6 MR. W. PHILLIPS ON THE GENUS VIBRISSEA. 
paraphyses numerous, branched, very slender, septate, enlarged a little at the summits, 
which are slightly coloured. When removed from the water, and exposed for a short 
time to the air, the sporidia shoot out from the hymenium with more or less violence, 
many of them remaining attached by one extremity to the hymenium, waving to and fro 
like floss silk, glistening in the light. 
On decayed wood (Alder, Birch, Pine, &c.) in subalpine streams. Rare. Capel Curig, 
North Wales; Scotland; South of France; United States of America.

Simple; head orbicular, orange-vermilion, margin hispid; stem cylindrical, hirsute 
with black articulated hairs, internally whitish cinereous. 
On dead sticks of heather in a pool of water on Mor Shron, Braemar, at an altitude of 
2200 feet. September and October 1873. 
* The stems are simple, varying from 2 lines to $ an inch in height, springing from 
complicated threads, and covered with black-jointed hairs or fibres ; at the junction with 
the head the stem is less hairy and paler in colour; internally it is solid and greyish- 
white. The head is flattened orbicular (sometimes concave in the middle), and of a 
beautiful orange-vermilion in colour; the margin has a fringe of close appressed hairs of 
the same character as those on the stem; underneath the head is paler in colour at the 
junction with the stem. Тһе species is readily distinguished from its ally, V. truncorum, 
by the hairy stems and differently coloured heads."— Dr. Buchanan White. 
3. VIBRISSEA RIMARUM, Fr. Sys. Myco. ii. p. 32. 
Subfasciculate, yellowish, capitulum becoming tawny, stem compressed. 
Allied to V. truncorum, but really different. Substance dry but fleshy. The whole 
fungus, from the peculiar station, greatly compressed; stem 1 inch long, of variable 
thickness, flexuose, subconnate at the base; capitulum hemispherical, comparatively 
small, darker, at length rufous; but the whole fungus yellow. 
On chinks of beams and other old wood used in the building of domestic houses.

Assuming that specimens of this species exist in the herbarium of the illustrious Fries, 
it would be highly interesting to submit them to a careful microscopical analysis to 
determine the structural differences between it and its allies. There is so wide a 
difference in the conditions of growth that one is tempted to doubt this being a true 
Vibrissea, nothing being said to indicate its aquatic habit. I have included it, however, 
although it does not accord with my definition of the genus, leaving it open for future 
investigation.
