teliospore = a thick-walled resting spore <strong>of</strong><br />
rusts and smuts in which karyogamy<br />
occurs; it is part <strong>of</strong> the basidial apparatus<br />
thallus = a relatively simple plant body devoid<br />
<strong>of</strong> stems, roots, and leaves; in<br />
fungi, the somatic phase (pl. thalli)<br />
therapy = treatment <strong>of</strong> disease<br />
treatment = mode <strong>of</strong> dealing with a person<br />
or thing; more specifically, intervention<br />
in the natural process in order to reduce<br />
disease<br />
tretic (conidiogenous cell) = apparently<br />
enteroblastic, protrusion <strong>of</strong> the inner<br />
wall taking place through one channel<br />
or several channels in the outer wall.<br />
The channels (or pores) can be seen<br />
quite easily with an ordinary compound<br />
microscope and although some recent<br />
electron microscope studies indicate<br />
that conidium development is not necessarily<br />
strictly enteroblastic, their presence<br />
provides a character most useful<br />
to taxonomists. The continued use <strong>of</strong><br />
the term tretic is recommended.<br />
tubercle = wartlike growth<br />
verrucose = warted<br />
verruculose = finely warted<br />
verticillate = arranged in whorls<br />
wart disease = (<strong>of</strong> potato) caused by<br />
Synchytrium endobioticum<br />
zygospore = a resting spore that results<br />
from the fusion <strong>of</strong> two gametangia in<br />
the Zygomycetes<br />
a Adopted from Zadoks and Schein (1979).<br />
Allexopoulus and Mims (1979). Ellis (1976).<br />
Neergaard (1979), Ainsworth and Bisby (1971).<br />
