Abstract

Mycological Research News features: Numbers of insect and plant species.

Eleven papers are included in this issue. Ectomycorrhizal forests have been discovered in Guyana, and DNA profiles from forest soils demonstrate that ectomycorrhizal fungi are adversely affected by burning. Molecular and morphological studies have led to a reappraisal of the relationships and generic concepts of smuts on certain dicotyledons, and also of ‘subcentric’ Achlya species and allied fungi, leading to the recognition of a new genus.

Five papers concern the molecular characterization and variability of plant pathogens: Alternaria species-groups associated with core rot of apples; the identification of Verticullium longisporum on oilseed rape; Colletotrichum gloeosporioides on Stylosanthes species ; the transposa and vacuma groups of Botrytis cinerea; and Pyrenophora teres. In addition, phytotoxic metabolites have been identified in Sarocladium oryzae.

A revision of Dioicomyces (Laboulbeniales) is also presented and the following new scientific names are introduced: Newbya gen.nov.; Achyla truncatiformis, Dioicomyces denticulatus, D. ladoi, and D. leptalei spp. nov.; Colletotrichum gloeosporioides f. stylosanthis f. nov.; C. gloeosporioides f. sp. stylosanthis f. sp. nov.; N. apiculata (syn. Achyla apiculata), N. braziliensis (syn. A. braziliensis), N. curvicollis (syn. A. curvicollis), N. megasperma (syn. A. megasperma), N. oblongata (syn. A. oblongata), N. oblongata var. gigantea (syn. A. oblongata var. gigantean), N. oligocantha (syn. A. oligocantha), N. pascuicola (syn. Aplanopsis pasuicola), N. polyandra (syn. Achlya polyandra), N. recurva (syn. A. recurva), and N. stellata (syn. A. stellata) combs nov.
