Urceolella deparcula (Karst.) Boud. Karst. Myc. Fenn. I, 150. 
In July rg19 and 1920 Mr James Menzies sent me an abundant 
supply of this beautiful discomycete from the neighbourhood of 
Perth, growing on the dead stems of Spiraea _ulmaria. The 
description of this species given in Massee’s British Fungus 
Flora, Iv, 497, as Belonidium deparculum Massee, is incorrect, 
and the one published by Cooke in Grevillia, xx, 38 should be 
followed as it is a translation of Karsten’s original diagnosis. 
The margin of the receptacle is covered with thin, hyaline, . 
flexuose hairs, 30-40 x I-I-5p at the apex. The asci are 
constantly 4-spored, cylindrically clavate, 30-45 x 5-Op, not 
turning blue with iodine. The spores are hyaline; narrowly 
fusiform, 13-16 x 2m, multi-guttulate. The paraphyses are 
sparse, hyaline, slightly thickened upwards, 25-40 x I p. 
NIPTERA TAXI Rea. 
Ascomata -:2—6 mm. lata, albida, ceracea, gregarea vel sub- 
sparsa, sessilia, hemisphaerica, dein concaviuscula; margineque 
crasso, obtuso; substantia concolor, molliuscula. Asci cylin- 
draceo-clavati, apice obtusi, 50-60 x 8-10, octospori, fora- 
mine immarginato, apice jodo haud tincti. Sporae hyalinae, 
leves, ovato-ellipticae, interdum uno latere subcurvatae, 8— 
I2 X 4p, semper primo continuae, 3-4-guttulatae, denique medio 
septatae, distichae. Paraphyses hyalinae, filiformes, septatae, 
aequales vel ad apicem clava oblonga, aut globosa, interdum 
biseptata terminatae, 55-605 x 2-4. Ad corticem truncorum 
Taxi baccatae in societate Pemtophorae laevigatae, Horsley, Surrey, 
2nd May, 1920. Coll. A. A. Pearson. Distinguished amongst 
the whitish species of Nipterae by the spores constantly 3-4- 
guttulate from the very first and the habitat on bark of Taxus 
baccata. 
Ascocorticium Bref. Bref. Unt. Myk. Ix, 145. 
Receptacle none, hymenium seated directly on the mycelium, 
effused, confluent, and Corticitum-like. Asci small, 8-spored, 
short, broad, sessile, inoperculate, foramen immarginate. Spores 
hyaline, oblong ovoid, agglutinated together in an ovoid cluster 
near the apex of the ascus, and finally ejected together as in 
Saccobolus, but devoid of any surrounding membrane. Para- 
physes sparse, cylindrical, slightly shorter than the asci, scarcely 
enlarged upwards. 
Ascocorticium anomalum (Ellis and Harkness) Schroet. As- 
comyces anomalus Ellis and Harkn. Syn. Ascocorticium 
albidium Bref. in Unt. Myk. 1x, 145, see F. S. Earle in 
Bull. New York Bot. Gard. 11 (1903), 331. 
Greyish white, effused, or in scattered patches, often confluent. 
Asci sessile, clavate or boot shaped, apex obtusely rounded,
