Stran 3 - Guide to the British Mycetozoa exhibited in the Department of Botany, British Museum ¡Natural History).
Stran 14 - Spores violet, or violet-brown, except in Stemonitis and Comatricha, in a few species of which they are pale ferruginous.
Stran 7 - Myxomycètes, commonly known as slime-fungi, are minute organisms on the border between the animal and vegetable kingdoms, characterized by the constant sequence of three main stages in their life-history: (1) the firm-walled spore gives birth to a swarmcell; (2) the swarm-cells coalesce to form a wandering plasmodium; (3) the plasmodium concentrates to form either sporangia enclosing numerous spores (Endosporeae), or sporophores with spores on their outer surface (Exosporeae). During the plasmodia...
Stran 10 - Physarttm psittacinum, which inhabits the rotten stumps of old trees, appears to pass...
Stran 10 - ... has risen into a pear-shaped body with a narrow base, a dark stalk being just apparent through the translucent white substance. In...
Stran 11 - The nuclei in the plasma still present the same appearance as those observed in the streaming plasmodium. In about another hour the nuclei show the beginning ot karyokinetic division (Fig. 6); as the process advances the plasma becomes separated in masses of two spores
Stran 8 - ... assumes a globular form ; it then elongates, and a constriction occurs at right angles to the long axis.
Stran 15 - Sporangium-wall membranous, beset with microscopic r.ound granules, and (except in Lindbladia) forming a net in the upper part. Gen. Lindbladia, Cribraria, DU-.tyditim.
