	Ecology
		Orbiliomycetes occur on most of the dead branches of a tree from near the base up to the highest parts of the canopy.
		Xerotolerant species are not restricted to areas of low annual precipitation, they occur in nearly every plant community all over the world.
		Xerotolerant ascomycetes inhabit most kinds of exposed organic matter which rapidly dries down after rainy weather.

	GLOBAL VOICES OF SCIENCE: Protector of the Seeds: Seminal Reflections from Southern Africa -- Berjak 307 (5706): 47 -- ...
		Working with maize, we showed that individual fungal species, which continue to be metabolically active under storage conditions of high relative humidity, replace each other in a process of succession, all the while causing increasing damage within the seeds.
		We also established that xerotolerant fungi can be transmitted asymptomatically through the growing maize plant, even infecting the next seed generation.
		Of practical importance in rural Africa was the demonstration that thermotherapy--pre-storage immersion of maize grains for short periods in hot water--can substantially reduce fungal loads in maize seeds.

	Extremophile (Site not responding. Last check: 2007-10-26)
		For example, living in water saturated with benzene, or in the water-core of a nuclear reactor (see Deinococcus radiodurans).
		Xerotolerant: An organism capable of growth at low water activity.
		Some extremeophiles may fall under multiple categories, for example living inside hot rocks deep under Earth's surface.

	Mold: The Whole Picture Pt. 1
		There is some evidence that fungi are responsible for foxing on the paper of old books, despite the fact that the brown spots don't look like mold colonies.
		A reason offered for their drab appearance is that the dry interior of a book is not an ideal growth environment, even for xerotolerant or xerophyllic species.
		Indoor fungi are often xerotolerant or xerophyllic (tolerating or preferring low humidities), though the whole spectrum is present.

	Ecology
		Ecology of xerotolerant fungi, with special emphasis on Orbiliomycetes
		About 80% of the species of Orbiliomycetes grow on xeric (periodically dry) plant material.
		The ascocarps are xerotolerant as a whole, meaning that all parts survive complete drying down of their cells (poikilohydry).

		Antibiotic-supplemented media such as dichloran rose Bengal chloramphenicol agar and tryptone glucose yeast extract chloramphenicol agar are generally superior to acidified potato dextrose agar and other acidified media for enumeration of the vast majority of spoilage yeasts, particularly when cells are in a stressed condition.
		The recommended incubation temperature is 25°C, but incubation time between plating and counting colonies ranges from 5 days for determination of general populations of yeasts to 10 days for xerotolerant yeasts.
		New and improved media for selectively isolating various groups, genera, species and strains of yeasts capable of growing only under specific environmental conditions in specific types of foods and beverages are needed.

		It has a surface of 130 hectares, with the total presence of around 2.300 oaks (mainly Quercus Trojana Webb).
		This kind of oak is considered thermopile and xerotolerant, good for warm and dry weather, and it shows a high level of changes.
		Together with the typical Camus form, Gavoli found the macro acorn which does not exist in the Balkans.

	Podium Session 109: Environmental Microbiology
		An understanding of vapor drive and interactions with building materials is critical to the problem solving process.
		Case histories are presented to demonstrate how vapor drive can cause the growth of both xerotolerant and hydrophilic molds in buildings.
		Case studies show mold growth on the base of interior walls, in wall cavities, behind wallpaper and on subfloors.

		In the storage environment the relevant fungi are usually those species capable of growing in relatively dry conditions.
		Fungi that are able to grow in these conditions are termed "xerophilic" or "xerotolerant", depending on whether they grow best at relatively dry conditions (xerophilic) or whether they grow best at "wetter" conditions but tolerate dry conditions (xerotolerant).
		One complicating factor is that once growth is initiated (perhaps in a localised region of sufficiently high moisture content) the metabolic water produced by the growing fungus can perpetuate and amplify the process, and even allow the development of other, more moisture dependent fungal species.

		There are 4 basic classes of microbes in terms of tolerance and type of response to water potential stress
		E. More xerotolerant than either Class I or II Downshock not as severe, dehydration not as great
		Class I and II microbes maximize growth and sacrifice xerotolerance by not maintaining a low internal water potential

		I saw remnants of such VB-guttulation and also a yellow-orange colour in KOH near the tips of paraphyses, perhaps a result of oxidation of the VBs.
		The species is probably xerotolerant, not at all semiaquatic.
		Cyathicula (Crocicreas) ist von Hymenoscyphus vor allem durch das Gel und die Kristalle außen drauf geschieden.

	aspergillus
		Indoors it inhabits areas of high humidity like basements and cellars, it thrives on improperly stored foods, and it can live off duct particles rich in oragnic matter.
		It has been discovered that this genus is one of the most xerotolerant groups of fungi.
		Apsrergillus can withstand conditions of low moisture and extreme temperatures.
