Species of Sporocadaceae are endophytic (living with a plant), plant pathogenic (causing disease) or saprobic (processing of decayed (dead or waste) organic matter).[4] They are associated with a wide range of host plants.[5][6][7] They are also endophytes or parasitic on humans and animals.[8] Some of them are confirmed to cause human and animal diseases. For example, Pestalotiopsis spp. have been isolated from a bronchial biopsy, corneal abrasions, eyes, feet, fingernails, scalp, and sinuses from the human body.[9][10]
Members of Sporocadaceae are also known as 'pestalotioid fungi',[11] which refers to genera resembling those taxa having affinities with Pestalotia.[12] A former genus, whose species are now split between Pestalotiopsis, Neopestalotiopsis and Pseudopestalotiopsis.[13][14] 'Pestalotia' also encompasses genus Seiridium.[15]
History
The family Sporocadaceae was established by Corda in 1842 with the type genus of Sporocadus.[5][8]
The order of Amphisphaeriales was resurrected by Senanayake et al. (2015), to include Amphisphaeriaceae, Clypeosphaeriaceae and another four novel families derived from Amphisphaeriaceae (Bartaliniaceae, Discosiaceae, Pestalotiopsidaceae and Phlogicylindriaceae).[16] However, the fungal sequence dataset as used in Senanayake et al. (2015),[16] was largely incomplete and some of the introduced families were not well supported statistically. Subsequently, Jaklitsch et al. (2016),[17] synonymised Bartaliniaceae, Discosiaceae, Pestalotiopsidaceae and Robillardaceae, and then revived the older family name of Sporocadaceae to accommodate them (Crous et al. 2015).[18]
Because genera in this family of fungi share the same evolutionary history, it is unlikely that the diversity of secondary metabolites detected in Pestalotiopsis is an exception within the family. Therefore, a large number of potential novel metabolites might be hidden and await discovery. The natural classification system proposed for Sporocadaceae in this study could thus present a major step to screen for novel metabolites in future studies.[5]
Description
Most fungal genera within the Sporocadaceae family have multi-septate (cavity walls) and more or less fusiform (spindle-like shaped) conidia with appendages at one or both ends, frequently with some melanised cells.[12] This genus has undergone many rearrangements since it was first introduced by Italian botanist, lichenologist and mycologist De Notaris (1805–1877), in 1841.[5]
The morphology of the asexual morph genera having acervular (an open, saucer-shaped asexual fruiting body) conidiomata that produce hyaline (resembling glass), pale or dark brown, septate conidia were taken into the consideration by various botanic authors when they were assigned to the family.[8]
Pestalotia-like asexual morphs were classified in Amphisphaeriaceae (Samuels et al. 1987),[19] accommodating 36 genera (Hawksworth et al. 1995).[20]
Many of the Sporocadaceae species were reported as important plant pathogenic fungi that mainly harm various economic crops, such as tea (Camellia sinensis),[21][22] blueberry (Vaccinium corymbosum),[23] and elephant apple, (Dillenia indica).[24] Genera Pestalotiopsis and Neopestalotiopsis cause twig blight and dieback on blueberry plants in Portugal.[25] Genera Neopestalotiopsis, Pestalotiopsis, and Seiridium are found on woody oil plants such as; (Camellia oleifera, Olea europaea (Olive), Paeonia suffruticosa, Sapium sebiferum, and Vernicia fordii) in Sichuan Province, China.[15]
Species of Pestalotiopsis are found on Fagaceae leaves within China.[26] Species Pestalotiopsis kenyana causes leaf spot disease on Zanthoxylum schinifolium (a species of prickly ash) in Sichuan Province, China.[27]
Pestalotioid fungi are also one of the major agents causing leaf spots on mango trees in China.[28]
In addition, members of Sporocadaceae are of particular interest with regard to the production of secondary metabolites, e.g. Pestalotiopsis, Bartalinia and Morinia (Collado et al., 2006,[30] Gangadevi and Muthumary, 2008,[31] Liu et al., 2009).[32]Pestalotiopsis fici was shown to possess a very high number of gene clusters involved in bio-active compound synthesis (Wang et al. 2016).[33]
Studies on Sporocadaceae were mostly based on ITS and LSU sequence data (DNA analysis) and these data sets were not originally informative in resolving generic boundaries within the family (Jaklitsch et al. 2016b).[17] The 2019 study by Liu et al. (2019a), provided a revision of this family complete with morphology and multi-gene phylogeny based on the LSU, ITS and rpb2 sequence data and further analysis using protein coding genes (tef1 or tub2) for each genus.[5]
The family comprised 35 genera in 2022.[12] It was estimated it had 750 species.[8] As accepted in 2020 (with amount of genera);[3]
Pseudopestalotiopsis theae is a plant pathogen affecting tea.
The fungal genus Truncatella in the family Sporocadaceae, and in the Amphisphaeriales order, includes plant pathogens such as Truncatella laurocerasi.
The Pleosporales is the largest order in the fungal class Dothideomycetes. By a 2008 estimate, it contained 23 families, 332 genera and more than 4700 species. The majority of species are saprobes on decaying plant material in fresh water, marine, or terrestrial environments, but several species are also associated with living plants as parasites, epiphytes or endophytes. The best studied species cause plant diseases on important agricultural crops e.g. Cochliobolus heterostrophus, causing southern corn leaf blight on maize, Phaeosphaeria nodorum causing glume blotch on wheat and Leptosphaeria maculans causing a stem canker on cabbage crops (Brassica). Some species of Pleosporales occur on animal dung, and a small number occur as lichens and rock-inhabiting fungi.
Broomella is a genus of fungi in the family Sporocadaceae.
Lepteutypa is a genus of plant pathogens in the family Amphisphaeriaceae. First described by the Austrian mycologist Franz Petrak in 1923, the genus contains 10 species according to a 2008 estimate. It was increased to 15 in 2020.
The Trichosphaeriales are an order of sac fungi. It is monotypic, and consists of the single family, the Trichosphaeriaceae. In 2017, the family of Trichosphaeriaceae was placed in Diaporthomycetidae families incertae sedis, which was accepted by Wijayawardene et al. (2018), and Wijayawardene et al. 2020. The order of Trichosphaeriales was also unplaced. They are generally saprobic and pathogenic on plants, commonly isolated from herbivore dung.
