CAMPOSPORIUM MARYLANDICUM SHEARER FROM BRITAIN

C. T. INGOLD

Birkbeck College, London

In numerous samples of stream foam collected inEngland, Scotland and Wales I have found conidiaof Camposporium pellucidum (Grove) Hughesalthough never in large numbers. Further, thisfungus has been found sporulating on a completelysubmerged decaying leaf of alder (Ingold, 1975).It is, however, well known as a terrestrial species(Ellis, 1971). In conidia from foam the single

terminal, hyaline appendix tends to be ratherlong (100-150 jlm). The main part of the conidiumis bright brown with septa sharply defined.

Shearer (1974) described a new species C.marylandicum from balsa wood submerged in thefreshwater part of the Patuxent River flowing intoChesapeake Bay in the U.S.A.

Notes and brief articles 533collection in F.A.A.) from the Ledard Burn fourmiles west of Aberfoyle, Perthshire, Scotland,conidia were found dearly belonging to Shearer'sspecies. Both species of Camposporium occurredin this sample (Fig. 1) As compared with conidiaof C. pellucidum those of C. marylandicum have amain section that is completely unpigmented,shorter, more fusiform, narrower and with fewersepta. Further, the whole conidium is more deli-cate and the septa are so thin that they are quitedifficult to make out, in striking contrast to thoseof C. pellucidum. The terminal appendix mayreach a length of 180 pm. This is considerably

greater than in Shearer's description (33'5-80 pm).However, not much significance is attached to thisas the length of the appendix is so variable inC. pellucidum.

NEW SPECIES OF ALEURIA AND WYNNEA FROM INDIA

K. S. WARAITCH*

Department of Plant Pathology,Punjab Agricultural University, Ludhiana, India

Many collections of Pezizales were made during1964 from the Darjeeling Hills, Eastern Himalayas.Some of these are new records for India whileothers represent undescribed species. A fewrecords have already been published elsewhere(Thind & Waraitch, 1970, 1971a, b, 1974) whilenew species of Aleuria and Wynnea are beingdescribed in this paper. The fruit bodies havebeen described from fresh collections supple-mented by preserved dried and formalin-alcoholpreserved material. The anatomical details arebased on free-hand and microtome sections.Material is deposited in the herbarium of theBotany Department, Panjab University, Chan-digarh, India (PAN) and the Royal BotanicGardens, Kew (K).
