Ochrolechia africana

Ciri dan struktur

Ochrolechia africana has a crustose, yellowish-grey to gray thallus with a surface texture ranging from smooth to warted (verruculose or verrucose). The apothecia tend to be under 1.5 mm in diameter, and have thick margins; they are often covered with a "frosty"-looking pruina, although there are forms that lack pruina. The algal layer makes an almost complete layer under the hypothecium, forming abundant but discontinuous clumps. The ascospores measure 43–67 by 18–30 μm. Ochrolechia africana contains several secondary chemicals: the orcinol depsides gyrophoric acid, lecanoric acid, 5-methyl-O-methylhiascic acid, 4,5-di-O-methylhiascic acid, and the xanthone lichexanthone. It is this latter compound that causes the lichen to fluoresce bright yellow when shone with a UV light. The Chinese alpine species Ochrolechia alticola is somewhat similar in appearance to O. africana, but differs in the C+ red reaction of the apothecial margin cortex, the absence of 5-O-methylhiascic acid, as well as its habitat.

Habitat dan peran ekologis

Ochrolechia africana is a widely distributed species, found in tropical and subtropical areas of southern Africa, Asia, Australia, North America, and South America. Reported as new to China in 2013, it is one of about 25 Ochrolechia species known to occur in that country. It typically grows on both the wood and bark of deciduous trees, although it has also been recorded growing on rocks. Irwin Brodo and James Lendemer reported on an atypical population of Ochrolechia africana they found in the Coastal Plain of southeastern North America; these lichens were sorediate and fertile, rather than the typical asorediate and fertile population that was expected.
