“…Several morphological characters of the present fungus, such as perithecioid ascomata, cellular pseudoparaphyses, bitunicate asci, and asymmetrical ascospores, indicated that it belongs to the Pleosporales (Barr and Huhndorf 2001). However, we have been unable to find an appropriate genus to accommodate it by reviewing the literature on bitunicate ascomycetes (e.g., von Arx and Müller 1975;Barr 1987;Eriksson 1981;Luttrel 1973;Sivanesan 1984) and didymosporous or apiosporous ascomycetes (e.g., Hyde et al 1998;Müller and von Arx 1962).…”

A new genus, Katumotoa, is established for a single species, K. bambusicola, collected from culms of Sasa kurilensis. Morphological differences between Katumotoa and some related genera are noted. Katumotoa is characterized by perithecioid ascomata, thin ascomal wall composed of small pseudoparenchymatous cells, cellular pseudoparaphyses, fissitunicate asci, and apiosporous fusiform ascospores with bipolar mucilaginous sheath. From these features, it is considered that the genus belongs to Phaeosphaeriaceae in Pleosporales.

“…The monophyletic nature of the Asterinaceae clade might suggest the reestablishment of the order Asterinales as proposed by Barr (1976Barr ( , 1979Barr ( , 1983 and Barr and Huhndorf (2001). The Asterinales according to Barr and Huhndorf (2001) include biotrophs that grow superficially on or are erumpent from the substrate and tend to be tropical or subtropical in distribution.…”

“…The Asterinales according to Barr and Huhndorf (2001) include biotrophs that grow superficially on or are erumpent from the substrate and tend to be tropical or subtropical in distribution. Within the ascomata short wide asci develop without a hamathecium, or with apically free paraphyses.…”

“…(Arx and Müller 1975). The fruiting bodies of Asterinaceae are small, shield shaped (dimidiate) or elongated ascomata called thyriothecia and develop underneath the dark surface mycelium (Barr and Huhndorf 2001). Thyriothecia of Asterinaceae are closely attached to the host plant cuticle and have an upper dark wall (scutellum) which is one cell layer thick and composed of isodiametrical or cylindrical cells.…”

Phylogenetic relationships and new records of Asterinaceae (Dothideomycetes) from Panama

2010

Asterinaceae are small obligately biotrophic pathogens growing superficially on living leaves of higher plants in tropical and subtropical regions worldwide. The species-rich but rarely studied ascomycete group has an uncertain placement within the Dothideomycetes because molecular data are missing completely up to now. Based on nuclear DNA from fresh material of five Asterina spp. and a related anamorphic stage from Panama, we present the first molecular phylogenetic hypothesis of the Asterinaceae within the Dothideomycetes. A combined SSU and LSU rDNA phylogenetic analysis shows that species of Asterina and its anamorphs form a well supported monophyletic clade within the Dothideomycetes with Venturiaceae as sistergroup. Three Asterina spp. included in the molecular study are new records for Panama and Central America with new records of host plant species: A. cestricola on Cestrum rugulosum (Solanaceae), A. weinmanniae on Weinmannia pinnata (Cunoniaceae) and A. zanthoxyli on Zanthoxylum scheryi (Rutaceae). A. cestricola and A. weinmanniae are illustrated here for the first time.

“…Most members of the Dothideomycetes are pathogens, endophytes or epiphytes on living plants and lichens, and saprobes on dead or partially decaying plants in leaf litter or herbivore dung , Hyde et al 2013. The primary characters that define Dothideomycetes are ascolocular ascoma and bitunicate, usually fissitunicate asci (Nannfeldt 1932, Luttrell 1955, Eriksson 1981, Barr & Huhndorf 2001, Schoch et al 2009a. However these characters especially the bitunicate or fissitunicate asci are also shared in other classes, such as Chaetothyriaceae in Eurotiomycetes .…”

Towards a natural classification of Dothideomycetes 5: The genera Ascostratum, Chaetoscutula, Ceratocarpia, Cystocoleus, and Colensoniella (Dothideomycetes incertae sedis)

et al. 2014

In the Outline of Ascomycota 2009, 116 genera were listed under Dothideomycetes, genera incertae cedis. In the present study, we re-examined the generic types of Ascostratum, Chaetoscutula, Ceratocarpia, Cystocoleus and Colensoniella which are relatively poorly documented. We re-described and illustrated the type species of these genera and suggest higher level placements based on a modern classification system. Ascostratum is placed in Myriangiaceae because of similarities with Anhelia, both genera have ascostromata with numerous locules in the upper part and 4-7 transversely septate ascospores. Chaetoscutula is similar to Pododimeria in having the same host and septate, olivaceous-brown ascospores and thus is transferred to Pseudoperisporiaceae. Colensoniella has apothecioid ascomata but 1-septate oblong, uniseriately ascospores that many break in the centre form part-spores and is referred to Patellariaceae. Cystocoleus is a typical of any family of Dothideomycetes, but phylogenetic analysis showed this genus to cluster in Capnodiales incertae sedis. Ceratocarpia has glabrous ascomata, muriform ascospores and evanescent pseudoparaphyses so placed in Chaetothyriaceae. By illustrating the genera we hope to stimulate fresh collections so that these genera can be epitypified and molecular data analyzed to establish a truly natural classification.
