or more Interesting Fungi collected during the past year. 97 



of Tulasne's 1 suspicion that Namiatelia 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 Namnatelia — 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 basidia. 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 piuk 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. 1 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 sulphureus, 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.
