The material here referred to this name corresponds well with the description of the species named above except that the spores are not septate, although they sometimes have a pseudoseptate appearance.

Byssonectria fimeti (Cooke) Sacc. Syll Fung. 2: 457. 1883. The species was described from material collected by Ravenel. This material has been examined by the writer and the only ascomycete found was a discomycete. Whether this was mistaken for a Nectria it is difficult to state.

Hypomyces exiguus Pat. Bull. Soc. Myc. France 18: 180. 1902. Stroma byssoid, white; perithecia globose, extruded, scattered, small, 130-160 mic. in diameter, white or slightly yellowish; asci numerous, without paraphyses, cylindrical, 30-35 × 3-4 mic., 8-spored; spores 1-seriate, hyaline, ovoid, smooth, simple, small, 3-4 X 2 mic.

SPECIMENS EXAMINED: New York, Peck (type), Murrill 2678. The spores of this species are similar in size and general appearance to those of Peckiella lateritia but the species is easily distinguished by its bright lemon-yellow stroma.

Stroma effused, more or less cottony, forming an even layer on the hymenium and more rarely on the stem of the host, entirely obliterating the gills, at first white becoming pale yellow or yellowish-brown; perithecia thickly scattered, immersed or with the necks of the ostiola more or less prominent, darker than the subiculum, yellowish or brownish, ovate; asci cylindrical, 8spored, of variable length often attaining a length of 200 mic. ; spores fusiform, usually with a distinct apiculus at each end, unequal sided, at first smooth, becoming delicately verrucose,

hyaline or subhyaline, granular within, nucleate or pseudoseptate, 15-25 X 4-5 mic. (mostly 15-20 X 4-5 mic.) (pl. 21, f. 5).

While this species is usually described as having I-septate spores, there seems to be much difference of opinion on this point. Maire states that he had described Hypomyces Vuilleminianus believing it to differ from Hypomyces lateritius in the absence of the septum of the spores. Having later collected the species commonly and finding the spores to be always non-septate, he began to suspect that the description of Hypomyces lateritius by Tulasnet was incorrect. This suspicion was later confirmed by the examination of the original specimen sent from the Museum of Paris. He therefore reunites Hypomyces Vuilleminianus Maire and Hypomyces lateritius (Fries) Tulasne and states that the spores are verrucose and non-septate. The difference of opinion as to the presence of the septum in the spores of this species seems to be due to the fact that the spore contents often separates toward either end giving a septate appearance.

Hypomyces volemi was described by Dr. Peck on Lactaria volema and the spores indicated as fusiform, 12-15 X 4 mic., and commonly 2-nucleate. I have examined the type of this species and can discover no character on which to separate it.

Peckiella hymenioides was described by the same author on Lactaria uvida and the spores described as simple, subfusiform, pointed or acute at each end, 12-15 X 4-5 mic. Cotype material of this species in good condition has been studied and I find that it conforms in every detail with European material which has been distributed under the name of Hypomyces lateritius (Fries) Tul.

Since making the above notes I have been permitted to examine * Ann. Myc. 4: 331. 1906. Fung. Carp. 3: 63. 1865.

a specimen of Sphaeria lateritia Fries from the herbarium of Fries and this examination has confirmed the observations of Maire that the spores of this species are simple.
