' Foreword ; .\ _ This summary of the diseases of fbreSt and shr.de trees, ornam-ental and miscellaneous plants in the United States in 1*323 follows the same general plan as those of the preceding years. The sources upon which the information is based are as follows: (l) 'collaborators, (2) specialists in the Office -of Forest Pathology, (3) "^^"ticles in botanical journals, and (4) special reporters. Many reports of new occurrences were ree-^ived for I923 both for states and for the United States. In the accompanying summary these first occurrences have been noted" by sym^bols 'before each individual report. Nev/ York, Mississippi, Minnesota, Florida and Connecticut contributed the largest number of first reports. Many occurrences are given which have been obtained from literature, f r-am --the- he-rbarium-'-of Pathological Collec- tions, or from past records of the Plant Disease Survey. Quito a number of diseases -have been omitted due to. their unimportance or to the fact that they have been reported in other years. 'It is not the object of this summary to enumerate all -of tlie diseases that have been reported during the year,' but to give facts concerning only s om^e of the m.ore important ones. Owing to the nature of the data it is presented herewith in list; ' form • •7-;-^- V/here specimens are not indicated the report is based on the authority of the person cited. The' date given is that of its earliest re- ported appearance in I923. Reports from British Columbia are given on ac- count of the probable occurrence of .the' disease being also in Washington and Idaho. The following symbols are used:* indicates a specVm-n in Pathologi- cal Collections; + preceding disease .indicates 'the first report of the disease to the Plant Disease Survey; + preceding state, indicates the first report from the state to the Plant Disease Survey. References have been given and in some instances brief abstracts made of recent articles which may be of service to those who do not have access to all the botanical journals. A list of collaborators is given on the opposite page. The nam.es of the special reporters are as follows: 350 Boyce, J. S. Harter_, Li L. Posey, G. B. Dewey, L. H. Haskell, R. J. Rhodes, A. L.

    Cytospora Canker

    report on RPD No. 604 PLANT April 1996 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN CYTOSPORA OR LEUCOSTOMA CANKER OF SPRUCE Cytospora or Leucostoma canker, the most common and damaging disease of spruce, is caused by the fungus Leucocytospora kunzei, synonym Cytospora kunzei (teleomorph or sexual state Leucostoma kunzei, synonym Valsa kunzei). This canker occurs on several conifers from New England to the western United States. Colo- rado or Colorado blue (Picea pungens) and Norway spruce (Picea abies), used for ornament and in wind- breaks, are the species most commonly affected in Illinois. The disease has reached epidemic proportions on Engelmann spruce (Picea engelmannii) and Douglas- fir (Pseudotsuga menziesii) in the eastern Rocky Mountains due to a succession of dry years in the area. Other trees reported as susceptible to the disease are given in Table 1. Spruce trees less than 10 to 15 years old usually do not have Cytospora canker. In landscape nurseries, how- ever, small branches of young Colorado blue and oc- casionally white spruces may be killed. Three varieties of Leucostoma kunzei are recognized by some spec- ialists: var. piceae on spruces, var. superficialis on pines, and var. kunzei on other conifers. Figure 1. Colorado spruce affected by Cytospora Dead and dying branches call attention to Cytospora or canker. Leucostoma canker with older branches more suscep- tible than young ones. The fungus kills areas of bark, usually at the bases of small twigs and branches, creating elliptical to diamond-shaped lesions. If the lesions enlarge faster than the stem and girdle it, the portion beyond the canker also dies.

    Journal of the Lundy Field Society, 2, 2010 LUNDY FUNGI: FURTHER SURVEYS 2004-2008 by JOHN N. HEDGER1, J. DAVID GEORGE2, GARETH W. GRIFFITH3, DILUKA PEIRIS1 1School of Life Sciences, University of Westminster, 115 New Cavendish Street, London, W1M 8JS 2Natural History Museum, Cromwell Road, London, SW7 5BD 3Institute of Biological Environmental and Rural Sciences, University of Aberystwyth, SY23 3DD Corresponding author, e-mail: [email protected] ABSTRACT The results of four five-day field surveys of fungi carried out yearly on Lundy from 2004-08 are reported and the results compared with the previous survey by ourselves in 2003 and to records made prior to 2003 by members of the LFS. 240 taxa were identified of which 159 appear to be new records for the island. Seasonal distribution, habitat and resource preferences are discussed. Keywords: Fungi, ecology, biodiversity, conservation, grassland INTRODUCTION Hedger & George (2004) published a list of 108 taxa of fungi found on Lundy during a five-day survey carried out in October 2003. They also included in this paper the records of 95 species of fungi made from 1970 onwards, mostly abstracted from the Annual Reports of the Lundy Field Society, and found that their own survey had added 70 additional records, giving a total of 156 taxa. They concluded that further surveys would undoubtedly add to the database, especially since the autumn of 2003 had been exceptionally dry, and as a consequence the fruiting of the larger fleshy fungi on Lundy, especially the grassland species, had been very poor, resulting in under-recording. Further five-day surveys were therefore carried out each year from 2004-08, three in the autumn, 8-12 November 2004, 4-9 November 2007, 3-11 November 2008, one in winter, 23-27 January 2006 and one in spring, 9-16 April 2005.

