is macr<strong>of</strong>oliose (with very large lobes) genus, grows<br />
epiphytically, or very rarely on mossy rocks or logs, <strong>of</strong>ten between bryophytes<br />
and other lichens.<br />
The presence <strong>of</strong> cyphellae-like pores (cyphelloids) that are white and abundant<br />
on the lower surface distinguishes Dendriscosticta from the closely related<br />
Lobaria, Sticta and Pseudocyphellaria. However, <strong>Sri</strong> <strong>Lanka</strong>n species need thorough<br />
morphological, chemical and molecular analysis. Especially the species placed<br />
in genus Lobaria in <strong>Sri</strong> <strong>Lanka</strong> need to be thoroughly studied to understand<br />
whether they belong to genus Dendriscosticta. Further, it is possible that more<br />
species could occur in the highlands which would have been overlooked as<br />
Lobaria in montane communities which have not yet been fully observed.<br />
Apothecia cup shape and lecanorine; Spores: acicular to fusiform, septate and<br />
hyaline.<br />
Chemistry No substance detected on <strong>Sri</strong> <strong>Lanka</strong>n material.<br />

Lobariaceae<br />
Description This macr<strong>of</strong>oliose lichen becomes pale brownish to green grey<br />
when dry and yellowish green when wet. It is loosely attached, mostly found<br />
among other mosses and epiphytes. The individual lobes have irregular to round<br />
apices, with more rounded margins. Branches are irregular and form thallus<br />
rosettes. The lower surface is pale brown. Cyphellae- like pores are present<br />
(cyphelloids). Isidia or soredia were not observed. Apothecia were not observed<br />
in <strong>Sri</strong> <strong>Lanka</strong>n material.<br />
Lobariaceae<br />
Status This very rare species is a new record for this new genus from <strong>Sri</strong><br />
<strong>Lanka</strong>. So far only one species belonging to this genus is known in <strong>Sri</strong> <strong>Lanka</strong>. This<br />
species was first reported by D.D. Awasthi (2007) from India and Nepal.<br />
Habitat Mostly seen in humid, high elevation forest areas, sitting on high<br />
elevation montane forests. When the thallus is young, it is not easy to spot<br />
among mosses.<br />
Locations Knuckles mountain region. Only seen in a few sites <strong>of</strong>f Kalupahana.<br />
