Abstract

Novel species of microfungi described in the present study include the following from Australia: Catenulostroma corymbiae from Corymbia, Devriesia stirlingiae from Stirlingia, Penidiella carpentariae from Carpentaria, Phaeococcomyces eucalypti from Eucalyptus, Phialophora livistonae from Livistona, Phyllosticta aristolochiicola from Aristolochia, Clitopilus austroprunulus on sclerophyll forest litter of Eucalyptus regnans and Toxicocladosporium posoqueriae from Posoqueria. Several species are also described from South Africa, namely: Ceramothyrium podocarpi from Podocarpus, Cercospora chrysanthemoides from Chrysanthemoides, Devriesia shakazului from Aloe, Penidiella drakensbergensis from Protea, Strelitziana cliviae from Clivia and Zasmidium syzygii from Syzygium. Other species include Bipolaris microstegii from Microstegium and Synchaetomella acerina from Acer (USA), Brunneiapiospora austropalmicola from Rhopalostylis (New Zealand), Calonectria pentaseptata from Eucalyptus and Macadamia (Vietnam), Ceramothyrium melastoma from Melastoma (Indonesia), Collembolispora aristata from stream foam (Czech Republic), Devriesia imbrexigena from glazed decorative tiles (Portugal), Microcyclospora rhoicola from Rhus (Canada), Seiridium phylicae from Phylica (Tristan de Cunha, Inaccessible Island), Passalora lobeliae-fistulosis from Lobelia (Brazil) and Zymoseptoria verkleyi from Poa (The Netherlands). Valsalnicola represents a new ascomycete genus from Alnus (Austria) and Parapenidiella a new hyphomycete genus from Eucalyptus (Australia). Morphological and culture characteristics along with ITS DNA barcodes are also provided.

Fungi associated with black mould on baobab trees in southern Africa

“…The genus includes three species with the other two being O. elatum (isolated from wood) and O. frigidarii (isolated from a cooled room) (Crous et al 2007). The previous isolation of O. adansoniae by Crous et al (2013) was only obtained from a single tree from the same region as the present study. Interestingly, this species was not isolated in the present study and this suggests that the fungi associated with the black mould syndrome represent a complex of fungi that are apparently not consistently present.…”

“…in New Zealand (Crous et al 2007) and needles of Pinus monophylla in the Netherlands (Crous et al 2011). More recently, R. eucalypti, the first species in the genus associated with sexual structures, was isolated from leaf spots on Eucalyptus globulus in Ethiopia (Crous et al 2014).…”

“…in New Zealand (Crous et al 2007) and needles of Pinus monophylla in the Netherlands (Crous et al 2011). More recently, R. eucalypti, the first species in the genus associated with sexual structures, was isolated from leaf spots on Eucalyptus globulus in Ethiopia (Crous et al 2014). It is not clear whether any of these species are pathogenic to their hosts, but the genus is closely related to the Cladosporiaceae and the Capnodiaceae, both families that include known plant pathogens and sooty mould fungi ).…”

“…It has been hypothesised that rock inhabiting fungi might have given rise to various plant and insect pathogens, as the inhospitable habitat may pre-dispose these fungi to easily adapt to new hosts and environments (Gueidan et al 2008;. Crous et al (2013) described a novel species of Ochrocladosporium (Pleosporales), O. adansoniae, from black mould symptoms on African baobabs in South Africa. The genus includes three species with the other two being O. elatum (isolated from wood) and O. frigidarii (isolated from a cooled room) (Crous et al 2007).…”

Characterization of Phytophthora hybrids from ITS clade 6 associated with riparian ecosystems in South Africa and Australia

“…These included P. amnicola 199 (Crous et al 2012), P. thermophila (Jung et al 2011) and P. taxon PgChlamydo (Brasier et al 200 2003a). All three of these species occur in Australia, but only P. taxon PgChlamydo occurs in…”
