12 GUIDE TO THE MODELS OF FUNGI. 



7. Agaricus cepaestipes Sow. — Pileus at first obtusely conical, 

 clothed with separating plumose down ; stalk floccose, bulbous, with 

 a fugacious annulus. 



This species is also an inhabitant of gardens, greenhouses, and 

 stoves, where it usuallj' grows on tan and leaves in densely compacted 

 companies. It is usually a bright sulphur-j^ellow in colour, but 

 frequently white. It is of a soft leathery consistency, and some- 

 what dry. 



8. Agaricus granulosus Batsch. — Pileus and lower part of the 

 stalk covered with a dense, granulose, orange or brownish meal. 



A pretty species, common in woods and open grassy places, 

 lawns, etc. Sometimes it is pure white. 



Sub-genus 3. Ari)iillaria. — There are twelve British species 

 of AnuiUaria ; the models represent different forms of a common 



species, Agaricus melleus. Most of the 

 species are terrestrial, and grow in woods 

 or pastures ; others grow on stumps or 

 tree trunks. The pileus is not warty, as 

 in Amanita, or scaly, as in Lepiota, but 

 often scurfy ; the gills are variously at- 

 tached to the stalk, which is normally 

 furnished with an annulus ; sometimes 

 the annulus is absent, and then Annil- 

 laria is apt to be confused with Tricho- 

 loma. Most of the species are rare. 

 The one modelled is very common.

often downy and scurfy, or beset with 

 small blackish scales ; gills usually adnate, but sometimes more or 

 less decurrent, as shown in Fig. 7 ; flesh yellowish or brownish ; 

 stalk externally rigid, spongy within ; annulus usually large and 

 sulphur-yellow, sometimes small, reduced to a few arachnoid threads, 

 or entirely absent. 



It usually grows in crowded clusters upon or near decaying 

 stumps, or in woods, roadsides, and pastures near trees. It produces 

 a vast number of white spores, which may be sufficiently abundant 

 to whiten the stump on which it grows. Sometimes it grows 

 from long black cords of compact m3'celium termed Rhizomorpha. 

 These black flattened cords are frequently found beneath the bark 

 of old trunks and stumps, but it does not follow that all such 

 growths belong to A. melleus. This species is frequently found on 

 living trees. 



A. melleus is sold in Continental markets, but in Britain it is 

 looked upon as a worthless species for the table. It has caused 

 constriction of the throat when eaten raw.
