11 and \'l subociual, l\w latter somewhat shorter; eell 1\' abruptly 

 prominent externally helow tiie insertion-cell. Insertion-cell deeply 

 suffused, rather thick; the basal cell of the outer appendage somewhat 

 smaller than that of the inner, externally opaque, bearing distally two 

 branches radially placed; the outer branch strongly divergent to 

 liorizontai or e\"en slightly recurved, almost wholly opaque, its opacity 

 continuous with that of the basal cell; bearing al)ove several subhya- 

 line branchlets; the inner branch erect, once or twice branched, its 

 basal cell and the outer primary- branchlet arising from it, more or less 

 deeply suffused externally: basal cell of the inner appendage slightly 

 longer than that of the outer, bearing two erect slightly olivaceous 

 branches, one on either side, which are usually twice branched; the 

 ultimate branchlets hyaline, rigid, bluntly tipped, the longest scarcely 

 reaching the tip of the perithecium. Body of the perithecium slightly 

 and more or less evenly inflated, broadest in the middle, rich amber 

 \cllow, sometimes becoming tinged with olivaceous; usually, l:)ut not 

 in\ariably, twisted one quarter, so that the tip is viewed at right angles 

 to the normal position; the tip more or less deeply suffused with black- 

 ish olive, short, rather abruptly distinguished, bent distinctl}^ inward, 

 its outer margin nearly straight, its inner strongly indented, the apex 

 usually broad, horizontal, symmetrically bilobed; the lip-edges hya- 

 line and evenly rounded ; if the twist is absent, oblique, or sometimes 

 four-lobed if the twist is one eighth. Spores 78X7^, Perithecium 

 125-145X35-40 ju. Receptacle 100-135 yu. Total length to tip of 

 perithecium 225-275 fx, average 250 //•

This species does not appear to be nearly allied to L. fumosa to 

 which it has been referred by Spegazzini who found it on "Argutori- 

 dius" at Santiago, Chile. It was found by me on the same host at 

 the Banos de Apoquindo, near Santiago. 



Laboulbenia asperata nov. sp. 



Hyaline becoming pale straw- or amber-yellow. Receptacle 

 normal, the subbasal cell variabl}^ elongated, rarel}' minutely corru- 

 gated; cell V parallel to cell IV and slightly longer. Appendages 

 hyaline, the insertion-cell transparent, faintly suffused with reddish, 

 the basal cell of the outer appendage usually distinctly larger than 

 the inner, broader than long and forming a more or less prominent
