Lachnella anomala (Pers.) G. Cunn. 1963
ARALIACEAE. Neopanax arboreum: Taranaki, Mt. Egmont, 1,100 m. LAURACEAE. Beilschmiedia tawa: Auckland, Mt. Albert, 35 m. MYRTACEAE. Eucalyptus sp.: Auckland, Mt. Albert, 35 m. PAPILIONACEAE. Sophora microphylla: Auckland. Purewa Bush, 35 m. ROSACEAE. Pyrus malus. Auckland. Oratia Research Orchard, 25 m. SAPINDACEAE. Alectryon excelsus: Auckland. Cornwallis, 20 m: Huia, 35.m.
Subiculum annual, arachnoid, fragile, ferruginous or chestnut, effused forming linear areas to 5 x 2 cm. Pilei crowded, sometimes confluent, pyriform, urceolate, or clavate, 300-500 µm diameter, seated on bases which may attain a length twice that of the pilei; pileus exterior clothed with erect abhymenial hairs 2.5-3 µm diameter, filiform with apices inturned or hamate, some inflated, walls yellow brown, densely finely encrusted; margin inrolled, radiate-striate, tomentose; hymenial surface even or pruinose, ferruginous, concave. Context brown, to 80 µm thick, of radiately arranged parallel hyphae; generative hyphae 2-2.5 µm diameter, walls 0.25 µm thick, yellow brown. Hymenial layer to 60 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 24-32 x 6-7 µm, bearing 2-4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses subclavate, 18-26 x 5-6 µm. Spores long-elliptical, ovate, or obovate, apiculate, some obliquely so, 8-11 x 5-6.5 µm, walls smooth, hyaline, 0.5 µm thick.
DISTRIBUTION: Cosmopolitan.
HABITAT: Crowded on bark or decorticated wood of dead branches.
In a former paper I (1953b, p. 178) described the species under the name of Solenia stipitata. W. B. Cooke has advised that this is a synonym of S. anomala. The species may be recognised by the brown, irregularly shaped pilei, and tomentose exterior clothed with filiform, brown, encrusted abhymenial hairs with inturned or hooked apices some of which are apically inflated. Sometimes a second pileus develops from the interior of an older one, plants then being twice or thrice as long. The subiculum may be scanty and arachnoid, or well developed, approaching membranous. The species was made the type of Cyphellopsis Donk and, because of the well developed subiculum and brown hyphae, could well be employed as the type of a small genus to contain L. anomala and other species with these features.
TYPE LOCALITY: Europe.
