Gloeotinia granigena
. [Descriptions of Fungi and Bacteria].
Authors: UK, CAB International  , Williams M. A. J. , Spooner B. M. 
Published: July 2021

Abstract

A description is provided for
Gloeotinia granigena
. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Chief host:
Lolium perenne
, but also infects other pasture grasses including
Lolium multiflorum, Lolium temulentum, Bromus
spp.,
Elytrigia
spp.,
Festuca
spp.,
Secale cereale
. DISEASE: Blind seed disease of ryegrass and other grasses. Once the grass flower is infected the endosperm is permeated by the fungal mycelium and the embryo is frequently killed, resulting in failure to germinate. GEOGRAPHICAL DISTRIBUTION: Australasia: Australia (NSW, SA, Tas., Vic.), New Zealand; Europe: Denmark, Eire, England, France, Germany, The Netherlands, Northern Ireland, Norway, Scotland, Sweden, USSR, Wales, North America: Canada (Quebec), USA (OR) (see
CMI Distribution Maps of Plant Diseases
, No. 315). TRANSMISSION: Fungus overwinters in fallen infected seed; apothecia produced in spring coincidentally with flowering of host plant; ascospores forcibly discharged and carried by air currents to open flowers. Macroconidia may also infect additional flowers.

Abstract

A description is provided for
Sclerotinia borealis
. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS:
Lolium perenne
and various cereals, forage grasses and lawn grasses (including
Triticum
cultivars,
Phleum pratense, Agrostis tenuis, Alopecurus pratensis, Anthoxanthum odoratum, Bromus inermis, Dactylis glomerata, Festuca
spp.,
Poa pratensis, Secale cereale
). DISEASE: Snow scald, snow mould. GEOGRAPHICAL DISTRIBUTION: Asia: Japan, USSR; Europe: Finland, Norway, Sweden, USSR; North America: Canada (Alberta, British Columbia, Manitoba, Saskatchewan, Yukon); United States (AK, MN, WA) (see
CMI Distribution Maps of Plant Diseases
, No. 446). TRANSMISSION: Penetration of the fungus has been shown to occur (
in vitro
) through stomata and intercellularly. In the field disease entry can be facilitated by injury which is increased by slight freezing of the soil, a thick snow cover and slow melting of the snow in the spring. Sclerotia develop within the culms, digesting and to some extent incorporating the host tissue. Sclerotia may also be present on the leaves. Germination of sclerotia occurs to produce apothecia, with the subsequent production of ascospores which may then become the infective agents. The development of apothecia and the dissemination of ascospores are favoured by long, rainy autumns.

Abstract

A description is provided for
Lophodermella montivaga
. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS:
Pinus attenuata, Pinus contorta
. DISEASES: Needle-cast of pines. This fungus has been reported to have a 1-year life-cycle, with ascospores mature from July to October, and germinating by a short germ tube to produce an appressorium from which an infection peg was thought to penetrate the cuticle of new needles. In Colorado the first symptoms have been reported in September: the needles turned brown, and ascomata developed in them over winter. The influence of this species on individual trees and on stand growth has not been assessed. GEOGRAPHICAL DISTRIBUTION: USA (California, Colorado, Idaho, Montana, Oregon, Washington, Wyoming). TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract

A description is provided for
Lophodermella orientalis
. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS:
Pinus kesiya
. DISEASES: 'Yellow band' needle cast of pines. This disease was first encountered at two hardwood forest sites near Darjeeling, at altitudes of 1600 m and 2100 m above sea level, affecting
P. kesiya
in plantations 6 months, 18 months and 6 years of age. The proportion of trees infected varied from 20-80%, with up to 40% of the needles bearing lesions. Symptoms have been reported mainly from secondary needles and only occasionally from primary needles. They began as broad yellow bands up to 2 cm wide, later each with several large orange or brown elliptical spots which on microscopic examination were seen to be ascomata embedded in the needle. GEOGRAPHICAL DISTRIBUTION: India (West Bengal), Thailand. TRANSMISSION: By ascospores extruded in cirrhi in wet or humid conditions. This is a most unusual feature for members of the
Rhytismataceae
, which generally disperse by airborne ascospores. It is possible that this species may also disperse by airborne ascospores in conditions other than those in which it has been observed to date.
