“…While A. flavus had higher incidence(95%), A. niger recorded a percentage incidence of 5%. Earlier studies had shown the susceptible nature of P. communis to fungi (Wennekeret al, 2017;Magyar et al, 2011). Moreso, the fungal isolates from this study agrees with Muscat et al, (2017) as they also implicated Aspergillus species to cause spoilage of P. communis fruit.…”

Studies on the nutrient quality and associated spoilage fungi of English pear (Pyruscommunis) were carried out in the Department of Plant Science and Biotechnology Rivers University, Port Harcourt. Healthy and spoilt samples of P. cummunis were purchased from the fruit garden market in D. Line, Port Harcourt and used for the study. Results of Proximate analysis revealed the presence of moisture, ash, lipid, carbohydrate, fiber and protein. It was also observed that all the parameters assessed were higher for the spoilt samples except for moisture (87.51± 0.001) and carbohydrate (10.02± 0.002) which were higher in healthy fruit samples. The mineral contents indicated higher values for all parameters (calcium, phosphorus, potassium, iron, sodium and magnesium) in the healthy samples. However, vitamins A, C, and thiamine were available in higher quantities in healthy fruit samples with equal values recorded for niacin (0.5 ± 0.003) for both healthy and spoilt samples. Anti-nutrient and phytochemical investigations revealed phytate, oxalate, saponin, tannin, carotenoid, polyphynol, flavonoid and lignin to be available in appreciable amounts. Nevertheless, two spoilage fungi viz: Aspergillusflavus and A. niger were isolated fromfrom spoilt fruit samples and implicated to cause spoilage as they both proved pathogenic when inoculated into healthy samples of P. communis. Higher percentage incidence (95%) was recorded for A. flavus whileA. niger had 5%.

“…Wennekeret al, (2017) also reported Fibulorhizoctoniapsychrophila to be the spoilage agent of the pear fruit causing lenticel spot. Pyrigemmulaaurantiaca was also implicated as aprevalent organism of grapevine trees including P. communis (Magyar et al, 2011).…”

The genus Catenularia (Chaetosphaeriaceae) was reviewed, and its relationships with morphologically similar fungi were evaluated using molecular and morphological data. Eleven species are accepted, four of which have been verified with molecular DNA data. The correct epithet ‘cupulifera’ is proposed for the type species C. cupuliferacomb. nov. Four other combinations are proposed, namely C. catenulatacomb. nov., C. elsikiicomb. nov., C. minorcomb. nov. and C. novae-zelandiaecomb. nov.Catenularia is an uncommon fungus inhabiting mainly decaying bark, wood and bamboo culms of various hosts and shows a widespread geographical distribution. It is circumscribed for fungi with mononematous, macronematous, simple conidiophores with terminal monophialides, usually accompanied with capitate hyphae. The conidia are aseptate, brown, cuneiform to rounded-obconic with an angular outline, adhering in chains. The diagnostic values of taxonomic characteristics of capitate hyphae and conidia (i.e. colour, shape in transverse section, setulae and formation) at the generic level were evaluated. An account of morphology, taxonomy and phylogeny of species accepted in Catenularia is provided. Based on ribosomal DNA sequences, Chalarodes obpyramidatasp. nov., characterised by catenate, angular, hyaline conidia with apical setulae, is revealed as closely related to Catenularia. The new genus Fuscocatenulagen. nov. is proposed for catenularia-like fungi having pigmented conidia with protracted maturation and round outline, with two species accepted, F. submersacomb. nov. and F. variegatacomb. nov. A new species Nawawia antennatasp. nov. is introduced and Nawawia is compared with morphologically similar taxa.

The genera Menisporopsis, Multiguttulispora and Tainosphaeria (Chaetosphaeriaceae) are saprobes inhabiting decaying plant material. This study is based on an integrated morpho-molecular characterisation to assess their generic concepts and explore phylogenetic relationships. Menisporopsis is revealed as polyphyletic, and species with 1-septate conidia and synnemata growing unilaterally along the seta are placed in the new segregate genus Arcuatospora. Codinaea dimorpha and C. triseptata are shown to be congeneric with Multiguttulispora sympodialis, the type species. Two new combinations are proposed: M. sympodialis is found conspecific with M. dimorpha. The Tainosphaeria complex is resolved into three genera. We found that the morphological separation of three groups within the genus is consistent with phylogenetic relationships. Tainosphaeria s. str. is accepted with five species. Tainosphaeria aseptata and T. lunata are transferred to the newly erected Phialoturbella, whereas T. obclavata is revealed as conspecific with Phialogeniculata guadalcanalensis, reducing it to a synonym. A new genus Flectospora is erected for a chloridium-like fungus nested in the Tainosphaeria clade. Based on molecular evidence, we show that asymmetrical, scolecosporous ascospores are a unique teleomorphic characteristic among family members. Therefore, we propose new combinations for Chaetosphaeria hispida in Paragaeumannomyces and Ch. spinosa in the new genus Ericiosphaeria, both exhibiting this rare morphotype.
