| 例句 | Ascomycetes have both sexual and asexual life cycles. Fundamentals of Biology 2015-01-01T00:00:00Z It is also possible in the absence of satisfactory intermediate forms that the Ascomycetes and Basidiomycetes have also been derived from the algae independently of the Phycomycetes, and perhaps of one another. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z These latter are thus seen to be carpospores, comparable to those of Red Alg�, and to the ascospores of Ascomycetes. The New Gresham Encyclopedia. Vol. 1 Part 3 Atrebates to Bedlis Cooke says they appear to be the link which unites the Basidiomycetes to the Ascomycetes by means of the Tuberacei or genuine Truffles. Student's Hand-book of Mushrooms of America, Edible and Poisonous The structure of the remaining Ascomycetes can be studied under two groups, i.e., the fleshy Ascomycetes, or, as they have been termed, the Discomycetes, and the hard, or carbonaceous Ascomycetes, sometimes called the Pyrenomycetes. Fungi: Their Nature and Uses Ascomycetes not only infest and destroy crops directly; they also produce poisonous secondary metabolites that make crops unfit for consumption.

Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z The Ascomycetes often include among their numbers fungi ranging in size from microscopic one-celled plants to quite large and very beautiful specimens. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth In Plates C and D are figured 9 types of edible fungi included in the family Ascomycetes, sub-family Discomycetes. Student's Hand-book of Mushrooms of America, Edible and Poisonous Asci formed from the fertile cells of a hymenium Ascomycetes. Fungi: Their Nature and Uses The last group of the Ascomycetes are the “black fungi,” Pyrenomycetes, represented by the black knot of cherry and plum trees, shown in Figure 46. Elements of Structural and Systematic Botany For High Schools and Elementary College Courses The Ascomycetes, at least the Carpoascomycetes, exhibit a well-marked alternation of sexual and asexual generations. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z Another very large group of fungi is the Ascomycetes, or sac fungi. The Mushroom, Edible and Otherwise Its Habitat and its Time of Growth Changed "Basidyomycetes" to "Basidiomycetes" on page 18 of part 3: "Ascomycetes and Basidiomycetes." Student's Hand-book of Mushrooms of America, Edible and Poisonous The number of sporidia contained in an individual ascus is usually less than in the majority of the Ascomycetes, and the sporidia approximate more nearly to the globose form. Fungi: Their Nature and Uses Ascomycetes, or “Spore sac fungi,” where the spores are produced in delicate sacs called asci. Among the Mushrooms A Guide For Beginners The same functions of storage in advance of fructification are also exercised by the stromata so common in Ascomycetes. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z In this point and in their method of fertilization the Laboulbeniineae suggest a possible relationship of Ascomycetes and the Red Algae. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z The family Ascomycetes is rich in genera and species. Student's Hand-book of Mushrooms of America, Edible and Poisonous The Ascomycetes contain an immense number of species, and in general terms we might say that they are found everywhere. Fungi: Their Nature and Uses Ascomycetes.—This, except in the case of a few of the simpler forms, is a very sharply marked group characterized by a special type of sporangium, the ascus. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z The group of the Hemiasci was founded by Brefeld to include forms which were supposed to be a connecting link between Phycomycetes and Ascomycetes. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z Invisible to the microscope, but rendered visible by reagents, are glycogen, Mucor, Ascomycetes, yeast, &c. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z They are nearly the equivalent of Basidiomycetes and Ascomycetes. Student's Hand-book of Mushrooms of America, Edible and Poisonous In systematic works, these are included under two orders, the Physomycetes and the Ascomycetes. Fungi: Their Nature and Uses The following are the technical characters of the family:— Fruit consisting of sporidia, mostly definite, contained in asci, springing from a naked or enclosed stratum of fructifying cells and forming a hymenium or nucleus = Ascomycetes. Fungi: Their Nature and Uses The sporangium with its endogenous spores has been compared with an ascus, and on these grounds the group is placed among the Ascomycetes—a very doubtful association. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z De Bary thinks that he is authorized in assuming the probability that the conceptacles and organs of fructification of others of the Ascomycetes, including the Discomycetes and the Tuberacei, are the results of sexual generation. Fungi: Their Nature and Uses There are also presented, in plates C and D, illustrations of nine species comprised in four genera of the sub family Discomycetes, of the family Ascomycetes. Student's Hand-book of Mushrooms of America, Edible and Poisonous But in all there is this important difference from the Ascomycetes we have already had under consideration, that the hymenium is never exposed. Fungi: Their Nature and Uses The Ascomycetes are represented everywhere, and although certain groups are more tropical than others, they are represented in all collections. Fungi: Their Nature and Uses Carpoascomycetes.—The other divisions of the Ascomycetes may be distinguished as Carpoascomycetes because they do not bear the asci free on the mycelium but enclosed in definite fruit bodies or ascocarps. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 "Frost" to "Fyzabad" 2011-08-15T02:00:28.473Z All these collections contain coriaceous species of Polyporus, Favolus, and allied genera, with Auricularini, together with such Ascomycetes as Xylaria, and such forms of Peziza as P. tricholoma, P. Hindsii, and P. macrotis. Fungi: Their Nature and Uses Ascomycetes.—In the plants of this family the spores are not supported upon basidia, but instead are enclosed in minute sacs or asci formed from the fertile cells of a hymenium. Student's Hand-book of Mushrooms of America, Edible and Poisonous In the last family, the Ascomycetes, we shall meet with a very great variety of forms, all agreeing in producing sporidia contained in certain cells called asci, which are produced from the hymenium.
