BERKELEY'S TYPES OF FUNGI. 99 
at other times this structure is entirely absent. Externally and 
the margin quite glabrous, the whitish pulverulent external 
appearance noted by Berkeley being due to the collapse of the 
external cells during drying. Thefungus is a true Mollisia, and 
will stand as MoLLISIA ALLIGATA. 
Peztza (Mountsta) PERISTOMIALIS, Berk. § Broome, in Ann. § 
Mag. Nat. Hist. Ser. U1. xviii. (1856) p. 126, pl. 5. fig. 32. 
Ascophore subcylindrical, base somewhat narrowed, solid, 
glabrous except the margin, which is surrounded by 10-18, 
spreading, white, acuminate teeth, each consisting of a fascicle 
of slender hyphe; 25-35 p long, by 8-10 » broad at the base, 
whitish; dise plane, about 4 mm. high, and not quite so much 
across ; hypothecium and excipulum composed of aseptate, 
hyaline hyphe very intricately interwoven ; the cortex is similar, 
and the hyphe run out to form the marginal teeth ; asci broadly 
clavate or fusoid, widest portion sometimes above, sometimes 
below the middle, apex narrowed, base stout, about 85-90x 
124; spores obliquely 2-seriate, smooth, hyaline, narrowly 
elliptical or sometimes almost eylindrical, ends rather acute, 
straight or very slightly curved, at first multiguttulate, then 
distinetly 3-septate, 30-85 x 5 «; paraphyses absent. 
Mollisia peristomialis, Phillips, Brit. Disc. p. 201, pl. 6. f. 37. 
Cyathicula peristomialis, Sacc. Syll. viii. n. 1284; Massee, Brit. 
Fung.-Fl. iv. p. 273 (peristomalis). 
On dead bark of holly. England. ; 
A most exquisite object under a moderate magnifier, resembling 
some Actinia in miniature (Berk. g Broome). 
Gregarious, subglobose, and closed at first, then becoming 
elongate and more or less cylindrical, the base often slightly 
narrowed, but constantly sessile, apex truncate ; disc not 
depressed, surrounded by acute, spreading teeth like the peri- 
stome of a moss. Allied to the genus Belonidium in the 3- 
septate spores, but the sum of characters point to the genus 
Cyathicula. 
Prziza (Montista) apicatts, Berk. f Broome, in Journ. Linn. 
Soc., Bot. xiv. (1875) p. 106. (PI. 4. figs. 23-24.) 
Solitary, or usually in clusters of 2-4, sessile, subglobose and 
closed when young, then cup-shaped, often irregular from lateral 
pressure, j-3 mm. across, pale orange ; externally very minutely 
pulverulent, due to the free ends of the parallel rows of hyphx
