“…Pinho et al (2012) analysed nucleotide sequences of ribosomal large subunit (LSU) and ITS region gene data from Anhellia nectandrae Pinho & Pereira (2012) showed it to cluster in Myriangiaceae. This and other genera that lack sequence data need recollection so that molecular studies can confirm and resolve their relationships in Myriangiales.…”

“…Anhellia nectandrae differs from A. escharoides by having paler ascospores and narrower asci, while A. tetracerae and A. tristis are different in having hyaline ascospores (Raciborski 1900, von Arx 1963. Anhellia nectandrae was the first Anhellia species reported parasitizing a member of Lauraceae and differs morphologically and phylogenetically from other previously described species (Pinho et al 2012). Anhellia tabebuiae is a first record of Anhellia on Tabebuia species (Pinho et al 2012).…”

The family Myriangiaceae is relatively poorly known amongst the Dothideomycetes and includes genera which are saprobic, epiphytic and parasitic on the bark, leaves and branches of various plants. The family has not undergone any recent revision, however, molecular data has shown it to be a well-resolved family closely linked to Elsinoaceae in Myriangiales. Both morphological and molecular characters indicate that Elsinoaceae differs from Myriangiaceae. In Elsinoaceae, small numbers of asci form in locules in light coloured pseudostromata, which form typical scab-like blemishes on leaf or fruit surfaces. The coelomycetous, "Sphaceloma"-like asexual state of Elsinoaceae, form more frequently than the sexual state; conidiogenesis is phialidic and conidia are 1-celled and hyaline. In Myriangiaceae, locules with single asci are scattered in a superficial, coriaceous to sub-carbonaceous, black ascostromata and do not form scab-like blemishes. No asexual state is known. In this study, we revisit the family Myriangiaceae, and accept ten genera, providing descriptions and discussion on the generic types of Anhellia, Ascostratum, Butleria, Dictyocyclus, Diplotheca, Eurytheca, Hemimyriangium, Micularia, Myriangium and Zukaliopsis. The genera of Myriangiaceae are compared and contrasted. Myriangium duriaei is the type species of the family, while Diplotheca is similar and may possibly be congeneric. The placement of Anhellia in Myriangiaceae is supported by morphological and molecular data. Because of similarities with Myriangium, Ascostratum (A. insigne), Butleria (B. inaghatahani), Dictyocyclus (D. hydrangea), Eurytheca (E. trinitensis), Hemimyriangium (H. betulae), Micularia (M. merremiae) and Zukaliopsis (Z. amazonica) are placed in Myriangiaceae. Molecular sequence data from fresh collections is required to confirm the relationships and placement of the genera in this family.

“…Ascostratum shows similarities with Anhelia in the family Myriangiaceae as both genera have numerous locules, scattered ascostromata in the upper part, and 4-7 transverse septate ascospores. The position of Anhelia was uncertain in Lumbsch & Huhndorf (2010), however, Danilo et al (2012) accommodated this genus in Myriangiaceae based on phylogenetic analyses. The difference between these two genera is the colour and shape of the ascospores (ellipsoid to fusiform, and hyaline in Ascostratum, versus ovoid to oblong and brown in Anhelia.…”

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

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.
