Abstract A description is provided for Didymella applanata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Rubus idaeus (raspberry), R. fruticosus (blackberry) and R. ursinus var. loganobaccus (loganberry). Also on R. australis. DISEASE: Spur blight (in USA) and sometimes referred to as cane blight (in Europe). Early symptoms are purplish blotches mainly on the epidermis at the nodes round the base of leaves and sometimes between the nodes on the lower portions of the stems. As the disease progresses the blotches increase in size extending upward and downward along the cane and sometimes the lesions coalesce to form a discoloured cane. Didymella applanata has been reported to cause dieback (2, 457; 32, 572; 41, 353) and witches' brooms (2, 457). GEOGRAPHICAL DISTRIBUTION: Africa, Asia, Australasia & Oceania, Europe and North America (CMI Map 72, ed. 3, 1977). New records not mapped are: Europe (Czechoslovakia). TRANSMISSION: By ascospores and conidia released during wet or extremely moist conditions (10, 530; 55, 1875; Wormald, 1939; Converse, 1966). In the UK small numbers of ascospores have been trapped in raspberry plantations throughout the summer and early autumn when RH exceeded 70% and temperatures above 12°C prevailed for at least 12 h (37, 201). It invades both unwounded and wounded tissues (9, 117-118; 10, 531). Entry into canes is also achieved through wounds created by Diplosis (gall fly) in Germany (11, 381) and by Thomasiniana theebaldi (midge) (28, 340; 32, 86; 34, 728; 39, 120; 43, 519). As a rule the fungus invades all regions of the cortex except the cork which acts as a barrier (9, 117-118; 10, 531; 11, 381) but it has been known to cause deeper lesions on midge larval feeding areas and frequently penetrates the stem to the pith and kills the cane (32, 86).

Abstract A description is provided for Septoria cannabis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Cannabis sativa (hemp). DISEASE: White leaf spot or leaf blight of hemp. Symptoms usually appear on basal leaves as round or ellipsoidal to polygonal, whitish or ochraceous yellow lesions with a conspicuous dark brown border. Affected leaves become curled and withered up towards the edges and fall prematurely leaving much of the lower part of the stem defoliated (15, 97, 805). GEOGRAPHICAL DISTRIBUTION: Asia, Europe and North America (CMI Map No. 477, ed. 1, 1971). New records not mapped are: Asia (Kashmir, Pakistan). TRANSMISSION: Detailed studies have not been reported but conidia are presumed to be disseminated by rain-splash and wind blown water. The fungus could also be carried over in crop residues.

Abstract A description is provided for Phragmidium rubi-idaei. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Rubus idaeus (raspberry) and a few wild Rubus species. DISEASE: Cane rust or western yellow rust of raspberry, infecting canes, leaves, petioles and fruiting laterals. GEOGRAPHICAL DISTRIBUTION: Widespread throughout temperate areas in North America, Europe, U.S.S.R. and Japan. Also in Australia and New Zealand. TRANSMISSION: By wind-blown spores. Basidiospores arise from teliospores on dead leaves on the ground in early spring and infect through both leaf surfaces; aeciospores and urediospores apparently infect only through the lower surface (Zeller & Lund, 1934).

Abstract A description is provided for Hypoderma rubi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: This species has been reported on leaves, petioles and twigs of a wide range of woody plants, mostly dicotyledons, but even including one species of conifer. The principal host, however, and the one on which it is most commonly collected, is Rubus. DISEASE: Hypoderma rubi usually fruits only after the apparently normal senescence and death of the host plant, but on Rubus idaeus and related species ascocarp initials are occasionally found developing on current year's living floricanes in pale spots surrounding the point of peduncle attachment. The fruit on affected panicles is frequently then aborted, and it has been surmised that in these cases the fungus enters the biennial cane at the end of the first season through the petioles of senescent deciduous leaves. GEOGRAPHICAL DISTRIBUTION: Widespread in Europe and North America, apparently also occurring in temperate South America and Asia. TRANSMISSION: By air-borne ascospores in wet or humid weather.

Abstract A description is provided for Septoria carthami. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Carthamus tinctorius and C. mareoticus. DISEASE: White leaf spot of safflower. Early symptoms appear as small distinct brownish lesions which enlarge and become circular or irregular and up to 6 mm wide. As the disease progresses lesions sometimes coalesce to form large blotches. Older lesions are usually bordered by dark brick margins with ash grey centres. GEOGRAPHICAL DISTRIBUTION: Africa (Egypt); Asia (Iraq, Turkey, USSR, West Siberia); Europe (Bulgaria, Rumania); North America (USA, Indiana, Texas). TRANSMISSION: It has been claimed that the fungus was introduced into West Siberia with infected seeds (14, 493-494). Also the fungus is probably disseminated by water-splash or by mechanical means.

Español.  Se dan a conocer nuevas localizaciones y datos corológicos para 98 especies (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) de algas bentónicas marinas recolectadas en el intermareal y submareal de más de 80 localidades de las costas atlánticas y cantábricas de la Península Ibérica. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii son novedad para Portugal y 5 especies (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia y Derbesia marina stadium Halicystis ovalis) son nuevas citas para Galicia. Paralelamente, se aportan 101 primeras citas provinciales (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) y, además, se dan a conocer 108 segundas citas provinciales. Aunque la flora bentónica marina del Atlántico Peninsular ha sido objeto de numerosos estudios, estos nuevos hallazgos corológicos ponen en evidencia que todavía son necesarios más estudios florísticos en estas costas.English.  In this work, we provide new records and geographical distribution data for 98 seaweeds (61 Rhodophyta, 22 Ochrophyta, 15 Chlorophyta) inhabiting more than 80 sites (intertidal and subtidal) of the Atlantic Iberian Peninsula. Polysiphonia devoniensis, P. fibrata y Zonaria tournefortii are new records for Portugal and 5 species (Bonnemaisonia hamifera, Calosiphonia vermicularis, P. devoniensis, Hincksia intermedia and Derbesia marina stadium Halicystis ovalis) are new records for Galicia. Moreover, 101 new records are reported for the first time in the studied provinces (2 Guipúzcoa, 1 Vizcaya, 8 Cantabria, 5 Asturias, 7 Lugo, 1 A Coruña, 8 Pontevedra, 1 Beira litoral, 15 Estremadura, 20 Alentejo, 25 Algarve y 8 Cádiz) and 108 for the second time. Although the Atlantic marine algae of the Iberian Peninsula are well studied, these new findings show that further floristic studies are necessary to complete our knowledge of the natural heritage of this region.

I wish to draw particular attention to this genus and its allies. I have, in 1865, drawn a parallel between the group and the Hawk Moths, from the young stages and the peculiar pupation, and in my pamphlet on “the Hawk Moths of North America,” I hae discussed the probabilities of their relationship. But I here wish to point out that the group is American; that in America we may except to find old types among that portion of the fauna which is indigenous, pre-tertiary, and to this Citrheronia belongs.
