“…The erumpent perithecia of the former occur aggregated in a prosenchymatous stroma, whereas the latter, currently including two genera (Mazzantia Montagne and the highly speciose Diaporthe Nitschke), produce aggregated, stromatic ascocarps (Castlebury et al 2002;Rossman et al 2007b). The Sydowiellaceae, as recently circumscribed based on gene sequences (Kruys and Castlebury 2012), form an assemblage of morphologically diverse genera that seem to lack shared defining morphological characters. Family Gnomoniaceae is the diaporthalean family that combines the set of characters most comparable to Spataporthe.…”

A perithecial ascomycete, Spataporthe taylori gen. et sp. nov., represented by >70 sporocarps is preserved by cellular permineralization in marine carbonate concretions dated at the Valanginian-Hauterivian boundary (Early Cretaceous) from Vancouver Island, British Columbia, Canada. The spheroid perithecia with lumina 330-470 mm wide and 220-320 mm high are densely distributed and entirely immersed in the tissues of a coniferous leaf. The perithecial wall consists of an outer layer of large pseudoparenchyma and an inner layer of thin filamentous nature. Perithecial necks are incompletely preserved due to taphonomic abrasion; they have a bell-shaped chamber at the base and a narrow channel, with longitudinally aligned hyphae above. The basal chamber of the neck is filled with a plug of pseudoparenchyma, which subsequently disintegrates to form a peripheral collar; periphyses are present on the basal chamber walls. A pseudoparenchymatous hymenium lines the bottom of perithecia. Asci are clavate, with thinly tapered bases, and small (30-47 mm long and 12-20 mm wide at tip), ornamented with minute papillae. They become detached from the hymenium to float freely in the perithecium. No unequivocal ascospores were found, although smaller units are present in some of the asci. The combination of immersed perithecia with complex wall structure and a well-defined hymenium, absence of paraphyses, and persistent, detachable inoperculate asci is consistent with order Diaporthales of class Sordariomycetes. The small clavate asci are comparable to those found in family Gnomoniaceae. Perithecioid ascomata are rare in the fossil record, and bona fide perithecia are known with certainty only from the Early Devonian Rhynie Chert and Cenozoic amber. Spataporthe taylori contributes a well-characterized Early Cretaceous occurrence, which is also the oldest to date, to the scarce fossil record of the Sordariomycetes and a second taxon to the fungal flora of the locality, which also includes a basidiomycete. As the oldest representative of the Diaporthales, Spataporthe provides a minimum age (136 Ma) for the order and a direct calibration point for studies of divergence times in the ascomycetes.

“…1). Characteristics of the new family agree with Diaporthales, i.e., perithecia immersed with long necks and a diaporthalean-type centrum development, lack of true paraphyses, and septate ascospores (Barr 1978, Samuels & Blackwell 2001, Castlebury et al 2002, Kruys & Castlebury 2012. Melansporellaceae is distinct from other families in Diaporthales in having oblong or fusoid 8-spored, irregularly uniseriate asci and ovoid, brown conidia, with a distinct hyaline sheath and surface structures.…”

Melansporellaceae fam. nov. is introduced to accommodate a genus of diaporthalean fungi that is a phytopathogen causing walnut canker disease in China. The family is typified by Melansporella gen. nov. It can be distinguished from other diaporthalean families based on its irregularly uniseriate ascospores, and ovoid, brown conidia with a hyaline sheath and surface structures. Phylogenetic analysis shows that Melansporella juglandium sp. nov. forms a monophyletic group within Diaporthales (MP/ML/BI=100/96/1) and is a new diaporthalean clade, based on molecular data of ITS and LSU gene regions. Thus, a new family is proposed to accommodate this taxon.

Fungi associated with woody tissues of Acer pseudoplatanus in forest stands with different health status concerning sooty bark disease (Cryptostroma corticale)

From 2018 to 2020, Germany experienced periods of exceptional weather conditions. Extremely high summer temperatures and precipitation deficits induced stress and mortality in forest trees. Acer pseudoplatanus (sycamore) was one of the affected tree species. Symptoms of sooty bark disease (SBD) and severe damage of entire stands, both caused by the fungal species Cryptostroma corticale, were reported more frequently. To explore the non-symptomatic distribution of C. corticale, wood cores from visibly healthy sycamore stems were sampled and all outgrowing fungi were identified and recorded. In total, 50 trees, aged 30–65 years, were sampled at five different forest stands, from which 91 endophytic filamentous morphotypes could be isolated. The fungal endophytic community in the woody tissue of the sycamore trees varied greatly at the different sites and between the trees. The number of isolated morphotypes at the different sites ranged from 13 to 44 and no morphotype was found at all sites. At 1.20-m stem height, 3.3 fungi could be isolated from woody tissue per tree on average. The most abundant species isolated from visibly healthy sycamore in regard to both occurrence at the studied sites and continuity was C. corticale. It was recorded at four of the studied forest stands, from 26% of all studied sycamore trees, and had a frequency of 7.85% relative to the 293 isolated filamentous strains that were isolated. The second most abundant species was Xylaria longipes followed by Lopadostoma turgidum. In this study clear evidence for the endophytic lifestyle of C. corticale is presented which thus appears to be spread further than expected based on visible SBD symptoms.
