Tichothecium, Arnold. 
P/ueospora triseptata, Hepp. 
On thallus of Lecidea albo-atra, v. epipolia, Ach. (Mudd) ; 
L. petrcea, v. concentrica, Dav. ; and other crustaceous Lichens 
(Korb.). 
Spores 8, small, ovoid-oblong, 4-locnlar, brown. 
4. M. peripherica, Tayl. ; Mudd, 308. 
Though described by Mudd as having a proper thallus, is 
probably parasitic on the sterile thallus of Lecanora glau- 
coma or other crustaceous Lichens. 
Spores 8, fusiform, 4-locular, brown. Mudd suggests that 
it may be a Spfueria. 
5. M. verrucosaria (Mudd, 165). 
On thallus of Lecanora vemicosa. 
Spores 8, ovoid-oblong, 2-locular, colourless. Mudd (who 
suggests it may be really a Fungus ) describes it without 
giving it a name ; it is, however, convenient, if not necessary, 
for future reference, that it should bear some name, and 1 
have therefore placed it provisionally here, regarding the 
genus Microthelia 2 as both a provisional and heterogeneous 
one.

On apothecia of Parmelia perforata. 
Spores spherical, simple, brown.

Spores unknown.
