Hypomyccs 7iiiliarius, Tul. This species consists of a thin white layer of 

 mycelium running over the gills, and sometimes other superficial parts of various 

 Bussxdce (JR. emctica, fcetcns, and adusta). From this mycelium are produced erect 

 conidiophores, which bear abundant narrow ovate oblong conidia '004- "013 mm. in 

 length. Intermixed with the mycelium are innumerable small globose sclerotia.

Hypomyces tubcrosus, Tul., is a much larger plant than the preceding. The 

 sclerotia are large, globose or irregular, whitish or pallid, and externally a, good 

 deal resembling those from which Agaricus cirrhatus is developed, but there ;s this 

 very marked difference between these two sclerotia — those of the agaric, when cut 

 across, are pale yellow within, while those of the so-called Hypomyccs are reddish 

 brown. My friend M. Cornu, last autumn, gave me some fresh sclerotia of the 

 latter kind, which I placed in incisions in the stem of a specimen of Lactafius 

 vellercus and kept under a bell-glass. In due course, the sclerotia developed a 

 beautiful mould consisting of a central stem, which, in the course of a few days 

 from its first appearance, grew to the height of 2 to 3 cm., and gave off, at right 

 angles, branches bearing oval hyaline spores. The branches were very numerous, 

 nearly at right angles to the central stem, not arranged in whorls. The erect 

 direction of the stem soon became lost, and the branches interlaced with those of 

 other specimens, so that an intricate mass was formed, from which was developed 

 a fresh crop of sclerotia.

There remain two species of Hypocrea which, only after mature consider- 

 ation, have been excluded from the present monograph, namely H. alutacea and 

 H. inclusa, B. & Br. The former is a well-known plant which has been figured 

 and described by various authors under the generic designations of Hypocrea, Cor- 

 dyceps, Claviccps, Sphceria, and Clavaria. As usually found in this country, it 

 bears a stronger external resemblance to the Torruhice, than to the members 

 of any other genus. Its fructification, however, clearly shows its affinity to the 

 Hypocrece. Its aaci contain eight uniseptate hyaline sporidia, which at maturity 

 fall into two separate halves at the septum, so as to appear as sixteen globose 

 sporidia arranged in a linear series. 



M. Tulasne regards this species as an ally of the Hypomyccs, and considers it 

 parasitic upon Clavaria ligula. Now Clavaria ligula is not, properly speaking, an 

 English species, for although within the last few years it has been recorded from 

 Scotland, it has not as yet been met with south of the Dee. In searching for 

 Hypocrea alutacea, some few years ago, near Hereford, Mr. C. E. Broome casually 

 mentioned the fact that he frequently found it growing in company with Spathu- 

 laria fiavida, and since which time I have found it several times, but always 

 associated with the Spathularia, except on one occasion. So intimate and perti- 

 nacious has this association been that I cannot doubt its parasitism. The other 

 occasion, alluded to above, was near King's Lynn, when it occurred upon an old 

 stump, and although I cannot recognize the host upon which it grew (any more
