An ascomycete with non stromatic, narrowly ovoidal or subpyriform, pale yellow to luteous perithecia, a Nectria-like centrum, yellowish-brown reticulate ascospores, and a Trichothecium-like anamorph has been isolated from small rodent dung in Italy. Based on morphological, cultural and molecular (nrLSU and ITS sequences) data, a new genus, Rodentomyces, and a new species, R. reticulatus, are therefore introduced to accommodate this fungus. Rodentomyces represents a hypocrealean genus in the Nectriaceae. Within this family, and based on molecular data, R. reticulatus is placed in the group including Calonectria, Leuconectria, Nectricladiella, Neonectria and Nectria mariannaeae. Several coprophilous genera are recorded in Hypocreales almost evenly distributed among the main families of this order

“…As to nectriaceous fungi, small-sized perithecia and a Cosmospora-like perithecial wall structure are common in several genera like Chaetopsinectria, Cosmospora, Cyanonectria, Nectricladiella, Pseudonectria, Volutellonectria, etc. (Rossman et al 1999, Schoch et al 2000, Samuels et al 2009, Luo and Zhuang 2010b. It is clear that teleomorphic morphology alone provides insufficient information to outline a genus within these fungi.…”

“…Fungal genomic DNA was extracted using the protocol of Wang and Zhuang (2004). ITS1-5.8S-ITS2 (ITS) and partial 28S nuclear ribosomal DNA were used to solve the phylogenetic problems of selected genera of nectriaceous fungi (Schoch et al 2000, Crous et al 2005, Samuels et al 2009, 2010b, Zhao et al 2011. PCR amplification and sequencing of complete ITS and partial 28S nrDNA were conducted with the methods described by Luo and Zhuang (2010b).…”

Volutellonectria (Ascomycota, Fungi), a new genus with Volutella anamorphs

2012

View full text Add to dashboard Cite

A new genus, Volutellonectria with Volutella anamorphs is established, based on and typified by Cosmospora consors. It is characterized by small, red perithecia which may collapse laterally when dry, a Cosmospora-like perithecial wall structure, clavate asci with an apical ring, fusiform ascospores with smooth surface, and growing on decaying plant debris or woody substrates. Two new species are added to the new genus and described as Volutellonectria asiana and V. ciliata. Phylogenetic analyses of nuclear ribosomal DNA (ITS and 28S partial) strongly support the separation of Volutellonectria from Cosmospora and some other species with Volutella anamorphs in Nectriaceae, as well as recognition of the new species.

“…They occur more commonly in tropical and subtropical regions, while temperate climates are also favorable for some members of the group. On the basis of ascomatal color and reactions to KOH aqueous solution and lactic acid, they were assigned to two families, Nectriaceae and Bionectriaceae [1][2][3][4].…”

Four new species belonging to Bionectria, Calonectria, Haematonectria and Neonectria on plant substrates collected from nature reserves in southern and central China are described. Bionectria truncata has smooth perithecia of a flattened to shallow discoid apex, clavate asci with an apical ring, and ellipsoid, smooth to spinulose ascospores. Calonectria dicephalospora is characterized by pyriform perithecia with a warted surface, clavate asci with a simple apex and long, narrow stalk, and fusoid ascospores with a cap-like appendage at each end. Haematonectria lushanensis possesses warted perithecia which are laterally collapsing when dry, cylindrical asci with a simple apex, and ellipsoid, spinulose ascospores. Neonectria dinghushanica is distinguishable by subglobose perithecia with a warted surface, clavate asci, and striate ascospores. Morphological features of these new species are described comprehensively and compared with their related fungi. Neonectria castaneicola is recorded as new to China.
