or more Interesting Fungi collected during the past year. 97 
of Tulasne’s 1 suspicion that Nciematelia is nothing but a partially 
arrested condition of a Tremella. In cultures the basidiospores 
developed numerous yeast-conidia, which go on budding indefinitely 
in suitable media. 
Another yeast-form which I obtained from pine- twigs at 
Brandon, was investigated at length, and found to develop into 
a form of Ncematelia — or an allied fungus — with orange- coloured, 
beautifully veined, gelatinous thallus, on which pyriform bodies 
resembling chlamydospores arose later. These could not be made 
to germinate, and I regard them as arrested hasidia. Since the 
details are being published, with figures, in the forthcoming 
volume of the Transactions of the British Mycological Society , it 
is unnecessary to go further into the matter here. 
Passing now to the Basidiomycetes proper, I found Exobasidium 
vaccinii, Wor., very common on Vaccinium uliginosum in Scotland 
in September, distorting both leaves and stems, and in many cases 
the deformed pink and white organs were spotted black with a 
Dematium-like fungus which attacks the diseased tissues. 
Hydnum imbricatum , L. 
Apart from its rarity, this fungus is interesting on account of 
its size and beauty. We found it in great quantity near Aviemore, 
and the larger specimens were from eight inches to a foot in 
diameter, though authorities — except Hennings 2 — put the size 
much smaller. Hennings also puts this species into a new genus 
Phceodon on account of its brown spores. I was much impressed 
by the large number of species of Hydnum gathered on Speyside 
this autumn, having myself seen nine, among which this rare 
H. compactum, Pers., is noteworthy if only for the excellence of 
the specimen : I gathered it near Aviemore. 
The rare H. erinaceum , Bull, was sent us from the New 
Forest. 
Boletus sulphur eus, Fr. 
This was found by Mr Plowright of St John’s, during one of 
our botanical excursions in 1899, in a heap of sawdust, and I was 
again with him when he gathered it in the same spot this last 
autumn. 
Strobilomyces strobilaceus, Berk. 
I have twice seen this rare Boletus during the past summer : 
once in Scotland, where Mr Rea showed me a specimen he had 
gathered, and once in Yorkshire, where Mr Crossland showed it 
me in situ.
