“…Notes: Speiropsis is characterized by erect, simple, straight, mostly mononematous conidiophores, polyblastic conidiogenous cells and catenate conidia in branched or unbranched chains connected by narrow isthmi (Barbosa and Gusmao 2005;. Based on morphology and molecular analyses, referred Speiropsis to Wiesneriomycetaceae.…”

“…Genera included in Wiesneriomycetaceae play a role as saprobes, occurring on different substrates with a worldwide distribution (Suetrong et al 2014;Pratibha et al 2015;2016;Crous et al 2016b). In addition, Speiropsis has been reported as an aquatic hyphomycete (Barbosa and Gusmao 2005;Santos 2015 (Ju et al 1996;Jaklitsch et al 2015). There are only three genera with molecular data.…”

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.

“…The genus Speiropsis are possessed with erect, simple, straight, septate, mononematous, aggregates in fascicles or synnematous to sporodochial conidiophores with discrete, denticulate, polyblastic conidiogenous cells and catenate conidia in branched or unbranched chains (Barbosa and Gusmao 2005). S. pedatospora is a mitosporic fungus found in submerged leaves in freshwater bodies (Barbosa and Gusmao 2005) and also a leaf pathogen in Eucalyptus saligna.…”

Phylogenetic Evidence that Two Submerged-Habitat Fungal Species, Speiropsis pedatospora and Xylomyces chlamydosporus, Belong to the Order Jahnulales Insertae Sedis Dothideomycetes

The genera Speiropsis and Xylomyces are anomorph fungi. The taxonomic address for the fungi has been unclear. In this study, observation of morphological traits indicates that they have a unique pattern of mycelia with dark-brown to black colour and thick-walled hyphae. The same culture patterns of certain fungi isolated from freshwater habitats in Thailand were selected from BIOTEC Culture Collection (BCC, Thailand), while more species were added from Centraalbureau voor Schimmelcultures (CBS, Netherlands). These fungi were composed of Jahnula spp. (2-celled ascospores), Brachiosphaera tropicalis (hyaline and 4-5 armed conidia), S. pedatospora (hyaline and branches conidia) and Xylomyces sp. (dematiaceous and fusiform chlamydospores). This study was undertaken to confirm the taxonomic address for S. pedatospora and Xylomyces based on phylogenetics relationships as inferred from their ITS rDNA sequence data by using MP (unweighted and successive weighted MP), NJ, ML and Bayesian analysis. Phylogenic analysis revealed that isolates of S. pedatospora (2 strains) was a member of the Order Jahnulales and clustered with Jahnula spp. (5 strains) and B. tropicalis (4 strains) with >82% bootstrap support and 100% posterior probabilities. Four isolates of X. chlamydosporus, X. elegans and X. aquaticus were shown to be polyphyletic within the Jahnulales and Pleoporales. The MP and NJ showed the same topology as in the Jahnulales clade obtained by ML analysis.

Bezerromycetales and Wiesneriomycetales ord. nov. (class Dothideomycetes), with two novel genera to accommodate endophytic fungi from Brazilian cactus

et al. 2016

During a survey of endophytic fungi from the cactus Tacinga inamoena in a Brazilian tropical dry forest (Caatinga) some undescribed ascomycetous fungi were isolated. These fungi are characterized by superficial and immersed, globose to subglobose, smooth or hairy ascomata, bitunicate asci, and muriformly septate, ellipsoidal ascospores. Multigene phylogenetic analyses using sequences from partial ITS, SSU and LSU nrDNA and the translation elongation factor 1-alpha gene (tef1) demonstrated a monophyletic clade accommodating these endophytic fungi in the class Dothideomycetes, closely related to the order Tubeufiales. Based on morphological features and phylogenetic analyses, these fungi could not be placed in the order Tubeufiales, in the new order Wiesneriomycetales, or any other known genus in the class Dothideomycetes. Thus, two new genera (Bezerromyces, with B. brasiliensis and B. pernambucoensis, and Xiliomyces with X. brasiliensis), a new family (Bezerromycetaceae) and a new order (Bezerromycetales) are introduced to accommodate these novel taxa. Our phylogenetic analyses also demonstrated that the clade accommodating Wiesneriomycetaceae represents a new order, here introduced as Wiesneriomycetales.
