Importance and role

Importance of genus to ecosystem

Species of Anisomeridium are lichenized and able of supporting photosynthesis (Will-wolf et al. 2004).

 

Industrial relevance and applications

The industrial use of Anisomeridium has not been investigated.

 

Quarantine significance

No disease has been reported from Anisomeridium.

 

Biochemical importance of the genus, chemical diversity or applications

The chemical diversity of Anisomeridium has not been investigated.

 

Diversity of the genus

Although there are 46 Anisomeridium epithets in Index fungorum, the real number of species is less as several species have been synonymized and transferred to other genera such as Anisomeridium, Megalotremis and Pleurotrema. Anisomeridium comprises 60 species known on wide range of plants such as on deeply shaded semi-aquatic and aquatic rhyolite, on bark, lime plaster, on leaves of Raphia (Arecaceae) in rainforest, smooth bark in undisturbed forest, living branch of Andromeda ligustrina (Ericaceae), leaves in lowland rain-forest, lateritic rock in primary rainforest and Musci (Pottiaceae). Anisomeridium is reported from Assam, Costa Rica, Ivory Coast, Madeira, New Jersey, New South Wales, Rondônia, Sergipe, South Australia and Uttar Pradesh. Anisomeridium seems to be a diverse genus and may comprise many more species. Several species which lack molecular data might not belong to the genus hence those species need to be revised to provide a stable taxonomy of Anisomeridium.
