 conidia brown, then blackish olive, roundish, not pedicellate, pluri- 

 cellular, punctato-granulose, 20-28 /x diam.

 Oak (St.), April. Stromata bright (gamboge) yellow, then dull 

 yellow, at last brown, somewhat sanguineous at the very base, 

 seriate and confluent between the nerves. The pulverulent look 

 arises from the non-compact basidia. The spores are elliptical or

Catharinea Dixoni Braithw. MS. Description: — In small tufts; 

 dark green. Ehizome tomentose. Stems erect, simple, about one 

 inch high, naked below. Leaves lax below, rather crowded above; 

 slightly sheathing, concave, keeled ; erecto-patent when moist, 

 crisped when dry. Lowest small, scale-like, ovate, apiculate, entire ;

 from the base ; not spinulose at the back. Cells larger and more 

 regularly quadrate than in (_'. nndnlata, quadrate below, quadrate- 

 hexagonal above and rounded, especially towards the apex and 

 margin ; arranged in longitiulinal rows in the disk of the leaf, more 

 irregular and smaller towards the margin ; chlorophvllous above,
