Autumn, as our gathering here year by year shows, is the season, of course, 

 in which the majority of the larger fungi appear. The soil, warmed by the sum- 

 mer sun, quickens, and brings to maturity the mycelium, which has been growing, 

 and developing under its influence, in the more shady, and damper situations of 

 our woods and fields. A hot and sunny autumn, with occasional warm thunder 

 showers, succeeding to a warm summer, is the most favourable season to their 

 growth ; as the ground becomes thoroughly warmed by the sun, so that the rain, 

 when it falls, nourishes the mycelium, and evaporating quickly has not time to 

 chill the ground, and so check the tender rootlets. 



After a cold and wet summer, the mycelium growth is retarded, and it 

 cannot properly develope, or mature, so that many species are absent, and many 

 specimens found are ill-gi'own, and stunted, from want of sufficient warmth. 



Several, however, of the Hymenomycetes, and other families, I have noticed 

 only in vtdnter, and early spring, so that this explanation cannot apply to them. 

 The following are those, most of which, I have more than once found at these 

 periods of the year :— Ag. (Trieholoma) gambosus (April and May), Ag. (Pleu- 

 roiMS j subpalmatus (Jan.), ostreatus (Mar., Nov., and Dec), atro cceruleus (Jan), 

 Ag. (CollyUa) velutipes (Dec. and Jan.), tenacellus (Jan. and Mar.), Ag. (My- 

 cena) polygrammus (Jan.), alcalinus (Jan.), galopus (Dec), Ag. (Claudopus) euos- 

 mus (Jan.), Ag. ( Phol iota ) prsscox (Feb.) Ag. (Flammula) flavidus (Jan.), hy- 

 bridus (Dec), sapineus (Jan.), Ag. (Crepidotus) mollis (Dec), Ag. (Navcoria) 

 semiorbicularis (Jan.), Ag. (Galera) tener (May), Ag. (Tubaria) furfuraceus 

 (Feb.), Ag. (Stropharia) aeruginosus (Dec), Ag. (Hypholoma) fascicularis (May), 

 Ag. ( Psathyrella) ^v&cWin (Apr.), disseminatus (Jan.), Coprinus comatus (Feb.), 

 micaceus (Feb.), deliquescens (Feb.), Lepista nuda, (Dec), Hygrophorus hypothejus 

 (Dec), russo coriaceus (Dec), Cantharellus aurantiacus (Dec), muscigenus (Dec), 

 Marasmius ramealis (Dec), Panus conchatus (Jan.), stypticus (Jan.), Trogia 

 crispa(Dec.), iewziies betulina (Feb.), flaccida (Mar.), Polyporus hramsXis {Dec. 

 and Jan.), leptocephalus (Dec. and Feb.), fumosus (Feb.), adustus (Dec, Feb., 

 and Apr.), crispus (Feb.), amorphus (Dec. and Jan.), fomentarius(Dec.), conchatus 

 (Jan.), ulmarius (Mar.), fraxineus (Mar.), annosus (Jan. and Mar.), versicolor 

 (Feb.), abietinus (Feb.), ferraginosus (Dec), vitreus (Mar.), Tramefes pini (Dec), 

 suaveolens (Mar. and Apr.), ZJcrrfaZfa quercina (Apr.), confragosa (Feb.), unicolor 

 (Dec), Merulius tremellosus (Dec), corium (Dec, Feb., and Apr.), Radidumquer- 

 cinum (Jan.), Phlebia contorta (Jan.), Qrandinia granulosa (Jan.), Thelephora 

 arida (Dec. to Mar.) 



The Genus Stereum seems to prefer that time of year, as I have found pur- 

 pureum in Jan., spadiceum in Dec. and Feb., sanguinolentum in Jan. and Apr., 

 rugosum in Dec. and Apr., Hymenochcctc tabacina I have found in Jan., Auri- 

 cularia mesenterica in Feb. The Genus Corticium is also plentiful at that time of 

 year, as the following species, which I have found, will s\io-w,— Corticium, evol- 

 vens (Mar.), giganteum (Dec), lacteum (Mar.), laeve (Jan.), coeruleum (Jan.), 

 cinereum (Jan.), incarnatum (Mar.), nudum (Apr.) ; also Cyphella Curreyi (Mar.)
