In April 2012, outbreaks of a destructive root disease were observed in strawberry cv. Chandler in Buncombe, New Hanover, and Roman counties, North Carolina. Samples from Rowan (ID 13175) and Buncombe (ID 13193) counties submitted to the Plant Disease and Insect Clinic of the Department of Plant Pathology, North Carolina State University, exhibited yellowing and wilting of leaves and extensive root necrosis, and disease severity based on field symptoms ranged from 20 to 30%. To identify the pathogen, five small pieces of necrotic crown and root tissues were taken from each sample, surface disinfested for 1 min in a 1.5% sodium hypochlorite solution, and plated onto potato dextrose agar (PDA) with 0.5 g liter–1 of streptomycin sulfate. Colonies developing from the tissue samples were transferred to PDA. Colonies from both samples were identical, grew relatively slowly, and gradually turned yellowish to partially brownish. After about 7 days, abundant conidia were formed. These were hyaline, mostly straight with both ends rounded, predominantly three septate, and 40 to 50 × 5 to 10 μm. Based on morphological characteristics, these isolates were identified as a species of Cylindrocarpon (1) To confirm the original identification of the fungus as a species of Cylindrocarpon, genomic DNA of both isolates was extracted from mycelia using DNeasy Plant Mini Kit (Qiagen Inc., Valencia, CA) and analyzed using PCR (2). The internal transcribed spacers (ITS)1 and (ITS)2 flanking the 5.8S rRNA regions were amplified and sequenced using universal primers ITS1 (forward) and ITS4 (reverse). The sequences of the 421 bp (GenBank KC847090 and KC847091) of both isolates were identical. Furthermore, a BLASTn search of these sequences showed homology of 99% with the sequences of Cylidrocarpon species (AB369421.1, AM419069.1, AM419074.1, AY295332.1, JN031017.1, JN253505.1, and JQ886422.1), To fulfill Koch's postulates, inoculum of each isolate was prepared and adjusted to 1.5 × 107 conidia/ml using a hemacytometer. ‘Chandler’ strawberry plants were grown in 25-cm diameter plastic pots (one seedling per pot) in the greenhouse and five 6-week-old plants were injected with conidia of each isolate into the base of crown using a 5-ml syringe. The plants were covered with clear plastic for 24 h and left on the greenhouse bench with a 16-h photoperiod and 25/20°C day/night temperatures and assessed for disease development 14 days after inoculation. The inoculated plants exhibited wilting and root necrosis, consistent with the symptoms observed on strawberry plants in the field. Control plants treated with distilled water remained healthy. Isolations were made from the inoculated plants and the fungus used for inoculation was recovered from all plants. The morphology of these isolates was in agreement with published descriptions of Cylindrocarpon (1). To our knowledge, this is the first report of a Cylindrocarpon sp. causing crown and root rot on strawberry in North Carolina and effective disease management strategies need to be explored. }, number={9}, journal={PLANT DISEASE}, publisher={Scientific Societies}, author={Adhikari, T.

Until recently, there have been no living cultures of C. havanensis and it has thus not been possible to assess its taxonomic status. Isolates thought to represent this fungus have, however, emerged from surveys of Eucalyptus in Mexico and Hawaii (U.S.A.). Results of this study showed that these isolates represent C. havanensis but reside in a genus distinct from Cryphonectria sensu stricto, which is described here as Microthia. Isolates of an unidentified fungus occurring on Myrica faya in the Azores and Madeira also grouped in Microthia and were identical to other M. havanensis isolates. Cryphonectria coccolobae, a fungus occurring on sea grape (Coccoloba uvifera) in Bermuda and Florida, was found to be morphologically identical to Microthia and is transferred to this genus, but as a distinct species. Surveys for M. coccolobae on sea grape in Florida, yielded a second diaporthalean fungus from this host. This fungus is morphologically and phylogenetically distinct from M. coccolobae and other closely related taxa and is described as Ursicollum fallax gen. et sp. nov. Phylogenetic analyses in this study have also shown that isolates of C. eucalypti, a pathogen of Eucalyptus in South Africa and Australia, group in a clade separate from all other groups including that representing Cryphonectria sensu stricto. This difference is supported by the fact that Cryphonectria eucalypti has ascospore septation different to that of all other Cryphonectria species.

