Lichens Of Madagascar
Little work has been done on the lichens of Madagascar, so while over 500 species of lichens have been documented, more are expected. Madagascar can be divided into two major habitats that can be associated with lichen distribution. Wet tropical areas of siliceous bedrock make up approximately two-thirds of the country, and are where most of the lichens have been documented. Dry tropical areas of granitic and limestone bedrock make up the other one-third of the country with just over 20 species documented in these habitats. The following table lists the species known from the dry tropical habitats. The majority are corticolous species that grow on the bark of trees or shrubs. A few are saxicolous; species that grow on rocks. While many of the lichens found to date in Madagascar are relatively widespread, tropical species, some are endemic. ''Isalonactis madagascariensis'', for example, is known only from its type locality near Isalo National Park, and new species continue to be fou ...

Canoparmelia Quintarigera
''Canoparmelia'' is a genus of lichen-forming fungi in the family Parmeliaceae. The widespread genus contains about 35 species. ''Canoparmelia'', a segregate of the parmelioid lichen genus ''Pseudoparmelia'', was circumscription (taxonomy), circumscribed by John Alan Elix, John Elix and Mason Hale in 1986. Description ''Canoparmelia'' lichens have grey or rarely yellow-green thallus, thalli containing the secondary chemicals atranorin and chloroatranorin, or rarely usnic acid, in the cortex (botany), cortex. The thallus is made of more or less rotund lobes that are 3.0–5.0 mm wide and lack cilia; the medulla (lichenology), medulla is white. The underside of the thallus is black or brown with naked brown margins and simple rhizines of the same colour. ''Canoparmelia'' produces small ellipsoid ascospores that measure 10–14 by 6–8 micrometre, μm. The conidium, conidia are fusiform (spindle-shaped) or bifusiform, measuring 7–10 μm long.

Tsimanampetsotsa National Park
Tsimanampetsotsa National Park also spelt Tsimanampetsotse, and known as Tsimanampetsotsa Nature Reserve is a 432 km2 national Park, national park on the south-west coast of Madagascar in the region Atsimo-Andrefana. The park is south of Toliara and south of the capital, Antananarivo. Route Nationales (RN) 10 to Faux Cap passes the park and the nearest airport is at Toliara. The national park contains and is named after Lake Tsimanampetsotsa. History and Significance Tsimanampetsotsa National Park encompasses the westernmost escarpment of the limestone Mahafaly Plateau. It was first protected in 1927 for its endemic flora and fauna and became a national park in 1966. It is within the Madagascar spiny forests or "spiny desert" of southern Madagascar, a globally distinctive ecoregion. This is the area with the highest level of plant endemism in Madagascar, with 48% of the genera and 95% of the species endemicElmqvist T, Pyyko ̈nen M, Tengo ̈M, Rakotondrasoa F, Rabakonandriani ...

Isalo National Park
Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between . History and significance Isalo National Park was created in 1962 and has been administered by the Madagascar National Parks authority since 1997. The Bara people have traditionally inhabited this area, a nomadic people subsisting on cattle (zebu) farming. There are burial sites of the Bara people and some older burial sites of the Sakalava. Isalo is primarily within the dry deciduous forests ecoregion, an ecoregion in which natural vegetation has been reduced by almost 40% of its original extent. It also includes lan ...

Xanthoparmelia Subflabellata
''Xanthoparmelia'' (commonly known as green rock shields or rock-shield lichens) is a genus of foliose lichen in the family Parmeliaceae.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, ''Xanthoparmelia'' is synonymous with ''Almbornia'', ''Neofuscelia'', ''Chondropsis'', ''Namakwa'', ''Paraparmelia'', and ''Xanthomaculina''. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador. The name means 'golden yellow parmelia'. The photobiont (photosynthetic partner) is ''Trebouxia'' (a genus of green algae). Identification Distinguishing between species involves how much they are attached to the substrate, whether or not Isidium, isidia are present, lower surface color, and chemical spot test (lichen), spot tests. All members of the genus react to spot test as K-, KC+ yellow, with medulla (lichenology), medulla reaction varying from species to species. Species Species include: * ''Xanthoparmelia ch ...

Sclerophyton Madagascariense
''Sclerophyton'' is a genus of lichen-forming fungi in the family Opegraphaceae. It has about 15 species.
