Hhizophagus cribratus, Oyll.., in the Derwent Valley. — Yesterday morning 

 I was pleased to find Rhizophagus cribratus, GylL, at Brock well, a low-lying and 

 marshy wood near Winlaton, which I have not previously searched. The Rhizo- 

 phagus occurred in powder-covered agarices growing on a dead oak tree, and 

 amongst other species taken I should mention Tetratoma fungorum, which tumbled 

 out of these fungi in some profusion. This reminds me that my friend Mr. Gardner 

 has met with jR. cribratus in the Hartlepool district, and he tells me that he look 

 his examples from beneath dried cowdung ; but, of course, it may be that the 

 Rhizophagus in question affected some fungoid growth thus situated. The species 

 of Rhizophagus which have occurred in the Derwent Valley are, R. cribratus, Gyll., 

 R. depressus, F., R. perforatus, Er. (Gibside and Winlaton Mill), B, parallelocollis, 

 Er. (old churchyard at Winlaton), R. ferrngineus, Pk., R. dispar, Pk., R. bipustu- 

 latus, F., and the very rare R. coeruleipennis, Sahib, (near Gibside) ; whilst of the 

 remaining three British species, R. nitidulus, ¥., and R. politus, Hellw., may yet be 

 found with us,— R. S. Bagnall, Winlaton : October 8th, 1906. 



Rhizophagus parallelocollis, Er., taken in a grave. — Mr. De la Garde's note in 

 last month's Ent. Mo. Mag. on Rhizophagus perforatus, Er., has reminded me that 

 I took two specimens of its near ally R. parallelocollis, Er., last year in what is most 

 probably its most frequent habitat, viz., a grave. (See Canon Fowler's note, " The 

 Worm ? that Devoureth," in Ent. Mo. Mag., vol. xxiv, p. 276). I happened to be 

 passing our well-filled churchyard when a new grave was being dug. The grave- 

 digger had got down about six feet and was just unearthing a very old skeleton 

 which had obviously not been disturbed before. When examining a leg-bone, which 

 was a most interesting pathological specimen, I came across the above beetles, which 

 had evidently been dead for a very long time. — Norman H. Joy, Bradfield, near 

 Reading : October 7th, 1906.