A fungus sporulating profusely on symptomatic needles was identified as Stigmina lautii. Since then, three additional specimens have been received—on blue spruce from Ashe County, on Norway spruce (P. abies) from Avery County, and on Picea sp. from Cherokee County. These counties are all in western North Carolina but are not contiguous, indicating that the fungus is probably widespread in the western part of the state. S. lautii was described by Sutton (2) in 1973 on black spruce (P. mariana) and white spruce (P. glauca) collected from various locations in Manitoba and Saskatchewan, Canada. The only other reference found to the fungus is a specimen collected in British Columbia, Canada, on P. glauca in 1972 (2). The morphology of the North Carolina specimens of S. lautii is essentially as described by Sutton. The dark brown, superficial, flattened sporodochia are developed only through stomata. Sporodochia are found both on symptomatic needles as well as on adjacent green needles. Conidiophores arise only laterally from the lower, outer cells of the sporodochium, and are macronematous, mononematous, brown, smooth, unbranched, 1 to 2 septate, and 10 to 20 × 4 to 6 μm. Conidiogenous cells are brown, monoblastic, integrated, terminal, percurrent with 3 to 4 annelations, and 6 to 12 × 4 to 5 μm. Conidia are pale brown, cylindrical to fusiform, often curved, thick walled, verrucose, 5 to 8 distoseptate, and 25 to 45 × 5 to 6 μm. Superficially, the sporodochia of S. lautii might be confused with pycnidia of Rhizosphaera kalkhoffii, which also arise through stomata. The latter fungus also is associated with a needle blight of Picea spp. in western North Carolina. Both fungi were present on one specimen examined. Currently, no information is available on the pathogenicity of S. lautii, but its association with typical needle blight symptoms and the known pathogenicity of other Stigmina spp. on conifers make it likely that the fungus is pathogenic to spruce. To my knowledge, this is the first report of S. lautii in the United States, and P. pungens and P. abies represent new host records for the fungus.

Abundant stromata of Gyrostroma austroamericana, the anamorph of Thyronectria austroamericana, were associated with the cankers. A visit to the Zoological Park during August 1999 revealed seven additional honey locust trees with multiple branch and stem cankers and dieback. All infected trees had perithecia of T. austroamericana and/or its anamorph. The fungus is distinguished by the large clusters of yellow-brown perithecia with dark brown tips produced on stromata emerging from lenticels, elliptical muriform ascospores, and sparse ascoconidia (1,2). Ascoconidia form as the result of ascospores budding within the ascus. Other trees of the cultivar are an integral part of the landscaping theme of the African Pavilion of the park, and park staff were concerned about disease spread. Infected trees were 8 years old, and several had evidence of sunscald cankers, a common infection court of T. austroamericana (2). Thornless cultivars of honey locust are popular landscape plants in the central and eastern United States and may be seriously affected by T. austroamericana (2). Apparently ‘Shade Master’ is very susceptible to the fungus and should not be used as a landscape tree, especially where the disease has been reported.

In tests to determine the suitability of this rust as a biological control agent for R. penetrans in Hawaii, a species now thought to be conspecific with R. argutus, rooted cuttings of the Hawaiian plants were grown at North Carolina State University, inoculated, and observed. Other introduced weedy Rubus spp. in Hawaii, including R. ellipticus, R. rosifolius, and R. glaucus, as well as the two endemic species R. hawaiensis and R. macraei, also were inoculated. No species of Rubus are of commercial importance in Hawaii, but the protection of the native species, of which R. macraei is rare, was of utmost concern. The native Hawaiian species did not survive well in North Carolina in this study, however. Later availability of a plant pathogen containment laboratory in Hawaii enabled similar tests to be conducted at that facility. In addition to the above species, R. spectabilis (salmonberry), a species native to the Pacific Northwest with which the Hawaiian Rubus spp. are thought to share a common ancestor, was inoculated in Hawaii. Infection with G. nitens under natural field conditions becomes apparent only when sporulation occurs on floricanes the second year following infection. However, experimental inoculation led to early responses of chlorotic leaf flecking and puckering, leaf and stem contortion, and stem gall formation, indicating the sensitivity of R. penetrans (= R. argutus ), R. hawaiensis, and R. macraei to this rust. Apparent systemic infection also resulted in sporulation on one plant of R. macraei. Ability to attack the endemic species suggests that G. nitens would not be suitable for release in Hawaii as a biological control agent, at least on the islands with populations of the native species.}, number={3}, journal={BIOLOGICAL CONTROL}, author={Gardner, DE and Hodges, CS and Killgore, E and Anderson, RC}, year={1997}, month={Nov}, pages={151–158} } @article{johnson_sutton_hodges_1997, title={Etiology of apple sooty blotch disease in North Carolina}, volume={87}, ISSN={["0031-949X"]}, DOI={10.1094/PHYTO.1997.87.1.88}, abstractNote={ Sooty blotch disease of apples (Malus × domestica), previously attributed to the fungus Gloeodes pomigena, was shown to be a disease complex caused by fungi previously considered mycelial types of G. pomigena.
