“…Mariannaea superimposita can easily be differentiated from the new species as it produced much larger and 2-celled conidia (Samuels and Seifert 1991). Other Mariannaea species such as M. clavispora and M. nipponica can be differentiated from M. aquaticola by their clavate conidia in straight chains, rather than ellipsoidal to fusiform conidia in imbricate chains in M. aquaticola (Samson and Bigg 1988;Matsushima 1995). Mariannaea clavispora and M. nipponica were somewhat atypical of Mariannaea as they do not produce imbricate conidial chains.…”

“…This brings the total to five species, with one of the species comprising two varieties. The first and only teleomorph connection of Mariannaea was established by Samuels and Seifert (1991) to Nectria. Mariannaea species are mostly known as colonizers of wood, bark, pine needle, nematode cyst, and fruiting body of basidiomycetes, or occur in soils, and are also known from diseased roots (Samson 1974;Samson and Bigg 1988;Samuels and Seifert 1991;Matsushima 1989;Carris et al 1989;Tokumasu et al 1990;1994;Schroers et al 2005;Castañeda Ruíz et al 2009). In this paper, we describe a new species of Mariannaea from submerged wood in freshwater streams.…”

Mariannaea aquaticola sp. nov. is described, illustrated, and compared with closely related taxa. Phylogenetic analysis of rDNA ITS and 28S sequences show that Mariannaea aquaticola has affinity with Nectriaceae, which is in agreement with other Mariannaea species.Other morphologically similar genera such as Verticillium and Clonostachys are shown to be phylogenetically distant to Mariannaea. The generic concept of Mariannaea is discussed, and the affinity to Nectriaceous teleomorphs is suggested as additional generic character. A key to Mariannaea species is provided.

New Record of Mariannaea elegans var. elegans in Korea

A Mariannaea fungus was isolated during investigation of an elm tree infested with unidentified beetles. Based on morphological characteristics and molecular analysis of the internal transcribed spacer rDNA sequence, the fungus was identified as Mariannaea elegans var. elegans. Fungal growth was better on malt extract agar than on potato dextrose agar and oatmeal agar. Optimal temperature and pH for growth of the fungus were 30℃ and pH 7.0, respectively. The fungus was found to have the ability to produce extracellular enzymes such as amylase, β-glucosidase, cellulase, and protease. This is first report on M. elegans var. elegans in Korea.

“…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 Nectria (Samuels and Seifert 1991) and Cosmospora (Gräfenhan et al 2011) GenBank numbers: ITS = OP876732, LSU = OP875086.…”

Hypocreomycetidae is a highly diverse group with species from various habitats. This subclass has been reported as pathogenic, endophytic, parasitic, saprobic, fungicolous, lichenicolous, algicolous, coprophilous and insect fungi from aquatic and terrestrial habitats. In this study, we focused on freshwater fungi of Hypocreomycetidae which resulted 41 fresh collections from China and Thailand. Based on morphological and phylogenetic analyses, we identified 26 species that belong to two orders (Hypocreales and Microascales) and six families (Bionectriaceae, Halosphaeriaceae, Microascaceae, Nectriaceae, Sarocladiaceae and Stachybotryaceae). Ten new species and 13 new habitats and geographic records are introduced. Mariannaea superimposita, Stachybotrys chartarum and S. chlorohalonatus are recollected from freshwater habitats in China. Based on phylogenetic analysis of combined LSU, ITS, SSU, rpb2 and tef1-α sequences data, Emericellopsis is transferred to Hypocreales genera incertae sedis; Pseudoacremonium is transferred to Bionectriaceae; Sedecimiella is placed in Nectriaceae; Nautosphaeria and Tubakiella are excluded from Halosphaeriaceae and placed in Microascales genera incertae sedis; and Faurelina is excluded from Hypocreomycetidae. Varicosporella is placed under Atractium as a synonym of Atractium instead of Varicosporella. In addition, phylogenetic analysis and divergence time estimates showed that Ascocodina, Campylospora, Cornuvesica and Xenodactylariaceae form distinct lineages in Hypocreomycetidae and they evolved in the family/order time frame. Hence, a new order (Xenodactylariales) and three new families (Ascocodinaceae, Campylosporaceae, and Cornuvesicaceae) are introduced based on phylogenetic analysis, divergence time estimations and morphological characters. Ancestral character state analysis is performed for different habitats of Hypocreomycetidae including freshwater, marine and terrestrial taxa. The result indicates that marine and freshwater fungi evolved independently from terrestrial ancestors. The results further support those early diverging clades of this subclass, mostly comprising terrestrial taxa and freshwater and marine taxa have been secondarily derived, while the crown clade (Nectriaceae) is represented in all three habitats. The evolution of various morphological adaptations towards their habitual changes are also been discussed.
