A RARE FUNGUS NEW TO CANADA 

 By W. S. Odell. 



While collecting fungi in the vicinity of Ot- 

 tawa during the past year, for the Victoria Memorial 

 Museum, one of the earliest forms found was the 

 edible morel, Morchella esculenta Pers. Shortly 

 after snow had left the ground and before leaves 

 appeared on the trees and shrubs, its dark olive 

 green or brownish cone was seen protruding a few 

 inches above ground. It is fairly common, growing 

 usually in damp situations, and lasts during May 

 and part of June if the weather is favorable. Any- 

 one who has seen this peculiar fungus w. remem- 

 ber and readily recognize it. It belongs to the order 

 Ascomycetes, family Helvellaceae, and differs from 

 mushrooms, puff balls, etc., in the manner in which 

 its spores are borne. In mushrooms the reproduc- 

 tive bodies called spores, are borne, four in number, 

 on ends of club-shaped bodies called basidia, cover- 

 ing both sides of the gills. The spores which are the 

 seeds of the mushroom, are of various sizes ; they 

 are microscopic, but may be seen en masse by 

 placing a specimen on black paper, tightly covered 



with a glass jar to prevent air currents. After a 

 few hours the paper will be covered with a whitish 

 deposit, which consists of spores in inconceivable 

 numbers. Spores are dispersed by the wind ; some 

 fall to the ground, and in process of time, it may be 

 months, often years, produce under proper con- 

 ditions, tiny thread-like jointed strands called 

 "spawn" by gardeners, which grow through the 

 substance on which the plant feeds. A familiar 

 form occurs in white mould often seen on vegetables 

 or on bread, and is better known as mycelium. It 

 may be found by digging up young mushrooms or 

 under matted leaves or in much decayed logs in 

 the woods, permeating every part. In fact the 

 mycelium is mainly responsible for the rapid decay 

 of wood, and causes much loss annually to standing 

 timber. 



While in the form of threads mycelium is the 

 vegetative stage of the mushroom. When the fruit- 

 ing stage begins, small knobs appear on these strands, 

 minute at first, varying from the size of a pinhead
