GUIDE TO THE MODELS OF FUNGI. 



f,l 



GENUS XII.—LENTINUS Fr. 



In Lentinus the species are distinctly cartilaginous-leathery, 

 generally irregular in growth, with the gills minutely toothed or 

 torn at the edge, sometimes requiring a 

 lens to detect the serration. The British 

 species grow on stumps and trunks, and, 

 though not brightly coloured plants, are 

 attractive and often beautiful. There are 

 eleven British species of Lentinus, only 

 one of which is represented by a model. 



115. Lentinus tigrinus Fr.— Pileus 

 creamy-whitish, variegated with blackish, 

 hairy squamules, fleshy-leathery, thin, 

 convexo-plane, umbilicate, at length in- 

 fundibuliform, often split at the margin 

 when dry; gills decurrent, narrow, crowded, pi^. 4,._Lentinus cochieatus Fr. 



unequal, toothed, white ; stalk thin, solid, (One-quarter natural size.) 



hard, attenuated downwards, squamulose, creamy-white, fuscous at 

 the base, furnished at the apex with an entire, reflexed, fugacious 

 ring. 



L. tigrimis is rare and grows upon stumps, old trunks, and 

 branches in a gregarious or caespitose manner. Acrid, odour strong. 



ORDER II.— POLYPORE^. 



In the PoJyporece the under surface of the pileus is covered with 

 small, closely packed tubes. The tubes are lined with cells named 

 basidia, bearing spores in groups of four in the same manner as in 

 the Agaricincce (see fig. i, page 7). The species are fleshy, leathery, 

 or woody. There are 211 British species, nineteen of which are 

 represented by models. 



GENUS XIII.— BOLETUS Dill. 



In Boletus the spongy mass of small, vertical, closely packed 

 tubes is easily separated from the under surface of the pileus. All 

 the species have central stems, and are fleshy and putrescent. They 

 are terrestrial, and many are esculent. In the edible species the 

 tubes should be scraped away before cooking. There are forty-nine 

 British species of Boletus, thirteen of which are represented by 

 models. 



116. Boletus luteus Fr. — Pileus yellowish, smeared with a 

 separable brown glutinous covering, gibbous, then pulvinate; flesh 

 white; tubes adnate ; pores minute, simple, yellow; stalk equal, 

 firm, whitish, rough with dots above the large, membranaceous, 



white-brown ring.
