208. Hendersonia elegans. On culms of the common reed. 

 Tansor, Norths. April, 1838. Forming little dark brown spots, 

 in the centre of which is seated a single shining perithecium, 

 the upper part of which causes a little projection above the 

 surface. Perithecia lined with a gelatinous stratum, which 

 gives rise to long broadly fusiform pedunculate colourless 

 spores, with from 6 — 8 dissepiments. Articulations sometimes 

 swollen, often quite even ; each of the central ones containing 

 a single large globose nucleus, with occasionally a few granules. 

 Some of the spores are abortive. 



This most interesting and well-characterized genus I have 

 named after my friend Mr. J. Henderson, who has made many 

 additions to the list of British Fungi, and who is a most in- 

 defatigable and accurate botanist. It is allied to the genus 

 Diplodia, but is well distinguished by the more highly de- 

 veloped spores, which are colourless and pellucid.

 folk. Rev. R. B. Francis, whose plant was supposed at the 

 time of the publication of the English Flora to be G. rufescens, 

 a much more common species. A single specimen has also 

 been found by Mr. Churchill Babington at Clifton, near Not- 

 tingham.

 E. asperulus, Vitt. Mon. Tub. p. 69. t. 4. fig. 6. Vittadini has 

 shown that this genus belongs to the same group as Tuber. I 

 find the structure of the fruit in both our species to agree, 

 except that in the present the sporidia are much larger. The 

 central substance when young is tender and juicy, and consists 



* Other species of this genus are included in Corda's Sporocadus = Di- 

 plodia + Hendersonia, &c. 



The name Sporocadus, though appropriate to true Diplodia, cannot be 

 used for the species now separated under the name of Hendersonia.
