Peridiii pale yellow, ,\ -\ mm. diiim., globose, somewhat scattered 

 or oecasioiially agL'Togatt'd in a loose cluster, sessile, composed of 

 loosely interwoven septate torulose ])ale yellow threads, the separate 

 cells of which ai-e usually shaped like those of a Sphcpvozosma (e.g. 

 S. excavatam) ; a few spiral or irregulaidy tlexuose hypha? project 

 beyond the boundary of tlie sphere. Within is an enormous number 

 of globose asci, forming a deeper yellow central mass, permeated by a 

 few slender septate hyphje, each ascus containing 8 spores. Asco- 

 spores lens-shaped, ciivular in front view, 2-8 /u diam., elliptic in 

 side view, \\ /x thick, at length faintly verruculose. 



On feathers buried in soil, and on fragments of the soil itself. 

 Birmingham. June, July 1919. 



These are on the same feathers on which, in March 191-1, 1 found 

 Dacfj/lella pi u mi cola, described in this Journal for 191(3, p. 220 

 (])1. oli-l f. 1 ). They were left in the same closed tin box, to which 

 a few drops of distilled water wei-e added every twelve months or so. 

 At the end of the live years, on the decayed remnants of the feathers, 

 the Ctenomifces was observed, but the DacttjleUa had disappeared. 

 Xo comb-like structures had been seen. No conidia had been formed 

 on separate hyphte, nor were any found on the torulose hypha^ of the 

 peridium. The asci are very delicate and easily diffluent, but, just 

 as in Eurotlum lierhariGriim and its allies, their presence is shown 

 by the fact that large numbers of the spores remain in globose 

 crowded masses, in which for tlie most part seven spores can easilv 

 be counted, the eighth being hidden behind the others. 



In a few cases, the torulose h^^pha? of the peridiuiu have the pro- 

 tuberance almost wholly on one side. The " hakenformig " or 

 " krallenf ormig " hyplue, from which the name C/<??iowyc«°s is derived, 

 is only an exaggeration of that arrangement, and its absence can 

 scarcely be regarded as a specific difference. 



This fungus has been previously recorded as British by Miss A. 

 L. Smith ( Joarn. Bot. 1908, p. 257) ; the ascospores are, however, 

 described by her as " cylindrical, about 2 X 1 ;«,." It has also been 

 found by Dr. Jessie Bayliss Elliott, who in addition met with the 

 supposed conidia.

Stroma (distinct from the mati-ix) none. Perithecia immersed 

 in the unchanged parenchyma of the cortex, and entirely covered bv 

 the periderm, placed in a circle (more or less) round a disc which k 

 at first cinereous then pallid-brown, or round a pycnidium {Cytospora)^ 

 minute, globose, erect, with a short neck ending in a round smooth 

 black ostiole, which at length pierces the epidermis at some distance 

 (|-1 mm.) from the disc or spermogone. Asci clavate or oblon«>-» 

 attenuated below, wall rather thick especially at the apex, 8-spored, 

 72x8 /M (average). Spores cylindrical, straight, or curved in profile, 

 subdistichous or conglobated, 10-20 X 8-4 /x (average Kiya).

These specimens exactly resemble the German ones. They are 

 easily distinguished by the fact that the more or less irregular "circle 

 of perithecial necks pierces the epidermis directly upwards, and
