Slugs as Mycophagists. A. H. R. Buller. 271 
clinging. Some other fruit-bodies, e.g. Russula ochroleuca, 
Lactarius piperatus and L. turpis, were almost equally damaged. 
The following species were found to have been visited and 
partially eaten by slugs: 
Species attacked by Slugs. 
Amanita rubescens. Laccaria laccata. 
Amanitopsis vaginata. Hypholoma fasciculare. 
Clitocybe clavipes. H. sublateritium. 
Russula emetica. Flammula sapinea. 
R. ochroleuca. Paxillus involutus. 
R. sardonia. Cortinarius anomalus. 
R. heterophylla. C. paleaceus. 
R. nigricans. C. caninus. 
R. adusta. ; C. rigidus. 
Lactarius piperatus. Boletus flavus. 
L. subdulcis. B. chrysenteron. 
L. glyciosmus. B. scaber. 
L. turpis. Clavaria cinerea. 
The following species were found not to have been eaten by 
slugs: 
Species not attacked by Slugs. 
Lactarius quietus. Inocybe geophylla. 
L. rufus. Tubaria furfuracea. 
Collybia butyracea. Cortinarius sanguineus. 
Flammula inopus. Polystictus versicolor. 
Inocybe asterospora. Lycoperdon pyriforme. 
Of the species attacked, some, e.g. the Russulae, were damaged 
much more than others. Scarcely a single fruit-body of any 
species of Russula could be found which had not been partially 
eaten. Very few of the fruit-bodies of Hypholoma fasciculare, 
Laccaria laccata and Lactarius glyciosmus had been eaten and 
these only slightly, so that it seems that slugs do not much 
relish these species. 
Of the species not attacked by slugs only single fruit-bodies 
were found of Flammula inopus, Inocybe asterospora and Cor- 
tinarius sanguineus, and a few fruit-bodies only of the relatively 
tiny Inocybe geophylla and Tubaria furfuracea, so that it is 
possible that, if the fruit-bodies of these fungi had been more 
numerous, some of them might have been found attacked. The 
species which seemed to have been definitely avoided by slugs 
were Lactarius quietus, L. rufus, Collybia butyracea, Polystictus 
versicolor and Lycoperdon pyriforme*. 
Two species of slugs were found upon the fungi, a larger 
* These five species are also distasteful to human beings.
