about six inches apart through the hark on the central surface of the 

 log ; one of these developed sporangia, and the other formed a 

 schlerotium which remained in situ for about ten days, and then 

 disappeared apparently into the wood ; we have observed that i^las- 

 modia vv^ill at times disap|>ear in this manner. 



The log at the present time (August 1920) is still hard, although 

 showing some signs of decay, j^et it has been lying in the same 

 place in this conifer plantation for eight years. The entire dis- 

 appearance of the two fungi, Bulc/aria lyolifmorplia and Cori/ne sar- 

 coides, first referred to and the abundant growth of the Mycetozoon 

 Physarum nutans in precisely the same place lead us to the conclu- 

 sion that their mycelia were absorbed and destroyed during the 

 plasmodial stage of the Mycetozoon, for it is well known that these 

 oro-ani.^ms can thrive on mycelium : probably the plasmodium thrived 

 on the mycelium for about three years before it proceeded to the 

 stase of fructification. 



SHOUT NOTES. 



SciLLA CAArPANULATA Ait. (p. 22). I have known the area 

 between Truro and Pei-ranporth intimately for ^^ears and remember 

 clearly a strong garden Scilla which grew like a weed in a garden 

 near Perranzabuloe Cimrch, and strayed from the garden into hedge- 

 banks outside ; it may be the same species. Another plant which 

 strays out of bounds and bids fair to become a permanent element in 

 our flora is Oofoneasfer Slmonsii Hort. A bush planted in Perranza- 

 buloe churchyard some forty years ago has given rise to thriving 

 bushes (bird-sown, no doubt) in several spots within half a mile. 

 These were recorded by Mr.W. Tresidder some years ago, and recently 

 I noticed thriving young plants in the neighbourhood of planted 

 bushes at Silverwell in the next parish. — F. Rilstone. 



Arum riALicuM Mill, in Sussex. At the latter end of May 

 this year I had an opportunity of examining a fresh specimen of this 

 species from West Sussex, a fine clump having been found near 

 Arundel by Mrs. and Miss D. Powell. As far as I am aware, the 

 only other station in the county is in the Broadwater neighbourhood 

 (Arnold, Fl. Suss. 75, 1887). The flowering stem examined was 

 about 18 inches tall with a spathe of 13 inches ; the yellow spadix, 

 measuring about 5 cm., v/as noticeably longer than its naked peduncle ; 

 the barren filaments were warty at the base ; and the cluster of 

 fertile ovaries were much longer in proportion to the ring of stamens 

 than in A. macvlatiim. The leaves, which were not particularly 

 white-veined, had the diverging and projecting lobes characteristic 

 of Miller's species. The above features are those specially remarked 

 upon by Boreau, Coste and Rouy, the first author noting that the 

 leaves are only rarely veined with white in the area of his Avork 

 (Fl. Cent. Fr. ed. 3, ii. 736, 1857). Townsend (Fl. Hants, 327, 

 1883) described the Isle of Wight plant as a new variety, iieglectuni, 

 having leaves more frequently sjjotted, their apex more rounded, and 

 the basal lobes less triangula'r and less spreading. The Arundel 

 specimen did not agree with this description. — C. E. Salmojs.
