pycnidium. Finally the column of pycnospores topples over and 
in drops of water the spores quickly disperse. 
Very young excipula are extremely shallow in form, some, 
when measuring 160 pw in diameter and being only 60 » in height, 
were producing a great profusion of conidia. The fungus was 
found on cones of Pinus sylvestris at Tanworth-in-Arden.

Hadrotrichum virescens Sacc. and Roum. var. Poae Sacc. in 
Ann. Mycol. 11 (1904), p. 529. 
This fungus, considered by Saccardo to be the conidial stage 
of Phyllachora Poae (Fuck.) Sacc., was found growing on 
Poa pratensis at Tanworth-in- -Arden. It forms black cindery 
stromata on the leaves. These are at first punctiform but soon 
coalesce to form black patches: the tissue of the leaf round the 
stroma turns yellow and finally the whole leaf dies. 
The dark brown simple clavate conidiophores arise from the 
stroma in fascicles and finally burst through the epidermis. At 
the apex of each conidiophore a single globose conidium is pro- 
duced, measuring 10-12 diameter. 
Penicillium silvaticum Oud. in Arch. Néerl. Sci., Ser. 2, vir 
(1902), p. 289. 
This fungus was first recorded by Oudemans for Holland and 
later by Jensen (Cornell Univ. Agric. Exp. Stat. Bull. No. 315 
(1912)) for America. It is interesting to note that the specimen 
was growing in a Petri-dish culture of agar, a situation very 
similar to that recorded by Oudemans. Jensen had found it 
amongst the soil fungi which he had isolated and it is very 
probable that the specimen found in the Botany Laboratory of 
Birmingham University was a result of an infection from soil 
brought into the department. 
The mycelium which was pale sepia brown consisted of sterile 
branched septate hyphae from 3-6y thick, and erect fertile
