Distr . — California ( Harkness , n. 1371). 
Most nearly allied to Vibrissea circinans , from which it is distin- 
guished by the shorter spores and pure white stem. 
Type specimens examined. 
Doubtful Species. 
Vibrissea vermicularis, Weinmann, Hym. Gast. Ross. 487, 1836. 
Simple, capitulum suborbicular, sublacunose, watery-pallid ; stem 
subterete, blackish-brown. 
Gregarious, stipes firmly attached, replete with a gelatinous mass 
when young, becoming partly hollow with age, generally cylindrical 
(very rarely attenuated towards the base or compressed), straight or 
curved, tough, smoky-black, paler below the pileus. Pileus \-2 lines 
broad, watery-pallid when young, then slightly tinged with blue. 
Hab.— On damp rotten wood of Aluus incana ? 
Distr. — Russia. 
Vibrissea rimarum, Fries , Syst. Myc. ii, 32, 1823; Sacc., SylL 
viii, n. 169, 1889. 
Subfasciculate ; yellow, head becoming tawny, stem compressed. 
Allied to the previous one [V. truncorum\ but truly distinct. Entire 
fungus, from the peculiar habitat, much compressed ; stem 1 inch long, 
thickness variable, flexuous, somewhat connate at the base. Cap 
hemispherical, small in proportion, becoming rufous, otherwise the 
entire fungus is yellow (Fries). 
Hab. — In cracks in old rotten worked beams. 
Distr. — Kamtschatka ( Wormskiold). 
Mitrula, Fries, emend. 
Ascophore erect, black or bright coloured, dry, or in some species 
slightly viscid when moist ; ascigerous portion clavate, subspathulate, 
or globose, often laterally compressed, and showing a distinct ten- 
dency to become decurrent down opposite sides of the stem, from 
which it is sharply differentiated, glabrous ; stem sometimes squamulose 
or pulverulent. Asci narrowly cylindric-clavate, apex narrowed or 
obtuse, pore blue with iodine in some species, not coloured in others ; 
spores hyaline, narrowly elliptical, septate, rarely continuous, 2 -seriate, 
rarely 1 -seriate ; paraphyses present.
