Species Information
Summary:
Not available
Fruiting body: 2-8.5cm high, club-shaped, entirely tawny-brown to umber brown, fertile upper part about 0.8-1.5cm long, 0.3-0.5cm wide, one-fifth to one-half the total length, lanceolate, obtuse, slightly flattened, (Seaver), 1-7cm high, club-shaped, brown (wood brown to mummy brown when fresh), rarely black; spore-bearing upper part 0.2-1cm wide, 1/3 the length, compressed; fruiting bodies often white-powdery from white spores, (Mains)
Stem: 0.1-0.2cm wide in lower part, 0.2cm wide in upper part, short, or elongated and slender, round in cross-section; squamulose [finely scaly] especially in upper part, (Seaver), 0.1-0.4cm wide, round in cross-section, squamulose [finely scaly] especially in upper part, (Mains)
Microscopic: spores 65-105 x 5-7 microns, biseriate to multiseriate in the ascus, clavate-cylindric, straight, or curved, at first continuous and multiguttulate [with several droplets], then 3- and finally 7-12-septate, for a long time colorless, finally fuliginous; asci 8-spored, up to 150-175 microns long and 18-20 microns wide, clavate-cylindric, the apex narrowed, pore blue with iodine; paraphyses 5-6 microns thick, colorless, cylindric, not closely septate, usually strongly curved, or circinate [twisted around, coiled] in upper part, the apex abruptly elliptic to round thickened, (Seaver), spores (45)66-90(110) x 5-6 microns, clavate or clavate cylindric, "very variable in color and septation, hyaline and brown," spores of both colors discharged, hyaline non-septate, brown 0-13-septate, both with thin walls; asci 150-200 x 18-20 microns, clavate; paraphyses colorless and brown, "straight or considerably curved in upper part, remotely to moderately septate, not or slightly constricted at septa, with the lower cells cylindric, and the terminal clavate to obovoid, somewhat agglutinating.", (Mains)
Habitat / Range
single on clay or loamy soil in woods or on slopes of ravines, (Seaver), scattered to crowded on humus and rotting logs, (Mains)
Similar Species
The color is usually brown, rarely black, different from most other species, (Mains). Spores are both hyaline and brown whereas other species'' spores are brown, except for Geoglossum alveolatum of Michigan, New York and ?Idaho, and Geoglossum intermedium of ON, NY, TN, VA, which both have their colorless spores frequently septate, paraphyses agglutinated by amorphous matter, and stems tufted setose-hirsute instead of squamulose (G. alveolatum has spores mostly more than 66 microns long, and G. intermedium more than 66 microns long), (Mains). Geoglossum fallax has tawny-brown fruiting body, whereas Geoglossum glabrum, Geoglossum nigritum [here considered Geoglossum umbratile], and Glutinoglossum glutinosum have black or brownish black fruiting body, (Seaver). Trichoglossum hirsutum and Trichoglossum velutipes are hirsute from setae. See also SIMILAR section of Microglossum atropurpureum.
