68 Mas see. — A Monograph of 
falling away the peridium presents a tessulated appearance as 
in L. Hoy lei. 
Lyeoperdon Hoylei, Berk. (Fig. 68). Peridium sub- 
globose, densely covered with stout, long, pyramidal, purple- 
brown, deciduous spines, which become smaller and paler in 
colour on the stout stem-like base ; between the spines are 
minute, brown, persistent warts ; mouth small, irregularly 
torn ; root of long white fibres. Capillitium dense, contin- 
uous with the compact, bright-olive sterile base, thickest 
threads wider than diameter of spores, sparsely branched ; 
spores bright lilac, becoming tinged with purple, globose, 
minutely warted, often furnished with a long hyaline pedicel, 
5 n diam.

Peridium 1-2 in. across ; stem-like base \~i in. long, § in. 
thick, sometimes almost obsolete. The spines are frequently 
curved, and exhibit a tendency to split up in a fibrillose 
manner from the base. When the spines fall away the peri- 
dium presents a tessulated appearance owing to the dark 
persistent minute warts which surround the pale scars left 
by the fallen spines. Resembling L. echinatnm in general 
appearance, but readily distinguished by the compact, non- 
cellular, bright-olive sterile basal portion, which is produced 
into a stem-like base, and size and colour of the spores. 
Lyeoperdon atropurpureum, Vitt. (Fig. 71). Subglobose 
or pyriform, sessile or with a short stem-like base, plicate 
below; peridium thin, flaccid, covered with brownish slender 
spines, becoming glabrous above, dehiscing by a minute 
irregular mouth. Capillitium continuous with the well-de- 
veloped cellular sterile base ; spores blackish purple, spherical, 
warted, sometimes pedicellate, 6-7 ju, diam,
