Mucronella calva reproduced from Smith. 



MUCRONELLA CALVA. (Fig. 726.) Teeth slender, scat- 

 tered, from a quarter to an inch long, whitish, then grey. Subiculum 

 (teste Smith) a very thin film that soon disappears. This is un- 

 known to me excepting from the books. I reproduce Smith's figure, 

 which I judge is correct as to general appearance and more char- 

 acteristic than the original by A. & S. Fries got an impression that it 

 had one spore basidium, and Smith improved on it by assigning " 1 to 

 4" spores, and draws his figures to show it, an obvious bull on the face 

 of it. Men who draw figures of ideas instead of facts are always 

 making such breaks. While I have never seen the plant, I surmise 

 that it is a Calocera and that its basidia will be found to be furcate, 

 but if the basidia are clavate as Smith shows them, then the plant is 

 a better Pterula. The name calva means a bald head with a few 

 scattered hairs, and from Smith's figure seems quite appropriate to 

 the plant. 



SECTION 2ND. TEETH FASCICULATE AT BASE. 

 I believe this section is better classed as Pterula. 



MUCRONELLA FASCICULARIS. (Fig. 727.) Teeth slen- 

 der, caespitose-fasciculate from a common base, pendant, drying 



reddish, about a cm. long. Spores 

 hyaline, globose, 8-10 mic., apicu- 

 late. This was figured by A. & S. 

 many years ago. I have seen it 

 rarely in the museums, but have no 

 specimens from Europe or the United 

 States. I collected it in Samoa, and 

 my specimens were described as 

 Pterula fascicularis (Myc. Notes, p. 

 50). I do not question that it is the same as the European plant. At 

 least it agrees well with the original figure. It appears to be very 

 rare in Europe and has been recorded from the United States. I be-
