HEMIARCYRIA CHRYSOSPORA, Lister. 
A form of Hemiarcyria , which appears not to have been hitherto 
described, was sent to me by Mr. Henry Munro, of the Gardens, 
Clevelands. Lyme Regis, on Dec. 4, 1886. 
He found it in mature condition, on twigs of larch, lying on the 
ground, and on the surrounding herbage. 
The sporangia are sessile, about 1 mm. in diameter, spherical, 
and generally closely aggregated, of a bright ochraceous yellow, 
resembling those of Trichia chrysosperma ; the walls of the sporan- 
gia are membranous. 
The yellow capillitium is a loosely formed net of spiral threads, 
5 mk. in breadth, with many free ends, which terminate, as a rule, 
in slightly expanded conical apices ; it is attached at numerous 
points to the basal wall of the sporangium. 
The spirals, usually four in number, are closely arranged, and 
are connected by less prominent transverse processes, nearly at right- 
angles to the line of the spirals, and at distances about equalling 
that of the spirals from each other, giving a more chequered ap- 
pearance than that exhibited by the longitudinal strise of Trichia 
chrysosperma. 
The bright yellow spores are 16 mk. in diameter ; the central 
portion is surrounded by a hyaline coat 3 mk. in thickness, which 
is divided into about twenty polygonal areas ; they bear a near 
resemblance to those of Trichia chrysosperma , a species which 
seems to be rare in this country, and for specimens of which I am 
indebted to Prof. Bayley Balfour. 
The organism under consideration, except for the absence of free 
elaters, resembles in the closeness of the spirals and the diameter 
of the threads, robust specimens of Trichia affinis , which is abun- 
dant in our woods in late autumn, but the spores are markedly 
different, being considerably larger, with no appearance of pitting 
on the ridges, and with a thicker reticulated envelope. 
The reticulation is even more brightly defined than in the spores 
of Trichia chrysosperma.

Waste Paper. — Our readers should look out for another new 
book, which professes to be a “ Field Book for Fungus Hunters,” 
but is really only a hunter for their spare coppers. “ Please pity 
the poor blind ! ”
