or more Interesting Fungi collected during the past year. 99 



Hypholoma appendicidatus, Bull. 



This again cannot be regarded as rare, but I obtained speci- 

 mens in October of a form regarded by an excellent judge as a 

 Bolbitius. This is interesting because Hypholoma hydrophilus, 

 Bull, a form very close to H. appendicidatus, Bull, was named 

 Bolbitius by Fries. 



I have germinated the spores, and find their behaviour agrees 

 in all essential respects with that of the species of Hypholoma 

 investigated by Brefeld 1 , and in a fortnight or so I obtained 

 excellent cultures of the characteristic tufts of oidia, thus adding 

 one more to the list of Basidiomycetes which produce secondary 

 asexual spores of this description. 



Stropharia albocyanea, Desm. 



Recorded in Stevenson 2 as " uncommon," is by no means rare 

 in Cambridgeshire and Norfolk. S. aeruginosa, Curt., also com- 

 mon, sprang from mycelium on Asparagus roots brought in by 

 Mr Hill, and which I cultivated in the laboratory this summer : 

 it appeared to be parasitic. Geaster mammosus, Chev., has been 

 found at Brandon by Mr Biffen, and we find 0. fimbriatus, Fr., 

 common at Wimpole and elsewhere in the County. Sphcero- 

 bolus stellatus, Tode, is also abundant, as well as Crucibidum 

 vidgare, Tul. More remarkable are Nididaria confluens, Fr., and 

 N. pisiformis, Tul., both from Shouldham in Norfolk, where I have 

 seen the former in great abundance in a cart-rut. N. pisiformis is 

 instructive as showing how a Nididaria may be derived from such 

 a form as Octaviana if the sporangial chambers of the latter 

 become more individualised. Mutinus caninus, Fr., was sent us by 

 Dr Plo wright, to whom I owe much for specimens and inform- 

 ation. 



The beautiful exotic Dictyophora phalloidea was brought by 

 Mr Yapp from the Malay Peninsula. 



Among the rarer or more noteworthy species of larger Fungi 

 which have come under my observation during the past year may 

 be mentioned the following, gathered by various members of the 

 British Mycological Society during a few days' collecting in com- 

 pany with Dr Keith, Dr Stevenson, Dr Plowright and others in 

 Rothiemurchus Forest and neighbourhood last September.
