Ascomatibus gregariis, sessilibus, juvenilibus cupulatis, rnaturis dis- 

 coideo-explanatis, disco subconvexo, carnosulis, ad IbOju diam., flavidis 

 vel (in sicco) succineis, extus glabris. Ascis cylindraceo-clavatis, sessilibus, 

 43 — 56/^ X i^U — 6^/2 fji, sporidia nonnumquam 8, saspius — nonnullis 

 frustratis — pauciora foventibus. Sporidiis oblique monostichis, fusifor- 

 mibus, utrinqiie acutiuscule rotundatis, primo bi-guttulatis, ad maturitatem 

 medio 1-septatis, non constrictis, IOV2 — 14// X 2^/2— 3'^/4/^, hyalinis. 

 Paraphysibus filiformibus, aseptatis, circ. 1 ju crass., hyalinis, superne in 

 clavulam usque bju crassam, substantia oleosa, flavida repletam subito 

 dilatatis, ascos parum superantibus. Membrana tota ascorum nee non 

 paraphysibus jodi ope intense coerulescentibus.

Lembosia Agaves Earle. 



Our spores have at the full-ripe 

 stage (totally brown) an average size 

 of 17 — 20// X 7—9// (against 14 — 

 16// X 6 — 7// in Earles diagnose). 

 The young asci are strongly thickened 

 in the apex.

a: Ascomata; 6: Vertical section through an 

 ascoma; c: Asci with paraphyses; d: Spores, 

 (a and b; circ. ^"/i; c and d: "•■•"li). 



Our fungus on leaves of Sac- 

 charum officinarum shows quite the 



same characteristic macroscopical aspect as the above species, what also 

 has been confirmed by comparing a type specimen of L. saccharicola 

 Henn., benevolently committed to us by the Botanical Museum of Berlin. 

 — Our asci are a little narrower (8 — 10// against 12 — 15//) and the 

 spores somewhat broader (5 — 5^/2// against 4//) as stated in Hennings' 

 description of the species; unfortunately the type specimen examined did 

 not contain any asci. 



A type specimen of SphaeruUna Sacchari P. Henn., likewise sent 

 to us from Berlin, is thoroughly identic with the above species as to the
