Glossary – E

echinate – covered with short spines.

echinulate – regularly roughwalled, covered with minute spines.

ecological strategy – life cycle optimised by vector/reservoir relations for survival of the species in a particular habitat.

ecology – science focussing on the natural behaviour of fungi.

effuse – thin and widely spreading.

ellipsoidal – threedimensionally bilaterally symmetrical, l:b about 1:2; in broadly ellipsoidal l:b is about 1:1.5.

encephalitis – inflammation of the white substance of the cerebral hemispheres, with as main symptoms fever, headache, photophobia with weakness, seizures, and less commonly nuchal rigidity, stiffness of the limbs, slowness in movement, clumsiness, drowsiness and coughing.

endocarditis – acute or chronic inflammation of the inner membrane that lines the cavities of the heart.

endoconidia – plural of endoconidium, asexual propagule formed inside a cell.

endoconidium (plural: endoconidia) – asexual propagule formed inside a cell.

endogenous – developmental process taking place inside a cell.

endophtalmitis – inflammation of the tissues within the eye.

endoplasmic reticulum – cytoplasmic network of membranes bearing ribosomes.

endosaprobe – fungus feeding on the contents of the intestinal tract.

endosporulation – conidia formed inside a cell by wall formation around parts of the cytoplasm.

enteroarthric – disarticulation of hyphae into conidia by which the viable cells form an extra, internal wall layer and intermediate cells collaps after autolysis, promoting liberation of the conidia.

enteroblastic – inflation of conidium initial involving the inner wall layer through the outer wall layer of the mother cell.

environmental pathogen – pathogen with a saprobic and a pathogenic life cycle, infectious propagules being infectious and without hosttohost transmission.

epitheton – speciespart of a fungus name.

erumpent – bursting through the surface (e.g. of leaves, in plant pathogens).

euseptate – conidia subdivided by true septa involving all wall layers.

evanescent – rapidly dissolving.

exogenous – formed outside a cell, mostly on short branchlets.

expanding – with rapid growth rate, colony attaining at least 4 cm diam in 14 d.

extremophily – preferred growth under extreme environmental conditions, poor or no growth under routine conditions.

extremotolerance – tolerating extreme environmental conditions but also with good growth under routine conditions.

exudate – droplets produced on the surface of a colony.
