Publisher's Synopsis
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1919 edition. Excerpt: ...changed to Geoglossum atropurpureum. I have no specimens. ILLUSTRATIONS.--But two colored figures have been given from the growing plant vii.. Holm's (as Clavaria mitrata a), and Persoon Obs. 2, t. 3. f. 5. Batsch's figure is crude and doubtful, probably Clavaria pistillaris, and Cooke and Massee's are dried specimen products. GEOGLOSSUM ROBUSTUM.--This is a rare American species, differing from the preceding in darker color, brown, almost black, no purplish tint, larger spores, 4-6 x 25-50, and paraphyses with bent apices, and epithecium thin and not conspicuous. As both species become black in drying, dried specimens, I judge, arc difficult to distinguish. I have a specimen from Geo. L. Morris, Massachusetts. GEOGLOSSUM ARENARIUM.--A boreal species known only from very northern localities, Greenland, Labrador and Newfoundland. It is only known from dried specimens, which are black, but the spores are the same type as the preceding species, and the color of the fresh plant is no doubt dark brown. Spores 6 x 25-35, hyaline, continuous. Paraphyses brown, cylindrical, longer than the asci, the apices clavate, thickened and curved. The dried specimens can be readily distinguished by the peculiar paraphyses. SECTION 2.--Black Geoglossums with colored, septate spores. Black GeoHlossums are readily divided into three subsections, from characters of the fresll plant: 1st. Viscid. 2nd, Not viscid, smooth or merely clammy. 3rd, Hirsute. VISCID, BLACK GEOGLOSSUMS. GEOGLOSSUM GLUTINOSUM--Plants black, viscid. Fertile portion compressed, not sharply distinct from the stem. Stem slender, smooth, viscid. Spores cylindrical, dark, 5-6x60-100, 3 to 7 septate. Paraphyses (Fig. 782) cylindrical, exceeding the asci, with brown, abruptly piriform or globose...
