Savoronala
''Savoronala'' is a fungal genus in the family Malmideaceae. It is monotypic, containing the single species ''Savoronala madagascariensis''. This lichen produces unique conidia (asexual spores) that each include a single algal cell. Taxonomy Both the genus and the specie were described as new in 2013 by Damian Ertz, Eberhard Fischer, Dorothee Killmann, Tahina Razafindrahaja, and Emmanuël Sérusiaux. The type specimen was collected in Tôlanaro, Madagascar, in a coastal ''Erica''-grassland. It was found growing on the stem of an ''Erica'' shrub. The lichen is known only from the type locality. The area it was collected from is under pressure because of habitat destruction, charcoal production, and a nearby giant mine of ilmenite. Molecular phylogenetic analysis showed ''Savoronala'' be part of Malmideaceae, a family circumscribed in 2011. Description Several features characterize the genus ''Savoronala''. It produces small thalli that are pale glaucous and placodioid (crustos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malmideaceae
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species. Taxonomy Malmideaceae was created in 2011 to accommodate a group of species, formerly placed in genus '' Malcolmiella'' (family Pilocarpaceae), that molecular phylogenetics showed to be a distinct lineage and worthy of recognition at the family level. The genus ''Savoronala'', containing the single African species '' S. madagascariensis'', was added to the family in 2013, while another monotypic genus ''Kalbionora'' was added in 2017. Description Malmideaceae is similar to Pilocarpaceae, but can be distinguished from that family by thallus organization and ascus structure. ''Malmidea'' species have a thallus made of goniocysts–spherical aggregations of photobiont cells surrounded by short-celled hyphae. This characteristic is quite rare in the Pilocarpaceae, only found in the monotypic genera ''Calopadiopsis'' and ''Pseudocalopadia''. Des ...
