FIELD BOOK OF COMMON GILLED MUSHROOMS 



crops follow from time to time whenever the weather is favor- 

 able. 



A few of the species continue in September. The latter 

 part of August and the first half of September will bring the 

 common mushroom and the horse mushroom, the weather 

 conditions being right. Excessively dry weather and prevail- 

 ing cold weather are unfavorable to mushroom growth. Heat 

 and moisture combined are favorable. It sometimes hap- 

 pens when the fields and open country are too dry for mush- 

 room growth, a scanty supply may be found in deep woods 

 and shady swamps. It would be useless to look in such places 

 for the common mushroom and the fairy-ring mushroom, 

 for they do not grow in woods; but the delicious lactarius, 

 the Involute paxillus and the Chantarelle may be found there. 

 The oyster pleurotus and the sapid pleurotus may be found 

 in woods or clearings at any time between June and October, 

 provided there is suflEicient rain to induce growth, but the 

 honey-colored armillaria, the imbricated tricholoma, the 

 masked tricholoma and the elm pleurotus will rarely be found 

 before the last week in August or the first of September. 

 These hints may be something of a guide to the inexperienced 

 mushroom hunter. The dates and habitat given under the 

 description of each species will furnish more full and definite 

 information on this subject.
