162. NEW OR CRITICAL FUNGI. present species, and in many other instances, do not agree with those given by Berkeley for the same species. These discrepancies may be reconciled when we remember that the methods employed in making microscopic measurements were not so accurate thirty or forty years ago as at the present day. Hypocrea (Hypocrella) axillaris Cooke, Grev. xx. 4 ; Australian Fungi, 279. On grasses. Queensland. This species is identical with Hypocrdla BambiiscB (B. & Br.) Sacc. Michel, i. 323; Syll. Fung. xi. no. 5064; hence the first- mentioned name should be given as a synonym of the second. H. BambuscB was previously recorded only from Ceylon. Dothidea Alyxise Mass. Perithecia (8-12) caBspitose and con- fluent, forming a black, convex pustule which originates beneath the epidermis, black, shining, glabrous, 2-3 mm. across, mouths of the perithecia rather large and partly open ; asci subcylindrical, apex rounded, base narrowed into a short stout pedicel, 8-spored, 100 X 11-12 fjL] spores obhquely 1-seriate, elliptical ends very obtuse, 1-septate, cells equal in size, brown, translucent, 18 x 10/x; paraphyses absent. On living leaves of Alyxia huxifoUa K. Brown. Tasmania. Readily distinguished by the narrowly cylindrical asci, the spores being 1-seriate in the ascus, and in having the two cells of equal size. Microthyrimn Psychotriae Mass. Perithecia scattered, hypo- phyllous, orbicular, discoid, almost plane, smooth, blackish brown, opaque, 100-125 /x diameter, mouth distinct and slightly prominent; asci clavate, shortly stipitate, 45-50 X 6-7 /x, 8-spored ; spores irregularly 2-seriate, hyaline, SQiooth, narrowly clavate, 1-septate below the middle, 7-8 x 2-5 x 3 /a. On the under surface of living leaves of Psychotria suhpunctata Hiern. West Tropical Africa, lat. 1° N. (Coll. G. Maim, no. 1814). The minute perithecia are uniformly scattered over the under surface of the leaf, and were supposed by Hiern to be black points in the tissue peculiar to the species, hence his specific name. Sterigmatocystis vitellina Eidley (PI. 357, figs. 14-16). Entire fungus 2-3 cm. high, composed of numerous erect, aseptate hyphae 10-12 /x thick, which are arranged in a compact, parallel fascicle for some distance upwards from the base, becoming free from each other and spreading to form a lax tassel at the apex, each hypha being terminated by a globose or broadly pyriform head 80-100 /x diameter; apical swelling of the hypha 18-22 //, diameter, giving origin to densely packed, radiating, narrowly clavate basidia 15-18 /x long, and about 4 /x thick at the apex, which bears 3-5 conical sterigmata 6-8 /x long ; each sterigma in turn bears a single subglobose conidium at its apex about 4 ^ diameter. Colour of every part of the fungus bright egg-yellow. Gregarious on the fallen pericarps of some undetermined fruit. Singapore, H. N. Ridley,
