Pilocratera tricholoma (Mont.) P. Henn., forma — fig. 4. 

 Ascomatibus profunde urceolatis, 1—2 cm. diam., nmic sessilibus, 

 nunc stipite tenui, 3 mm. long, 1 mm. crass, suffultis, flavidis vel flavido- 

 isabellinis, disco paulo obscuriore, extus costis longitudinaliter e basi in 

 cupulam porrectis anastomosantibus venoso-rugosis, pruinosis, setis rigidis, 

 concoloribus, ad i — 5 mm. altis, inprimis circa marginem obsessis. Setis 

 simplicibus, coremiiformibus, ad basim usque 135// crass., apicem versus 

 leniter attenuatis, ex hyphis dense septatis, 4 — 6 /u crassis, compositis. 



Ascis perfecte cylindraceis, crasse 

 tunicatis, superne rotundatis, in- 

 feme in hypham ascigeram su- 

 bito transeuntibus, 270—340 // 

 X 16 — 19 /i. Sporidiis ellip- 

 soideis , utrinque acutiusculis, 

 continuis, 1-pluriguttulatis, crasse 

 tunicatis, 30 — 37 fj. x 13 — 15«, 

 hyalinis. Paraphysibus tenuissi- 

 mis, ramosis, ascos obvallantibus, 

 in fasciculos coremiiformes, ple- 

 rumque 12/i crass, conglutinatis, 

 apicibus liberiS; subclavatis, flavi- 

 dulis. J. -T-. 



Ad Jignum corticatum in 

 monte Mt. Felix dicto Novae 

 Granatae (leg. Eggers) et in 

 silva insulae Trinidad. (Leg. H. 

 Lassen). 



Our specimens of the above 

 species, which has been hitherto 

 somewhat incompletely described, 

 are differing from the type espe- 

 cially as to dimensions of the 

 spores (30— 37/i x 13 — 15/i 

 against 30 /i X 10 /i). 



To judge from the descrip- 

 tion Pilocratera Engleriana P. 

 Henn. is quite identical with 

 P. tricholoma as to the macroscopical appearance, and in microscopical 

 regards it is only differing by having the spores somewhat broader (14 — 17//); 

 by comparing, however, the form above diagnosed, which is found in the 

 middle of the American area of P. tricholoma and undoubtedly is to be 

 conferred to this species — it seems justified to suppose that also
