Libextella Lonicexae, Clie. ^ Harlt. 
Sparsa, tecta, leviter bnllata, demirni pertiisa. Conidiis fusi- 
formibus arcuatis, continuis, hyalinis, in cirrbos pallidos emergenti- 
bus ('02 X '025 mm. long). 
On twigs of Lonicera. California (No. 2474). 
Dictyospoxiuxn cixcinatum, Cke. ^ Hark. 
Effusum, atro-fuliginosum, pulverulentum. Sporis subglobosis 
cordatisve, cellulosis (7-10) fuscis, cellulis globoso-compressis, 
circinatis, ut in Helicomatis simulantibus, absque liypliibus (sporis 
•035 mm. cellulis *01 mm. diam.). 
Oli decorticated (No. 2434.) 
Spores similar to those of Helicoma Berheleyi, but entirely with- 
out threads of any kind. A somewhat aberrant Dictyospormm. 
Dictyospoxium opacum, Cooke (i:; Hark. 
Maculeeforme, atrum. Sporis linguseformibus, applanatis, atro- 
fuligineis, subopacis (-05-*06 X -03-’035 mm.). Cellulis seriatis 
parallelibusque (circa *005 mm. diam.) compositis, numquam dis- 
silientibus. 
On culms of Typlia latifolia. California. (No. 2507.) 
Bactxodesmium opacum, Cke. Hark. 
Effusum, atrofuscum. Hyphis repentibus, sparsis, ramosis, 
septatis, flexuosis. Sporis assurgentibus, clavato-cylindraceis ; 
rigidis, sursum rotundatis, deorsum apiculato-attenuatis, atro- 
fuscis, opacis, multiseptatis (•! x *01 mm.') cellulis diametro 2-3 
pio. brevioribus. 
On cedar plank. California (No. 2363). 
Bactxodesmium clavulatum, Cke. Hark. 
Effusum, macul^forme, velutinum, atrum. Sporis clavatis, 
rectis, sursum rotundatis, deorsum in stipitem brevem attenuatis, 
4-5 septatis, atrofuscis (-045-’05 x *015 mm.). 
On bark of Eucalyptus. California (No. 1999, 2322). 
IMEystxospoxium tuxbinatum, Cke. & Hark. 
Effusum, velutinum, atrum. Hyphis brevibus, tenuibus, sub- 
simplicibus, septatis, plerumque sparsis. Sporis turbinatis, mox 
liberis, 3-5 septatis, superne rotundatis, obscurioribus, opacis, 
deorsum attenuatis, subhyalinis (*025-‘028 x '01 mm.). 
On decorticated Sequoia (No. 2495.) 
Spores broader than in M. aterrinum from which it differs also 
in not being densely fasciculate, and in the spores being soon de- 
ciduous. Quite distinct from Helminthosporium Arecce B. & Br. 
Helminthospoxium atxo-olivaceum, Cooke & Hark. 
Atro-olivaceum, molle, lanosum, effusum. Hyphis flexuosis, 
tenuissimis (*0025- ’003 mm.) intertextis, plerumque simplicibus, 
breviter septatis ; sporis clavatis ellipticisve, multe crassioribus, 
obscurioribusque, quinqueseptatis, fuscis (•02-'025 x -0075 mm.). 
On bark of Acacia. (No. 2328.) 
Threads very delicate and flexuous, not half the diameter of the 
spores, which latter are very numerous.
