Section Yll. — Peridimn with a radicate strand ; glcha traversed by a definite 
dendroid columella; spores elliptical, coloured, longitudinally ribbed. 
GAUTIERIA Yittadini. 
(After Joseph Gautieri.) 
Plants subglobose, pyriform, or tuberiform, with radicate mycelial strands. 
Peridium either fragile' and in mature plants wanting, or more frequently well 
developed and permanent, of one oi' two layers. Gleba of tramal plates anas- 
tomosed to form labyrinthifonn or cellular cavities lined with a definite palisade 
hvmenium; columella simple or more often dendroid, traversing the gleba; sterile 
base usually present. Spores coloured, elliptical or obovate, longitudinally ribbed; 
basidia 1 to 4-spored, borne on definite sterigmata. Growing superficially or 
partly submerged in vegetable debris. — ^Cunningliani.

400. Gautierla macrospora Gunn. (Gr., malcros, long; spora, seed). Plants 
subglobose or soinewhat irregidar, 4 to lin. (10 to 25 mm.) diametei, pallid 
white with a tinge of bluish green, becoming ochraceous when dried. Peridium 
150 to 200 fj. tliick, of a single layer of pscudoparenchyma and a prominent 
laver of crystals lying next the gleba. Gleba umber brown, cells minute, 2 to 
a'tio 1 mm., filled with spores, aiipearing compact; traversed by ,a branched 
columella arising from a scantv sterile base; tiTunal plates .10 to 80 y thick, 
of woven gelatinized hvqihae, basidia 2-spored. Spores broadly elliptiqal or 
broadly fusiform, 20 to 27 x 11 to 14 y, ferruginous, apex acuminate, base 
shortly pedicellate, ribs about 8 to 10, acute, to 2.5 y tall, vaguely anastomosed.

SECOTIACEAE. 
Plants stipitate, epigacan at maturity. Peridium of 1 or 2 layers, indehiscent. 
Stipe traversing the gleba, and. attached to the periidium at the .apex. Gleba 
of numerous plates anastomosed to enclose cellular or labyrinthifonn cavities , 
capillitiiim absent. Basidia commonly sub-'clavate, forming a pabsade^^bning 
the global cavities, eommionly tetrasporous. 
rough or smooth. — Cunningham. 
Spores ’sterigmate, variously shaped, 
SECOTIUM Kiinze. 
(Gr . seGo.s, a pen or enclosure, in reference to the fruiting body.) 
Peridium variously shaped, of a single pseudoparendiymatous layer ottw 
brightly coloured, indehiscent; carried on a well 
long or attenuated, hollow, stuffed or solid, traversing the gleba and nieigmg
