BRITISH FUNGI 



black, soot-like spores, often produced in the " ears " of oats, wheat, 

 barley, etc. Some species belonging to the same group develop 

 in the anthers of living plants. One such is common in the anthers 

 of Lychnis and certain other plants belonging to the pink tribe 

 — Car^-ophyllacea.'. 



The rusts, forming rusty brown or blackish minute dots or streaks, 

 are common on many of our cereals. The hollyhock rust, one of 

 these, forming browii, hard, wart-like spots on living hollyhock 

 leaves, is unfortunately too prevalent ; it also occurs commonh- on

the leaves of our wild mallows. Its name is Puccinia malvacearum. 

 All these forms of fungi should be collected and carefully dried 

 and preserved, for, although not described in this book, the saying 

 that " once a mycologist always a mycologist " is very generally 

 true, and the possession of a collection when the student extends his 

 study will be found most useful. 



The above suggestions as to localities as to wliere fungi are 

 likely to be found is by no means exhaustive. I have found many 

 interesting microscopic forms on old deserted nests of wasps and 

 bees. Finally, during one exceptional season, a fungus foray was 

 held on New Year's Day, when over fort}^ species of the larger fungi 

 were collected.