However, a new and widely distributed Cytospora species on quaking aspen was recently described (Cytospora notastroma Kepley & F.B. Reeves). Here, we show the relative pathogenicity, abundance, and frequency of both species on quaking aspen in portions of the Rocky Mountain region, and constructed species-level phylogenies to examine possible hybridization among species. We inoculated small-diameter aspen trees with one or two isolates each of C. chrysosperma and C. notastroma in a greenhouse and in environmental growth chambers. Results indicate that both Cytospora species are pathogenic to drought-stressed aspen, and that C. chrysosperma is more aggressive (i.e., caused larger cankers) than C. notastroma, particularly at cool temperatures. Neither species cause significant canker growth on trees that were not drought-stressed. Both C. chrysosperma and C. notastroma are common on quaking aspen, in addition to a third, previously described species, Cytospora nivea.

The disease symptoms, the morphology of fruiting bodies and fungal culture, and DNA barcoding were combined for determining the fungi at the genus or species level. DNA barcoding is a standardized and automated identification of species based on recognition of highly variable DNA sequences. DNA barcoding has a wide application in the diagnostic purpose of fungi in biological specimens.

    report on RPD No. 627 PLANT February 1982 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN HOLLYHOCK RUST Rust caused by the fungus Puccinia malvacearum is the most common and widespread disease of hollyhock (Althaea rosea). Hollyhock rust was first reported in 1852 in Chile, where it is indigenous. In 1857 it was observed in Australia, and in 1869 in Spain, from where it spread rapidly over the rest of Europe. By 1875, rust was reported in South Africa, and it reached the United States in 1886. Today, the disease occurs worldwide. Severely rusted leaves turn yellow, wither, and drop prematurely. Ragged and unsightly plants result, but Figure 1. Hollyhock rust pustules (sori) on the upper hollyhocks infected with rust are rarely killed. It is not and lower sides of hollyhock leaf. uncommon to find the disease severe in the spring and autumn but declining in midsummer, especially during drought periods. The same rust fungus attacks about fifty species in ten genera of the mallow family (Malvaceae) including species of Althaea, Brotex, Kitaibelia, Lavatera, Malope, Malva, Malvastrum, and Sidalcea. Rust is prevalent on common or roundleaf mallow (Malva rotundifolia), a common weed closely related to hollyhock. SYMPTOMS Rust first appears primarily on the undersides of the lower leaves as lemon yellow to orange, almost waxy pustules (or sori) that turn reddish brown to chocolate brown with age. Larger, bright yellow to orange spots with reddish centers develop on the leaf surface opposite the pustules. The rust quickly spreads to other leaves, which become covered with small, reddish brown to chocolate brown pustules.

It is a parallel publication to the Archaeological and Historical Sites Atlas we first published in 2006, and the more recent Gazeteer which both augments the Atlas and catalogues each site in greater detail. Both sets of data are also being mapped onto GIS. We would like to thank everyone who has helped with and supported this project - in particular Neville Geddes, Planning and Environment manager, North England Forestry Commission, for his invaluable advice and generous guidance with the GIS mapping, as well as for giving us information about the archaeological sites in the forested areas for our Atlas revisions; Northumberland National Park and Tarset 2050 CIC for their all-important funding support, and of course Bill Burlton, who after years of sharing his expertise on our wildflower and tree projects and validating our work, agreed to take this commission and pull everything together, obtaining the use of ERIC’s data from which to select the records relevant to Tarset and Greystead. Even as we write we are aware that new records are being collected and sites confirmed, and that it is in the nature of these publications that they are out of date by the time you read them. But there is also value in taking snapshots of what is known at a particular point in time, without which we have no way of measuring change or recognising the hugely rich biodiversity of where we are fortunate enough to live.
