Dematieae. 
Amerosporae. Trichosporium insigne, sp. nov. (Fig. 33). 
Caespitulis minutis atris ; hyphis vage ramosis intertextis septatis 
hyalinis 4-5 /* crassis, conidiis apice ramulorum oriundis perfecte 
globosis verrucosis ex hyalino aterrimis opacis 25-35 ft diam. 
Hab . — On Pigeons' dung, Kew, Nov. 1900. 
Allied to S. sphaericum , Sacc., from which the present species is 
distinguished by the hyaline hyphae and the larger waited conidia. 
Trichocladium asperum, Harz (Fig. 69). 
T.asperum, Harz, in Bull. Soc. Imp. Nat. Moscou, xliv, 125, Tab. 2, 
f. 1 (1871); Sacc. Syll. Fung, iv, 376 (1886). 
Forming minute patches ; mycelium creeping, colourless, sparsely 
septate, branched ; conidiophores very short, suberect or decumbent, 
simple, each bearing a single conidium at the apex ; conidia didymous, 
oblong, rounded at the apex, 18-22 x 12-13^, slightly constricted at 
the septum, cells about equal, or the lower one slightly smaller, when 
young colourless and smooth, becoming dark brown and subopaque, 
with the epispore of both cells covered with minute scattered warts. 
Hab . — On Rabbit-dung, Kew, Jan. 1901. (Distrib. — Austria and 
Germany, on wood.) 
The upper cell of the conidium, which is usually, at any rate in the 
young stage, the larger, becomes warted first. Harz ( 1 . c.) suspects 
that the present Fungus may be the Sporidesmium asperum of Corda, 
Ic. Fung, ii, 6, Taf. 8, f. 27 (1838). 
Cladosporium herbarum, Link; Sacc. Syll. Fung, iv, 350 (1886) ; 
Mass. Brit. Fung. FI. iii, 394 (1893). 
Hab . — On Goose-dung, Kew, Jan. 1901. 
Marchal (in Bull. Soc. Roy. Bot. Belg., xxiv (1), 67 (1885)) makes 
a forma fimicola (raised to varietal rank by Saccardo in the ‘Sylloge’) 
of this species when growing on dung, but our specimens differed in 
no way from the type. 
Dietyosporae. Sporodesmium piriform©, Corda (Fig. 52). 
S.pir iforme, Corda, Icon. Fung, i, 7, f. 116 (1837); Sacc. Syll. 
Fung, iv, 502 (1886) ; Mass. Brit. Fung. FI. iii, 426 (1893). 
Hab . — On Rabbit-dung, Mulgrave Woods, Yorks., Sept. 1900. 
The conidia are variable in size and form, but always more or less 
piriform, and attached by a broad truncate base. There are usually
