230 PETCH : 



on the stalk, the pycnospores measuring 14-16 x 1-6-2 '5 [h ; in 

 the pulvinate forms the pycnidia are irregular, and in one example 

 the centre of the stroma is convoluted, with deep sinuses, resem- 

 bling an Aleyrodid Aschersonin ; the descriiDtion and measurement 

 of the spores given by Hennings is that of the jjycnospores. The 

 type of Hypocrella ochracea Massee, in Herb. Kew, contains 

 Glaziou 18,806, 18,811, and 18,812, and urmumbered duplicates; 

 18,811 and 18,812 are apparently on the same plant, while 18,806 

 and the duplicates are on two other different plants ; on the leaf 

 18,806 there are two species, the Aschersonia stage of H. phyl- 

 logena and Aschersonia turbinata ; specimen 18,812 is an Aleyrodi 

 Aschersonia, Aschersonia Goldiana Sacc. & Ellis ; the duplicates 

 contain Hypocrella phyllogena, with ascospores up to 20 x 3 ji, and 

 pycnospores with shorter tips than usual, and purple-red sterile 

 specimens which are apparently the same ; a packet marked 

 ascigerous by Massee contains one specimen, evidently the same 

 as those in 18,811 and the duplicates. In Herb. Paris Glaziou 

 18,811 is included under Hypocrella phyllogena, while in Herb. 

 Berlin it is placed under H. Edwalliana ; the sjoecies is the same 

 throughout. In the type of ^. Wcherhauri'P. Henn., Weberbaur 

 No. 3,601 in Herb. Berlin, the specimens are stud-shaped and up 

 to 3 mm. diameter ; the head is hemispherical, smooth, slightly 

 grooved round the margin, brownish or ochraceous ; the stalk 

 is short, and the hypothallus either scarcely exceeds the diameter 

 of the head or extends 2 mm. beyond it ; the groove between the 

 hypothallus and the head is very narrow and deep ; the 

 part-sj)ores measure 14-20 x l'5-2 \x, and are either curved 

 or straight, and sometimes inflated in the middle ; some of the 

 specimens are greenish ; a note by the collector (?) states that the 

 "thallus" is orange coloured. Hypocrella coronata v. Hohnel 

 agrees with H. phyllogena, except in one respect ; a specimen 

 supplied by von Hohnel has a diameter of 4- 5 mm. without the 

 hypothallus, and 8 mm. including the hypothallus ; it is pale 

 yellow, discoid, 1 • 5 mm. high, dei^ressed in the centre, with a 

 slight groove at the base ; the upper surface is verrucose, and 

 bears numerous tapering, conical appendages, often curved, up 

 to 1 mm. long, iisually arising from near the ostiola ; the sjDores 

 are wound in a flat spiral, and the part-spores are cylindric, 

 slightly ovoid, 9-12 x 2-2 • 5 [x ; it differs from H. qohyllogema only 

 in possessing these appendages, but the same form occurs in the 

 type specimen of H. sulphurea in Herb. Berlin (MoUer, 286). 

 Under Moelleriella (Hypocrella) sulphurea Bres., in Herb. Berlin, 

 are two collections, one, the type, MoUer 28b, St. Cathar. Blu- 

 menau, and the other from E. IJle ; both are H. phyllogena. 

 Hypocrea amazonica Cke, type in Herb. Kew, Spruce No. 528, 

 contains Aschersonia basicystis, A. discijormis, and an unnamed 

 purple-brown Aschersonia. Specimens collected by Rick, Fungi 

 Austro-Americani No. 294, Sao Leopoldo 1907, were assigned 

 to Hypocrella vcrruculosa by Theissen, and are included under 

 that name in Herb. Berlin, while others of the same collection 

 have been lent me by Theissen ; this collection contains two 

 forms, the one normal H. phyllogena, with the head smooth or
