NOTES ON THE MYCETOZOA OF LINN^US 163 



burgo adjacente lectus a Frid. Eeinh. Brander inBetulis putridis." 

 Bjorneborg is in the province Abo-Bjorneborg, S.W. Finland. 

 Brader is referred to by Linne as "Magister," probably of Abo 

 University. He may have been a friend of Leche's. The latter 

 (born 1704, died 1764) was Professor of Anatomy and Medicine at 

 Abo University; several sheets from his collection appear in the 

 Linnean Herbarium. 



On the third sheet is a fine specimen of typical Stemonitis 

 splendens Eost. The total height of the sporangia is 14 mm. ; 

 the capillitium has a firm surface-net, with rounded meshes 20 to 

 30 ix diam., attached to the columella by few strong branches. 

 On the sheet is written in pencil " Clathrus nudus," followed by 

 an abbreviation that looks like " Angl." Dr. Jackson thinks the 

 handwriting is that of the Swede, Jonas Dryander, a distinguished 

 pupil of Linne, and that the note was probably made when he and 

 Sir J. E. Smith went over the Linnean Herbarium together in 

 1784-5. It seems unlikely that the doubtful word " Angl " 

 indicates that the specimen came from England, since Stemonitis 

 splendens apparently requires a warmer climate than ours for its 

 perfect development ; the typical form has not been recorded from 

 England, and is rare in Europe ; but is abundant in the United 

 States and in the tropics. 



On the fourth sheet is a weathered specimen of Stemonitis 

 fusca Both., the spores of which, when highly magnified, show 

 characteristic spinulose reticulation, and measure 7 fx. At the 

 head of the sheet Linne has written " Embolus " ; at the base 

 the word " lichenoides " is written in a handwriting which re- 

 sembles that of the great Swiss botanist, Albrecht von Haller, 

 although Dr. Jackson feels that he could not assert that the 

 writing is Haller's." It seems probable that this specimen is the 

 type of Mucor Embolus L., the description of which has been 

 quoted above. 



Within the cover marked " Lycoperdon " are three specimens 

 of Mycetozoa, representing the species Diderma radiatum Lister, 

 Lycogala epidendrum (Linn.) Fries, and Trichia Botrytis Persoon. 



The specimen of Diderma radiatum consists of about eighteen 

 sporangia loosely clustered on five slips of wood. They are either 

 sessile or on short stout brownish stalks ; the sporangium-walls 

 have split into five to ten widely-spreading lobes, pale brown or 

 fawn-coloured on the outside, white within ; from every sporan- 

 gium the capillitium and spores are dispersed, leaving exposed the 

 hemispherical fawn-coloured columella. The sheet is marked, in 

 a handwriting which Dr. Jackson does not recognize, " Lycoperdon 

 radiatum L., Sp. PI. ed. ii. vol. ii. p. 1657, n. 7 " ; below this 

 Eostafinski has written his name. Although Linne has not 

 actually named this specimen, there can hardly be a doubt that it 

 is the type of Lycoperdon radiatum, for, close to one of the slips 

 of wood, he has written in a very small hand the word "filii," 



* Mucor lichenoides L. is a lichen, Calicium quercinum Pers. var. lenticu- 

 tare Nyl.
