6. Geoglossum intermedium Durand, Ann. Myc. 6: 431. 1908. 



Ascophores solitary, black, 3-4.5 cm. high; ascigerous por- 

 tion one-fourth to one-third the total length, oblong to ovate- 

 lanceolate, compressed, obtuse or rounded above, usually 

 abruptly narrowed to the stem below, .75-1.5 cm. long, 2-6 mm. 

 broad, the hymenium prettily alveolate when dry, the meshes 

 less than .5 mm. across; stem slender, terete, usually more or less 

 flexuous, brownish-black, .75-1 mm. thick, nearly smooth below, 

 provided toward the top with slender, flexuous, sparingly septate, 

 obtuse, brown hairs, up to 100 /z long; asci clavate-cylindric, very 

 short-pediceled, apex narrowed but rounded, reaching a length 

 of 150-200 n and a diameter of 20 n, pore deep-blue and entire 

 ascus slightly blue with iodine, 8-spored; spores multiseriate, 

 stout, clavate, but not much narrowed toward the lower end, 

 ends rounded, somewhat curved, at first hyaline, becoming 1-3- 

 septate, finally rather pale-brown, 7-1 1-septate, 6 X 55-75 /x; 

 paraphyses cylindric, nearly or quite hyaline, straight or only 

 slightly curved above, sparingly septate, very gradually and 

 slightly thickened upward, the apex tending to become pyriform 

 to globose thickened, the apical portion of the asci and paraphy- 

 ses agglutinated by an amorphous brown mass. 



In swamp and on rotten wood.

Ascophores solitary, or gregarious, with the aspect of G. 

 glabrum, slenderly clavate, 1.5-5 cm. high; ascigerous portion 

 about one-third the total length, lanceolate, obtuse, compressed, 

 black, 4-12 mm. long, 3-4 mm. thick, when moist with an even 

 surface, which on drying often becomes pitted or distinctly 

 ridged in an alveolate manner; stem slender, terete, 1-2 mm. 

 thick, slightly thickened upwards, distinctly squamulose or 

 hairy; flesh black, composed of a fascicle of parallel, septate 

 hyphae 8-10 m in diameter, the ectal ones of the stem being 

 produced to form slender, brown, flexuous, obtuse, septate hairs 

 up to 125 /i long; asci clavate-cylindric, apex slightly narrowed 

 but rounded, pore blue with iodine, reaching a length of 150- 

 170 /i and a diameter of 15 /x, 8-spored ; spores fascicled, or multi-
