Godronia Nemopanthis (Peck) Sacc. 

 On dead branches of N e m o p a n t h u s m ii c r o n a t a (L.) 

 Trel. Newcomb, Essex county. H. D. House, June 20, 1923. On 

 the same collection is also found Sphaeronema Peckii 

 Sacc. (S. caespitosa Peck, not Fckl.) 



Pezicula cinnamomea (Phill.) Sacc. 



This is the same asDermatea cinnamomea Cooke & Peck, 

 and Pezicula eximia Rehm. Doctor Peck's description is 

 incomplete with respect to the spore measurements. He gives them 

 as .0005 in. whereas they are over 30 fx. One was measured 36 x 18 

 //.. In the herbarium Doctor Peck later referred his Sandaken 

 collection (type of Dermatea cinnamomea C. & P.) to 

 Pezicula cinnamomea (Phill.) Sacc, and also at another 

 time to Ocellaria aurea, which has asci 160 /a long, and is 

 referable to Ocellaria ocellata (Pers.) Seaver*, while 

 Pezicula cinnamomea has asci 1 15-20 x 25-28 /x. 



On dead branches of Populus grandidentata Aliclix. 

 Newcomb, Essex county. H. D. House, July i, 1923. East Spring- 

 brook near London, Ontario. Dearncss, July 1912 (type of P. 

 eximia Rehm) . Sandaken. C. H. Peck. On Populus tre- 

 m u 1 o i d e s Alichx. Charlton. C. H. Peck. 



Tympanis Cephalanthi Dearness & House, sp. nov. 



Apothecia black, in clusters of two to four, arising from a thin 

 stroma in the basal stratum of the cortex of the host, cespitosely 

 erumpent through the cuticle, nearly plane. .4 mm wide, .35 mm high, 

 with or in a group of somewhat similar pycnidia. Asci very regu- 

 larly truncate-clavate, 45-60 fx long, 8 yu, across the flat tip, 10-12 /i 

 thick at the broadest part, the upper half crowded with minute 

 sporidia, ascus pore not staining blue \\ath iodine, paraphysate. 

 Sporidia very numerous, minute, hyaline, allantoid, 3-4 x .5-1 jx. 



Karner, Albany county, on dead twigs of C e p h a 1 a n t h u s 

 occidentalis. C. H. Peck (same type material as D e n d r o - 

 phoma Cephalanthi Peck) . 



Most of the units in each group and most of the groups entirely 

 are pycnidia of the Dendrophoma, filled with remarkably 

 much branched conidiophores bearing conidia indistinguishable in 

 size and shape from the conidia of Dendrophoma Cephal- 

 anthi Peck,^ which is seemingly what Doctor Peck described.
