Crossland : Fungus Foray at Mulgrave Woods.

The moist clayey banks in the woods appeared to be appre- 

 ciated by the Clavariae ; of these no fewer than thirteen species 

 were gathered, including - a stranger which is being worked out. 

 Tremellinese were few, as were also the Gastromycetes. Not 

 many species of parasitic fungi were noted ; probably there 

 were more, but not seen. Rhytisma acerinum was extremely 

 prevalent on sycamore leaves ; even seedlings had their very 

 first pair of real leaves blotched by it. Primrose plants were so 

 rank that one felt sure of being able to find its leaf disease 

 Pucciuia primula?, and there it was. Phragmidiu7n mucronatitm, 

 along with a few other things, was seen on a cultivated rose 

 tree in the lodge garden at Lythe. A stroll into an adjoining 

 garden resulted in the haulms of some diseased potatoes being 

 boxed for closer examination ; on these were found Vermicularia 

 atramentaria B. & Br. , Volutella ciliata Fr., and Colletotrichum 

 lycopersici Chester. Respecting the latter Mr. Massee reports 

 as follows : — ' Colletotrichum lycopersici Chester, now for the 

 first time recorded as a European fungus, is recognised as 

 a parasite on tomatoes in the United States. In this country it 

 was first observed as a destructive parasite on potato-haulms in 

 a field near Worcester a few weeks ago (August 1900), and has 

 since been observed on the same host, which it had killed, in 

 a cottage garden at Lythe. The diseased stems are blackened 

 as if scorched, and as they were left on the ground the pro- 

 bability, almost amounting to a certainty, is that not only will 

 the disease appear again next season, but that it will also extend 

 its range.' 



The smaller Discomycetes were fairly abundant, and included 

 two very special things, viz., Dasyscypha Richonii Mass. = Tri- 

 chopeziza Richonii Sacc, new to Britain, and Diplocarpa 

 Curreyana Mass. = Peziza diplocarpa Currey. The fortunate 

 find by Mr. Gibbs of this apparently rare and most peculiar 

 Oiscomycete affords an opportunity of confirming the accuracy 

 of the author's original description of the character and length 

 of the spores. Subsequent descriptions, taken from herbarium 

 material, have, from some cause or another, extended the length 

 a little beyond the real. There does not appear to have been 

 any other record since Currey first found it at Joyden's Wood, 

 Hartford, until the present. 



There was an almost entire absence of the larger Pezizae, 

 excepting the somewhat loeal Galact iuia succosa. 



On account of the immense quantity of fallen timber and 

 branches Pyrenomycetes will abound in the earl) part of any
