and almost smooth. Spores colorless by transmitted liglit, 

 granular, G — T^tin diameter. The fructifications of this species 

 are with us frequently large, in some cases, extending over an 

 area 20 — 30'™ long and several centimetres ^vide, with numer- 

 ous sporangia. 



A fairly common species found on the decaying wood of 

 various deciduous and coniferous trees. 



Family, TEICHIE.E. 



Capillitiimi consisting of free elaters or of tubules con- 

 nected to form a loose net with many free ends. The elaters or 

 tubules are marked with spiral thickenings. 



This family is represented in my collections by six species, 

 three of the genus HemitricJiia and three of the genus Trichia. 



Genus^ Hemitrichia Eost. 

 Capillitimn consisting of a net of branching anastomosing 

 tubules with many free ends, and marked with regular spiral 

 thickenings. 



32. Hemitrichia vesparium (Batsch) Macbr. — Sporangia 

 crowded, sessile, clavate, of a deep red color and with a metallic 

 lustre. Capillitium a loose net of orange colored threads about 

 0/A wide with numerous free ends. The threads are adorned 

 with a number of spiral bands and beset with numerous long- 

 spines. Spores yellowish by transmitted light, strongly warted, 

 10 — 11 /-t in diameter. 



On decaying Populus trenuloides. Rare. 



33. Hemitrichia stipata '(Schw.) Macbr. — Sporangia closely 

 ■crowded on a well developed hypothallus, stipitate, cylindrical 

 •or somewhat irregular from mutual pressure. Copper colored 

 and shining when fresh becoming dark red brown when old. 

 Total height about 1.5°^™. Stipe short, .S"'"^ in length, dark red 

 brown, striaite, hollow, filled with spore-like cells. The lower 

 ])art of the peridium persists as a plicate calyculus to which the 

 •capillitium is attached at a few points. Capillitium a loose net
