Huhndorf}, title = {Multigene phylogeny of the Coronophorales: morphology and new species in the order}, year = {2010}, keywords = {}, doi = {10.3852/09-043}, url = {}, pmid = {}, journal = {Mycologia}, volume = {102}, number = {1}, pages = {185--210}, abstract = {The phylogenetic relationships within Coronophorales have long been debated because of uncertainty over the level of taxonomic usefulness of the distinguishing characterisitics such as quellk?rper, number of ascospores per ascus, presence of ascospore appendages, presence of subiculum, and ascomatal vestiture. The phylogenetic relationships within Coronophorales are examined using DNA sequence data from three nuclear genes targeting 69 taxa representing new collections from Africa, North, South and Central America and resulting in 130 new sequences. The analyses recovered monophyletic Bertiaceae, Chaetosphaerellaceae, and Scortechiniaceae and confirmed a paraphyletic Nitschkiaceae. A single collection of Coronophora gregaria is included and Coronophoraceae is accepted for the genus. The concept of Bertiaceae is expanded to include Gaillardiella and Thaxteria is synonymized with Bertia with a new combination, B. didyma. Three new species of Bertia are described: B. ngongensis from Kenya, B. orbis from Kenya and Costa Rica and B. triseptata from Ecuador and Puerto Rico. Bertia gigantospora is transferred from Nitschkia. Scortechiniaceae is confirmed for the quellk?rper bearing taxa including the monotypic genera Biciliospora, Coronophorella, Neofracchiaea, Scortechiniella and Scortechiniellopsis, each represented by single collections. Tympanopsis is reinstated for T. confertula and T. uniseriata while Scortechinia is more narrowly circumscribed to include S. acanthostroma and the new species, S. diminuspora from Ecuador. Cryptosphaerella is accepted in Scortechiniaceae including six new species from Kenya and Costa Rica, C. celata, C. costaricensis, C. cylindriformis, C. elliptica, C. globosa, and C. malindensis. Spinulosphaeria is accepted in Coronophorales with uncertain family placement. The number of ascospores in the ascus is not phylogenetically useful in distinguishing genera within the order. The quellk?rper continues to be an important character in defining the Scortechiniaceae, while taxa within the group show a mixture of morphological characteristics of varying phylogenetic importance. The presence of smooth versus spinulose subiculum aids in separating Tympanopsis and Scortechinia and erumpent ascomata distinguish Cryptosphaerella species. Taxa within the Bertiaceae vary along the lines of robust, tuberculate, collapsing ascomata and hyaline to pigmented, septate ascospores mostly larger than in other taxa in the order.} }
