“…Index Fungorum (2020) listed K. bambusina as Phyllachora bambusina, hence only the type species is accepted in this genus. Kiehlia is characterized by elongate, immersed stromata and conidiomata growing in a same locule, clavate asci and ovoid, hyaline ascospores with one septum (Viégas 1944). ≡ Hysterostomella alsophilae Racib., Parasit.…”

Refined families of Dothideomycetes: orders and families incertae sedis in Dothideomycetes

et al. 2020

Numerous new taxa and classifications of Dothideomycetes have been published following the last monograph of families of Dothideomycetes in 2013. A recent publication by Honsanan et al. in 2020 expanded information of families in Dothideomycetidae and Pleosporomycetidae with modern classifications. In this paper, we provide a refined updated document on orders and families incertae sedis of Dothideomycetes. Each family is provided with an updated description, notes, including figures to represent the morphology, a list of accepted genera, and economic and ecological significances. We also provide phylogenetic trees for each order. In this study, 31 orders which consist 50 families are assigned as orders incertae sedis in Dothideomycetes, and 41 families are treated as families incertae sedis due to lack of molecular or morphological evidence. The new order, Catinellales, and four new families, Catinellaceae, Morenoinaceae Neobuelliellaceae and Thyrinulaceae are introduced. Seven genera (Neobuelliella, Pseudomicrothyrium, Flagellostrigula, Swinscowia, Macroconstrictolumina, Pseudobogoriella, and Schummia) are introduced. Seven new species (Acrospermum urticae, Bogoriella complexoluminata, Dothiorella ostryae, Dyfrolomyces distoseptatus, Macroconstrictolumina megalateralis, Patellaria microspora, and Pseudomicrothyrium thailandicum) are introduced base on morphology and phylogeny, together with two new records/reports and five new collections from different families. Ninety new combinations are also provided in this paper.

PREMISE OF THE STUDY:Fossils show that fly-speck fungi have been reproducing with small, black thyriothecia on leaf surfaces for ~250 million years. We analyze morphological characters of extant thyriothecial fungi to develop a phylogenetic framework for interpreting fossil taxa. METHODS:We placed 59 extant fly-speck fungi in a phylogeny of 320 Ascomycota using nuclear ribosomal large and small subunit sequences, including newly determined sequences from nine taxa. We reconstructed ancestral character states using BayesTraits and maximum likelihood after coding 11 morphological characters based on original observations and literature.We analyzed the relationships of three previously published Mesozoic fossils using parsimony and our morphological character matrix, constrained by the molecular phylogeny. KEY RESULTS: Thyriothecia evolved convergently in multiple lineages of superficial, leafinhabiting ascomycetes. The radiate and ostiolate scutellum organization is restricted to Dothideomycetes. Scutellum initiation by intercalary septation of a single hypha characterizes Asterinales and Asterotexiales, and initiation by coordinated growth of two or more adjacent hyphae characterizes Aulographaceae (order incertae sedis). Scutella in Microthyriales are initiated apically on a lateral hyphal branch. Patterns of hyphal branching in scutella contribute to distinguishing among orders. Parsimony resolves three fossil taxa as Dothideomycetes; one is further resolved as a member of a Microthyriales-Zeloasperisporiales clade within Dothideomycetes. CONCLUSIONS: This is the most comprehensive systematic study of thyriothecial fungi and their relatives to date. Parsimony analysis of the matrix of character states of modern taxa

“…We only observed immature spores. The description of the mature spores is based on the original description, as follows "ascospores 5-7 septate at maturity, constricted at the septum, smooth to verruculose, thick-walled without a sheath" (Viégas 1944) Material examined: Brazil, São Paulo, Campinas, on leaves of Mikania sp., 5 December 1943, A.P.

One-hundred and sixteen genera are listed as incertae sedis in the class Dothideomycetes. This is a first of a series of papers in which we re-examine the herbarium types of these genera, which are generally poorly known. By examining the generic types we can suggest higher level placements, but more importantly we illustrate the taxa so that they are better understood. In this way the taxa can be recollected, sequenced and placed in a natural taxonomic framework in the Ascomycota. In this study we re-examined the genera Dermatodothella, Dothideopsella, Gloeodiscus, Grandigallia and Hysteropeltella. We re-describe and illustrate the type species of these genera and discuss their placements using modern concepts. Dermatodothella is placed in Polystomellaceae, Dothideopsella in Phaeosphaeriaceae, Grandigallia in Shiraiaceae and Hysteropeltella in Schizothyriaceae, while Gloeodiscus is retained in Dothideomycetes incertae sedis. Fresh collections of these genera are needed for further studies, so that they can be epitypified and molecular data can be analyzed to obtain a natural classification.
