Rosenscheldiella pullulans (Berk.) Hansf. 1957
On Astroloma humifusum. Tyors Lake, Victoria, Nov., 1952, R. Melville 1954 in Herb. Kew.

Mycelium penetrating the whole thickness of the host leaf as hyaline, intercellular hyphae, without haustoria in the cells, aggregated in places into irregular, loose columns of tissue between the upper and lower epidermis, which darken at one end to form a solid mass of vertical cells 10-18 x 6-8 µ. This dark mass, when at the upper end of the column extends over the palisade tissue, with small extensions down into this. The dark internal stroma enlarges vertically to burst through the epidermis to extend further as an external stroma up to 50 µ thick. Viewed from above the stroma consists of a tightly packed, irregular mass of rounded to subglobose, perithecioid lobes 120-150 µ diam., black, slightly rough on the surface.

Stromata scattered, amphigenous, often more or less confluent, along the leaf margin, surrounded by the broken epidermis, ¼-¾ mm. diam., or to 1 x ¼ mm. In section each lobe contains a single globose loculus, without a distinct perithecial wall, completely immersed in the stroma tissue, subglobose with conoid apical extension, at maturity 70-90 µ diam. and to 110 µ high, opening by an irregular apical aperture, and surrounded by a dark wall of stroma tissue in 2-5 layers, 20-28 µ thick around the sides, thinner towards the apex, the surface slightly rough by projecting, rounded cells. At the sides these lobes are more or less connate, and with the whole basal half continuous with the external stroma, free above. At first the loculus is about three-quarters filled with a solid mass of delicate, hyaline parenchyma, the upper part with looser short, tortuous, hyaline hyphae, some of which remain in the mature, opened loculus at the apex as short, septate "periphyses". The numerous asci develop at the base of the loculus, and replace almost the entire original contents; erect, narrow ellipsoid to subcylindric, subsessile, rounded at apex and there thickened to 3-4 µ, bi-tunicate, 8-spored, aparaphysate, 38-48 x 9-11 µ. Spores obliquely more or less 2-seriate, hyaline, subfusoid with rounded ends, slightly bent, smooth, 1-septate in middle, not or very slightly constricted, 15-19 x 3-4 µ, cells equal.

Vestergrenia leucopogonis Hansf. 1957
Leafspots none. Perithecia and pycnidia scattered singly, or rarely 2-aggregate, amphigenous, black, raised, smooth, shining, with minute apical pore. Perithecia sunken in leaf mesophyll, with the upper part adnate to the epidermal clypeus, which is black, parenchymatous and to 30 µ thick; perithecia subglobose, 400-500 µ diam. and about 400 µ high, raised above to 250 µ above leaf surface; wall thin, pale brownish outside, composed of elongate cells 10-20 x 5-7 µ, lined by an inner layer of compressed hyaline parenchyma, appearing concentrically fibrous. Young perithecia are filled with erect, hyaline, septate hyphae convergent towards the apex, the lateral hyphae connected to the perithecial wall above and below, the inner hyphae free above, composed of cells 10-15 x 3-4 µ, thin-walled. The apical pore has a thin lining of these same hyphae, not protruding from the apex, which pierces the epidermal clypeus. Asci basal, growing up between the hyphae of the centrum, clavulate-ellipsoid, rounded and thickened to 10 µ at the apex when young and to 5 µ around the sides, subsessile, 8-spored, bitunicate, aparaphysate, up to 95 x 24 µ. Spores 2-3-seriate, hyaline, continuous, ellipsoid with rounded obtuse ends, smooth, 24-26 x 9-13 µ, contents finely granular. Pycnidia similar to the perithecia but smaller, to 270 µ diam. and high; the outermost wall layer olivaceous, parenchymatous, with 2-3 layers of compressed hyaline parenchyma inside, the innermost layer bearing crowded conidiophores. Conidiophores simple, straight, 0-1-septate, hyaline, 16-20 x 3-5 µ, forming single, terminal conidia. Conidia hyaline, globose to wide ovate, thin-walled, smooth, continuous, 11-13 µ diam.
Perithecia et pycnidia amphigena, laxe dispersa, singula vel raro 2-aggregata, atra, elevata, levia, nitentia, immersa; perithecia globosa, 400-500 µ diam., circa 400 µ alt., sursum ad 250 µ elevata et clypeo epidermale, atro, parenchymatico, usque ad 30 µ crasso adnata; paries perithecii tenuus, dilute brunneus, cellulis 10-20 x 5-7 µ, interne concentrice fibrosus, hyalinus, poro apicali pertusus. Asci basali, clavulato-ellipsoidei, apice rotundati et incrassati usque ad 10 µ, subsessili, bitunicati, 8-spori, usque ad 95 x 24 µ, aparaphysati. Sporae hyalinae, continuae, ellipsoideae, obtusae, leves, 24-26 x 9-13 µ, in asco 2-3-seriatae. Pycnidia perithecia consimilia, usque ad 270 µ diam. et alt.; paries 2-3-stratosus, extus brunneus, intus parenchymaticus, hyalinus. Conidiophora recta, simplicia, 0-1 septata, hyalina, 16-20 x 3-5 µ. Conidia singula, terminalia, hyalina, globosa vel late ovata, levia, continua, 11-13 µ diam.
The whole of the mesophyll parenchyma of the leaf. is penetrated by branched, septate, hyaline, intercellular hyphae, which form individual, hemispheric, coralloid-branched haustoria, up to 20 µ diam. in the host cells.
Hab. in foliis Leucopogonis fasciculati, Auckland, New Zealand, Dingley in DSIR 17246.
