Mariannaea Nipponica
''Mariannaea'' is a genus of fungi belonging to the family Nectriaceae. The genus has cosmopolitan distribution. The fungal genus was formally established by Samson (1974) to accommodate ''M. camptospora'', ''M. elegans'' and the variety ''M. elegans'' var. ''punicea'' and was typified by ''M. elegans''. The genus is characterized by branched, septate conidiophores with hyaline, flask-shaped phialides, 1–2-celled hyaline conidia mostly forming imbricate chains or slimy heads (Samson 1974; Samson and Bigg 1988; Samuels and Seifert 1991). The sexual morph of ''Mariannaea'' has been linked to genus ''Nectria'' (Samuels and Seifert 1991), and genus ''Cosmospora'' (Gräfenhan et al. 2011). However, ''Cosmospora'' and ''Nectria'' have been shown polyphyletic within the Nectriaceae family, while genus ''Mariannaea'' formed a monophyletic clade within Nectriaceae. Therefore, Gräfenhan et al. (2011) retained ''Mariannaea'' as a distinct genus in Nectriaceae. Five new species were fur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariannaea Elegans
''Mariannaea elegans'' an anamorphic fungus (i.e., it reproduces exclusively asexually). It is mainly found on rotting wood and soil. ''M. elegans'' is not pathogenic to humans, animals, or plants. History and taxonomy Czech mycologist August Carl Joseph Corda named this species ''Penicillium elegans'' in 1838. This species was transferred to the genus ''Paecilomyces'' in 1951. Later, in 1952, French mycologist, Gabriel Arnaud named the species ''Mariannaea elegans'' although he failed to provide a Latin description, which was a requirement for valid publication at the time. Arnaud noted that the genus ''Mariannaea'' shared many characteristics with genus ''Paecilomyces'' but was distinguished by the divergent nature of the conidial chains of ''Mariannaea''. This conclusion was supported by Dutch mycologist, Robert Archibald Samson, who in 1974 validated the names of the genus and species by providing Latin diagnoses. The genus ''Mariannaea'' currently consists of eight species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
